Transcend has released a number of new SSDs, some of which are in the M.2 format, along with others in the mSATA format.
The MSA340 is an mSATA SSD, with a SATA3 interface. The unit measures 51 x 30 mm and is 4 mm thick. Read speeds are set at 520 MB/s while the unit can write at 280 MB/s. It is built using MLC flash.
The N8S750 SSD is SATA3-based M.2 SSD. It measures 80 x 22 mm and is 3.5 mm thick. Aboard users will find MLC flash along with DDR3 DRAM cache. The drive can write at speeds of up to 330 MB/s, though it can read even faster at 520 MB/s.
Both of the units also support SATA DevSleep, allowing the drives to go into low power states when not in use, but wake up very quickly when needed. Desktops might not benefit much, but for mobile devices DevSleep is particularly interesting due to the power savings, allowing for longer battery life.
The mSATA MS340 will come in capacities ranging from 32 GB to 256 GB, while the M.2 N8S750 will have capacities ranging from 32 GB to 128 GB.
