I have no experience with these, but I was noticing this review
earlier on a device that is reported to work well with linux:

<http://www.amazon.com/iStarUSA-v7AGE420-ES-Trayless-External-Enclosure/product-reviews/B001LDMHFQ/ref=dp_top_cm_cr_acr_txt/185-1350060-5210125?ie=UTF8&showViewpoints=1>

Unfortunately the review doesn't mention Linux distro or version.

I realize that probably doesn't help the OP, given that he already
bought his hardware, but maybe it will help someone else.

[If you're looking at this message in the archive and the above
link is dead, the short version is that the iStar USA model
v7AGE420-ES 4 bay chassis is reported to work well]
