SSD Lifespan?

[ycp]

I was looking to purchase some used 3.84TB Samsung PM1633 ssd's. The date of manufacture on them is July 2016 so 7 years old currently.
There is very little data written on them. In terms of Endurance there is plenty of more data that can be written.
But since they are over 7 years old, How long do you think they can still last on read heavy workloads?

What are their power on hours?
Anything else standing out from SMART?

 

[ycp]

I dont have the power on hours yet, and the seller says they are in very good health.
So i doubt there be any other problems.
I am just wondering assuming the drives are in very good health what is a reasonable time i can hope that they will last.

 

[rtech]

They should last unless there is some firmware problem.
I would want SMART and then make the puchase.

Age is not the biggest problem for SSDs
My boot disks were made in 2012
Put them in RAID 1 array and setup a regular scrub + setup send SMART data via email and youre done.

If you dont mind losing data or you cant put two disks in device. Ignore the sentence with RAID

I'm still trying to kill my iodrive2s with writes

Good luck =)

As for hours, I have some intel S3500s here with 70k hours on them so far hosting an SSD-backed share and such in my FreeNAS...

At work we have dozens of 160GB X25-M G2 drives running (non-production) databases with 90k hours and ~100TiB lifetime writes, a few especially old ones are more like 105K hours and 150TiB. Of course they lack PLP, so no capacitors to age, and they're kept nice and cool, should get a few more years of "no we don't have the budget to replace those machines" running out of them.

Wow @nexox I thought the Intel 330s I have floating around (testing\etc only) were old but X25


Other old drives that keep on kicking are the HGST SLC drives (and MLC).

I actually have retired 10k and 15k RPM drives with more hours (80k+) than most SSDs as SSD were replaced wtih newer\faster sooner than spinners


If your servers run 24\7 and you have minimal power events or restarts would the capacitors in side actually age as there's not much changing \ usage other than staying charged constantly ???

 

[nexox]

Some kinds of capacitors will lose capacitance just sitting for long periods of time, generally much faster at higher temperatures, and most of the SSDs I have used don't actually implement any PLP tests, so it's hard to tell when the capacitors have degraded too far to work.

At least we have (I think) retired all of our X25-M G1 drives, wish I could say the same about 15 year old, 500GB consumer-grade SATA HDDs.

Those SLC drives are neigh-invulnerable!

That would be the X25-E, the X25-M is MLC, but we have lots of them to spread out the writes (on the other hand, since they lack PLP the write amplification can get a bit high with constant fsyncs.)

So, i am coming to the conclusion that the PM1633 from 2016 should still be able to give me another 5 years or so of life.

It sort of depends on the temperature they experienced over their lifetime, but I just found a PDF indicating they use tantalum capacitors for PLP, which generally do not degrade over time, so I think you should be good with those for a few years.

yes... I have HGST HUSML drives on my desk with perm marker when i tested them.... (SAS2) in 2015 myself meaning these must be from 2011 or 2012. still work fine amazing how long these old tanks last.
