I was looking at this page and was surprised not to see SAS drives in the list:
Top Picks for FreeNAS Hard Drives
Yes, 7200 rpm drives will generate more heat, but I'm surprised that for ZFS the reliability improvements that SAS drives seem to include aren't important if ECC RAM is so important.
Or is this site's info not relevant anymore with the mention of size of RAID vs the error rates we're likely to see? SAS vs. SATA - EnterpriseStorageForum.com
I'm looking at setting up a NAS of some sort, not settled yet on ZFS or BTRFS based, but was thinking about getting an SAS card + drives for the better reliability. The higher MTBF, lower error rates (including on the signaling side from SAS), and at least one drive doesn't seem crazy expensive to me...
For around $170-200 each on newegg (think one is 4kn and another 512n)
Seagate Constellation ES.3 ST4000NM0023 4TB 7200 RPM 128MB Cache SAS 6Gb/s 3.5" Enterprise Internal Hard Drive Bare Drive - Newegg.com
Seagate Constellation ES.3 ST4000NM0033 4 TB 3.5" Internal Hard Drive-Newegg.com
Yes, I've heard terrible things about some Seagate drives, but the alternatives seem much more expensive and might even have less hardware (like a WD Re 4TB SAS drive with 32MB of cache for $250). And I'd rather pay more now than buy another drive and need to deal with failures later, possibly after losing all my data.
If I planned on a case with hotswap bays I might be a little more willing to risk it, but I couldn't find anything "great" there. Mostly stories of loud cases, and some that might be killing drives with their heat (Silverstone DS380). There was an interesting option at u-nas.com, but it needs a 1u power supply and I'd rather use a standard ATX form factor (likely a quiet, efficient option).
Other than cost being a deterrent, if I'm planning to keep my drives well ventilated I think the higher RPM and reliability features should be worth it.
