Buy Hitachi SATA 2 or SATA 3 drive? (FASTEST)


I just got a Newertech Guardian Maximus 2-drive RAID 1 enclosure and saw that BH Photo is selling the Hitachi Deskstar (0S0286) 3.0Gb/s 3.5" 7200rpm 2TB drive for $129(I think they incorrectly state it as 6.0GB/s but all other sites state 3.0Gb/s).

I also see the HITACHI Deskstar 7K3000 2TB 7200rpm 6.0Gb/s at Newegg for $140+$7.28 shipping.

I will be connecting the Maximus to a Firewire 800(macbook pro) as well as ESATA(PC) to transfer photographic/video data for backup storage to the RAID 1 Maximus as well as to other backup drives in SATA docks.

I've seen google search results that state Hard drives do not saturate even SATA 2 connectors.

Can the Deskstar 7K3000 push more data even on a SATA II pipeline? Should I spend the extra $20 on both drives to get SATA 3?

The Maximus uses Custom Oxford 946 eSATA, FW400(1394A), FW800(1394B), and Ox3100 USB 3.0 Integrated Chipset. I think it is only SATA I/II.

  1. The faster drives will only waste your money. The bottleneck is your port to the PC (Firewire and eSata).

    Do not spend the extra money for SATA3 drives in an external enclosure.
