1TB Samsung 970 EVO Plus M.2 NVMe Internal Solid State Drive Expired

"Most SSDs on the market today use a DRAM cache to improve latency and bandwidth. However, due to the nature of DRAM chips, DRAM cannot store data when power is lost, which is a legitimate reliability concern for SSDs when unexpected power outages occur. Most consumer SSDs aren't equipped with the power loss capacitors that we see on enterprise SSDs, which makes them more vulnerable to losing data during unexpected power loss events.

The DRAM chip holds a lot of important data, not just temporary data that needs to be transferred to NAND storage. DRAM also holds the drive's FTL or Flash Transition Layer, which is used as a map to see where data is stored on the drive. If the FTL is corrupted, the entire SSD could also become corrupted.

Thankfully, some SSD manufacturers have countermeasures in place for such an occasion. One example is a technique used by Samsung that employs journaling to keep as much data intact as possible during a power outage. Journaling allows SSDs to keep track of what changes need to be made to the SSD from the OS's file system before they happen. When a power outage occurs and data is lost in the DRAM cache, the SSD knows what data was already transferred to the NAND (and what data was lost directly from the journal). "

"Russ Bishop, a programmer at Apple, noticed some interesting and rather worrying behavior from some NVMe SSDs when he tested the impact of a power outage on the cached data.

Out of the four SSDs that Bishop tested, two of them worked perfectly as they should, preventing data loss. These two models are:

Samsung 970 EVO Plus
WD Red SN700

The two other models that lost data are:

SK hynix Gold P31 2TB
Sabrent Rocket 512"

What's with the salt? A lot of people have notifications set up for M.2 deals specifically to get one for their PS5 like me. No one posted if it was compatible so I checked the Amazon reviews and saw it wasn't. Someone who wants on for the PS5 will see my post and save them the time having to check themselves.
