Before buying a SSD here's a link to some interesting information about these little beasties. There seems to be two different grades and the consumer grade has some undesirable artifacts as per this quote:

"The consumer grade drives (the Adaptec, Apricorn, Dot Hill and Ritek systems) showed dramatic variations in response times (latency) under sustained write conditions, which some vendors are calling the 'write cliff'."

For us folks that use BIAB on laptops the USB drive is a necessity but the fans on the unit enclosure supplied are pretty loud and distracting. If you have "golden ears" the whine of the drive can still be pretty annoying even without the fans. (I disconnected mine and have been monitoring the heat but there have been no issues or heat generation of any significance so far.)

I have ordered a new HDD enclosure to try out and will report here if it makes a significant difference. I hope so!

Otherwise, I can't say enough good things about the new BIAB audiophile version. I've waited for many years for something like this and feel it is absolutely outstanding. Highly recommended.
