In the past few months, the cost of solid state drives has dropped substantially, allowing more consumers the opportunity to enjoy the various advantages they hold over mechanical hard drives, namely lightning fast access times, transfer speeds that actually push the bandwidth of the older SATA standards, superb energy efficiency, and completely silent operation.

The bulk of consumer grade SSDs currently on the market are powered by LSI's SandForce controller, an affordable solution found in countless drives from various manufacturers like Intel, OCZ, Corsair, Kingston, Mushkin, and ADATA. The latter just released a new flagship SSD, the ADATA XPG SX910, powered by the current standard for budget SSDs, the venerable SandForce SF-2281 controller.

It's difficult to keep track of all the current SSD options available as the market is somewhat flooded. ADATA themselves have been selling several different SandForce models prior to this, with the last being the SX900, released only a couple of months ago. As you can guess from the model number, the SX910 is meant as a higher-end alternative The SX910 is a more premium product aimed at gamers and professionals who have higher performance demands than the average Joe.

Like the SX900, the SX910 is offered in slightly higher capacities than most SandForce drives (128GB instead of 120GB, 256GB instead of 240GB, etc.) All SSDs have more raw capacity than is usable with a most of the unseen space provisioned as backup storage for when NAND cells eventually start dying from overuse. Recently LSI has started allowing manufacturers to alter the firmware to change how this extra space could be utilized and ADATA has decided to maximize usable capacity, to the tune of 7%.

Though you would expect that this would equate to lower lifespan, the SX910's specified MTBF is a standard 1,000,000 hours (114 years) and the warranty has been confidently increased from three years to five. Performance is also a priority and ADATA specifically notes that the Flash chips used for this new model are more closely screened, resulting in a crop of a higher quality, faster ICs. For all these benefits, the SX910 will command the lofty price of US$190 and $380 for the 128GB and 256GB versions respectively.


Package contents.

The 128GB model comes in a fairly standard package. Along with the drive, a short manual is included as well as a simple metal 3.5 inch to 2.5 inch adapter.


Underside.

For users who are upgrading existing systems, the drive also includes a key for a copy of Acronis True Image, to migrate your data safely without reinstall.
