Hello I have a few questions about reducing the SSD wear using primocache (L1 cache)

Will my whole drive get corrupted if my PC didn't shutdown cleanly? or will it just be a small part of it? (that can just be fixed using CHKDSK)

Does block size matter?

And which mode do I use for Defer-Write ...

So I had a power outage and my cache reset (L-2)
Is that normal?

Edit:
should I turn off my L-1 cache because I don't want my boot drive to get corrupted

Why would I want to turn on write when I also might just want my read speeds to be boosted
And my write is 0% because I don't want to reduce my SSD's lifespan

That's just for checking the L2 performance in Benchmark tools like CrystalDiskMark, otherwise their testing data will not be cached ...

By default, PrimoCache set the cache poliy to "100% read" for level-2 cache. That is, level-2 cache only cache read-write and ignore write-data. This is best policy for most real scenarios. However, this default setting will show no performance boost in benchmark testings. If you want to check the ...

For your specific scenario, the test parameters matter a lot. If you have a test size larger than your cache size, it will "spill over" and go to urgent writes, which drops the performance of the target drive.

Additionally, how full are your two cached drives (1TB + 500GB)? I typically have a ...

So I'm trying primocache thinking it's increasing my drives' speed but it isn't
I'm using L-2 cache on 2 hard drives (1tb + 500gb) 32GB of cache
So I try using CrystalDiskMark and I run it on the drives
The reads and writes are 51MB/s then I turn off the cache and run it again and I get 150MB/s
Am I ...

Very expensive though

When does it do that?
Because I've waited about 30/20 minutes and it only discarded about 10MBs of cache

By default, L2 cache is set to 100% read only and only caches read-data in order not to wear SSD too much. If you use L2 cache to speed up writing with defer-write, there might be much write wear on L2 SSD devices and may reduce the SSD lifespan.

So should I turn off deferred write and put it to ...
