I have a 64Meg stick sitting here...was thinking a cascade type scenario....swap to flash first off then connventional disk later...
Or possibly use it as a logging "disk" for /var/log as mine are getting hammered....
I don't have any kind of flash drive, but it happens I have a laptop
drive plugged into my USB port. Here are peformance figures of much
interest to me atm:
kowari:~# hdparm -t /dev/hd{a,g} /dev/sda
/dev/hda:
Timing buffered disk reads: 152 MB in 3.03 seconds = 50.17 MB/sec
/dev/hdg:
Timing buffered disk reads: 120 MB in 3.03 seconds = 39.60 MB/sec
/dev/sda:
Timing buffered disk reads: 60 MB in 3.00 seconds = 20.00 MB/sec

First is a WD 120 Gb drive on my new cheap (cheapest I could find)
Gigglebite mobo.
Second is a WS120 on an Abit hotrod66 that required me to use a 2.3
kernel for support when it was new.
Third is a 40 Gb Hitachi laptop drive in a cheap USB2 enclosure in a
USB2 connector on the cheap mobo.
The kernel is 2.4: 2.6.7 is about 35 Mbytes/sec on the first and I'm not
thrilled.
Test the speed of your flash drive as above. If nothing else, there will
be people here who're curious about how it stacks up.
