![]() ![]() Adding NAND chips also increases power consumption. When manufacturing at scale it is cheaper to make a 20TB 2.5" SATA drive than 20 1TB NVME drives that sell for under $40 each.Controllers have a limited number of channels, so now you need either more controllers or bigger ones. Adding more storage, especially in the 2.5" size format, just scales with the price of NAND chips. They have even gotten under $200 for 4TB. 4+ TB NAND devices have been plummetting in price and entering the full consumer market. Lmcnabney said:We are already seeing the endgame. So, if conventional platter densities stopped increasing and HAMR adds cost and is slow to ramp up, then the natural expectation should be a plateauing of prices! Just look at automobiles: they've pretty consistently gotten more expensive, even though they're based on technology and there's been pretty vibrant competition in that industry. There's no natural law of physics that says everything technological must get cheaper with time. The way HDDs get cheaper is by increasing density, so they can either offer the same capacity using fewer platters or offer more capacity with the same number of platters. Have you read about HAMR drives? The reason they're doing that is conventional recording densities have basically hit a wall. Since 2020 the price for the exact same type of drive and capacity has been rock solid and newer/larger drives just have higher prices.There are other explanations than them "deciding not to compete with each other". ![]() Prices have been dropping steadily (price per MB/GB/TB) since they were invented decades ago until three years ago. Lmcnabney said:The problem is that there are only three manufacturers of HDD and they have decided not to compete with each other. The industry's solution to this is to keep a strong price advantage over NAND, but they just don't want to do it. Once higher capacity SSDs leave their specialty niche and go after consumers the HDD market is done. When manufacturing at scale it is cheaper to make a 20TB 2.5" SATA drive than 20 1TB NVME drives that sell for under $40 each. It is maintaining some profit margin now despite a huge drop in units sold. By keeping HDD prices higher instead of dropping to maintain a strong value position the industry is dooming itself. They are also an order of magnitude slower in performance. HDD may still cost 50-60% less, but they take up more room, consume more power, and perhaps most importantly, they produce more heat. Kind of like GPUs.ĭata centers are already gearing up to make the move to NAND. Since 2020 the price for the exact same type of drive and capacity has been rock solid and newer/larger drives just have higher prices.
