Problems when installing SSD, help!

Since I have a lot of drives around, I decided to do a bit more benching of drives for curiosity's sake

500GB Seagate momentus hybrid (2.5" ~70% full and run on an older core2 lappy with vista)
Seq 71.74 73.24
512k 23.02 32.52
4k 0.268 0.595
QD32 0.709 0.595


2TB Seagate usb3 external (3.5" 35% full)
Seq 123.1 121.5
512k 46.1 28.03
4k 0.565 0.326
QD32 0.598 0.325

Same 2TB drive as above but in a usb2 port
Seq 32.42 28.13
512k 20.69 26.55
4k 0.557 0.324
QD32 0.579 0.324

128GB M4 (16% full)
Seq 479.6 196.9
512k 362.7 179.3
4k 23.33 44.68
QD32 312.3 179.2

750GB Caviar Black (2.5" 2% full)

Seq 126.2 124.5
512k 47.59 69.76
4k 0.668 1.295
QD32 1.590 1.359

I will note that the momentus xt hybrid drive feels faster than it looks in the benchmarks because it selectively stores ~4GB of frequently used small files in flash; it selects the small files that get used a lot (like drivers while booting windows). That performance boost doesnt appear in a benchmark like this since the drive cant adaptively add the files that crystalmark writes to its flash cache.

Also, it does appear that the drive on USB3 is performing exactly as I would expect an internal 3.5" mechanical HD to perform, except USB3 appears to not allow high queue depths. the results are essentially unchanged between QD1 and QD32.

 

very interesting...

thanks for posting that
