Toshiba has announced that it had started sample shipments of its latest UFS storage devices based on its 64-layer BICS3 3D TLC NAND memory. The new devices are compliant with the UFS 2.1 specification and can offer very high performance for demanding mobile devices, such as smartphones, tablets, and VR headsets.

Toshiba did not reveal when it plans to ship its UFS 2.1 storage devices powered by BICS3 3D TLC memory in its press release, but it is logical to expect the chips to end up inside 2018 smartphones and other devices. Earlier this year some makers of handsets suffered from shortages of NAND flash in general and UFS 2.0/2.1 devices in particular, so Toshiba’s upcoming launch of its new UFS 2.1 storage will be appreciated by the industry.

Toshiba’s new UFS 2.1 storage devices based on the company’s 64-layer BICS 3D TLC NAND memory will be available in 32 GB, 64 GB, 128 GB, and 256 GB configurations. The storage devices come in JEDEC-standard 11.5×13 mm package and use two full-duplex HS-Gear3 lanes with 5.8 GT/s data transfer rate per lane. Toshiba advertises up to 900 MB/s sequential read speed and up to 180 MB/s sequential write speed for the 64 GB model while also promising improvements of random read/write performance. Meanwhile, the 32 GB SKU is naturally slower than the higher-capacity models due to lower parallelism.

The manufacturer says it uses an in-house developed UFS 2.1 storage controller for the new devices. The company only mentions its expected functions, such as performing error correction, wear leveling, logical-to-physical address translation, and bad-block management, but does not elaborate.

    It would be so awesome to have small-ish phone with a 4.5" 720p display, maybe an SD625, some of this UFS storage and a 4000+mAh removable battery. Decent camera too, Xiaomi has shown me great things can be done in a budget of INR 7000 (price paid for my Redmi 2 Prime).
    Such a pity we're served big to mega sized showcase pieces that eventually become obsolete as planned.

    Check out Samsung's 2018 Galaxy A series. Not sure about the battery capacity, but they always had great battery life (better than the S line for tyre same size), and everything else in terms of specs seems to be top notch.

    I'm seriously thinking picking one up after a good price drop in the summer.

    I've always wanted the A3 but they dropped the generations after 2015 in my country.

    Amen, brother. I'd like a 4.2" 720p display myself, but it's all about huge screens nowadays...

    Samsung doesn't even sell the A3 (the small one) in my country anymore. =/

    Exactly the same in my country too, where do you live? Can only get the A5 and A7 in India. Sony too discontinued the Xperia Compact series after the Z3 Compact. No X, no XZ Compact...

    What's next after UFS 2.1? Is 3.0 and 4.0 still planned?
  • tuxRoller - Monday, December 4, 2017 - link

    Nvme, or, in general, any protocol that doesn't require addressing ssds with protocols that were intended to be used with disks and, in particular, very thin protocols that present open channel devices (eg, the lightnvm extensions to nvme).

    Host-controlled storage devices are the most practical way we have to do bounded latency storage io without something like xpoint or massively over-provisioning hardware.
    This leads to a much better user experience in mobile as it partially collapses the storage stack to enable intent-based management decisions.

    The better question is if we are ever going to see the UFS memory cards that Samsung "preannounced" in mid 2016. Does Samsung think the memory card format competition is too great to absorb USF cards as well? Or is it a licensing thing?
    UFS (both internal or external) is strangely SCSI based rather than PCIe based (like NVME). So SCSI made a belated consumer comeback in the mobile space!
