I have just installed a PCI Express -USB3 card (on a XP PRO SP3 machine) and bought an USB3 external hard drive (WD).
Then have done some speed testing with Diskwriggler on the local USB3 drive and the NASLite on a gigabit lan
Here are the results (min, avg, max) MB/s
USB3:
Write 31.6___35.8___42.4
Read 75.4___82.1___84.3
NASLite:
Write 41.8___53.8___75.6
Read 20.4___21.0___24.0
I find the write speeds of the USB3 quite low (like an internal sata disk). The read speeds are really nice. Probably some caching /read ahead somewhere...
Write speeds on the NASLite are real nice (faster than on the local disks!). The read speed is very slow. I wonder what is slowing things down. Any ideas ? Where should I start looking ?
I'll have to test the read speeds on another computer on the same lan...
