Samsung Is the Latest SSD Manufacturer Caught Cheating Its Customers
The other beats of this story are familiar. Computerbase.de reports on a YouTube Channel, which compared two different versions of the Samsung 970 Plus. Both drives are labeled with the same sticker declaring them to be a 970EVO Plus, but the part numbers are different. One drive is labeled the MZVLB1T0HBLR (older, good) and one is the MZVL21T0HBLU (newer, inferior). Peel the sticker back, and the chips underneath are rather different. The Phoenix drive (top) is older than the Elpis drive on the bottom. Computerbase claims a production date of April 2021 for the Phoenix, but if the 2110 and 2123 codes are production dates, this would seem to indicate March and June. It's possible that Samsung uses specific numerical codes for each month. Either way, the Phoenix drive is older and faster and the Elpis drive is newer and slower.
And -- just as we've seen from Crucial and Western Digital -- performance in some benchmarks after the swap is just fine, while other benchmarks crater. [...] The original 970 Plus starts with solid performance and holds it for the entire 200GB test. The right-hand SSD is even faster than the OG 970 Plus until we hit the 120GB mark, at which point performance drops to 50 percent of what it was. Real-world file copies also bear this out, with one drive holding 1.58GB/s and one at 830MB/s. TLC hasn't been swapped for QLC, but the 50 percent performance hit in some tests is as bad as what we see when it has been.
