I was about to purchase Dell R710 for my small business. The server's specifications :-
Since R710 come with embedded 4 x Gbe which will be fully utilize for LAN storage. The question is regarding the hard disk speed. What kind of HDD do I need to utilize 4 gigabit NIC? From the calculation I need 512MBps transfer (4096/8).
1. HDD speed not overkill the network speed
2. HDD speed not lower than network speed
6 x 450GB 15K SAS 6Gbps
6 x 600GB 10K SAS 6Gbps
6 x 500GB 7.2K Nearline SAS 6Gbps
6 x 500GB 7.2k SATA 3Gbps
Raid 5 or Raid 10. Simply said, I need average write and read speed +- 512MBps (4xGbe)
• I'm planning to use H700 Integrated with 512MB Cache
• I only need 1.3-1.5TB array size which divided into 4 LUNs
• The system purposely act storage server for LAN environment
Why wouldn't you simply get an R510/R515 which allows you to have more disks connected to the RAID controller? They aren't that far apart in cost and this is what they were designed to do. Also if you are only using 6 disks you can pretty much rule out SATA.

I agree with XLHost, if your after disk performance you need more spindles therefore the R510 or R515 with 12bays fully loaded with SAS drives is going to give you some serious disk I/O.
