I suspect the reason is due to high base costs. Throwing on more dram chips and a better controller probably don’t cost much, but drastically effect performance. So, the cost savings of a simplified drive may only be a few dollars.
- Dylan16807 4y agoThere's a good chunk of price to performance tradeoff. Taking samsung as an example, currently their lower end is $95/TB and their higher end is $125/TB. WD currently has a cheap QLC for $75/TB and a gen4 drive for $140/TB. This is looking mostly around the 2TB range, and mostly M.2 It's hard to physically fit large amounts onto an M.2, but a 2.5 inch SATA drive would hold a big pile of QLC flash just fine. I suppose the SATA bottleneck just looks bad. Maybe if we had better consumer support for 2.5 inch drives with NVMe then companies would be more willing to make that size.
