SAS and SATA Drives for PowerEdge R710 / PERC H700

Hi,

We currently have a PowerEdge R710 with 6 x 3.5" Drive bays and a PERC H700 RAID controller. We are looking to build a configuration that has at least 900GB (pref 1TB) of SAS storage (10K or above) and about 8TB of SATA storage. We were thinking a pair of 900GB SAS drives in RAID1 and then four 4TB SATA drives in RAID5 with a hot spare.

Is this configuration possible and, if so, do Dell have suitable drives or would I have to go for a 3rd party drive? We have plenty of spare 3.5" caddies but if they are 2.5" drives what is the part code for the 2.5" to 3.5" adapter or would we need a new caddy?

TIA.

Ian
