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.
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!
