SSD Write Endurance 25nm Vs 34nm

[Vapor]

For how long?
(most likely a side-effect of the nLTT FW, let's see what happens to mine)

Been a few days now, normally each MWI tick was ~2.5TiB and it's been stuck at 10 MWI for over 14TiB. SynbiosVyse's last update had 10 MWI when it could/should have been 9 (based on extrapolation). I would be very surprised if this were due to the nLTT setting, I think it's just a Sandforce oddity (like their first 3-5% expected lifetime being stuck at 100 MWI).

And now, like magic, they're back, but not at the same level.
I bet this smart attribute is really some kind of timer or something (who knows?).
I don't think it's anything like the label would imply.

I've noticed RRER jumping around on my 4 Sandforce drives, as well. Never thought much of it though--normalized threshold is at 50 and I don't think I've ever seen the normalized value worse than 85.

I wonder if there were some way to log it every minute-ish and see if potential drastic dips align with potential future crashes.


@Anvil and @Christopher, what kind of static data are you using? Your wear range deltas are already way past mine (3) and seem to be scaling like SynbiosVyse's (which is over 100, as of last update). SF-1200 and SF-2200 aren't exactly the same beast, but I would be surprised if wear leveling performance were reduced on the SF-2200 (unless it were for a tangible performance gain). The odd thing with my WRD vs. SynbiosVyse's is that he has just a few MB of static data whereas over 50% of my drive is filled with static data--one would expect wear leveling to be more effective on an empty drive.
