Toshiba BG4 1TB NVMe SSD Review – What the Future Holds


The elephant in the room with respect to the Toshiba BG4, of course, is that you cannot get your hands on it…unless of course you happen to buy a ultrabook or similar device containing this storage medium.  Even then, we will guarantee that you won’t see the fact that it contains the Toshiba BG4 within advertised anywhere on that ultra…but who knows right?  The good thing is that this is very small form factor NVMe SSD that has one heck of a punch.

The performance of and capacity of this single chip design SSD is what is truly special though.  1TB of storage is a massive amount of storage and 2.3GB/s is extremely fast data transfer performance for any SSD.  I might even venture to guess that something such as this in a digital device might even be integrated…permanent…non-replaceable and upgradeable.  But then again, it could also be integrated leaving an extra space for additional storage…

We now have high performing and high capacity SSD storage smaller than a SD card.  Editor’s Choice and great job Toshiba!

    Wow! Now if we could only get micro SD and SD cards with even just half of this kind of performance. Maybe a new architecture will come about to replace the current woefully slow (especially at random 4K) architecture of micro SD cards and SD cards.
    The world of storage is obviously evolving though.

    Thanks for the review Les.

    Interesting how in ATTO the read speeds peak at 128kb queue length, and taper off after that as queue length increases
