Real life experience on SSD life spans



@ TL7

In the past some controllers die very quick, especially in OCZ-SSDs. OCZ overclocked some controllers for higher IOPs.

Bur my Vertex 3 Max IOPs still works flawless, also my Petrol and Octane which are known for high failure rates


I have also 2 M500, 240GB. The Raw Read Error Rate should be 0, but increases and decreases sometimes. This is overall not a good sign.

To bad that many SSD-manufacturers don´t support this parameter


Well SMART is one way to monitor your drive, also most manufacturers have tools to monitor the drives health, samsung has magician, crucial has the storage executive.

Once again, all drives can fail without showing any warning.


My M500 works just fine, and raw read error is zero.


On your screenie I read 116?


Increases, then decreases?
How does that work?

Today it happened? No warning sign?

I wonder how that happened.


Nothing happened today, everything is working fine.


You are right, lets see if this will go up.


Dunno exact why this decrease, maybe it would be resetted at off/on and/or restart?

Decrease happens when the SSD is powered on and you read (a lot of) data

Have the same problem with some other SSDs, esspecially with my Corsair Neutron. This SSD sometimes slow down and the value increases

My exotic Mach Extreme hold the value, mostly it changes between 7 and 8

But most SSD-manufacturer don´t support this parameter


All of the better brands nowadays come with 5 year warranties and for reasonable prices.

I got my first SSD in May 2015 (warrantied til May 2020) which is a Samsung 850 EVO 250GB and it’s in my main PC and still going strong. Samsung Magician says I have written 11.8TB at the moment (most of my larger data writing is done on regular hard drives. so if I did not have those the data written to that 850 EVO would be noticeably higher. still, it does have some larger file writes to it here and there) and here it is 3 years and 2 months later and the drive is rated at 75TB written. so at my current rate ill get 20 years or so out of it (which I expect my computer to be outdated before it dies from written data to it). but it will likely go well beyond that 75TB written figure before failure actually occurs from writes. my guess is failure will occur from some other random thing before it will die from me writing data to it. but I guess we will all have to wait and see how reliable modern SSD’s are.

also, I just ordered a Intel 545s 128GB SSD earlier (about 4 hours ago) as it was a deal too good to pass up for such a quality drive and it also has a 5 year warranty. I got it for $31.99 (I doubt it can be beat for that price range as not long ago I seen a PNY 120GB SSD for $29.99 but only has a 3 year warranty and is generally a worse SSD than the Intel and I get a 5 year warranty and 8GB more storage space for only a $2 difference) as it will be a solid upgrade to my 10 year old laptop and it’s rated write life according to Intel’s site is 72TB of which I expect will go well beyond that to before actual drive failure occurs from writes (the 256GB model has 144TB written rated life span) which means I can just use it and forget about it, especially for only $32 as even if I did manage to wear it out from writes, it’s going to be difficult to complain for only $32.

basically just about any respectable brand modern SSD should easily last years unless your going crazy with data written to them or you happen to get a bad one in the batch.

NOTE: my Samsung 850 EV0 250GB is powered on 24/7 basically outside of an occasional reboot or power down to clean out the PC etc.


For normal consumer use? It should last years, maybe even decades.

Samsung just released their new 860 EVO and PRO line at the beginning of this year and they have a high lifespan, higher than their 850 line. They are Made in Korea too.


But fails are always pssoible.

I have many SSDs in my PCs and Laptops and had one total failure, and it was the most expensive SSD I ever bought. Some others made problems like slowing down sometimes or decrease the Raw Read Error. Some had single defect blocks, one have a lot of defect blocks in the first 10 POH.

On my work I had one failure of a SSD, it was dead as I start the PC. It was a half year old and don´t show any issues before it fails.

An other one have a strange behaviour, sometimes an software-installation or windows-update hangs and the HDD-LED lights permanent. Tried it in 3 different PCs, all show the same behaviour

If I compare with the many HDDs I had/have the SSDs are more reliable. But backup your data is necessary, even if you buy a Pro-SSD with 10 year warranty.

The bad things for me are:

  1. If you erase accidently data you can´t recover it like with HDD
  2. SSD die mostly without warning


In my opinion they are not worth the extra cost because your standard brand name SSD comes with a 5 year warranty and chances are if it reaches 5 years of regular use it will likely last many years beyond that. but even if the standard SSD’s don’t last much beyond 5 years your still better off saving the $ (by getting standard over pro) and putting it towards whatever is new say 6 years from now(assuming the standard 5 year warranty drives died around 6 years) as the money you save from buying a PRO currently will likely be enough to buy the same capacity drive, if not larger, in 6 years or so from now and things will probably have even better life span to and might even be faster to.

like currently looking online real quick… a Samsung 860 EVO vs Pro with the 500GB range of SSD’s (which are the largest SSD’s most people would buy currently as they are the sweet spot for most people), there about a $80 difference, so it’s far better to save the $80 (by getting the EVO) and in 5+ years of time, if the EVO SSD happens to die, you can likely get the same or better than what’s available now for that $80 or so that you saved by not getting the Pro and not only that it seems likely you will get more than 10 years, between the two SSD’s, should the initial one happen to die not long after the warranty expires as it seems like the odds are in your favor to get a fair amount of life over the warranty period especially between two name brand SSD’s. plus, like i was saying above… in 6 years or so of time from now I would imagine SSD’s life spans will be even better and likely faster to even though I realize that there is not much room for improvement for SSD’s on the SATA interface since they seem to be roughly topping out the SATA III interface. so who knows how much longer SATA will hang around but I suspect it should still be pretty common in 5+ years for desktop computers.

so basically… it makes little to no sense to get the Pro over the EVO for the vast majority of people given the info I just mentioned.

but that aside, what you experienced seemed to be what I have generally heard with SSD’s which is why I tend to prefer regular hard drives for storing more important data (and, as you already know, you get a lot more storage space for less $ with a regular hard drive over a SSD) and use SSD’s where speed is of higher importance.


The PRO’s have higher endurance ratings and uses MLC instead of TLC, but their price is like x2 that of the EVO.


For more than 99% of consumers Pro-SSDs also not better in speed at daily life, but more than 1% buy it :wink:



people don’t really think things through and just buy it as they probably see a 10 year warranty and think it’s amazing, and while it is a good product, it’s not worth the premium price over standard given all of that crap I mentioned above etc.

Yeah, but overall there is not enough of a difference to justify the price gap, especially for a high percentage of users.


I just had a 3-year old SanDisk Extreme 480GB SSD (SandForce 2281 based) stop working, which was a secondary drive in my laptop, i.e. no longer detected by the BIOS. I tried reseating it and also tried connecting it externally with a USB to SATA adapter. Its status LED just flashed red/blue in a loop and it was not detected by Windows.

Having just thought back to the OCZ SSD tapping trick, I banged the SanDisk SSD against the top of my knee a few times, popped it back on the SATA adapter and sure enough, it also sprung back to life. :grin:

So far the OCZ SSD hasn’t given any further issue since tapping it back to life, however, it’s used in a backup PC, so nothing to lose if it does cut out again.
