SSD Failures???

[dmaksimov]

I was wondering if SSD ever fail? If they do, are there any tools to check if they have any defects? I searched up on google but couldn't find anything...
Thanks

I think they still have the S.M.A.R.T feature that alerts you when the drives failing...i could be wrong though.

Id immagine the fail rate on SSD drives will be low,i mean afterall theres no moving parts anymore like a standard hard drives.

Same as hard drives - buy a good brand if you want it to last. The newer models also are better as well and soon (if not now) ssd's from the same brand will be MUCH more reliable since no moving parts.

Flash memory has a fairly low number of read/write cycles, something like 10,000. That could be a big problem for solid state drives which use the same memory addresses repeatedly for routine operations. A technology called "wear leveling" ensures that read/write cycles are spread around the drive, extending the life of the array as a whole.

Most modern SSD's have a rated life of 1,000,000 - 1,500,000 hours, so chances are the SSD will last longer then you will ever need it to.

I'm sure you're right, but the drive as a whole can have a different rating than the individual memory elements. I'm sure that the best rated drives employ the wear-leveling technology. As each memory element fails, it reduces the capacity of the drive and the possibility of lost data. A person is well advised to check these ratings before investing in a SSD to replace a conventional hard disk drive.

The middle to high end drives also have a swap section so if a particular array fails over time, even with wear-leveling in place, the drive will disable the bad sector and swap in (assumedly re-addressing) the extra capacity into the mix.
ex. you buy a 100 GB SSD. it may have 110 GBs capacity with the additional 10 percent "locked" until the drive sees it necessary to swap all or some of it in to your use.
