Specifications, Pricing and Availability
OCZ is taking Vertex 3.20 to only two capacity sizes - the 240GB model we're looking at today and the 120GB model, which you can read about in a few days. Both capacity sizes share the same sequential read (550MB/s) and sequential write (520MB/s) performance. The 120GB Vertex 3.20 has a lower IOPS rating, 20K read and 40K write. The 256GB drive has 35K read and 65K IOPS write.
As we mentioned in the introduction, the new Vertex 3.20 uses the same LSI SandForce SF-2281 as the original Vertex 3. There are just a couple of changes - the largest is the new 20nm IMFT flash. Then the firmware, OCZ had to use a 5-Series firmware from LSI to use 20nm flash with the controller. Finally the packaging has changed and now reflects the value minded placement in the OCZ line up. That means you now get the drive only, no desktop adapter bracket.
Newegg already shows the two new Vertex 3.20 drives in stock. The Vertex 3.20 120GB sells for $114.99 and the 240GB model sells for $219.99. At the time of writing Newegg still had the original Vertex 3 120GB in stock ($119.99), but not the 240GB model. We suspect 25nm IMFT flash is drying up, just like 24nm Toshiba Toggle did a couple of months ago.
