SanDisk X300s is company's first self-encrypting SSD

The new solid-state drive uses AES 256-bit hardware-based encryption and comes in 2.5-inch and M.2 form factors.


SanDisk is working hard to earn the trust of enterprises with its solid-state drives. Last week, the company introduced its new Optimus MAX 4TB SAS drives for datacenters, and now it's rolling out new SSDs that are SanDisk's first to be self-encrypting. (In comparison, Toshiba started offering self-encrypting SSDs last year , and Samsung began way back in 2009.)

Dubbed the X300s, the new drive features AES 256-bit hardware-based encryption and supports both TCG Opal 2.0 and Microsoft Encrypted Hard Drive security technologies. It will also soon include the SanDisk SSD Dashboard, a software suite that offers Wave System’s EMBASSY Security Center (ESC), which can oversee which users can access encrypted data.

The X300s ships in two different form factors: a 2.5-inch version that can be installed in desktops and most laptops, and an M.2 version for Ultrabooks and other super-slim notebooks. Capacities consist of 64GB, 128GB, 256GB, 512GB, and 1TB, though the M.2 drive maxes out at 512GB. SanDisk promises sequential read speeds of 520MB/s and write speeds of 460MB/s.

Of interest to road warriors, SanDisk has attempted to minimize the power consumption of the X300s, as its SATA DEVSLP low-power mode is compatible with Microsoft's Windows 8 InstantGo to limit power draw while the drive is idling. Mean Time to Failure (MTTF) is estimated at 2 million hours, with the X300s able to handle roughly 43GB of daily writes over a five-year span.

Potential enterprise customers will be able to obtain the X300s SSDs starting next month through the SanDisk Commercial Business Channel.
