Newegg currently has the SX900 128GB in stock for $114.99. 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. Our 128GB SX900 has a claimed sequential read speed of 550MB/s and a sequential write speed of 520MB/s. TRIM support is listed as a feature and for the first time with this model, it's actually true. This is a big positive after seeing a handful of manufacturers give a blanket set of performance numbers for all the capacity sizes. Looking over the ADATA XPG SX900 spec sheet, we see that ADATA broke the drives performance down by capacity size. 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. 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. 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.
