    Hiya I recently replaced an aging 80gb ATA100 drive in my workstation (Q9650 CPU, 4gb DDR2-1066, Nforce 7 Mobo) and I was having trouble with what to replace it with. I had a choice between using a spare 72GB 15k Cheetah U320 drive and a spare 32bit PCI Adaptec 29160 controller (limiting the drive to U160 operation and 160MB/s bandwidth) or forking out £45 for a Samsung spinpoint F3 500GB drive.

    In the end I decided to buy the F3 and benchmark both drives then if the F3 lost I would add it to my mediasart server, heres my results:
    HD Tune (Spinpoint F3)

    min MB/s: 76.2
    Max MB/s: 144.2
    Avg MB/s: 119.1

    Access time: 13.3ms

    Burst speed: 159.8MB/s

    CPU usage: 4.5%
    HD Tune (Cheetah)

    min MB/s: 47.5
    Max MB/s: 72.9
    Avg MB/s: 63.3

    Access time: 5.8ms

    Burst speed: 73.3 MB/s

    CPU usage: 1.9%
    Crystal Diskmark (Spinpoint F3)

    Seq Read: 151.1MB/s
    Seq Write: 150.1MB/s
    512K Read: 48.55MB/s
    512K Write: 59.80MB/s
    4K Read: 0.58MB/s
    4K Write: 1.084MB/s
    4K QD32 Read: 1.146MB/s
    4K QD32 Write: 1.1MB/s
    Crystal Diskmark (Cheetah)

    Seq Read: 76.32MB/s
    Seq Write: 67.33MB/s
    512K Read: 51.71MB/s
    512K Write: 42.59MB/s
    4K Read: 1.271MB/s
    4K Write: 2.389MB/s
    4K QD32 Read: 3.344MB/s
    4K QD32 Write: 2.687MB/s

    Well thats pretty conclusive, being limited to the 160MB/s bandwidth of the U160 controller didnt effect the Cheetah as a single drive wasnt enough to bottleneck the bus. The F3 is very impressive, it may have been battling an 8 year old opponant but the retail price gap makes up for that. for large sustained file transfers the F3 is the man however I am more interested in the access time and the ability to read a lot of small files very fast and in this area the Cheetah manages to stay ahead so It will be the drive I use and the F3 will find a new home im my Mediasmart server where its cpacity will actually be put ot use.

    I hope my research is of use to anyone else who needs to make a similar decision (because old U320 drives on a U160 bus Vs SATA2 Juggernauts is a very common question ^^)
