Shower thought about this: Instead of create a ULTRA FAST virtual disk by unused memory such as ramdisk, diskache.io can create a ULTRA LARGE virtual disk to cache.

So far I am not so impressed with ssd cache of HDD; people don't perceive mean latency so much as tail latency so long as you have an HDD attached to a windows machine it will take a lunch break.

With the now relatively-low price of SSDs, I don't personally see a huge need for this. Maybe 4+ years ago, but not now.

That is so very true. The worst part is - I had a prototype in 2012, but never actually finished it until now. Hope this will find its place in enterprise, where every dollar matters.

That's not so true. I'm usually very annoyed, when navigating my pictures or video collection, and thumbnails appear after several seconds. Same with large folders.

I have to agree with maxpert. When Windows 10 was about to be out, I was ready to bury that project, because both Linux, and OS X already had that, and I expected MS to integrate something similar. However, 1 year later it is still only available in Windows Server, and extremely hard to configure.

Regarding SRT - it is good, but bound to a particular hardware, so does not suite everyone.

8TB SSDs are still kind of expensive, and when you get to fill just half of that with a few million files on a HDD, just listing the drive contents becomes painfully slow. It surely wouldn't hurt to keep the small files and directories cached on an SSD with several orders of magnitude faster random access.
