OCZ RevoDrive X2 240GB & RevoDrive 3 X2 480GB PCI-E SSD Review
OCZ supplies the RevoDrive X2 inside a relatively simple but well designed cardboard box. The artistic theme on the box is dark and relatively simple, with the series logo being the main attraction.
Inside the box the user will find the drive well packed and secured inside a second, hard cardboard box, wrapped inside an antistatic bag and surrounded by an ample amount of Polystyrene foam. Given the drive’s weight and size, it would be next to impossible for anyone to cause any damage during shipping.
Few items can be found bundled with the RevoDrive X2, namely just a very simple manual and a large case sticker.
Despite the numerous (64) MLC flash memory chips, the RevoDrive X2 is roughly the size of an average graphics card. OCZ achieved that by sandwiching two PCBs together; an easy and effective solution, especially since the RevoDrive generates virtually no heat at all.
The RevoDrive X2 is essentially four SSD drives bonded together with the use of a RAID chipset. The RAID chip the RevoDrive utilizes is a Silicon Image Sil3124 “Steel Vine” controller for that purpose. A Pericom PI7C9X130 bridge chip is responsible for the PCI-E 4x interface link and communication. The unfortunate detail of this configuration is that the RevoDrive X2 does not support several options, the most important being the TRIM command and wear monitoring.
SSDs require the use of a controller and four Sandforce SF-1222 joined together by the RAID controller were OCZ’s choice for their RevoDrive X2 SSD.
64 MLC flash memory chips form the four 64GB SSD partitions on the RevoDrive X2 240GB drive. The chips are supplied by Intel, part # 29F32G08AAMDB, and they are asynchronous type, consumer grade 34nm memory.
A minor but yet interesting addition, at the top left corner of the PCB OCZ installed 9 diagnostic LEDs for troubleshooting.
