    Hi guys,

    Last night I decided to test my drives to see how well short-stroking would work. However, I found some unexpected results.

    WD Green 1TB (5400RPM)

    WD Velociraptor 150GB (10000RPM)

    Given that the Raptor is doing almost twice the speed of the big storage drive, it's puzzling to see that transfer rates were only marginally better, burst rate is actually 73MB/s slower although access times were half.

    At this point I'm sure some jerks will give me some crap about this old drive. Bought it a long time ago to store big games (gtav, bf, watch dogs etc) but not played often hence no SSD, but never actually tested its speeds until now.

    Does anyone know why this discrepancy in performance? Does it mean it's failing or something? Drive health is reported OK in HD Tune.

    Transfer rates are OK. Because Green has much larger platter, it has "good" transfer rate with only 5900RPM (Intellipower).

    Access time is much lower with Velociraptor because higher RPM helps there.

    Burst rate test is useless. Yeah, Green perhaps can move data bit faster but 202 MB/s from HDD to motherboard is more than enough for Raptor as you can see from transfer rate results.

    So everything seems to be OK.
