Enterprise 22110 m.2 NVME - Heatsinks? Placement?

[Dopamin3]

I'm totally new to looking at enterprise 22110 length drives. My Gigabyte X570S Aero G has four m.2 slots that can accept that length. I'm running zVault on it (the community fork/continuation of TrueNAS Core). I plan to populate them all, basically two smaller ones (480GB probably) for a RAIDZ1 boot volume for the OS, and two bigger ones (1.92TB) in a RAIDZ1 mirror for stuff like bhyve VMs and database storage. Upon populating, I'll lose SATA4/SATA5 and the bottom PCIe slot which is all fine.

Do these drives drives need thermal pad / heatsinks? And I assume I would want to check if it the drive is double sided and get a double sided one if necessary? This is in a desktop ATX with three front intake fans / 1 rear exhaust. Airflow would be somewhat present but nowhere near what a proper server has.

And then lastly I'm not sure on the ideal place to put the drives. M2A_CPU has a direct link to the CPU, and the other 3 are all going through the X570 chipset. The boot mirror will see the lowest activity and I don't care about bottlenecks but I want the two larger drives to have more priority access and try to limit the bottleneck. I'm thinking keep the two boot drives on the chipset, then the larger data drives with one the CPU and other one on the chipset. Page 5 on the manual shows the block diagram. Or maybe it makes sense to run both larger drives off the chipset for more "equal" sharing? But then I think it could be slower.

i don't recommend heatsinks that are just glued with thermal tape or similar. They fall off.

you should be looking at heatsinks like this

depends on the m.2 you actually got; samsung runs very hot, toshiba is bliss. Either way they were meant for high airflow.

Based on availability and being limited to PCIe 3.0 x4 I think I'm looking at:

480GB Lite-On EP1-KB480 (only gen 2 drive, but meh for boot it should be fine)
1.92TB Samsung PM983 or Kioxia XD51LN11T92

but is it really worth it to go with 'enterprise' nvme?

In my exp latest gen4/5 *gen5 even more when ran at gen3 speeds - finally gives you full gen3 performance without bad thermals. Endurance wise you might be surprised.
the 1.92T pm983 its endurance is under 1PB, and runs very hot.
the xd51ln11t92 is bit better on endurance going to 3.5PB but slow.

where hynix p41 2t has endurance of 1.2PB, some seagate nvme's going even further.

m2 isnt really an enterprise format anyway. And domestic usage is unlikely to need enterprise endurance, but if you want some just partition the drive a bit smaller.

You are completely wrong in your numbers. The Hynix P41 2TB has an endurance of 1200TBW which is listed right here if you scroll down: Platinum P41 SSD – SK hynix SSD

1200TBW = 1.2PBW
did i miss anything?

 

[Dopamin3]

1200TBW = 1.2PBW
did i miss anything?

lol good point. sorry I'm out of it today

The only reason I'd go for enterprise M.2 is power loss protection, which is particularly nice for databases with anything beyond a trivial write load, because they don't have to constantly sync metadata and cause a bunch of write amplification.

I haven't actually bought any 22110 SSDs, and I don't know how cooling goes, but when I have looked at them I always liked the Micron options, though they seem to be rather expensive at the moment.

Some other options include Samsung PM9A3 (PCIE Gen4) and Hynix PE6110 (PCIE Gen3).

Publicly available firmware for the Hynix SSD is either non-existent, or was never released.

Is u.2 not an option? With u.2 you have more options to mitigate heat-problems IMHO.
With the heat-sink for m.2 22110 it's probably clever to get some height measurements of the components (Controller, NAND, DRAM-cache and PMIC -> they can get hot too), to apply the correct thickness of thermal-pads, and look to not crush the PLP Capacitors if they are the tallest components on the PCBA.

I would try the samsung pm9a3 or pm983, the micron 7450 pro if i where forced to m.2, or even the 375GB P4801X Optane . For the Kioxia XD5 i would first search to get infos on the latest FW and try to get it (on Eepay i spotted 104 and 105).



PS: I never had an m.2 22110 drive at all, but for an external SSD with ICY Dock's 22110 compatible USB-C Case (ICYNano MB861U31-1M2B) , it's quite interesting. But risky too, F/W-update yourself the JMS583 Chipset...
