I've been looking at options for external storage and I quite like the idea of plug hard drives in as needed like you can with Thermaltake's Blacx. The USB 2 speed limit doesn't really concern me but I'm a bit puzzled by the 1 TB limit to the disks it will work with.

It seems to me that it should work with any SATA compatible disk. So why the limit? Is this perhaps a purely artificial limit so they can sell us a new unit in a few years (the price per gigabyte sweet spot is already moving to 1.5 TB)

but I'm a bit puzzled by the 1 TB limit to the disks it will work with.

umm ... it says (under Features as well as under Specifications):

"Supports All 2.5” & 3.5” SATA HDDs up to 2 TB !"

"HDD Capacity: All 2.5” or 3.5” SATA HDD up to 2 TB"

Patented Design: 2.5” & 3.5” USB SATAHDD Docking Station, Supports All 2.5” & 3.5” SATA Hard Drives up to 2 TB !!

and AFAIK, 2 TB HDDs are the largest available consumer hard disc drives available as of now.

indeed. maybe OP is looking at a retailer's outdated info page -- or worse, outdated stock. – quack quixote Dec 29 '09 at 22:39
    
Yes, I was looking at a retailers page. Also, all reviews I found cited the same specs. I failed to notice that Termaltake's site specifies 2 TB. The question remains though, why specify a limit? Is it merely the maximum that they've tested it against? – Kris Dec 29 '09 at 22:51
    
Yes, this is the maximum they have tested against. – ChrisInEdmonton Dec 29 '09 at 23:00
    
as i said, 2 TB is the maximum size for consumer disks available at the moment. so, they play it safe and claim they're compatible with what is available at the moment. – Molly7244 Dec 29 '09 at 23:04

As of today (11.27.2014), only the base model of this product has the 2TB limit. All newer models, and I quote:

"Supports all 2.5" & 3.5" SATA I/II/III hard drives in ALL Capacities"

That is great news that the new models do not have any size limit on them.

Go for the 2 slot model. I have it and it is fantastic.

Welcome, and thanks for answering this question. Could you add a link in your answer for where the information can be found? – fixer1234 Nov 28 '14 at 5:11
    
Hi fixer1234. Here you go: Single Drive Unit - thermaltakeusa.com/products-model.aspx?id=C_00002058 Dual Drive Unit - newegg.com/Product/Product.aspx?Item=N82E16817153146 Scroll down and then select Specifications. Please let me know if that is not what you were looking for. – TaG Dec 12 '14 at 1:50
    
Looks like conflicting information on the dual bay unit. In one place, it says it's limited to 3 TB/bay. Right below that on the same page, it says "all capacities". I supposed that wouldn't be inconsistent if no 3.5" drives exceed 3 TB. However, the 1 TB limit in the question appears to be gone. Thanks for the links. I added them to your answer. – fixer1234 Dec 12 '14 at 2:54
