The move to TLC NAND flash memory has been expected for some time but a new trend seems to be showing itself at Computex this year that is definitely unexpected, this being the move away from LSI SandForce over to Marvell. Three manufacturers specifically (Memoright, SanDisk, BIWIN) have spoken to us about this and when asked why they might be doing so, all related that they needed better control of firmware development for their own engineering expertise.
For Memoright, this is shown in their XTM Series of SATA 3 SSDs where they are relying on, not only the Marvell 88SS9187 controller, but also, Toshiba 19nm NAND flash memory. The XTM is available in 128, 256 and 512GB capacities and has performance up to 540MB/s read and 480MB/s write with up to 90,000 IOPS at low 4k random read disk access.
Also new to Memoright is their move to TLC NAND memory and they have done this with their newly developed XT3 TLC SSD. The XT3 is based on 1Xnm MLC memory, capable of 540MB/s read and 300MB/s write performance and relies on Memoright’s own firmware design once again which speaks to the Plextor controller once again.
Let’s finish our memoright tour with a walk-around of a few of their other products. A quick click on these photos, or any of our shots at TSSDR, will bring up a higher resolution image:
