Western Digital Readies WD Black SN850X SSD
Western Digital is preparing to update its client SSD lineup with a new flagship product, the WD Black SN850X. The drive was referenced in a December 10 certification filing with the PCI-SIG. The drive unsurprisingly features a PCI-Express 4.0 x4 interface. Nothing else is known about the drive, but the "X" in its name could signify a performance uplift over the current WD Black SN850 from an updated controller, a newer generation of NAND flash, or better stock cooling. Interestingly, the listing also references a drive called "SN820," which could be an "unbranded" successor to the PC SN810, a drive the company sells to system integrators and OEMs.

The weirdest thing they have right now is the PCIe 3.0 SN750 and the PCIe 4.0 SN750 SE, where the SE has slightly faster sequential read speeds and write IOPS, but much slower sequential write speeds and lower read IOPS...
