128TB SD Cards Are Coming (theverge.com) 175

A new card specification has been announced by the SD Association that should let you store your entire media collection on one SD card. Technically speaking, the new card specification should increase maximum storage on SD cards to 128 terabytes with faster transfer speeds of 985 megabytes per second. The Verge reports: Right now the maximum storage space on an SD card is 2TB, and that limit was promised as far back as 2009, but still hasn't been reached. In 2016, SanDisk unveiled a prototype 1 terabyte SD card that would make it the biggest in the world, but it's still not available to purchase. At the time, SanDisk said that the advancement was necessary to match ever-increasing data-heavy formats like 4K video and VR. However, creating SD cards with massive amounts of storage is cost-prohibitive. SanDisk's 512GB SD card used to cost $800, and though it's dropped in price, is still priced around $300.

    • Correct. The standard allows for those specs, but no product with anything close to those specs exists.

        • The 2TB limit was done nearly 10 years ago, still no one has made a 2TB card.

            • But has anybody ever needed more than that in one's phone or tablet or camera? Also, even in Android 6 and beyond, even if one formats an SD card as internal memory, there are still certain apps - particularly system apps, that will insist on being on the physical internal storage, and won't touch the SD card. Storage companies are far better off selling Apple, Samsung, et al high density NOR flash ranging from 64GB to 512GB, thereby eliminating any storage issues for devices

Having said that the 128TB limit does seem rather pointless (but I suppose there's no harm). I doubt we'll see 10TB+ cards before 2030 which means it may have been better to wait to create a standard nearer to when it is useful.

          It's important to differentiate between the companies that make and sell SSDs and the companies that manufacture the NAND flash memory that is used in SSDs. In the case of the first, there is significantly more competition, but there aren't as many companies that actually make the NAND and it's those that have been accused of price fixing and possibly other anti-competitive behavior.

          I also expect that part of the reason SSD prices are falling faster relative to HDD prices is that the bare minimum material cost for an HDD is more expensive. An SSD is just a cheap enclosure around a bunch of NAND flash chips on a board with connectors, an embedded processor, and a few other components that are relatively inexpensive and subject to price decreases as a result of Moore's law. The enclosure for the HDD is more sturdy and made of more expensive materials and other parts that have more of a fixed cost that holds stable.

          One advantage that SSDs have is that NAND manufacturers have been willing to move from SLC/MLC NAND as used in the initial SSDs to TLC and now even QLC NAND, which has greatly increased the storage capacity of SSDs and even allows for greater capacity than you can get in an HDD assuming you're willing to pay the obscene costs. This does come at the expense of longevity as you get fewer program-erase cycles when using more bits per cell. For most consumers this doesn't matter as they're unlikely to hit those limits and any SSD is going to be a major speed improvement over an HDD.

          I do agree that HDD will likely be relegated to backup and archival purposes. I don't have many computers left that aren't using an SSD for their main drive and I can't see myself using anything but an SSD as a primary in future builds.

      Depends on whether your glass is half full or half empty, SSDs are way cheaper than HDDs a few decades ago. I'm thinking if we could magically make SSDs 10x cheaper, why not HDDs too? Then instead of 512GB SSDs and 4TB HDDs we could have 4TB SSDs and 32TB HDDs. I mean there's always a market for cheap bulk storage as long as there's significant savings.

    Why not just go for M.2 2230 instead of SD-cards? SD-card is 24x32mm, so it is actually bigger. And M.2 SSDs can be gotten in reasonably large sizes while being much more reliable (number of writes) compared to an SD-card. SD-cards reach up to 3W and the maximum for the NVMe spec is 7W (while actual SSDs like WD Black are rated at 135 mW), so power consumption is probably not a big factor either (especially considering the SSD will finish 20 times faster and go to idle).
