Hmm, so what about these modern high density hard drives which store track parameters for their servos in on-board flash (aka OptiNAND)? Do we get "spinning rust" which might loose the information where exactly it stored the data?

- binaryturtle 11mo agoI wonder too. I don't trust SSDs/ flash for my archives, hence I'm stuck on max. 18TB drives atm.
- markhahn 11mo agoshouldn't really be a problem, since the capacity required for this use is so low. the real issue here is QLC in which the flash cell's margins are being squeezed enthusiastically...
- userbinator 11mo agoI think you're talking about two different things; "adaptives" are usually stored in EEPROM or the MCU's NOR flash, which is basically better-than-SLC levels of reliability, especially as they're written once and treated as ROM after that. OptiNAND is a "SSHD" and thus has the same concerns with retention as an SSD. https://en.wikipedia.org/wiki/Hybrid_drive https://en.wikipedia.org/wiki/Hybrid_drive
