    Hi all,

    I've been contemplating upgrading my iMac 27" Late 2009 from it's current 4TB which I upgraded 3 years back. I have narrowed down to 2 :-

    1) Hitachi HGST Ultrastar HE8 8TB costing approx $600-650
    2) Seagate Archive 8TB for approx $275-300

    As the name in #2 suggests, since it's archive its performance is lower. I'm wondering if an old iMac like mine would benefit from the performance of the HGST to warrant double the price or would it be a waste. The fact I'm considering it means my budget would cover the HGST however if I'm not going to benefit from it 'cos the iMac 2009 is too old, then I may as well go for the Seagate Archive.

    Any recommendations? TIA.

    A little bump. No thought to this anyone??

    Both disks are SATA 6Gb/s (iMac 2009 only 3Gb/s), 128MB cache. HGST is a 7200rpm, whilst Seagate is 5900rpm. HGST has a latency of 4.16ms vs Seagate is 5.5ms

    So it seems the HGST is double the price primarily for the 7200rpm vs 5900rpm & latency differences (with the bottleneck being down to SATA II interface of the iMac). Would those differences be noticeable for double the price?

    Look into the new Seagate 8TBs. Specifically ST8000NM0045. Very nice drives with very good expected reliability.
