  • *stands up* Hi my name is ak47gen and I am a linuxholic

    Good evening...well morning in my case.

    I am fasinated with your benchmark system, after i was told to go here from AnandTech. I posted a topic http://forums.anandtech.com/messagev...&enterthread=y about my linux flash drive raid and someone mention from AnandTech that I should submit my info to phoronix.

    If your interested on the boot speed you can see it here at http://www.youtube.com/watch?v=ozA2ie10A6w#

    But as of now i am downloading all the programs from phoronix benchmark tool. Soon I will have a better estimate of how fast my x13 flash drive raid will perform under this.

    Let me know if this concept fascinates anyone and that you possible want to inquire more info. I spent a good time setting this up (flash drives suck because out of 5, 4gb drives only 2-3 will be the have the same sectors/head/cylinders).

    P.S. i did bonnie++ benchmarks but this phoronix tool, I have to give a lot of credit for being very easy and awesome to get all the benchmarks.

    . With raid 0 make sure there all the same size
    4. If you can use multiple host USB controllors, most cap out around 50 MB/s but can go up to 60. (i have 6, 2 on the mainboard, 2 pci cards, 2 pci express cards)
    5. if done right your looking at ~$200 for a ~210 MB/S drive with response times as low as 70 Microseconds for 52 GBs.(so a lot of money for little space, but faster than a x3 raptors on raid 0 *which is ~$400).

    ...And you shouldn't be either, assuming the only thing the drives are used for is loading the os, and programs. While that is reading intensive, it's not very writing intensive,

    It should go w/o saying that you shouldn't put valuable data on a Raid 0 array, etc, etc.

    No i got you, i mean 200 gb is essitally them saying 20 writes a day over the same stuff for 10 years. Thats why my ramdrive is no on the raid, but on one 8 gb. And i am not worried if it does die this is just an experament to get me back into linux.

    The problem is constant I/O. Of course you can write 200GB per day for 10 years with those. Probably. But note the details: 200GB per day means *once* per day. Plug it in, write 200GB on it, then remove it again.

    In your setup, there's constant I/O. That means there's probably an order of magnitude more data transfered than 200GB per day. Just make sure you take backups regularly

    "If one thinks he or she might actually try this, we
    suggest buying a Corsair Flash Voyager GT or a
    Corsair Flash Survivor GT USB drive. They are built
    with components guaranteed for 100,000 write
    cycles. With these, one can write over 210 GBytes of
    data to the drive each day, for ten years!"

    I have recieved 2 hard drives DOA. I think my chances might be better with the flash drives.

    I would but, i would have to force it to accept the same size, (they will be off a head or a sector) so transfer rates will be slower *at least from what i experance*.

    "I hope you know that flash drives don't live very long and it's not recommended to use them for anything else than data transport :P"

    Not sure I couldn't find any documentation on them dying out quicker, on top of that out of all the years i used my 128 mb lexar it never died. I would assume they live longer than a HDD since it doesn't have moving parts.
