I just got the P2, and have 4x1TB drives (Seagate Barracuda ST1000DM003) set up as Raid 5. This is on the Thunderbolt2 connection. I see about 438MB/s Write and 210-220 MB/s Read. Do these numbers sound right? I think they are slower then my esata box that used the same drives (yes they where reformatted when placed in the P2 R4 box). thanks for the help.
