Preface

Since Apple introduced its proprietary "blade" SSD in 2010, changing hard drives has not been that simple!

When Apple launched computers with its own SSD and promoted its excellent reading and writing speed experience, it rarely mentioned the details of the SSD standard technology used by any company or even any product other than Apple. Simply put, this SSD is a pluggable SSD specification defined by Apple.

This custom interface specification, many people mistakenly believe that it is one of the variants of M.2, but so far, Apple has not used the standard M.2 connector. What is even more confusing is that Apple has never given it to itself. The interface has a name.

Although some Apple computer products retain the possibility of upgrading SSDs, this "you can change but you can't buy" situation makes some Apple computer users very uncomfortable. The use of small-capacity computers is very frustrating, and the installation of ordinary solid-state products is risky. Changing to genuine large-capacity solid-state products directly caused Apple to dissuade the company from high replacement costs.

In this issue of SanDisk’s evaluation, the tested product comes from KingSpec’s NA900S. Let’s take a look at the performance of the SSD suitable for Apple computers. Let's first look at what it looks like.

Introduction to the appearance of KingSpec's NA900S

The packaging of KingSpec's NA900S is exquisite and compact, and the configuration characteristics of this hard drive are briefly introduced on the packaging box. For example, model NA900S, supports PCIe Gen 3*4 interface, 2TB capacity, and 3 years warranty. This time we got two solids.

KingSpec's NA900S products include a total of: NA900S, a plastic packaging box, and a manual. NA900S uses a single-sided thin and light design, which is very friendly to the solid-state upgrade of Apple notebooks and all-in-one computers. The specification is 24mm*89mm. To

Tear off the label paper, you can see the internal structure. What everyone cares most about the internal structure is the particles. To

This NA900S Apple dedicated SSD uses Ziguang’s original 3D TLC flash memory particles, with a total of four on the substrate, with a single capacity of 256GB; the main control chip is Huirong’s 2263XT, which is a non-cached main control chip, part of the solid state of the first-line brand Products are also used. In the storage industry, Huirong Technology is currently one of the more mature companies in the master chip solution, and it is trustworthy.

In order to ensure the product use experience, NA900S can rest assured in terms of materials, quality control and quality.

Ultra-stable performance characteristics

Next, let's conduct a comprehensive test of KingSpec's NA900S on the machine to see what the most eye-catching features of this NA900S Apple-specific SSD are.

Since this is an Apple-specific SSD, ordinary solid-state interfaces are not compatible, so when testing, we will use adapters, for the test results, it may have a little impact, but the impact is not significant.

ASSD test

The test capacities are: 128GB, 256GB, 512GB, 1TB, 2TB

From the test results, it can be seen that the continuous read speed of KingSpec 2TB NA900S is about 2825MB/S, the continuous write speed is about 2510MB/S, and the total score is 4449. This read and write speed is very suitable for system disks or work disks. After the upgrade, the old Apple machine can be radiant.

To sum up

Judging from the synthesis of multiple test results, the biggest application feature of KingSpec's NA900S is its excellent stability. For users who need to deal with small files frequently, stable performance has a more obvious effect on improving work efficiency.

For KingSpec’s NA900S, I think it’s reasonable to describe its performance as "extreme experience". High-quality product selection, mature product solutions, powerful 4K read and write performance, ultra-stable small file read and write performance, and ample SLC cache space. For those who are still using old Apple machines to work, this The product allows them to make a qualitative leap based on the experience of the original Apple products, not only in terms of speed, but also in capacity.

This KingSpec NA900S also has four capacities of 128GB/256GB/512GB/1TB /2TB, and a three-year warranty service. Interested friends can enter the KingSpec official website or view related products, or you can leave a message below for more related Apple SSD issues to communicate together.
