SSD Internal battery life?

[amdhunter]

And when I tried to start it up, I got a STOP error on bootup. I didn't write the STOP error down, but I am positive it was the SSD's fault -- I have another HDD in my case for "emergency bootups."

I booted off my emergency drive running XP, and pulled my data off fine, then scheduled a chkdsk -- it found problems on the drive (which I guess is common enough) but it didn't settle the issue.

Reinstalling Windows 7 worked flawlessly, but now I have to reconfigure everything again, but whatever. I've been OCCT'ing for about 20 hours now with no other issues, so I am kinda sure something went awry with the SSD while it had no power.

Has anyone noticed any strangeness when leaving the SSD powered off for extended periods of time? Or should I just consider this a fluke?

fluke.
SSDs also do not have an internal battery.

Those errors on the drive could be caused by your RAM. You should make sure it's not unstable (run memtest.)

NAND will remember its state for something like 10 years with no power.

Ah good to know. Thanks.

That was my very first thought. I've run a 20 Hour OCCT run and will run memtest overnight to make sure. I am insane when it comes to checking for stability.

the next x25-E (gen2) will have a battery backup as its really not a good idea in enterprise to well not have one

current x25-e does not have battery sadly.

Actually, 5 years is the spec. I would refresh the data in 3 years just to be safe.

Electronic leakage from flash cells tends to have a noticeable effect (after ECC) in 10 years or so. I need to dig up a reference though.

yeah, but that's because losing power during writes (cached stuff) before its flushed to disc is a HORRIBLE thing for enterprise. Not for data retention.

exactly, that battery would be because of cache.. where the OS sends something the drive will say "i wrote this" but it will actually be sitting in its own "ram" (cache) waiting to be written. if you lose power at that point the data is lost, and yet it was considered written (which is really bad for enterprise databases... and thats it, it has little to no effect on a home consumer).
