SSD Prices In A Free Fall

Haven't been using this drive that long, curious what numbers others may have

I don't think SSLife is worth much. It makes some sort of estimate based on the amount of writes you've done.

I had an 80 GB Intel SSD which SSDLife said had an estimated lifetime of 6 or 8 years for the first 2 or 3 years of ownership. It then inexplicably jumped to over 150 years remaining--late in the next century. My usage pattern had not changed. Did my drive suddenly get "healthier" or did the NAND change? I don't think so.

You can track the necessary, with greater detail, with other tools--such as Crystal Disk Mark portable version.

That's probably a normal amount of writes IF "work time" means hours powered on. I've written 617 GB in 1329 hours powered on---this is on a Crucial MX100 that I bought not quite 3 months ago. Roughly 1/2 GB per hour. You're about double that, which I doubt is significant.


But I don't know how you are using your drive or any details of your usage pattern.

You might want to calculate the WAF (write amplification factor). It's said to have a reasonable correlation to remaining life. You can do it from certain SMART data, if they are revealed to you. I've heard average WAF is maybe between 3 and 5. This Crucial of mine is sitting at 1.71, rising slowly--to what eventual level I don't know.

The formula is 1 plus (background program page count/host program page count), at least on a Crucial. And your SMART data would have to reveal those 2 parameters or their equivalents. I guess what's revealed in SMART depends on the SSD manufacturer.

It isn't the estimated life I was referring to, but rather the amount of data written

I don't see anything remarkable in the amount of data written to your drive.

If excessive, it could last a very long time rather than a very, very long time.

Or fail tomorrow for reasons unrelated to the amount of data written.

I'd probably try to resist any impulse to upgrade firmware, barring a strong and over-riding reason why you have to have the upgrade.

Again, I wasn't seeking if my data was remarkable, or anything else about it. I was just curious what numbers people would have that have been using their drives for a long time

Didn't those torture tests get into the petabyte region?

Yeah, the numbers were ridiculous, and that was constant use, not the low use most will actually get. I have reimaged my drive numerous times after experiments and such. Thus what I assume are higher then "normal" numbers on my drive. But I am not going to baby it, as it is apparent that they will last a long time barring any unexpected failures that can occur with any electronic device.

I am just curious what numbers some have on long used drives. A Guy

I keep the free version of SSDLife on my machines simply it's a quick and dirty way to check to see if TRIM is available and enabled and to get a general idea of the SSD's condition. It's worth far more than what I paid for it. It has limited use and gets used very infrequently but it's still useful.

Keep in mind the estimated life remaining is just that, an estimate. It's based on the volume of writes, the amount of time those writes occurred in and the estimated amount of writes available as provided by the manufacturer. The latter may explain the jump in expected life on your SSD. Some manufacturer's make conservative estimates on how long their SSDs will last; others, not so much. It's possible Intel upped their life expectancy estimate.

I much prefer Crystal Disk Info (portable). AS SSD will also allow you to easily check that alignment is ok.
Also, if you have more than one SSD installed SSDLife spits the dummy and says you need to buy the pro version.

I don't know the drop in "Health Status" to 94% is to be expected given the SSD usage.
