  • yep, real fake. then if you wake up you can buy such devices (it is really cheap) and try:

    mdadm --create --verbose /dev/md0 --level=5 --raid-devices=5 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

    mdadm -As /dev/md0

    that is all magic (in your words 'fake').

  • who did not undestand what is this? yes, it is hub with 5 flash drives which are set as raid 5 device under linux. i used this to test array behaviour after one disk crashed (I simply took out flash drive). how do you test monitoring of raid arrays? are assembling them from read hdd/sdd drives? lucky you, I'm not so rich.

  • no, this video was made when I had compaq evo n400c with USB1.1 ports only

  • Thats great man, how big is the usb drives :?

  • 5x1GB, cca 4.75GB as raid5

  • @maxshortte1982 linux of course

  • WHAT is the point of this? :)

  • Yeah, bet the array doesn't last that long either.... USB drives are good for like 10,000 writes?

  • Wow did this back in the day with OSX 10.2. Was Loads of fun!.

    Course back in the day, the only way to get real speed was to have 3 PCI USB cards and have them all raided as as RAID stripe. Got 4 MB a second, and learned that those flash drives Fail pretty fast. Best lesson ever...

  • RAID 5 With pendrives !!! WOWWW !

  • @leetware If the hub goes out you replace it. The data is fine. If one of the usb sticks goes out you replace it. The data is fine. If the usb port it is connected to goes out you plug it into another port or computer. The data is fine.

  • its all fake

  • @beasy26062 Nothing fake about it at all. Have done this experiment myself. :-)

  • @beasy26062 I would say you are the NOOB that knows nothing about doing this setup using Linux. :-)
