SSD manufacturers quickly discovered that drives they sell are too good and last too long. So now we have TLC-based and QLC-based drives for almost all market segments, which sold for almost the same price as MLC-based drives were sold in the past. Ex. Kingston HyperX FURY [SHFS37A/120G] was produced in 2014 and was MLC(2bit)-based. It had 3 year warranty and was rated for 354 TBW or 2,69 DWPD. HyperX Fury RGB [SHFR200/240G] (2019) is now 3D TLC(3bit)-based. It has same 3 year limited warranty and advertised as 120 TBW or 0,46 DWPD. Worst offender of this "modern SSD fraud" is Samsung, because he still says 3D-NAND-V-whatever MLC in advertisements when in fact those drives are TLC, because TLC NAND is 3bit per cell. Only recently, Samsung began to add (3bit) to that "3D V-NAND MLC" phrasing in specifications. Other manufacturers parroting the same marketing trick and getting away with it. And as a result, MLC-based drives almost vanished from consumer\enthusiast markets because people are happy with TLC and know no better. -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄⠀⠀⠀⠀ |
