  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Is this a bad option for a home server? (lemmy.world)

Image transcription:

Processor: (3.40 GHz) 4-Core Intel Core i7-6700 Processor

Memory (RAM): 32GB (2x16GB) DDR4 PC4 U Memory (for i-series/Core Processors)

Graphics Card: Integrated Graphics (with i series processors only) +$0.00

Drive 1: 3TB HDD SATA 7.2k 3.5" Hard Drive

Drive 2: 3TB HDD SATA 7.2k 3.5" Hard Drive

M.2 Storage: 512GB M.2 SSD NVMe Drive

Price: $291.95

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.
