Storage area changed its past tediousness in 2008, the continually price dropping on DDR2 memory and high capacity hard disk bring consumers climax, it decreased DIY cost efficaciously, at the other side, SSD which stands the future developing trend is thriving. At the beginning of the year, the first SSD using on ThinkPad X300 have drawn people's attention, new changes came out while difficulties have been overcame. Lots of manufacturers entered into the SSD activity after that. In order to be the precedent of this new time, we received KingSpec SSD which of form factors 2.5", capacity 32GB (Item SD-SA25.2-032MJ) It is quoted at 499RMB, Comparing to products of same specifications, its Performance Price Ratio is quite outstanding.
KingSpec SSD shows us its light weight on the first view, it is 65g in total. It is almost absent while it's put in the package so that it brings us convenience when it is fixed in a notebook. Volume of KingSpec SSD is exactly the same with traditional HDD, its dimension is 100.2mm*69.8mm*9.5mm. It is also possible to installed as a moveable disk.
Contrast between KSD-SA25.2-032MJ; 3.5"desk hard disk and 2.5" notebook disk
The material of KSD-SA25.2-032MJ is ABS environmental plastic casing which is compliant with RoHS standard. Although milk-white casing is not that slippery feel with metal casing, it plays roles on protection. As in introduction, KSD-SA25.2-032MJ can resist lash as large as 2000G.. It can endure shaken at 20G. during working, working temperature is 0-70 degree.
It has 4 metal pieces around its frame which is to fix the connection with its heart. It has standard SATA interface and power supplying interface. Official data showed that MTBF of disk arrived 1 million hours, duration is as long as 40 years. We haven't dismantled SSD because of the time issue.
Evaluating flat
We chose two flats, the ones which effected performance of disk is the ICH8R of Intel and newest SB750, 965pcs flats installed 4 groups disk (Seagate 1TB RAID,Western Digital 1TB,Seagate 320GB and KingSpec SSD where system placed), AMD flat is Seagate 1TB green version and KingSpec SSD.
We chose bottom software HD Tune Pro which under the next item of HDD in PCMark Vantage, and the file testing item of Sisotware, We inspected the performance of SSD synthetically, meanwhile, we made comparisons with lots of traditional disks.
Testing result
KingSpec SSD has different curves in both flats, though the rest 965 are more stable, the average speed exceeding traditional disk, the minimal speed arrives 112MB/s too.
Flat Intel testing condition of reading and writing
Flat AMD testing condition of reading and writing
The performance of KingSpec SSD is very good on writing speed, which is of average speed of 49.5MB/s, we can see from the following picture that the writing and reading speed of the disk is not stable enough, but its access time got an amazing 0.2ms.
In test of SiSoftware, we have contrasted for the 4 disks, RAID Redundant Array of Independent Disks is superior obviously. However KingSpec SSD is very stable, its performance is very higher than Western Digital 1TB and Seagate 320GB desk traditional disk.
PCMark Vantage is standard tool to test complete performance, thereinto specific disk testing is including Windows Defender, <<Alan Wake>>game, picture inserting, Windows Vista startup, Video editing, Media player center using, Windows Media Player searching and sorting. It also includes the following startup: Office Word 2007,Adobe Photoshop CS2,Internet Explorer,Outlook 2007 and so on. KingSpec SSD gained 11295 marks, it is quite satisfying that exceed plenty of then traditional disks.
At last we have a simple test on Crysis wardhead train, KingSpec showed 38 seconds, RAID is 60 seconds, the distance is quite obvious.
Evaluating Sum up
The 32GB KingSpec SSD has totally showed the priority on Solid State Disk, KingSpec SSD is better on performance, heat and noise compare to traditional desk disk. It will improve the whole performance while being used in notebook. As a new comer of SSD market, the quality of KingSpec products is quite satisfying. Along with the decreasing trend of basic cost of SSD, high capacity SSD replacing the traditional HDD will be one of the most expectant industries in the future.
