>When a WD Blue 1TB SATA 6 Gb/s 7200 RPM 64MB is $46 on Amazon and a Crucial MX500 1TB 3D NAND SATA 2.5 Inch is $134.

those are cherrypicked numbers because 1TB is at the very low end for HDD sizes. compare with a more typical HDD size (3TB or 4TB) and you'll see the differences become more obvious.

I don't know about you, but 500-1000 GB is more than enough for my SSD needs, so the comparison at 1TB is much more relevant to me than at 4TB.

Wasn't the parent discussion about a new high-capacity HDD and the per-capacity cost of HDD vs SSD? I don't think that people satisfied with under 1TB are relevant to that topic.

In that market, people are comparing a pile of disks in an array to a pile of solid state storage needed to replace its capacity. The bulk price of storage inverts when it is cheaper to store hundreds of TB on huge SSDs rather than on huge HDDs. That would be the death of HDD, since nobody really wants spinning disks in their datacenter.

> a pile of disks in an array to a pile of solid state storage

It doesn't even need to be a pile of disks. Even for a PC the differences are big.

My computer has a 1 TB SSD which is a decent size for an SSD. It's still a bit tight for me, so I complement with a spinny rust NAS. If I had an HDD instead it would have been like 8 TB and I wouldn't necessarily need the NAS. I think that's what GP is hinting at when he says "me SSD needs". I think he's also complementing with HDD somewhere for bulk storage (be it external drive, NAS or even cloud storage)

If I'm GP, yeah; I use 250-500GB SSDs as primary disk and have a small NAS with a RAID1 of two 5 TB disks for slow archival storage. For that slow archive, though, I don't care what factor SSD price is to HDD price (as long as it's still >1.0).

[loeg]

Sure, that's fair.
