For my personal use I would replace that Drive asap. - There is no warranty for it anymore (time since buy) - You can't buy it new anymore (discontinued) - There are more reliable drives available. I'd go for a Samsung Evo 850, that will give you five years of warranty. But, it's your drive, you make the decissions. - Yamaban.

He suggested you definitely reliable drive (Samsung). Reliable in my boot too. You ask his opinion about yet another Corsair. One by Corsair failed on you already. So, you should have better knowledge about Corsair's SSD reliability, right? Sorry to sound sour, it just amuses me how people keep buying things made by the same company whose products already failed on them. This is what creates the problem: keeps companies manufacturing bad hardware exist.

If you lose your data because of a failing disk you lose your data. Whether or not you get a replacement drive does not change that fact. The length of a warranty might be an indication of the expected life of a product, but it says nothing about the state of one individual drive.> - You can't buy it new anymore (discontinued)Again, relevance?> - There are more reliable drives available.Still no argument to replace an existing working one... And as I asked Valeri, can you please provide us with links indicating the poor quality of Corsair SSDs (in general)? I do not know how SSDs fail, but when regular HDs start to fail you usually have some time to get a replacement before they fail altogether. I would expect the number of reallocated sectors to increase, but still have a little time to replace the disk once that happens. And supposing the disk actually does store the number of "retired" blocks this disk seems fine:> > 5 Retired_Block_Count 0x0033 100 100 003 Pre-fail Always - 0Regards, Leonard. -- mount -t life -o ro /dev/dna /genetic/research
