Detective work concerning Raid card.

Bought some raid cards rediculously cheap. Like £10 each from Scan. The XFX Revo64.

The card is visible to the pc as an IDE drive, idea being it`s `driverless`. The raid side of things is controlled by an SPU processor on the card, with it`s own cache memory and so forth. Benefit is the cpu is not used at all and the access speeds are somewhere around 80mbs. But that speed is constant unlike the troughs u normally get visible with the likes of HDTach.

I put one in a rig at home that would play games mostly, and the performance was terrific. Out of the blue tho, the array would fail, if u`r lucky only 1 of the drives would become uninitialized and a reboot and rebuild would allow u to continue... until `out of the blue` it would happen again.

Now, up to this point I`ve dismissed them as a bad idea, they were cheap - so eff it. The company NetCell, who are the brains behind them, have apparently gone bust, and there are quite a number of peoples over the net that have issues with them. That aside tho, people have issues with everything that comes out. Sell 1 million units, and a guaranteed 100 people will have a problem - shizzle happens.

The drives concerned are always checked after a failure, always turn out ok. Infact used on a sata 1:1 basis and they will give years of service.

I had a bit of time and equipment in work to set the card up and run some test stuff on it. Using the IOmeter, as linked to on another thread, and sticking 20g worth of stuff on the drives to copy/delete/defrag - really give the suckers some punishment.. it seems to be working ok.

This leads me to think about the hardware being used in both examples:

@home (gaming stable)

Abit AV8, 3800x2 @ 2.4 to 2.7, 2G (2x1g), 7600GT (something like 710/1950+), 400W SilverPower PSU, 1x IDE DVDRW, 1x IDE 80g, 3x 200g SATA (for the raid card), X-fi card, WinXPSP2 nLited.

@work (working pc)

Intel/Foxconn/HPCompaq, E6400 @2.1, 2G (2x1g), Onboard Intel, 365W generic psu, 1x SATA DVD, 1x SATA 80g, 3x 80g SATA (for the raid card), Onboard sound, WinXPSP1/2 in house build.

I`m leaning towards the overclock causing issues.. mainly cos I can`t think of anything else.
 
You used different drives for the test?

Home: 3x 200g SATA (for the raid card)

Work: 3x 80g SATA (for the raid card)
 
Yeah, more out of convenience, the 200g ones I was using are currently in a machine full of stuffs.

The 80g ones I`ve just ripped out of 3 stock machines.

I guess to be more critical I could/should regain the 200g and try them. But just to be clear, I`ve got 4x 200g and 2x 250g @home in service or in stock, and have tried combinations of them. The first time I got an error my initial thought was a drive was knackered, so I replaced it.. and it went again. Subsequently testing the drives that "went" - they work fine.
