Now I have a time to make some tests. What do I have: 1. FreeBSD 6.2-STABLE (updated yesterday near 20.00 GMT), non-SMP, SCHED_4BSD 2. Apacer 4GB Handy Steno AH320 Flash Drive (http://www.apacer.com/en/products/Handy_Steno_AH320_features.htm) 3. Trancend 1GB JF110 Flash Drive (http://www.transcendusa.com/Products/ModDetail.asp?ModNo=68&SpNo=1&LangNo=0) 4. File of size 550MB: -rw-r--r-- 1 minotaur minotaur 557092864 6 лют 14:29 test.avi Thus both drives support hi-speed. ----- I. Testing writing speed with Apacer (drive is empty) * dmesg umass0: vendor 0x1005 USB FLASH DRIVE, rev 2.00/1.00, addr 2 da0 at umass-sim0 bus 0 target 0 lun 0 da0: < USB FLASH DRIVE 34CH> Removable Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: 3936MB (8060928 512 byte sectors: 255H 63S/T 501C) * usbdevs -v Controller /dev/usb4: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 4 addr 2: high speed, power 200 mA, config 1, USB FLASH DRIVE(0xb113), vendor 0x1005(0x1005), rev 1.00 * time cp test.avi /mnt/usb 0.007u 2.821s 18:44.26 0.2% 21+285k 4348+136010io 0pf+0w ----- II.

As you can see Apacer is very slow on writing operations. -- Kind Regards, Alexander Shikoff minotaur@crete.org.ua Mob.: +380 67 946 31 49
