Corsair Accelerator 30GB Caching SSD Review

The Corsair Accelerator 30GB drive is physically similar to most 2.5” SATA SSD drives, with only minor aesthetic improvements. The chassis is entirely black with rounded edges and a large sticker covers most of the drive’s top side. Tipping the scales at less than 75gr, the device is frighteningly lightweight, even for a SSD drive.

The bottom of the drive is almost entirely bare, with the exception of two stickers. One of the stickers has the Dataplex software serial number printed on it, while the other is a small oval warranty sticker placed at one of the drive’s corners.

The user needs to make sure that the Dataplex software series is written down inside the manual or any other secure place prior to installing the drive. Be warned that the Dataplex software recognizes hardware changes of more than 2 parts as a different system; the user needs to uninstall and reinstall the software prior to major hardware upgrades or will have to contact Corsair Support to unblock the serial.

After cracking open the Accelerator, the cause behind its very little weight became obvious. The PCB housing every component of the drive is barely half as large as the actual chassis, which could have been well smaller if not restricted by 2.5” disk drive size standards.

Much like with the 60GB version of the drive, Corsair went with a Sandforce SF-2181 controller for their cheapest caching SSD. The Sandforce SF-2181 is a SATA-II compliant chip, essentially limiting the drive’s maximum read and write speeds at about 280MB/s. However, the Corsair Accelerator is using no over-provisioning at all, meaning that the 30GB of the drive are all available for data hot-caching.

The NAND flash memory chips of the drive are supplied by Micron. The Micron 29F64G08CBAAA-A used in the Accelerator are asynchronous-type memory chips, commonly found inside middle-range and value drives.
