Usable normal 2,73TB (located at 3 Tb / 1.024 ^ 4) for non-computer Affine prospects.
On my NAS Benchmak I came to 67MB / s read and 94MB / s read speed.
Compared to C't Test 8/2012 at 1000MB were 65MB / s and 85MB / s
Compared to a WD20EARS (62MB / s 83MB / s)
Decisive in deciding WD30EFRX red vs. WD30EZRX was me, the small price difference (+23), but 24x7 hotline and 3 year warranty.
Next interesting for use with HW RAID controllers acc.Manufacturer is the fact that the plate by the NAS FW will not be dropped so quickly, thus permanent Recover is pins must. Had this experience with div. RAID controllers beforehand.
