Yes, but they are also 10bT. Max B/w is 1.25Megabytes/s theoretical - 1MB practical. If you copy files, it will be noticeable laggy. For $35 they have a 100bT kit...but in either case it is a bit costly. You can get on a $10 or FAR router deal, throw in some $5 generic NICs, and cable...either make however you long you need for $10 max. Just need Cat 5/5e/6 wire [available at Home Depot for like $.10 a foot] and connectors you can crimp yourself with a small screwdriver and a hammer.
But, again, for a person not wanting to mess with networking this is a good deal.
*edit* Rather, the unit in the OP is a 10bT hub...
