SD capacities are increasing with pricing becoming more economical. This is good news for system builders, as you not only get speed but enough space to pack in your applications and games as well. After looking at Corsiar SSDs couple of months back, we have yet another 256GB SSD in our midst-the ADATA XPG SX900 256GB SSD.
It comes in an all-black brushed aluminium finish body and has a 9.5mm thickness making it deal to be used even inside a laptop. There are 16x16GB MLC NAND chips, eight on each side of the PCB along with a SandForce SF2281 controller. You get around 238 GB of usable space.
We tested the SSD on our standard rig comprising an Intel Core i7-3770k processor. ASRockZ77 Extreme 4 motherboard, 8GB Kingston DDR3 RAM and so on. Crystal DiskMark 3.0 gave as sequential read /Write score of 366/368.6MB/s which is lower than the Corsair Neutron GTX 240 GB drive. AS-SSD gave 4k read /write speeds 19.15/47.24 MB/s which was slower than both the Corsair Neutron GTX, as well as Neutron SSDs. The random read/write performance was at par with Intel Series 335 SSD. While transferring within the drive , we got sequential/assorted file transfer speeds of 155.65/129.12MB/s which is again lower than that seen on the Corsair SSDs where as Intel Series 335 SSDs is faster with assorted transfers.
At $248,it offers a very good cost per GB of $1,which is lower than the Corsair SSDs. If you are fine with comparatively slower speeds, this SSD gives you great value for money.
