Shortage of NAND Flash controllers

The analyst firm TrendForce has warned that solid-state drives (SSD) prices are going to increase this year.

Non-PRO version with 3D TLC V-NAND

While Samsung 980 Pro SSD is aimed at those looking to pull performance from the PCIe 4.0 interface, it appears that Samsung is working on a 980 non-PRO version which will use PCIe 3.0 interface, lack a DRAM cache, and be based on Samsung's latest 136-layer TLC V-NAND.

Writing too much

Twitter and the MacRumors forums are full of users reporting that M1 Macs are experiencing extremely high drive writes over a short space of time.

Coming in 240GB, 480GB, and 960GB capacities

Western Digital has released its new and affordable WD Green SN350 SSDs, which will be available in capacities ranging from 240GB to 960GB and come in a standard M.2 2280 form factor, with PCIe 3.0 interface.

Already out of stock

Samsung's 980 Pro has only lately become available in 2TB capacity option, and while it is listed on Amazon.com, it is currently out of stock, showing just how popular this M.2 PCIe 4.0 NVMe drive actually is.

3D TLC NAND with Phison E18 controller

A spotted listing over at Amazon.de revealed a new PCIe 4.0 M.2 SSD from Corsair, the MP600 Pro, which should hit read sequential speeds of up to 7,000MB/s.

Updated controller and TLC NAND for 560/530 MB/s read and write

Samsung has launched its latest addition to the SSD lineup, the 870 EVO, which pairs up TLC NAND with an updated controller in order to push the SATA interface to its limits, achieving 560MB/s read and 530MB/s write sequential performance.

Writing at up to 6,900MB/s

At its special MSI Premiere 2021 - Tech For The Future event at CES 2021, MSI produced a rather pleasant surprise, unveiling its first PCIe 4.0 NVMe SSD.

The fastest SSD coming in a 4TB version soon

While Sabrent's Rocket 4 Plus has been selling for quite some time, it was limited to 1TB and 2TB capacities, but, according to Sabrent, the 4TB version is coming soon as well.

Up to 7,400/6,800 MB/s of sequential performance

Silicon Motion announced three new PCIe 4.0 NVMe SSD controllers, including the high-end 12nm SM2264 controller, capable of hitting 7.400MB/s and 6.800MB/s sequential read and write performance.
