bug or feature - direct L2 write cache without using L1 ram cache
Posted: Wed Aug 16, 2017 2:18 am
PrimoCache version: 3.0.0 beta
Cache Settings: 1GB L1 / 32GB L2 / integrated cache strategy with 10 sec defer write
Windows OS: Windows 10 Creator updates
Hardware Information (CPU/Motherboard/Memory/Harddisks): Lenovo Yoga12 / Broadwell i7-5600U / 8GB memory / 1TB Toshiba
Description:
So if I use read/write cache strategy for both L1 / L2 and later disable L1 completely, I noticed defer write immediately went to the L2 and then to the hard drive afterward. So if you want to setup a L2 read/write cache only, this would be the way. Great for people that don't have enough memory for L1 cache.
It seem the defer write options are greyed out if you put a zero a value for L1 when setting up a new cache for read and write mode.
May as well make this into a feature set for direct write back to L2 without L1 being enable. Performance is tad less without L1 but just as fast.
