> 2. 2.5" 8TB SSDs are 4x as expensive as 8TB NVMEs.

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?

And that is the core of the problem. Your buying a storage media that is a lot slower in sequential read/write, and also on random's. But your paying the price of the superior m.2 NVME's.

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.

		Yes, when you connect expensive NAND to a slow SATA interface, you get something expensive and slow. That's a fundamental issue with the choice of technology, not an issue with the market. That's why nobody is doing this with new deployments.

		> But you do see any 2.5" / SATA solutions? > Nobody makes any SATA products. Because there is no demand for it. 2.5" HDDs stopped to grow in size 10 years ago. If you need capacity you use 3.5" HDDs, if you need speed you use M.2/2.5" SATA SSDs and 2.5" SATA HDDs... what are these could be used for? There is no capacity with 2.5" HDDs, it's only 1TB CMR HDDs x numdrives, ie 5TB RAW for 620slim, 4TB RAW for TS-410E. Or you risk it all and use a 4/5TB SMR HDDs for a ~20~25TB of RAW capacity and now you can't use RAID. So what the point? > but the prices need to be somewhere in the middle of HDD/NVMEs per TB ... and why a SATA SSDs should be cheaper than the NVMe ones? Especially if they are both use the same flash modules? https://www.qnap.com/en/product/ts-410e/specs/hardware
