SSD Memory USB Drives Memory Card

How do I know the exact capacity?(SSD)

The capacity is shown in "Megabyte" (same with Hard Disk Drive, 1MB = 1000KB). In Windows environment or DOS mode, 1MB equals to 1024 KB.  Therefore 1GB is approximate 953MB.

The actual available memory on the device is less than what is listed on the package. This is due to small discrepancies in file format and algorithms used by various operating systems. In addition, a portion of memory space is reserved for system files and data sectors for better performance.

What is difference between with HDD and SSD?

HDDs are based on magnetic spinning platters, a technology that has been in use since the mid- 1950s. The data is written to and read from these spinning platters or disks via moving heads. HDDs are mechanical devices with many moving parts and are more prone to mechanical failures and failures due to environmental conditions such as heat, cold, shock and vibration.

SSD is made of NAND Flash, controller chip, DDR and other semiconductor materials, which are pasted on the PCB board through the patch process, no mechanical parts, high speed, low latency, low power consumption, quiet.

Can I transfer data or OS from an existing HDD to a new SSD?

Yes. KingSpec SSD drives in upgrade kits that include all the necessary items required to replace a notebook or desktop HDD with a KingSpec SSD, including software to easily transfer the OS and important data. Please note that SSD-only SKUs do not include the software. If you need to clone your HDD to a new SSD you will need the bundle kit.

My SSD is a SATA 3 drive and my motherboard only supports SATA 2. Will my SSD work with my motherboard?

Yes, it is backwards compatible, but it will be running your motherboard’s SATA 2 rated speeds.


S.M.A.R.T stands for “Self-Monitor and Report Technology”, is built in hard drives and solid-state drives to indicate condition of drives. All Kingspec SSD series support S.M.A.R.T. The S.M.A.R.T contains Average P/E Cycle Count, Total Power-on Time, Power-on Cycle Count, Total Host Writes/Read and other specific information.

Viewing SMART information requires third-party software (such as CrystalDiskInfo) or the Linux command smartctl, etc.

What is NVMe?

NVMe stands for Non-Volatile Memory Express. Non-Volatile Memory means that it does not require power to retain information.NVMe takes advantage of pipeline-rich, random-access, memory-based storage. It provides significantly higher data transfer rates than traditional disk interfaces such as SAS and SATA.

What interfaces can NVMe be used with?

The NVMe protocol can be used with most standard interfaces which includes M.2 / PCIe / and SATA express.

Is an M.2 SSD the same as an mSATA SSD?

No, they are different; M.2 supports both SATA and PCIe storage interface options, while mSATA is SATA only. Physically, they look different and cannot be plugged into the same system connectors. 

What is the difference between consumer and industrial SSDs?

The application fields served by consumer SSDs tend to be individual consumers, such as personal computers, notebooks, DIY, e-sports, film and television, etc. The application fields served by industrial-grade SSDs tend to be industrial fields, such as IPC, electricity, energy, finance, big data, servers, security monitoring, blockchain, cloud computing, education, retail, netcom, medical care, rail transit, etc.

What interfaces does KINGSPEC's industrial-grade SSDs have?

KINGSPEC industrial-grade solid-state drives include: 2.5-inch SATA, mSATA, M.2 SATA, NVMe, 2.5-inch PATA, SATA DOM, IDE DOM, 1.8-inch ZIF, U.2 PCIe, HALFSLIM, CFAST, CF, CFEXPRESS and other interfaces. Compared with INNDISK, APCER, ADATA, PQI, TRANSEND and other industrial brand SSDs, KINGSPEC has more obvious various types of interface solid state drives, and KINGSPEC has short delivery time, high cost performance and high-quality service.

Why is there a difference between the actual capacity and the labeled capacity of an SSD?

The difference between the actual and marked capacity of an SSD comes from a few key factors. Manufacturers use the decimal system (1 GB = 1,000,000,000 bytes), while operating systems use the binary system (1 GiB = 1,073,741,824 bytes). Some space is also taken up by file system structures and metadata, called formatting overhead. Additionally, a part of the SSD is reserved for maintenance tasks like wear leveling and bad block management, known as over-provisioning. These factors combined result in a lower actual usable capacity than the marked capacity.

What is Solid State Drive (SSD)

SSD, namely Solid State Drive, is a revolutionary storage device. It comprises NAND flash and other components, which are quite different from the traditional hard disk drive. Its advantages are obvious. It has extremely fast speed, which can make the system start and program loading completed in an instant. Moreover, it is quiet without any noise from the mechanical hard drive. It also has good shock resistance, which strongly guarantees data security. Because of this, SSD is widely used in various computer systems and has become a key component to improve system performance.

Do I need to install a driver before installing an SSD?

1. When the SSD is SATA, since the corresponding driver is built in Windows 7, 10, and 11, at this time, there is no need to install any third-party driver. 

2. When the SSD is NVMe, when using Windows 7 and 8 systems, the NVMe driver needs to be installed, while in Windows 10 and 11, the system integrates the driver for PCIe SSD.

What is the difference between SATA II and SATA III?

The main differences between SATA II and SATA III lie in their data transfer rates, bandwidth, and features. SATA II supports a maximum data transfer rate of 3 Gbps, while SATA III doubles this rate to 6 Gbps. This increased speed in SATA III makes it better suited for modern SSDs and high-performance HDDs. SATA III also offers improved data handling, better error correction, and enhanced power management compared to SATA II. While both are backward compatible, meaning SATA III devices can connect to SATA II interfaces and vice versa, they will operate at the slower speed of the interface they are connected to. 

What is TRIM?

TRIM is a system command in which the Windows 7 operating system informs an SSD about data blocks that are no longer needed and can be erased to free up space. This function is akin to garbage collection and is performed during idle times to enhance performance.

Why am I unable to transfer a file that is 4GB or larger to my SSD?

The inability to transfer a file that is 4GB or larger to your SSD is likely due to the file system being used. If your SSD is formatted with the FAT32 file system, it has a maximum file size limit of 4GB. To transfer larger files, you would need to reformat the SSD to a file system that supports larger file sizes, such as NTFS or exFAT.

How to Check if TRIM is Enabled on Your SSD

1. Open Command Prompt:

   - Press `Win + R` to open the Run dialog box.

   - Type `cmd` and press Enter to open the Command Prompt.

2. Check TRIM Status:

   - In the Command Prompt window, type `fsutil behavior query DisableDeleteNotify` and press Enter.

3. Interpret the Result:

   - If the result shows `DisableDeleteNotify = 0`, TRIM is enabled.

   - If the result shows `DisableDeleteNotify = 1`, TRIM is not enabled.

What is the difference between P3 and P4?

Only the capacity differs; the performance is the same. The P3 uses TLC chip, while the P4 uses QLC chip.

What is the difference between PCIe 3.0, 4.0, and 5.0?

PCIe 3.0: 

- Data Transfer Rate: 8 GT/s per lane

- Bandwidth: ~1 GB/s per lane in each direction

PCIe 4.0: 

- Data Transfer Rate: 16 GT/s per lane

- Bandwidth: ~2 GB/s per lane in each direction

PCIe 5.0: 

- Data Transfer Rate: 32 GT/s per lane

- Bandwidth: ~4 GB/s per lane in each direction

Each new generation doubles the data transfer rate and bandwidth of the previous one, allowing for higher performance and faster data processing.

What is the difference between XG7000 and XG7000 PRO

The XG7000 variant does not come with independent cache but features a thin physical profile with a graphene heat dissipation label. In contrast, the XG7000 Pro comes with independent cache, offering superior performance and includes a metal heat dissipation vest. It is more suitable for esports enthusiasts. For specific specifications, please refer to the details provided on the official website.

My SSD's actual test speed does not match the specifications?

Due to variations in parameter settings, testing methods, and testing environments used by different software, it's common to observe differences in read and write speeds for the same SSD on the same platform with different testing software.

Ensure that the BIOS is configured with the SATA option set to AHCI Mode. However, if it was originally set to IDE mode, it's advisable not to enable AHCI as it may cause booting issues. AHCI mode should ideally be enabled before installing the operating system, except for Windows 7, which may require manual loading of the AHCI driver.

Manually update the AHCI driver to the latest version, which can be downloaded from the official websites of AMD, Intel, depending on your chipset model. For Intel chipset users, installing Intel Matrix Storage is recommended.

Utilize the ATTO Disk Benchmark tool for testing. Depending on your chipset model, download the driver from the official websites of AMD, Intel.

What is ECC?

ECC (Error Correcting Code) automatically identifies and rectifies data corruption that occurs during reading, writing, storage, transmission, or processing. This technology guarantees more reliable and secure data transmission.

How do I install Microsoft Windows 7 on a PCIe NVMe SSD?

Both Windows 10 and Windows 8.1 systems offer built-in support for PCIe NVMe SSDs, featuring drivers packaged within the operating systems to ensure compatibility with these drives.

Similarly, the latest Ubuntu and other Linux distributions come equipped with drivers that seamlessly support PCIe NVMe drives.

KingSpec PCIe NVMe SSDs are compatible with standard Windows (8.1 or later), Intel iRST, or Linux NVMe drivers. Special drivers are unnecessary for installing the operating system on a KingSpec SSD.

Conversely, native Windows 7 does not recognize or function with PCIe NVMe SSDs, nor does it provide in-box drivers for them. Should you desire to install the Windows 7 system on a PCIe NVMe SSD, please refer to the provided link or consult Microsoft for further assistance. Microsoft Support for Installing Windows 7 on NVMe SSDs

What are the advantages of SSDs over HDD?

SSDs excel in high-speed data transfer, low power consumption, exceptional durability, silent operation, and resilience to low temperatures.

Will data be kept after I update the firmware of my SSD with SSD Scope?

Before updating the firmware of your SSD with SSD Scope, please ensure you have a backup of your data, as it may be erased during the update process.

How do I determine if the product is included in the warranty?

Please refer to KingSpec’s warranty policy. If you need to check the product warranty, please go to warranty policy page.

Why is golden fingers turned black considered human error?

The gold fingers usually turn black because of an incorrect plug-in or due to contaminants inside the motherboard connector.

When I buy a 128G SSD, why does the disk's capacity not reach 128G

The calculation of HDDs and SSDs differs. In an HDD, 1GB equals 1,000,000,000 bytes , whereas in an SSD, 1GB equals 1,073,741,824 bytes. This difference in calculation methods results in SSDs appearing to have 7.37% less capacity than HDDs.

Additionally, SSDs reserve some capacity for the controller to run algorithms such as ECC (Error Correcting Code) and wear leveling. This reserved space acts as a buffer to enhance the performance and longevity of the SSD.

M.2 SSD Installation Instructions

1. Kindly power down the computer and disconnect the power cable.

2. Locate the M.2 SSD slot on the motherboard.

Given that motherboard designs vary, please consult the motherboard's user manual for precise guidance.

3. Insert the M.2 SSD.

Before installing the M.2 SSD product, ensure to remove any heat spreader or screws on the motherboard, and verify that the M.2 SSD aligns with the slot interface.

Note: Remove all screws from the M.2 SSD slot and ensure no other obstructions are present.

When installing the SSD, firmly grasp both sides of the M.2 SSD product and align the connector with the slot notch. Then, insert it into the M.2 Slot at a 20-degree angle and fasten it into the mounting holes on the motherboard.

Is it necessary to initialize a brand new SSD?

As we cannot predict users' operating systems or how they intend to use the SSD, we refrain from initializing and formatting the SSD before it leaves the factory. Upon first use, please ensure to initialize and format your SSD according to your operating system, whether it be Windows, Mac, or Linux. This ensures the SSD operates normally and is compatible with your system.

Why is my computer unable to recognize my M.2 NVMe SSD?

There are numerous potential causes for your computer's inability to detect your SSD. Please refer to the checklist below to troubleshoot the issue:


Ensure that your motherboard supports NVMe SSDs, as the M.2 interface has multiple signals and may only support one of them.

Check whether your motherboard's platform controller hub (PCH) has adequate channels for NVMe SSDs.


Confirm that your BIOS supports NVMe SSDs and is properly configured to recognize them.

Operating System (OS):

Verify that your operating system supports NVMe SSDs. Note that native support for NVMe SSDs is not available in Windows 7.

If the M.2 port on my motherboard supports only PCIe Gen3×1 speeds, is it compatible with PCIe Gen3×2 or ×4 SSDs?

If the M.2 port on your motherboard only supports PCIe Gen3×1 speeds, it is technically compatible with PCIe Gen3×2 or ×4 SSDs, but the SSD will operate at the reduced Gen3×1 speed.

How many kinds of sockets and keys are there for M.2, and how can one confirm interface compatibility?

M.2 sockets have different keys (B, M, and B+M), and you can confirm interface compatibility by ensuring the key type and protocol (SATA or NVMe) of your M.2 device match those supported by your motherboard's M.2 slot.

I need drivers for SSD

SSD can run without drivers

Where do I get software to clone my old drive?

Please transfer data with DiskGenius

Is ECC memory compatible with a standard motherboard?

ECC memory can be used on a standard motherboard, but the ECC function will be disabled, causing it to operate as non-ECC memory. However, compatibility varies, and on some motherboards, using ECC memory may result in instability or boot issues. Always check your motherboard's specifications to ensure compatibility.

What is Rank?

"Rank" refers to a set of DRAM chips connected to the same chip select line and can be accessed simultaneously by the memory controller. Each rank has a width of 64 bits (72 bits for ECC memory). The concept of rank is determined by the memory controller and DRAM chip specifications, rather than the number of chips on the module. Ranks are independent of whether the memory module is single-sided or double-sided. For instance, eight 8-bit DRAM chips or four 16-bit DRAM chips can form one rank. A rank is essentially a unique, independently addressable 64-bit data area within a memory module, as defined by JEDEC standards.

Is the lighting control software for RGB memory compatible with the motherboard?

Currently, KingSpec RGB memory supports the lighting control software of four major motherboard manufacturers. We recommend consulting third-party customer service to confirm software compatibility if you wish to use additional RGB control software.

What is XMP?

Extreme Memory Profile (XMP) is a technology designed to enable the overclocking feature of compatible DDR3 or DDR4 RAM, allowing for enhanced performance beyond standard specifications. 

What is the performance difference between memory timing and CAS latency (CL)?

Higher memory timings generally result in better performance, while lower CAS latency (CL) is preferred for improved efficiency. Overclocking can further enhance performance, but it's crucial to consider both memory timings and CAS latency. Normal users may opt for RAM with higher memory timings while overclocking enthusiasts should carefully evaluate both memory timings and CL. However, RAM with overclocking features tends to be more expensive. 

What is Serial Presence Detect (SPD)

SPD is a standardized mechanism used in modern computer memory modules (DIMMs) to provide essential information about the module to the system BIOS. This information includes details such as the module's manufacturer, capacity, speed, voltage requirements, and supported memory timings. SPD is stored in a small EEPROM (Electrically Erasable Programmable Read-Only Memory) chip on the memory module itself. When the system boots up, the BIOS reads the SPD data to automatically configure memory settings, ensuring optimal compatibility and performance without the need for manual intervention.

Why does the system only detect half of the installed memory?

Some older version motherboards may not support newer memory modules, resulting in the system being unable to detect the correct memory capacity. 

Is DDR4 2400MT/s RDIMM backwards compatible with DDR4 2133MT/s platforms?

Yes. In most cases, DDR4 2400MT/s modules are compatible with platforms designed for 2133. However, the maximum speed of the module is only 2133MT/s.

What should I do if I encounter the message "Windows was unable to complete the format" or "Write Protection" while using a USB drive?

Please repeat the process on another computer. If you encounter the same error message, the flash drive may be damaged. Please reach out to KingSpec's Customer Service for assistance with the issue

What should I do if my antivirus software scans and finds a virus on my flash drive?

First, ensure to back up your files and proceed to format your flash drive. Formatting will erase all data, including any viruses present. If a virus reappears after formatting, it's likely that your computer is infected and the virus is being reintroduced. In such cases, it's important to address the virus on your computer to prevent it from infecting your flash drive again. Contact your computer maintenance vendor or antivirus software company for assistance in resolving the infection issue.

When is it safe to remove a USB drive from a computer?

It is safe to remove a USB drive from a computer after ensuring that the operating system prompts for safe removal of the device. In the Windows operating system, you can click on the notification icon in the taskbar at the bottom right corner, locate the USB device, right-click on it, and select "Safely Remove Hardware and Eject Media". 

What should I do if I get an error message about loss of data stream while transferring data?

The "Stream Loss" error message commonly appears when transferring data from an NTFS-formatted storage device to a FAT or FAT32-formatted Flash drive. Typically, encountering a "Stream Loss" message does not lead to data loss or damage, allowing you to proceed without concern. This error message automatically generates a "Thumbs.db" file in a folder using the NTFS format. However, deleting the "Thumbs.db" file before copying the folder will prevent this error message from occurring.

What if I can't copy a 6GB sized file to an 8GB sized flash drive?

Before transferring files, it's essential to check your file system format. Keep in mind that the FAT16 format supports individual file sizes up to 2 GB, while FAT32 allows up to 4 GB. For files exceeding 8 GB (including 8 GB), utilizing the NTFS or exFAT file format is necessary. Make sure your file system format is compatible with the size of the files you intend to transfer.

What are the differences between USB 1.0, USB 1.1, USB 2.0, USB 3.0, USB 3.1, and USB 3.2?

USB 1.0, USB 1.1, and USB 2.0 are earlier versions with progressively faster data transfer speeds. USB 3.0 introduced SuperSpeed with faster transfer rates. USB 3.1 and USB 3.2 offer even faster speeds and additional features like USB-C connectivity.

Certainly, here are the speeds associated with each USB version in megabytes per second (MB/s):

- USB 1.0: Up to 1.5 MB/s

- USB 1.1: Up to 1.5 MB/s

- USB 2.0: Up to 60 MB/s

- USB 3.0: Up to 600 MB/s

- USB 3.1: Up to 1000 MB/s

- USB 3.2: Up to 20Gbps

What is USB 3.2?

USB 3.2 is the latest iteration of the USB (Universal Serial Bus) standard, offering even faster data transfer speeds and improved connectivity options compared to previous versions. USB 3.2 supports data transfer rates of up to 20 Gbps, making it significantly faster than its predecessors. Additionally, USB 3.2 introduces new features such as USB Type-C connectivity and improved power delivery capabilities, making it a versatile and efficient choice for modern computing needs.


OTG stands for "USB On-The-Go." It allows smartphones or tablets to connect directly to USB peripherals, acting as a host without needing a computer.

Why can't I access files larger than 4GB on my USB drive?

If you can't access files larger than 4GB, your USB drive is likely formatted as FAT32, which has a 4GB file size limit. To fix this, back up your data and reformat the drive to exFAT or NTFS using these steps:

Connect the USB drive and open File Explorer.

Right-click the drive and select "Format."

Choose exFAT or NTFS as the file system.

Click "Start" to format.

This will allow you to store files larger than 4GB.

Why does the “Insufficient Space” message appear when copying files to the USB disk, despite having enough space?

This issue often arises due to limitations of the FAT file system. Many manufacturers format USB disks in the FAT format. When attempting to copy over 255 files to the USB disk simultaneously, this restriction can trigger the error message. To address this, you can either create a new folder or re-format the USB disk to FAT32 or exFAT. However, it's worth noting that FAT format is the most compatible with most operating systems.

How can I determine if a CF card is in Fixed Disk Mode or Removable Disk Mode?

When the CF card is accessed using IDE or SATA through an adapter or extension board, if the CF card is displayed as a local disk, it is in Fixed Disk Mode. If it is displayed as a removable disk, it is in Removable Disk Mode.

Why does my camera stop video recording despite enough remaining storage on the card?

1. Ensure that the video recording time limit is set, not a fixed duration.

2. If the card format is FAT32, recording stops when it reaches 4GB due to file size limitations. Switching the card format to NTFS or exFAT, if supported, can resolve this issue.

Why does the capacity of the memory card displayed on the computer always appear lower than the actual capacity?

The capacity of a memory card displayed on the computer might appear lower than its actual capacity due to various factors such as file system overhead, formatting, and marketing practices. File systems like FAT32 or exFAT reserve a portion of the storage for file allocation tables and metadata, reducing the usable capacity. Additionally, marketing conventions often use decimal-based calculations (1GB = 1,000,000,000 bytes) while computers use binary-based calculations (1GB = 1,073,741,824 bytes), further contributing to the perceived difference in capacity.

How do I choose the right memory card for my requirements?

To select the right memory card:

1. Check compatibility with your device.

2. Choose an appropriate capacity and speed class.

3. Ensure compatibility with your device's file system.

What is the difference between CF card/ CFast card and CFexpress card

CF cards are older and slower, typically used in older devices. CFast cards are faster and more compact, suitable for professional cameras. CFexpress cards offer the highest speeds and capacities, ideal for demanding applications in modern devices.

CFast cannot be formatted on the Canon 1DX Mark 2.

CFast cannot be formatted on Canon 1DX Mark 2 due to a camera-specific bug. This issue also affects CFast cards from other brands. Formatting may be necessary using an adapter board.
