I use this 1TB drive (formatted EXT4) to store my data. This is a quick SATA2 disk, reliable and quiet (which is hardly surprising with Western Digital) Moreover it is one of the few who is not constantly promo ... but no matter because its price is right especially against its perfs and low consumption. For my part I only purchases of WD, internal and external. I have 2 more 32MB cache it by 64MB. They all revolve nickel including one on a NAS "house" formatted as UFS freeNAS.
Disc delivered quickly and in perfect condition by Amazon, I recommend the eyes closed.
