    I'm not really into benchmarking, but I just ran a HD Tach test because I was curious, and I ended up with this result:

    This is with a 200GB Seagate 7,200rpm ATA drive with 8MB of cache.

    Doesn't it seem a tad bit too good? I ran the test multiple times, rebooted the system and ran it again, and the results have been pretty consistent. I've been looking around the web, and my results seem to look better than the ones I'm seeing for 10,000rpm WD Raptors, other SATA 3GB/s drives, and even RAID0 setups.

    What's up with that? :D

    The screenshot in the first post was the Long bench (32mb zones). Here are the results of the Quick bench (8mb zones)

    Hmm that's pretty odd.

    Beat my raid 0 raptors : p



    It seems your read speeds are very very high at the start of the drive but slow down a lot near the end. The high start may explain your high score though.

    Yeah, I wonder why that is.

    Maybe that explains the speed of that Office 2003 install? :eek:

    Wow, you've past the point of the ATA saturation, that's amazing.

    NCQ??? or possably an SATA2 drive? or just an issue with reading the speed properly from your hardware?

    Regardless, drives pretty much never achieve, let a lone pass, saturation. You should market that computer as a super computer. With those benchmarks as support, I'm sure you could get a good chunk of change for it on eBay.

    No, it's a regular Seagate 7,200 PATA drive. You could be right about it reading the speed incorrectly though. Pretty odd. :D
    Oh well, I was just curious to see if anyone could think of a possible explanation.

    Bench the drive with Sandra and see if you get the same result.

    looks like cache burst at the start and then gradually starts using the cache less and depending on the physical read speed of the disk at the hub.

    If you are over clocking the FSB or Memory HD Tach may be getting bad speed info since it uses it's own device drivers.

    Other than that, like Lord said, you are probably just testing your cache speed, not the HD itself. The HD Tach website says the program uses 8MB or 32MB depending on the mode. Are you testing in 8 MB mode by any chance? If so the 8 MB cache may be masking the true HD speed.

    Everything is running at stock speeds. Haven't overclocked any of the components. I also posted screenshots of the test with both the 8MB and 32MB modes above, and the results were almost the same.

    I'll have to bench my 250GB Hitachi 7k250's when dabs.com delivers them :) thouhg it'll be post raid0 array. which may also incliude my seagate 200gb if I cant add a drive after creating said array.

    Too bad I threw away our old SCSI RAID server. It only held 24Gb with 4 drives but it was quick, bearings were whining and it was getting old.
