sTec s260 mSATA SSDs Announced

sTec, a WD company, has announced their latest SSD, the s260 in mSATA form factor. The sTec s260 will find its way into embedded applications and compute situations where space is at a premium. The s260 uses a SATA 6Gb/s interface and features a modest power draw of 1.5W. sTec not content to just float out "another mSATA SSD" has added power fail protection to protect in-flight data in the event of unplanned power loss. They've also included environmental specs that support extreme altitudes and temperatures; something that ruggedized computing gear often requires given the intended use cases. 

The s260 will ship in a variety of configurations using both SLC and eMLC NAND. The SLC drives come in capacities up to 64GB and offer read and write throughput of up to 500MB/s and 250MB/s respectively with endurance of 10x drives writes per day for 5 years. The eMLC drives are available in capacities up to 200GB and offer throughout of up to 500MB/s read and 150MB/s write, with support for 10x drive writes per day for 3 years.
