SSD's lose data?

Unfortunately it wasn't the daily mail... it was someone who pretends to actually know / works for a security company.

Fortunately he ends the blog article with the conclusion that for long-term backup purposes you need mechanical drives... which is not correct as they're only designed to retain data for a few years... So I feel happy mostly ignoring this article.

There is a reason the backup industry is still focused on Tape which has a intended retention of 30 years.
 
Some of the new drives are coming out with a warranty of 5 years or 150 terabytes written.

Put in perspective, that's about 80gb per day for the entire 5 years. That's really quite hard to do; my own hiberfil.sys is about 25gb (32gb ram, no idea why the file is smaller) and gets written twice per day. That's 30 gig to play with - which is surprisingly large if you're not into video editing.

Not to mention the strong probability that you won't want the drive to last 5 years anyway :)
 
That is from an endurance perspective, which is a different thing to what the korelogic blog raises.

It is a known thing flash cells may loose charge over time (It's the underlying problem in 840 EVOs) but the blog doesn't do any references why enterprise drives should loose data much faster... so heavy grain of salt is in order
 
Ah, my apologies. I'm so used to the endurance question that I tend to answer it without probing too deeply ^^;

With regard to heat-related data loss however, presumably it's not a thing for an actively used PC or we'd have had a massive public outcry by now? If your PC lost its data every time you went on holiday, people would have noticed... seems like the article is covering a very specific scenario that most people don't do.

That said... I do have a software backup service constantly mirroring writes to my important folders to a NAS box. This however is something I set up before SSDs were invented, and I maintain that it's still something that every single person with a computer should do :)
 
All drives can and might lose data at sometime given enough time and other factors but SSD's are no more unreliable than normal mech drives.
 
The only way of ensuring your backups are valid is to either test them regularly, or refresh them. Tape technically speaking has a long shelf life, but many environmental factors come into it, and if 5-10 years from now you can't get a tape drive to work, it doesn't matter how many tapes you have, you've lost access to your data.
 
never heard of this or come across it but then I never leave my PC off for long periods of time nor do I have any spare SSDs just laying about with data on not being used.

maybe someone has a external SSD that OCUK sell that isn't used very often?
 
Odd, i have moved data out of 2 128gb backup SSDs in USB caddies that were put down since i had my 920 D0, circa 3-4 years ago and both were fine, exact same files and both matched byte for byte.
 
Looking at the article is only when the temperature goes over 25c? So in the UK they are immortal.
 
Totally irrelevant for most users.

They will almost certainly reach these temperatures in a computer.

But for YEARS without power at those temperatures?

Another reason to not live in the middle east.
