Re: How long will my (your) SSD last?

said by trparky:

Last update they posted indicates that they have written a total of 100 TBs to the drive and it's still chugging along. They will update the article with various milestone updates, the last milestone was 100 TB. They will continue to update the article until the SSD dies.

Well, already I feel GREAT. I will NEVER, EVER write near 100TB on my SSD. After 8340 power-on hours, I've read 4.4TB and written 896GB (I think ... koitsu ... is my ID 241/F1 and ID 242/F2 RAW DATA read as GB?).

According to CrystalDiskInfo, my SSD has been online for 693 hours and has written 556 GBs.

It depends on how the vendor chooses to implement storage of the SMART attribute data. For example, on some (not necessarily all) Intel SSDs, attributes 241 and 242 RAW_VALUE columns track the number of 32MBytes (more specifically 32MiBs) read/written. Use smartmontools, it has proper decoding for this. Proof:

So for the above SSD, 42034*32 = 1,345,088 MiBs have been written, and 4560*32 = 145,920 MiBs have been read.

Another example drive, different model, but still Intel:


(This model does not track reads)

109412*32 = 3,501,184 MiBs, which is correct (using Intel's SSD Toolbox, the humanised value shown is "3.34TB").

But as I said, it varies per model of drive and manufacturer of drive (both things).

TY. Then it looks like OCZ is correctly displaying the conversions. I compared the smartmontools output to what OCZ Toolbox and it works. Thx again. My fuzzy math sees 349days of 2.56GB writes daily and 12.65GB reads daily. It'll take me a minute or two to get to 100TB writes
