Toshiba BG3 SSDs fit 512 GB in 3.2 cm²

That Toshiba XG5 is a pretty nice SSD, eh? Toshiba's storage division has been knocking it out of the park lately. That group has another new product to announce, and even though it's not nearly as flashy as the XG5, it's pretty exciting for entirely another reason. The Toshiba BG3 is the company's latest release in its BG family of low-cost SSDs, and it packs up to 512GB of 64-layer BiCS TLC flash memory onto a 30-mm-long M.2 card.

These drives are DRAM-less, which means their performance probably isn't going to approach that of drives like the XG5. However, the BG3s are thoroughly modern devices with support for the NVMe 1.2.1 protocol and a PCIe 3.0 x2 connection. Toshiba says the BG3 can read data at up to 1520 MB/s sequentially and write it back at 840MB/s. Those numbers are up pretty significantly from the BG2's figures of 950 MB/s for sequential reads and 400 MB/s for writes. The company doesn't offer any random access performance figures, but it does say that the BG3 supports an SLC cache mode that should help with those operations.

Since the BG3s have the flash memory and its controller all in one package, Toshiba will also sell you the BG3 in BGA form. The BG3's DRAM-less nature could mean that these drives come in at affordable prices. Toshiba says it's targeting the BG3 series at low-end and low-cost devices, and emphasizes that the drives save space and power compared to hard drives, while being far faster. Since the single-package BGA version is just 1.3 mm in height, the BG3 could feasibly find its way into positively petite portable 'puters. I just hope we start seeing these in entry-level laptops rather than 4200-RPM 500 GB hard drives.

Just don't expect these drives to show up at Newegg anytime soon, since Toshiba primarily targets them at OEMs. The company didn't reveal pricing, though it did say that prices will be similar to SATA drives of the same capacity.

    This is a product that I could easily see going into tablets, 2 in 1s , and ultra-books.

    It doesn’t feel like that long ago that I was impressed by the existence of 512MB thumb drives and SD cards.

    “it did say that prices will be similar to SATA drives of the same capacity.”

    Well I’ll be damned. Finally. And with a drive that arguably is pretty decent specification-wise, even if it’s half of what the top end can do.

      Anyone still using/manufacturing 4200rpm drives?

        I rage when I see these new laptops and I want to beat whoever decided it was a good idea to put these in.

      All of my family needs at least 500GB if it’s the only drive in laptop, and most need 1TB(+). We don’t have much choice now, SSD (256 or 512GB boot) + HDD (1 or 2TB storage). But two-drive-bay laptops are becoming rare, 1TB SSD premiums are huge, SSHDs are OK for just one or two of us. Hopefully OEMs won’t put just 128/256GB of these (BG3) like they usually do today; or at least use user-upgradeable M.2 socket version instead of soldering the BGA.

        What in the world is your family doing that they need that much space if they aren’t gamers? Your family should look into cloud storage for their photos and home movies, haha.

          My thoughts exactly.

          I do programming of image/video processing (among others) and often need big samples (like, hundreds of GB), and VMs for development etc. take space, too; that’s not counting “warm” archives and personal photos etc. One person is a filmmaker and lecturer and they gather materials for presentations etc; their external storage is on the order of 30TB. One is a photographer and when you count like 30MB per photo (with raws) and occasional video then 500GB is just about ten thousand photos plus Adobe Master Collection.

          Maybe you don’t consider that laptop can be primary PC, but it’s often unavoidable. Desktop PCs are just secondary ones for heavy lifting (like video editing).

          Even if it were home movies, not everyone is happy about cloud storage (speed, latency, access at all, transfer caps/limits, especially on the go), and that’s before we talk about privacy (or confidential materials on the business side).

            Yeah, that’s all fair. Usually when people say “my family” they’re talking about aged grandparents, selfie-obsessed teenagers, and other lightweight users, haha.

            (Although I still think using a laptop for your primary PC when you’re doing real “work” like that is folly.)

      I’m just still staggered that any vendor thinks a 4200-RPM hard drive is a valid boot drive option at all!
