OCZ AEONDrive DRAM SSD Detailed
 

As a leading SSD vendor, OCZ sure has a strong engineering muscle to flex. Flex it did, with the AEONDrive DRAM SSD. This drive uses DRAM as its primary storage medium (as long as there's a constant power source). The device is thus ideal for those parts of the datacenter which hold "hot data". Unlike similar solutions such as FusionIO drives, the AEONDrive utilizes SAS 6 Gb/s interface. SAS is a low-overhead protocol since it allows exchange of larger numbers of simultaneous host commands than ATA. As for the performance OCZ claims the AEONDrive provides 140,000 IOPS 4K, and 540,000 IOPS 512. Since DRAM is a much lower-density medium than NAND flash, one should expect AEONDrives to be available only in relatively low capacities such as 64 GB (still big enough for pain databases). Not much more is detailed about the drive. It would be great if the AEONDrive could back itself up onto NAND flash before turning itself off.
