Yep, I use 2 of those multilane SFF8484 cables on my HP P800 SAS Raid controller - but there's enough channels in there to drive 4x dual-port SAS drives - the one end connects to the raid card, and the other end, in my case also SFF8484, to the HP 8-drive drive-cage.
I haven't seen anything similar for single SATA drives, except those various 90-deg angle Sata cables, you can find some examples over at
Performance-PCS
Hope you find what you're looking for, also verify Sata1 vs SataII before ou buy.
