    well I just read a review on the 'new' gigabyte iram, on their sote its 4gb max, on another it said 8gb.

    either way a ram based hd has been wanted since they dropped them in the 386 days, just in the 486/p1 days it would have been very expensive due to ram prices.

    on a review I found they raided two of them and they achived 270mbs sustained transfer on random files...........

    Thing is this is a sata product on a pci caard, wtf cant they just drop the sata, and make it appear as a standard ide controller ?

    Thread Revival!!!

    I did this!
    This i to get a 0 DBi PC. 1 CF i working but slow. Im now goning for RAID:

    2 x 1Gb CF card
    2 x CF-> IDE adapter
    1 x IDE Hardware RAID card

    Tride 3 IDE RAID cards, "Promis 100" = noluck, "gerneric Sil0680" = OK

    Main intrest is DOS/Win98SE w. no swopfile.

    All ok untill formating disk. Then hung. Even after diffrent tricks.

    Now searching for a "highpoint 370" RAID...

    Yer english sounds good to me....

    I just tried the exact same setup with 2 samsung OEM 2GB 150x CF cards, a pair of CF - IDE adapters from eBay and a $20 3Ware 5800 old IDE raid controller. Although the CF cards can be formatted and accessible by windows xp if on a standard ide controller - this raid controller recognizes it and say that the device is not supported.

    so add the 3ware 5800 as one of the raid controllers not supporting the flash cards. although it does work using the win2k drivers on XP -

    I'm using a Kingston 8Gb Ultimate 133X Compact Flash in my car PC and I have say the system is extermly slow, even with 1Gb of Dual RAM (over 700Mb still avalible when using all apps) and a Dual Core CPU.

    Using a hard drive simply isn't an option for me, as there's so many bumps on the roads i get nothing but problems. Even with a 2.5" hard disk which has been positioned in such away to obsorbe shock, but if you get any up and down movement at all which is enough to knock the hard disk about inside then the hard disk head will move, likly causing damage to the surface of the disk and causing the computer to freeze reboot and scan for error's (this is what I've had to deal with in the past few years, used to happen every few months when ever i hit a large enough bump). I've replaced my hard disk twice in the past 2 years due to these problems.

    So if anyone here get's some CF cards setup in Raid and notices a vast improvement in performace I would realy like to know. One thing I found with compact flash is that you need to disable DMA Transfer Access or it will freeze every time you try to access it (read\write).

    I might give it a shot myself as I have a free IDE Raid card not being used, just need the extra flash cards and some IDE to CF adapters. I don't expect I'll be doing it anytime soon due to a lack of money, but if I did I would be sure to benchmark it both in Raid and out of Raid and record the results.

    I found this article today.
    http://laptopmag.com/News/Notebooks/...0-Go-Flash.htm

    Fujitsu announced that it has prepped two LifeBook Tablet PCs for the future with the announcement that customers can tailor the B6210 and the P1610 with solid-state disks for faster, more reliable performance.

    Besides options for traditional 40GB/60GB/80GB hard drives, the notebook can be outfitted with Samsung's solid-state drives. Available in 16GB and 32GB capacities (adding a hefty $700 and $1,200 to the price of the P1610, respectively), the flash disks enable instantaneous program booting, less overheating, and longer battery life.

    The time for affordable Solid State drives is getting closer. (It's still a long way off but it IS getting closer.)

    Because IDE is patheticly slow?
    IDE/PATA = 133 Mbps
    SATA 1 = 150 Mbps (the iRam only uses Sata-1/150)
    SATA 2 = 300 Mbps

    just thought i'd chime in, and post this link:

    Can't be used in RAID mode with removeable-type CF cards (which is most). Poor product development. They could have made it emulate a non-removeable drive but didn't bother.
