    A good record if...

    It is a good hard disk, designed and manufactured by a proven manufacturer, but, alas, a bad reading of its description (by me), made me confuse it with a hard disk with SATA interface (this one is with SAS interface).
    This mistake (which I made), does not question the quality of the manufacturing of the disk, but if one does not have the recognition of this specific format by the motherboard (even with a specific controller card, not accepted by my equipment), well one finds oneself with 800 grams of unusable high technology (alas).
    This disk works well (checked on a friend's PC who has mounted it as a server), but first you have to make sure that the controller chip of your own machine accepts this interface. If not, it is impossible to make the machine recognise it at start-up (problem with the driver/OS link), and its specificity (very short access times, long life span), makes it unrecognised.
    But for a server use (company, SME, graphic/audio studio), it's a very good choice, you just have to think carefully about the support machine that will host it.
