Hard drive enclosures

I'm gettting confused about hard drive enclosures, which I know very little about.

I have built a system for a friend with an Asus A8N SLi Deluxe motherboard. This comes with an external SATA bracket (including power connector).

He wants to buy an external enclosure for back-up and moving data around. So, I think, great, get an enclosure with an SATA interface because this will be faster than Firewire and USB. But then I think it would be nice to have a USB interface too so that he can hook it up to his non-nforce4 PCs (and other people's PCs). Why not have 1394a/b as well to speed things up if external SATA is not available.

Then I start wondering about the internal interface. Surely, for maximum flexibility, it would be good if the enclosure could take both IDE and SATA drives. Maybe he just needs an enclosure that is big enough for him to fit any necessary adapter inside.

Then, I think about hot-plugging/hot-swapping and whether he would need support for SATA-II either from the enclosure or from any drive that he puts in or both.

Finally, I think about build-quality, including heat and noise issues, and also about price.

So, you see, from my uninformed perspective, there seem to be a lot of issues and they don't seem to be covered in much depth in reviews I have read. I have looked at Tom's review of 15 enclosures and I have trawled Storagereview's forums and I am still not clear on what solutions are out there. None of the enclosures reviewed at Tom's accepts both IDE and SATA drives - do they even exist, or can one get one that will work with an adapter?

Tom's review mentions the Lindy ME-720U2SI, which has external SATA and USB, but it only accepts IDE drives internally. Confusingly, in the review of it, he starts by referring to the ME-720U2IDE as an alternative enclosure with external SATA - but paradoxically he says about this model, with "IDE" in its name: "it's clear that it won't take an IDE hard drive".

Guidance or links please!

I've never heard or seen of an enclosure that supports both PATA and SATA interfaces. That doesn't mean they don't exist, they just don't exist to me. :)

What exactly would he be using the external drive for? For me, I use an external USB2.0 enclosure with a 40GB drive in it for data backup and USB/Firewire is plenty fast enough, IMHO. If he's thinking about using it on other systems, then I'd go with USB2.0 for maximum compatibility between systems.

Here's a device that offers an external to internal SATA connection. Doesn't look like it will support USB/Firewire connections from the rig though.

IMO, this is a limitation that will prevent the flexibility of connecting this device to any other computer that does not offer an SATA port, so it would make sense to get a an external USB/Firewire enclosure instead, one that has support for internal SATA drives.

Take your pick of external enclosures from this page.

Thanks guys. Use will be fairly open-ended. Back-up (not only type); storage; sneakernet; anything else. That's why I was thinking that flexibility would be a good thing in such a device.

Looking at this thread on SPCR, it seems that hot-plugging is an issue with chipset and driver support, and also requires some kind of power-down signalling electronics in the enclosure. Silicon Image controllers seem to get a good report in this regard, so I might see if the 4 SI ports on the A8N will support this kind of thing. However, it looks like this feature is difficult to guarantee ex ante.

This device looks like it might meet some of the requirements, although the price is high. It runs $170 including one tray, additional trays $50 !

Features include:
Hot-swappable removable trays. One type of tray for 3.5" IDE drives, another for 3.5" Serial ATA drives.
Enclosure provides dual FireWire 800 ports (daisy chainable) and a single USB2 port
Same enclosure accepts both SATA and IDE trays
Quiet, fanless, all-alluminum enclosure.
Holds up to 400GB drives

So no external SATA connector but it does have 1394b and USB.

I am currently using an external case with a 80 GB SATA drive as a data drive. It works OK except for the fact that it gets random "delayed write failed" messages because Windows cannot accepot the fact that a SATA drive is removable, and it is not possible to turn off the delayed write cache.

If you haven't done so already, you should look at that thread on SPCR that I linked to above. Some people have had success by uninstalling (not disabling) the external drive from within Device Manager before they power it down.

Just look for a Firewire 800/USB hookup via PATA +IDE trays as it'll travel just as fast externally and price performance is the best thing going today IMO
