Reliability of SSD drives ?

"...
The standards body for the microelectronics industry has found that Solid State Drives (SSD) can start to lose their data and become corrupted if they are left without power for as little as a week. ... According to a recent presentation (PDF) by Seagate's Alvin Cox, who is also chairman of the Joint Electron Device Engineering Council (JEDEC), the period of time that data will be retained on an SSD is halved for every 5 degrees Celsius (9 degrees Fahrenheit) rise in temperature in the area where the SSD is stored.

I've left mine without power far longer than a week and not had a problem. I've never had a Samsung 840/850 PRO fail and had no reports of customers' SSDs failing either.

Mechanical drives I seem to have been unlucky with recently, a WD Green 4TB drive failed within a day and a blue failed a week after the warranty and I have seen lots of laptops (I used to repair them) with problems that have been due to drives failing - particularly Seagate. I stopped buying Seagate a few years ago when they dropped the warranty period from 5 years and I had several drives fail but may have been due to bad luck. I have had a 250GB Seagate laptop drive which was 4 years old when I put it in (from a relative's laptop), in my HTPC for over a year and it has been fine. Enterprise class drives should be much more reliable.

Whatever you use it is a good idea to have a couple of off site backups if you can.

Similar story here with Samsung, Toshiba, Intel and OCZ SSD's lying around for months and never had an issue when reconnected, so far I have never lost an SSD to failure but only a matter of time i guess.

I have had loads of spinning disc failures over the years with the worst being the old IBM drives which used glass coated discs, IBM Disc business was then bought out by Hitachi I think and as least back then I could RMA them directly to the Hitachi plant in Bray.

Gave up and went to Seagate HDD after a day in the manufacturing facility in the North and I was impressed by the whole manufacturing process, i think I had a failure on one several years back.
I have been buying WD HDD drives in recent years and so far I have not lost a Western Digital HDD.

Backups....backups.....backups, drives and more drives!!

Here is a link to an article on HD reliability - not ssd's though.

Looks like Hitachi are the most reliable and seagate the least.

If anything, a good reason to separately power your SSD and leave it on at all times.

Even though I do think that dire SSD prognostication has become a popular internet sport.
