I use bare drives for archiving, I've got about 50 of them. I use the BlacX dock for temporarily accessing the drives and it works flawlessly or I use a Kingwin KF-91 Serial ATA dock mounted in my computer with removable drive trays if I'm going to be working with that drive for a while. (The Kingwin dock has forced-air cooling as opposed to the drive just standing there in free-space with the BlacX dock.)

I buy all my Seagate bare drives from Newegg and they come with a molded, plastic clamshell carrier. These have worked well, but I like the plastic carriers from your link, although, they're $5 where the ones I have been using come free with the drive.
