Seagate has introduced the Exos M series, a range of enterprise-grade mechanical hard drives available in 30TB and 32TB capacities. The two models, the 30TB CMR ST30000NM004K and the 32TB SMR ST32000NM003K, each offer a minimum of 3TB per disk and use a standard 3.
Not sure whether we’ll arrive there the tech is definitely entering the taper-out phase of the sigmoid. Capacity might very well still become cheaper, also 3x cheaper, but don’t, in any way, expect them to simultaneously keep up with write performance that ship has long since sailed. The more bits they’re trying to squeeze into a single cell the slower it’s going to get and the price per cell isn’t going to change much, any more, as silicon has hit a price wall, it’s been a while since the newest, smallest node was also the cheapest.
OTOH how often do you write a terabyte in one go at full tilt.
I don’t think anyone has much issue with our current write speeds, even at dinky old SATA 6/GB levels. At least for bulk media storage. Your OS boot or game loading, whatever, maybe not. I’d be just fine with exactly what we have now, but just pack more chips in there.
Even if you take apart one of the biggest, meanest, most expensive 8TB 2.5" SSD’s the casing is mostly empty inside. There’s no reason they couldn’t just add more chips even at the current density levels other than artificial market segmentation, planned obsolescence, and pigheadedness. It seems the major consumer manufacturers refuse to allow their 2.5" SSD’s to get out of parity with the capacities on offer in the M.2 form factor drives that everyone is hyperfixated on for some reason, and the pricing structure between 8TB and what few greater than 8 models actually are on offer is nowhere near linear even though the manufacturing cost roughly should be.
If people are still willing to use a “full size” 3.5" form factor with ordinary hard drives for bulk storage, can you imagine how much solid state storage you could cram into a casing that size, even with current low-cost commodity chips? It’d be tons. But the only options available are “enterprise solutions” which are apparently priced with the expectation you’ll have a Fortune 500 or government expense account.
It’s bullshit all the way down; there’s nothing new under the sun in that regard.
