Hi
We're about to purchase a new Dell PowerEdge R630 or R730 server to host Windows Server 2012 R2 Standard and SQL Server 2014 Standard and I can't decide which disks to go with.
We've decided on RAID 10 (using 4 disks), a PERC H710P 2GB RAID controller and have a choice of 3 types of disks:
300GB 10K RPM SAS 12Gbps 2.5in Hot-plug Hard Drive [400-AJPK]
300GB 15K RPM SAS 12Gbps 2.5in Hot-plug Hard Drive [400-AJRU]
400GB Solid State Drive SATA Mix Use MLC 6Gbps 2.5in Hot-plug Hard Drive [400-AIGK]
There are also a couple of other disks available - SATA SSD Read Intensive and Write Intensive, but I've discounted those.
I've read that SAS is full duplex and SATA is half duplex and can see that there's a difference in the max transfer rate (600MB/s vs 1200MB/s) and I know that the IOPS for any SSD will likely be far higher than any spinning...
