We all know that an SSD will be more reliable than a typical HDD due to it having no moving parts. But something must stop and SSD working? Will performance decline over time? When would you expect to need to buy a new one after initial purchase? They are expensive items, just trying to judge if they are a sound investment yet.

The cheaper ones can be killed rather quickly if you were to run something like spinrite or anything that will write a ton of data to the drive. cheap SSD's may be more in the 10TB+ range of data written to them.

the current top of the line SSD's from intel are advertised by intel to handle 35TB of data written to it before it fails. Intel claims this is enough for you to write 20GB of data a day for 5 years but then again you are talking about $300-500 SSD's

Intel did not provide info on the lifespan on their lower cost SSD's but you can expect it to be significantly less.

SSD is so new in the market that while there are published research, it is currently all theoretical reasonings.

Anandtech's Review of the Intel-X25M

Although here is some information, there are many others online, you can google search and find out more. However, the list of all articles is SSDs are more reliable than hard disks, and should last a good 20 years at least not counting performance degradation.

I not too sure but as long as you dont do anything stubid then it shold last somthing like 100 years. Im sure i have read somthing saying that they will last longer that.

That is ofcoure skynet is never mad and we are never forced to set off an EMP to save our lives.

Scary stuff.

The thing about hard disk failure is most of the time a hard disk fails gradually. Sudden, unexpected, catastrophic unrecoverable failure of a hard disk is not all that common. Usually what happens is you have some errors over time giving you some hints maybe you should replace it.

But SSDs, I don't think they have gradual failures. I think they just suddenly die. And if you're talking about thumb drives, well, they have to withstand repeated USB insertions. I don't know about you but I've had the usb connector on thumb drives fail at the solder point. You can't easily fix that, so I just pitch the whole thing. To me, thumb drives are as expendable as floppies.

Another time I had a USB thumb drive that was 64gb (supposedly) and was formatted using either FAT16 or FAT32 (I don't remember which). I attempted to format it using NTFS (I don't remember why, exactly, but apparently I discovered they dont support NTFS) and this caused the drive to fail. I was unable to reformat it or mount it on any of my PCs at the time. I ended up taking it to a Mac running OS X which was able to reformat it to a usable version of FAT32. It's still not the most reliable drive in the world, I think I was ripped off.

Maybe if I had a SSD RAID system with like three SSDs running, that might be reliable enough to consider. But at this time I'm not convinced they are worth the trouble, considering how reliable hard disk technology has become.
