Re: Impact of L2 caching using an SDD that boots Windows

Yes, you will still benefit almost the same as when using separate SSD. Only thing to keep in mind is - PrimoCache will use same resources as your Windows installation. Windows itself doesn't do much I/O when it's up though, so no real issues there. Btw, my boot SSD is 500GB (Windows+Apps+some games...

Re: [2019-12-31] PrimoCache 3.2.0 and 4.0.0 alpha released!

Feature Requests: (assuming you want a better, faster product than the competition!?) :) 1: A 3rd non volatile caching tier: Cache HDD to SATA SSD to NVME or Optane SSD. For majority of users (aka 99%+), this is not needed. You may want this if you like to see huge numbers in synthetic tests. And f...

Re: Dual boot Win10 - Linux

It won't work. Problem is Windows reading from that part of drive. Simplified example: You read file 'X' under windows. It's now also in L2 cache of PrimoCache. You reboot to Linux and modify file 'X'. You reboot to Windows, and try reading file 'X' - it will read from L2 cache, so what it was befor...

Re: Dual boot Win10 - Linux

Only way to make it work is use only read cache in PrimoCache, AND mount as read-only F: filesystem under Linux. All other options will lead to corrupt filesystem and loss of data.

Feature request - sequential cutoff

One thing I really miss in PrimoCache is option to specify sequential cutoff (like for example bcache has). This is especially important for smaller cache drives, as it'll help prevent just one single big sequential read to push out most data out of cache. This would also help issues like making bac...

Re: L2 cache and data not filled in again once it's out

From what I've tested, it only applies to L2 cache.

Re: L2 cache and data not filled in again once it's out

Hi, yes - I'm positive windows cache was flushed, as 'Total Read' was increasing, and in Windows Task manager,'Standby' memory was zeroed too. Also, I was always checking disk activity, both on SSD and HDD through Task Manager (if it were read from Windows cache, there would be no disk activity). If...

L2 cache and data not filled in again once it's out

I tested a bit to try and see what algorithm is used for L2 cache. Mainly it seems like LRU. However, I did notice a bug (feature?) - once data falls out of L2 cache, it cannot get cached again (even if using or not using L1 with L2). With using only L1 I did not notice same problem though. I flushe...

Re: What should be Optimal Settings for Gaming on this Specs?

Well, did some tests.
It does indeed seem to be simple LRU algorithm, but there seems to be a bug in it too. Once data that was in cache falls out of it, it cannot get cached again. Will open a ticket about it.

Re: What should be Optimal Settings for Gaming on this Specs?

L2 cache works basically with LRU algorithm. Basically - when filling up, all reads from HDD are 'copied' to L2. When L2 is full, data that is used last (or not used) is replaced with new data that is used. 64GB cache is generally enough for several games. However, copying lots of stuff around on dr...
