Specifications, Pricing and Availability
ADATA released the SX900 in four capacity sizes - 64GB, 128GB, 256GB and 512GB. At this time we can't say how many of the capacity sizes will get the B02/20nm make over, but we know the 128GB model already has it. Our sample shipped from the ADATA warehouse in California so there is no guarantee your drive from an e-tailer will be the new revision.
So, how can you tell if your SX900 has the new low power B02 controller, you ask? The only real way is to open the case and look for yourself because the new drive, and the old drive, look identical. They even share the same model number. As far as ADATA is concerned, it's the same drive, but someone looking to run RAID with an older SX900 and a new SX900 will care because the new third of a quarter size PCB and number of flash chips don't performance the exact same. In the same vein, someone looking for B02 battery life performance, a 20 to 30 minute increase in our Lenovo W530 with a six-cell battery, would like to know what drive he or she are actually using as well.
Looking over the ADATA XPG SX900 spec sheet, we see that ADATA broke the drives performance down by capacity size. This is a big positive after seeing a handful of manufacturers give a blanket set of performance numbers for all the capacity sizes. TRIM support is listed as a feature and for the first time with this model, it's actually true.
Our 128GB SX900 has a claimed sequential read speed of 550MB/s and a sequential write speed of 520MB/s. ADATA lists performance for AS-SSD and calls it Multimedia Data Transfer, but since AS-SSD uses incompressible data, we'd call it incompressible data performance since not all media is compressed to the same levels SandForce's architecture compresses to and not all compressed data is media data.
Newegg currently has the SX900 128GB in stock for $114.99. They also have the other capacity sizes - 64GB ($79.99), 256GB ($199.99) and 512GB ($389.99). All XPG SX900 models have a three year warranty, Acronis True Image HD Data Migration Software (via download), desktop adapter bracket, mounting screws and a paper manual.
ADATA just announced their entire SSD product line would convert over to a 7mm z-height. Our sample shipped in a 9.5mm package so it may take a bit of time for the existing stock to move to the new 7mm package. Yes, yet another potential version of the SX900.
