NAS Box Hardisk Selection

We are planning to buy EMC NS-120 storage for CIFS file share. This model will support SATA, ISCSI & FC Hard disk. I am confused on which hardisk to select. My IOPS will be less than 20. Please suggest.

sata will most likely do and certainly cheapest - however you need to look at what configuration you will be running in, as the Raid level will also effect performance as each varies between read and write perfromance

We are planning for RAID -5 or RIAD 6 DP
find attache excel having max bus speed of verious interface.latencey would be tradeoff with cheapest disk.you can check SATA 6G if these disk are supported by EMC NS-120

Western digital or Netgear

You'll have to look on your usage. If you are going to have many 'power users' - read people who won't use the NAS for simple office document storage- SATA will quickly show his limitations compared to SAS/iSCSI
Less than 20 IOPS? Then a couple of 2TB SATA disks mirrored would suffice. How did you derive this figure though, it's less than one would expect from a single user's PC.

It does not support "SATA, ISCSI & FC Hard disk." since there isn't such thing as an iSCSI hard disk, it supports NAS (CIFS, FTP etc), iSCSI and FC connection to hosts. It supports either SATA or FC disks, a curious mix if they're to be on the same bus, maybe the SATA ones have an interposer on them similar to HP's FATA ones.
