From My Experience:
\Western Digital s solid, plug and play and has a 3 year warrantee-
OWC lowered their prices lately and is designed for MacBooks and Macs.
some Members and I had problem with Seagate and their software downloading just to read and write.
and what im doing now is using one enclosure and 4 ssd drives for 4 macs
that frees uo space and is more cost effective in the long run.
hoped this helped!
