Product Information

M.2 drive length isn't always an indicator of drive capacity, but therearelimits to NAND-chip density and how many memory modules engineers can stuff onto a PCB of a given size. As a result, most of the M.2 drives we've seen to date have topped out at 2TB, though you can find a few 4TB and 8TB models at lofty prices. The typical capacity waypoints are as follows: However, from an engineering point of view, SSDs didn't needto be that big. The enclosure an SSD comes in has a lot of dead space inside. It's designed in that 2.5-inch size and shape to make the drive fit into those existing bays. So when mobile-device designers, challenged with slimming down laptops and tablets, reassessed this issue, the consensus was clear: The bulky 2.5-inch form factor, eventually, would have to go. Anyways...having only one capacity option is what stops it from being a tempting buy. Half of the market isn't even focused on having 4TB name...even Samsung hasn't bothered with it.

But first, the shape issue. Any M.2 drive you are looking at will be labeled with a four- or five-digit number as part of its specifications or model name. It's a measurement, in millimeters: The first two numbers define the drive's width, the second two the length.Tomshardware, I can't find any latency measurements per read operation out there! As in you give the SSD a 4K aligned read command, how many milliseconds will it take for it to respond. The way they want to sell them at a higher per TB cost than low TB drives runs against consumer's understanding of the world.

This drive typically uses the Phison E12S controller with 96-layer or newer QLC flash, as well as DRAM for metadata caching. What is the TBW rating for this SKU?If you're leaning towards a budget build, you might want to consider buying Solidigm's P41 Plus or even Samsung 970 EVO Plus. Both drives have similar performance and will do very well thanks to their still good random performance, but the P41 Plus is much more efficient and will be much more suitable for laptops. The Phison E18 SSD controller has proven to be quite the contender even when burdened by 64 dies. This one seems to have been manufactured during the 28th week of 2021. It’s likely the firmware has been optimized for this NAND as well as for managing that many dies. One last caveat to drop in before we get to our product recommendations surrounds Intel's SSD line. Intel for a while sold a family of M.2-based storage products under the brand name Optane, in two very distinct types of drive. Intel'sOptane SSDsare SSDs like any other, bootable drives that can serve as a stand-alone boot drive or as secondary storage. They were discontinued for consumers in 2021, but you may still see them around. (Incidentally, Intel ultimately sold its SSD business at the end of 2021 to SK Hynix, which has spun it off into a new Hynix subsidiary, Solidigm.)
