A few years ago I was glad to find out that there is a new flash drive with on-board caching (the SuperTalent Express RAM Cache), which gave it a really neat performance on small files. I like running portable apps from my flash drive, as well as occasionally boot/run my operating system from an usb stick, so I was really happy that this technology was finally coming.

It seems to me (also from benchmarks) that this was a step towards having a small SSD with the form factor of a flash drive, really something with potential and demand (imho).

But since then quite a few years have passed, and this drive seems to still be the only one of it's kind.

The Question

So I was wondering if there are some drawbacks about hardware cached usb-flash-drives or something else that I am overlooking, since neither this company nor anyone else continued developing new devices with this capability.

Thanks in advance!

    There doesn't need to be a drawback for a product not to take off; it just doesn't have to solve a big enough problem to overcome inertia. See jwz.org/doc/worse-is-better.html

    or simply not be cost effective

  • You both might be right there (good article btw). It is still kind of sad though.
