Ok, here are my greatly improved results after upgrading to the V4p2 firmware and doing a factory reset (all data gone). I don't have IOMeter, but I did run SiSoft Sandra, which I believe to be generally accurate. Detailed Benchmark Results Buffered Read : 44.64MB/s Sequential Read : 37.67MB/s Random Read : 27.69MB/s Buffered Write : 47.00MB/s Sequential Write : 35.79MB/s Random Write : 36.94MB/s Random Access Time : 10ms This is a ReadyNAS NV with 256 MB and 4x 750 GB Seagate drives with X-RAID. Network is a Netgear GS105. Computer for benchmarking is a Dell Poweredge 400SC server with 2.4 GHz processor, Intel 1000 MT Lan. Jumbo frames are on. So, now I'll just see how that transfer rate holds up while reloading all of my stuff from the PC to the ReadyNAS. Update: After 8.5 hours of real world data transfer from my temporary storage back to the ReadyNAS, the average write speed is 25 MB/s. Overall, still pretty good. Better than I was seeing before....
