Hitachi is plummeting, which was first in the previous ranking! Western Digital retained its second place despite a failure rate increasing, while Maxtor is occupying the first place.
More specifically the failure rate for 1TB drives:
- 5.76% Hitachi Deskstar 7K1000.B
- 5.20% Hitachi Deskstar 7K1000.C
- 3.68% Seagate Barracuda 7200.11
- 3.37%: Samsung SpinPoint F1
- 2.51% Seagate Barracuda 7200.12
- 2.37%: WD Caviar Green WD10EARS
- 2.10% Seagate Barracuda LP
- 1.57%: Samsung SpinPoint F3
- 1.55%: WD Caviar Green WD10EADS
- 1.35%: WD Caviar Black WD1001FALS
- 1.24%: Maxtor DiamondMax 23
Hitachi is logically the less well placed, what with two separate lines! What about the 2 TB version?
- 9.71%: WD Caviar Black WD2001FASS
- 6.87% Hitachi Deskstar 7K2000
- 4.83%: WD Caviar Green WD20EARS
- 4.35% Seagate Barracuda LP
- 4.17%: Samsung EcoGreen F3
- 2.90%: WD Caviar Green WD20EADS
Overall, failure rates recorded are bad. That does not really want to entrust to 2TB of data to these discs alone: a mirroring will not be too much for securing data. Logically 7200 rpm disks are less reliable than the 5400/5900 rpm, with almost 10% for the Western model!
For the first time, we also integrate SSDs in this article type. The rates of failure recorded by manufacturer:
- Intel 0.59%
- Corsair 2.17%
- Crucial 2.25%
- Kingston 2.39%
- OCZ 2.93%
Intel stands here with a failure rate of the most flattering. Among the few models sold over 100 copies, displays a rate of no more than 5% VAS.
