power requirements of OSB flash drives

Prev: Can a (second) hard disc consist of only 1 extended/logicalpartition? Or is at least one primary necessary?
Next: CD player replacement
From: Hactar on 20 Apr 2008 18:08 So I'm shopping for parts for an MP3-playing computer, to replace my 200-CD carousel (that just forgot all the titles to my CDs). I quickly realized SSDs are crazy expensive, and provide performance I just don't need. (I sleep in there, so silence is paramount; heat is important too, as the case is fanless.) So I decided to go with thumb drives. One won't cut it because of size and reliability, so I figured I'd get five 16 GiB thumb drives and use software RAID 5 (? N drives + parity) to turn them into a ~64 GiB volume. (1) How to boot? Slap stuff on a CD, and do what LiveCDs do to have the boot disk unmounted? What is that, anyhow? Use another thumb drive and make sure it stays mounted ro? (2) I was reading a user comment at newegg, and he said regarding a hub: "If you plan to plug in anything that needs power from the usb port, (...flash drive...) don't bother. This cant provide enough power to do any of it." Now here, I've never had problems running a flash drive from an unpowered hub. Then again, I've never tried to run five of them. I realize they have to have _some_ power. So how much power do flash drives use actually? 10 mW? I'm looking specifically at http://www.newegg.com/Product/Product.aspx?Item=N82E16820208378 The technical information says only that it's "USB powered". -- -eben QebWenE01R(a)vTerYizUonI.nOetP royalty.mine.nu:81 Drive nail here > < for new monitor.
