Is write caching possible when using a CompactFlash card in linux?

Question

linux

There is an old laptop (PII-366, 192 megabytes of memory), which, despite its venerable age, copes well with the country duties assigned to it (reading books, ICQ, old toys). An inexpensive CompactFlash card connected via an IDE-CF adapter (a kind of analogue of an SSD) is used as a hard drive. As you understand, CompactFlash cards do not have a cache, and the operation of such a drive would be very slow if the flashpoint / flashfire utility did not come to the rescue, the site of which, alas, is no longer available. This program creates a small disk cache in RAM, after which Windows XP starts flying on this laptop as if it were not a Pentium 2, but some kind of Pentium 4. Lately I have been gravitating towards linux, and I think it would be quite interesting put CrunchBang linux on this machine as an experiment. However, information about the operation of linux on CompactFlash is contradictory. The question is, how will linux behave on such hardware, and are there similar tools for creating a disk cache in RAM for it?

Answer 1

Disk cache in RAM and so it is. Nothing extra is required.

Download block ram disk (brd), use it as a caching device.
If you cut power without sync, you will lose the contents of the card by 100%.
