Hi,

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.

Thanks.
