I have a couple and use them on my U5S (486SX) 33 (256MB) and P3-500 (4GB) DOS builds.

So far they are fast, and trouble free, although I haven't exactly been torturing them with writes.

Good to know, thanks for getting back so quickly. Just put an order in for a Hyperdisk 8GB, specs states 150MB/s so we'll see how it goes.

A lot of them come without the power cable, which they need.

Luckily the one I ordered comes with the molex adapter - majority of the Ebay jobs seem to ship sans power cable.

I like IDE DOMs because they make for a very clean looking build but there are a couple things to remember:

• They have clasps that attach very firmly and can crack the plastic guard rails around the IDE headers if you are not careful
• If you have a Pentium or newer system and want to do speeds faster than ATA-33, you need to either ground pin 34 or attach with an 80 connector cable
• If you are doing the faster speeds, the larger capacity DOMs with multiple flash chips often seem to have higher max throughput capacities
• The guts are usually simiar to an industrial CF, but like industrial CFs, there's a lot of different guts that can go in there. Here's photos of 3 recent ebay purchases:

And here are some older ones…

Another good call above.
Those plastic clips! I chopped mine off with a pair of side cutters. It locks into the base of the IDE connector and wont let go at all.

Nice link there, I didnt realise it runs as ATA-33. But I use mine with NT4 so I guess I never would notice on a file server that just has the OS on it.

Out of all the different controllers pictured, in theory, the EDC 4000 / Innodisk looks the most interesting with the wide range of supported IDE modes and support for wear leveling. I'll test them out some time next week.

Cant find out much about the Silicon Magic SM223TF AC

They can work, but fastest would be m.2 sata on a pci sata card.

There is a all in one card for sale from rabit computing if I am remembering the company name correctly.

Personally, I use promise sata II tx4 card with a 2.5” to m.2 adapter
