I have a question, I have the IWill Raid 66 in a win98 SE configuration. I was wondering if in your setup did you have Drive D showing in my computer. If so is there away to not have this drive shown or is it just going to be there? I know it's the second drive in the Raid configuration but it not avilable for use which is the reason I'm asking can this drive be hidden? Thanks and I hope you understand my question.

Your second drive should be hidden -but this all depends on what kind of array you are actually configured for. It seems to me, maybe you are running a RAID 1 (mirror) and didn't sync the data from the Iwill RAID BIOS. I have not run into that problem -even with a RAID 0. Sorry I'm not much help. You may want to shoot that question over to Iwill. Thanks for the feedback

What's up with your scores? Im running win 98se,2 quantum 66/7200 in RAID 0 and my Sisoft disk bench score is 25,567.

What's with the meager performance increase w/RAID 0?

I saw in in the comparison of several RAID controller cards that they're all pretty similar.

On the other hande, see
http://www.tomshardware.com/storage/00q1/000329/fastrak66-14.html
where transfer rate increases essentially linearly with the number of drives.

Thanks

Noah

first, don't trust tom's hardware, second, that might be because of the 66MB/s bus being a limiting factor.
what about comparing that card with Promise's one?

The 66 MB/s limit was why the transfer rate didn't quite quadruple with 4 drives.

The RAID card comparison test did show that the Promise card performed somewhat better than the Iwill.

It seems to me that striping two ~20MB/s drives connected to a 66 MB/s bus should very well be expected to show a nearly 2X transfer rate. Otherwise, why bother?

From Toms Hardware -
"You can see that only in the inner and slower zones a stripe set of three or four is supplying triple or quadruple the bandwidth."

because there, quadruple the bandwidth isn't much, anyway, Tom uses Seagate drives as his reference drives, while currently the only IDE drives worth considering are Quantom's, IBM's and Maxtor's (you know that IBM computers got Maxtor hard drives?)

I think the best RAID implementation for this card, and in fact, for any card, subject to support or the card itself, would be RAID 10 (or 1+0). Admittedly, it is more expansive than the other two (requires 4 HDDs). However, your report was about SPEED only, I guess, but data protection is not less important, and essentially, was one of the main reasons for RAID implementation as such. Also, in terms of speed, nothing was mentioned about PCI 2.1 support. Clearly, if PCI bus width is doubled, coupled with other "goodies" like ATA 100, this card should be rated quite positively.

i'm quite new to raid and have a question: can i upgrade from a single drive system to raid1 without data loss (re-installing the original drive). i guess with raid0 it's not possible anyway, is it?
