Compare to other solutions

For SSHD software like (sort by name)

• AMD StoreMI/FuzeDrive
• Intel CAS
• PrimoCache

Disadvantages:

• These software count disk usage frequency by sector,
  and usually you can't specify what to hold in cache: this process rely on algorithm.
  Some are good, others just act like a joke.
  
• For Intel CAS, it won't cache Windows system files, so startup time is still slow.
  There is no way to bypass the limitation.
• Price.

Advantages:

• The good is they can load data from SSD, which is much faster than HDD,
  may allow system startup faster, or may not, depending on how you use them.

For RAMDisk software like (sort by name)

• AMD Radeon RAMDisk
• virtimus/imdisk (Open source)
• prsyahmi/GpuRamDrive (Open source)

Disadvantages:

• These software take fixed amount of RAM/GRAM to create a virtual partition even if empty.
• If install software inside it (save as image mode), once have to dismount for any reason,
  can't access files until mount again.
• If not install software inside it (browser cache), you still open them from slow HDD.
• Price if you choose a commercial one.

Special - Diskeeper DRAM caching

Disadvantages:

• No SSHD support, only RAM cache.
• Max cache size limit to 12 GB for unknown reason,
  their customer support provided useless solution (say to reset default settings).
• Price.

Advantages:

• Although this one use "by sector" algorithm,
  it can preload files you specified by command line.

Special - eBoostr

Disadvantages:

• Bad cache algorithm works only 10% of the time.
  For example, very prefer to cache picture jpg files, why?
• Price.

Advantages:

• SSHD support.
• Allow custom cache priority (not fully customizable...)

Finally - mhtvsSFrpHdE/prefetch

Disadvantages:

• No SSHD support, only RAM cache.
• No algorithm, rely on manually user config.
• Not a driver level solution, rely on operating system cache mechanism.
  Depending on platform, effect can differ.
• Not work well with Diskeeper DRAM caching when RAM usage > 80%.
• Official build only support Windows platform.

Advantages:

• By use fully customized user config, indeed speed up Firefox startup.
• Work on user level so can integrate with any other SSHD solutions.
  Or called custom what to cache to benefit from SSHD.
• Source code use Qt instead of platform specified API, cross-platform is possible.
• Price.
