Plextor's M5M SSD is one-eighth the size of a standard 2.5-inch drive.
It's been a long, long time since Plextor's bread and butter was high-quality optical drives. It's perhaps a little bit ironic that Plextor's newest product is intended for Ultrabooks, a form factor that largely shuns optical drives (only a handful of Ultrabook models ship with a CD/DVD or Blu-ray drive). Plextor finds itself focused on solid state drives (SSDs) these days, and the company's new M5M mSATA Series drives are intended to give Ultrabook owners some upgrade options.
Announced today at the Consumer Electronics Show (CES) in Las Vegas, Plextor's M5M drives read data at up to 540MB/s through a SATA 6Gbps interface. The 64GB model writes data at up to 160MB/s, the 128GB at up to 320MB/s, and the 256GB at up to 430MB/s.
Plextor continues to tap Marvell to provide the controller chipset for its SSDs; in this case, it's the Marvell 88SS9187 working in combination with Plextor's True Speed technology designed to eliminate performance degradation over time.
Other features include 256-bit AES full-drive encryption, 128-bit error correction, and support for DEVSLP power mode to reduce power consumption and extend battery life on ultra portable devices.
