Phison has been sampling its entry-level PS5008-E8 NVMe SSD controller for nicely over a 12 months now, and numerous its companions have demonstrated their drives that includes the chip, however nobody has began to ship precise merchandise to this point. Because it seems, issues are about to alter as Lite-On has quietly added its new entry-level MU X PCIe x2 SSDs primarily based on Phison's controller to its lineup and guarantees to begin promoting them shortly. Apparently, Lite-On will promote the MU X merchandise in retail, which doesn’t occur typically with the model.

Lite-On’s MU X M.2-2280 SSDs might be accessible in 128 GB and 256 GB configurations concentrating on cheap gaming PCs that want one thing quicker than typical SATA SSDs, however can’t afford extra superior PCIe x4 drives. The Phison PS5008-E8 controller will work with Toshiba’s 256 Gb BiCS3 3D TLC NAND reminiscence, which is gaining traction amongst SSD makers today. Phison but has to reveal all the main points about its PS5008-E8, however what we do know is that the controller is compliant with the NVMe 1.2 specification, makes use of a PCIe x2 interface, options 4 NAND channels, a DDR3/DDR3L DRAM buffer, Phison’s proprietary error correction algorithm referred to as StrongECC, the corporate’s personal RAID ECC algorithm to get better consumer information from uncorrectable errors, AES-256 encryption, and so forth. The important thing promoting level of the PS5008-E8 is just not excessive efficiency, however affordability and reliability.

Certainly, the Lite-On MUX 256 GB gives as much as 1600 MB/s sequential learn pace in addition to as much as 850 MB/s sequential write pace (with pSLC enabled), which doesn’t seem to be a record-breaking efficiency, however which is according to up to date entry-level PCIe x4 SSDs. With regards to random efficiency, the MUX 256 GB is able to 140Okay/145Okay random learn/write IOPS, which is forward of many PCIe x4 drives. As for the 128 GB mannequin, its write pace is speced at as much as 1500 MB/s, however its learn pace is 450 MB/s, which is comparable with fashionable SATA SSDs. As for reliability, Lite-On charges its MU X drives for 1.5 million hours MTBF and covers them with a three-year guarantee.

Lite-On produces most of its drives for numerous PC and server OEMs, to deal with shopper markets, the corporate makes use of the Plextor model. OEM orientation of Lite-On’s SSD enterprise is a main cause why the corporate makes use of SSD controllers from a number of builders (together with Marvell, Silicon Movement, and Phison) — totally different shoppers have totally different necessities with regards to efficiency and pricing. A few of Lite-On’s drives use in-house design, different are primarily based on reference designs from respective builders of controllers. With regards to the MU X, the drive makes use of a design developed by Phison, which has handed Lite-On’s high quality checks.

Lite-On’s MU X drives will hit retailer cabinets within the coming weeks. MSRPs of the drives are at present unknown, however since affordability is a key function of the controller, count on the precise SSDs to be priced accordingly.
