| Plextor’s M6 Series SSDs at CES I stopped by Plextor at CES last week for the announcement of their latest SSDs, from their upcoming M6 series. These drives are slated to (eventually) replace the current generation M5 Pro, M5S, and M5M SSDs with slightly faster hardware based on new silicon and with new interfaces. Starting at the bottom in terms of performance and presumably cost, Plextor has their new M5S in 128GB/256GB/512GB capacities. It uses custom firmware with Marvell’s 88SS9188 controller and delivers peak transfer rates of up to 520MBps/440MBps read/write on the 512GB model, with the 256GB and 128GB versions dropping max write speeds to 420MBps and 300MBps, respectively. Max read/write IOPS are rated at 94K/80K for the 512GB drive, 90K/80K for the 256GB model, and 88K/75K for the 128GB drive. Availability for all of the drives is scheduled for Spring 2014. Next up is the M6 Pro, also in capacities of 128GB/256GB/512GB, using the Marvell 88SS9187 controller, which increases maximum performance moderately over the M6S. The 128GB drive is rated at up to 96K/81K IOPS and 545/330MBps read/write performance and comes with 256MB DRAM cache. The 256GB model increases the DRAM cache size to 512MB and boosts read/write performance to 545/455MBps, with 101K/86K IOPS. And at the top of the product stack the 512GB drive has 768MB DRAM cache with read/write speeds of 540/460MBps and 101K/88K IOPS. If we look at the existing M5 Pro drives, we’re basically seeing the limits of the SATA 6Gbps interface, as throughput isn’t really much higher and IOPS is only about 4K-10K higher at best. Still, the Plextor SSDs have performed well and updated models will be welcome. http://www.anandtech.com/show/7691/p...es-ssds-at-ces |
