OCZ's original Z-Drive was one of the first PCIe connected SSDs to appear and came in versions aimed at enterprise and desktop users, with some versions (based on more expensive SLC NAND flash memory) claiming maximum read and write speeds of 800MB/s and 750MB/s respectively.
This week OCZ announced the follow up to the Z-Drive; the Z-Drive R2. The main change over the original is the move to a setup that uses NAND modules that can easily be added or removed from the main board (they look much like notebook RAM slots). That means the R2 can be upgraded or serviced in the field, an advantage for the enterprise users it is aimed at. It also boasts an eight way RAID 0 configuration (on the p88 model, four way on the p84) and capacities ranging from 256GB to 2TB. Oh, and transfer rates up to 1.4GB/s (950MB/s sustained write), not too shabby at all. No official pricing is currently available, but expect it to be firmly in the enterprise only bracket, especially with those impressive performance figures being restricted to the 1TB and 2TB p88 models.
