I'm looking at the DELL PowerEdge™ R720 from Hetzner.
This server has a Dell PERC H710 8 Port SAS/SATA 6GBit/s raid controller.
I have the choice between:
- 3 x 600GB SSD (MLC SATA 3Gb/sec)
- 6 x 600GB 15k rpm SAS disks
The price between both options are the same.
I need at least 1,2 TB of disk space, more is better.
The server will be used to host ESX 5 development machines. Mostly heavy reads, not that many writes.
Which option would be more performant?
With the 6 x 600GB SAS disks I would also have the possibility to put them in RAID 10 (and of course RAID 5). With the SSD's it will be RAID 5.
