Ono sto Google ing-ovi tvrde potpuno relativizira sve uobicajene prakse (koje cu i dalje provoditi, barem iz navike) i radnje kojima se trudimo osigurati toj limariji sto bolje uvjete za rad.

Ona Googleova analiza je potpuno neprihvatljiva iz jedne jedine stvari, a to je upotreba consumer diskova za serverske svrhe.

It ain't smart to rely on SMART

Google studied a hundred thousand SATA and PATA drives with between 80 and 400GB storage and 5400 to 7200rpm, and while unfortunately they didn't call out specific brands or models that had high failure rates, they did find a few interesting patterns in failing hard drives. One of those we thought was most intriguing was that drives often needed replacement for issues that SMART drive status polling didn't or couldn't determine, and 56% of failed drives did not raise any significant SMART flags (and that's interesting, of course, because SMART exists solely to survey hard drive health); other notable patterns showed that failure rates are indeed definitely correlated to drive manufacturer, model, and age;failure rates did not correspond to drive usage except in very young and old drives (i.e. heavy data "grinding" is not a significant factor in failure); and there is less correlation between drive temperature and failure rates than might have been expected, and drives that are cooled excessively actually fail more often than those running a little hot.

SMART nije ni zamisljen za to, tj. za apsolutnu sigurnost u radi, kao ni svaki drugi PFA. Moze nekad pomoci, ali ocekivati da ce uvijek reci "crknut cu za par dana" je apsolutno smijesno svakom onom tko se ikad bavio ikakvom granom tehnike.
