1. I already had a 2.5" hotswap setup
2. 2.5" 8TB SSDs are 4x as expensive as 8TB NVMEs.

Technically, SATA SSD's need to fill this spot as a cheaper alternative but with their prices being just as expensive (often only 5% cheaper) as m.2. If SATA had a price range in the 0.30 EUro/TB, it will have been a great alternative to HDD based storage.
And you can go really crazy with bifurcation > 4/4/4/4x and then converting all those new m.2 slots to 6 SATA (ASM controller for cheap and work great). Plop, 24 SATA ports for 4W power draw.
But nobody is going to pay for SATA SSD's when they can just buy m.2 for the same price. So the result is that the SATA SSD market is "kind of dying", and manufactures look at it like 2.5" drives got looked at from HDD manufactures.
Huh?
870 QVO 8 TB SSD SATA III 2.5 inch: $629.99
Which is in the same range as M.2 ones.
Sure, you are getting gouged if try to buy it on Amazon but then... just don't buy it on Amazon?

SSDs need to sit more between HDD/NVME's, but they are on the same level as NVME.
Another issue, is just like with 2.5" drives, you see manufactures really only focus on specific drives. Its going to be 3.5" or U.2/U.3 and now NVME NAS solutions. But you do see any 2.5" / SATA solutions?
I mean, the only thing i remember seeing is the Synology DiskStation DS620slim that is now like 5 years old product. And still expensive as hell. Nobody makes any SATA products.
The market is now being a ton of Chinese brands / mini-pc makers that offer 4, 5, 6 NVME products. And even with PCIe3.0 x1 lane support, they are faster then SATA SSDs. And benefit from the massive better random/lower latency.
I love to shove a ton of SATA SSDs in a system, instead of HDDs but the prices need to be somewhere in the middle of HDD/NVMEs per TB. Not the same as NVMEs.
