My main concern with this option is energy usage. The CPU's TDP is 65W, the CPU in my current server's TDP is 35W.
It does have a few advantages over my current setup:
- More RAM 8 → 32
- Better CPU, passmark score 4766 → 8091, threads 4 → 8
- Ability to use RAID, current setup only has the capacity for 1 drive.
Is this a good option or is there a better option? I've also been considering using an external drive enclosure with software RAID, but I heard that could be unreliable.
EDIT: Is the price good? Shipping is quite expensive (about $100), so I'm only planning on buying it if the deal is good.
If you're as paranoid as me about data integrity, SAS drives on a host adapter card in "Initiator Target" (IT) mode with write-cache on the disks disabled is the safest. It will degrade performance when writing many small files concurrently, but not as badly as with SATA drives (that's for spinning disks, of course, not SSD). With a good error-correcting redundant system such as ZFS you can probably get away with enabled write cache in most cases. Until you can't.
