whats your full zfs config you're utilizing with these drives, curious how it's all setup :)
Thnx
Click to expand...
So I have a 800TB pool, where I have 6 triple mirror of these drives, which give me about 11TB for metadata and small blocks.
ZFS by default creates a copy of metadata, and with a mirror you will basically have 4 copies of metadata. So instead I create a triple mirror and set redundant_metadata=none. With this I will have good protection and if one ssd fail and the second SSD has bad blocks, it can still heal during resilver. In most cases, having just a mirror of special vdev should be fine, most of us are scrubbing weekly and have backups? :) and you can set redundant_metadata to some or most also. Whatever you feel is safe for you. Note: I may be wrong here, but I think this is how ZFS work.

I have also set special_small_blocks=16k, which will save all small blocks up to including 16kb to the special metadata vdev. This is especially useful if youre using draid which doesnt have dynamic stripe sizes. And last I've added
Code: 
options zfs l2arc_exclude_special=1
to /etc/modprobe.d/zfs.conf
There is no reason to double cache metadata

Was anyone able to get anywhere near this crazy low prices on a 3.84TB drive? The best I could get was $165 on a 5200 ECO.

U.2 you can sometimes scrape $130. SAS was maybe $150/160 lowest that I got. I'd love SAS 3.84 @ $130

I have space on the desktop/server so I don't mind using multiple smaller ones, but the high capacity is for a more mundane case, that requires SATA (mundane being the PS4 :p )

How do folks use these in their NAS set ups? As metadata devices with striping/parity, or as your main pool?

I've had 16 of these in my cart for a couple weeks now I kept checking to see if people were talking about them here :D as a sanity check. I can't quite use them yet but wanting to build an all flash NAS out of a 24drive JBOD I have. It'll only be on 10GbE for now and I need space more than NVME-level speeds.

For a flash capacity layer these should be solid.
Ive tried some 25$/ea offers for 50 and 75pcs but not been accepted yet.

The wave of sm863a 960gb was at 60$/ea when the first 30$/ea offers started getting accepted.

By how more and more sellers starting to list the 1.92tb ecos below 50$ it should not be too long for one accepting low offers appear.
They are the hyperscaler models so the large sellers probably have them in the low 6digits, large waves like that tend to drive a race for the bottom.

If you're using HD Sentinel I gotta say it's a garbage program and you can ignore what it says about the health of a SSD. I have an Intel DC S3700 400GB drive that Intels's own software says has 40% life left and HD Sentinel says 100%. I have a 4TB spinner drive that HD Sentinel says has zero health left, back up and replace immediately. No other SW says this drive is bad and it's been functioning normally for the last 4 years. And as far as drive info is concerned, HD Sentinel displays mostly irrelevant and useless info and it does so inconsistently. For example, sometimes it will tell you what the drive interface is, SATA or SAS, and sometimes it doesn't. And most of the info is not available or N/A.

And don't even get me started on SMART data accuracy fo SSD's.

If you find bugs I have found the developer very helpful with fixing them.

Picked up a pile of these recently, all about 50k POH and about 2-4PB of NAND writes, so between 70-85% life left.
Decent price if you can't wait, but if you can wait I agree with others that the price will continue to sink.

For those with a bit more experience than myself: I am thinking of buying 8 of these to set up a TrueNAS instance with about 10 TB of usable space with dual parity drives. I imagine I won't need a metadata device since these are SSDs. Are there are any obvious drawbacks with this approach that I am not considering?

I think idle power on these is about 2 watts so that's definitely something to consider.

I ended up picking two from this seller (currently out of stock but looks like they frequently restock) for $45 each. SXPLFA Sandisk CloudSpeed Eco Gen II 1.92TB 6Gb/s SATA 2.5" Enterpise SSD | eBay

Both drives were marked with 93% life left and I verified via smartctl. They both have half the write count of those sold by serverpartsdeals. Definitely a good price.

They're currently being used as bcache devices for my btrfs mirror for my security system.

SMART Error Log Version: 1
Warning: ATA error count 15 inconsistent with error log pointer 2

ATA Error Count: 15 (device log contains only the most recent five errors)
        CR = Command Register [HEX]
        FR = Features Register [HEX]
        SC = Sector Count Register [HEX]
        SN = Sector Number Register [HEX]
        CL = Cylinder Low Register [HEX]
        CH = Cylinder High Register [HEX]
        DH = Device/Head Register [HEX]
        DC = Device Command Register [HEX]
        ER = Error register [HEX]
        ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 15 occurred at disk power-on lifetime: 34432 hours (1434 days + 16 hours)
  When the command that caused the error occurred, the device was in an unknown state.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  04 51 00 ff 00 00 00

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name
