Data Security and Hybrid-Solution

[anbu]

Primocache is a great app. But I would like to see something here that could also contribute to data security.

1.)
PrimoCache should offer an option to ensure that system-relevant data from the system itself never ends up in the cache. In the event of a system crash, this would not permanently disrupt Windows (or its updates, which could be in the cache).
In other words:
It should never cache disk management writes or system/kernel accesses. It should only cache the files of users and his programmes.

2.)
Also, I would like there to be an option to write the contents of files until a program is completely done with it, and then write the entire file to disk in one go.

Yes, it sounds like a kind of hybrid between cache and a temporary ram memory. But that might be a great solution that combines certain advantages from both worlds.

Thank you for your suggestions!

The problem is that PrimoCache is a block-level cache program, at the disk sector level. It caches disk sectors and does not know any file information. Therefore, all file-related features are not easy to implement. In the future we may combine with file-level cache software to implement some file-related features.

NB That eBoostr, which is what I use on an Optane, has closed down......!!!
It is a L2 type, read only, file aware caching system, allowing the exclusion/inclusion of files by name, type, path and size.

I found that it was worthwhile caching my NVME drive with it if:

• I used a modded Intel driver, from Win-Raid. (Only the .inf or is it .ini file is modded and readable with a text editor)

• A properly aligned (for Optane) partition and exFAT file system with 4K clusters, Based on this paper: https://research.cs.wisc.edu/adsl/[list ... ce.312457/
  ie: eBoostr can cache more than drive at a time and is quick!!

• Message Signalled Interrupts enabled for the caching drive. https://forums.guru3d.com/threads/windo ... ol.378044/

• The caching software was given a one step higher priority, which increases CPU but NOT I/O priority.

This gave me just over 300MB/s of Q1T1 R4K read speed.
Affining the software to one (AMD) core complex did not help in my case as I did not know which other I/O related software to affine to the same CCX and did not pursue it further.

My 2 SSHDs are, striped (RAID 0) using Windows' Dynamic Disks, then also cached via eBoostr:
Striping or RAID 0 confuses the Seagate SSHD read cache (doesn't work), hence eBoostr, but does double the random writes. (and sequential)
With this I got lower game load times than installing the game to my SSD: https://www.techpowerup.com/forums/thre ... ce.312457/
ie: eBoostr can cache more than 1 drive at a time and is quick!!
