As a cache for a very large file, can partitioning it speed up its random access performance? I have a huge file, almost 8TB in size. Although I don't fully open the file for each read but read from a specified offset, I'm considering using SSDs and RAM to accelerate access to this file. The built-in cache in Linux seems to have no effect, and I'm wondering whether using a Content Addressable Storage (CAS) system would be effective?
