A good drive. 1

I bought these discs for their 5-year warranty. Additionally performance are satifaisante (110 mo / s read and 130 mb / s write).
A bit expensive compared to other range but quiet because it pays for failure WD change the disc without flinching during the warranty without even requested bill.

I have used them to make a RAID 5 with 4 disks with an IBM 5014. I obtained by reading 350 mb / s write and 330 mb / s.
