Good options for enterprise grade M.2 SSD?

I have been using Intel P4500 and P4600 U.2 SSD’s for some time now in my home server builds for download drives and write-heavy drives. The long write lifespans on these have been really helpful since I have them being written basically 24/7 for weeks or months at a time.

However I also am using all tower-based systems with consumer motherboards, so I dont have any native U.2 ports, and have been using the M.2 → U.2 adapters, or PCIe to U.2 adapters.

I am getting tired of the extra point of failure these adapters introduce, and the M.2 → U.2 ones especially require extra SATA power cables from the PSU which is becoming an issue as well. So I would like to try to swap these drives for something that is natively in the M.2 form factor that does not need an adapter (I dont have any PCIe slots available anymore…)

But every time I try to search Google or eBay or elsewhere for M.2 SSD’s, I get only listings and information on consumer grade versions. I am having a pretty hard time getting info on available data center and enterprise grade models in the M.2 form factor. The internet is basically just flooded with consumer M.2 SSD stuff. So I was wondering if anyone on here had suggestions of specific models of drives that might be easily available with a write lifespan of 1PBW+++ in a size of about 2TB, give or take a few TB. Suggestions?

But there is still hope yet.

Difficult to source (for mortals):

fwiw I dont actually care about speed at all, I am not even close to saturating PCIe 3.0 since my write speeds are limited to my ISP download speeds anyway.

I did notice the Phision Pascari drives pop up in a few searches but had not yet looked into them since they seem pretty unfamiliar and did not have any sort of reviews or details on Newegg. I will look into that more then

I also noticed that it seems like many of the Intel varieties for M.2 come in 22110 size, which also would not fit in my motherboards… example New Intel P4511 2TB Enterprise level SSD Hard disk NVMe M.2 22110 2000MB/s | eBay

Enterprise and M.2 22110 pretty much go hand-in-hand. You’ll find M.2 2280, but you’ll have fewer choices.

oops nevermind looks like 22110 might fit after all

something like Micron PRO7450?

Why not use an HDD? HDD can last quite a long time and are very inexpensive.

I use an old 2TB HDD as my downloads disk. Qbittorrent writes to it while the torrent downloads. Once completed, it’s moved to my ZFS pool.

I do not feel a need to backup the downloads disk. The ZFS pool is backed up off site.
