Questions on L2 Cache & "Prefetch Last Cache" Settings
Posted: Wed Jul 21, 2021 2:04 pm
Hi all,
I've been using PrimoCache for a year plus and it's awesome, but I have 2 questions I haven't been able to find answers for.
To begin, here's my basic setup:
RAM- 32GB DDR3 1600Mhz (Corsair Vengence)
Primary Disk- 500GB Samsung 860Pro SSD (512MB DDR4 onboard cache)
Secondary Disk/L2 Cache- 16GB SanDisk SDSA5GK-016G-1006. Transfer rate is a lot slower than primary (220MB/s read, 50MB/s write vs 560/530 for Samsung)
CPU- Intel Core I-7 4820k @ 4.1GHz (OCed from 3.7)
Questions:
1. Does the "Prefetch Last Cache" feature only apply to the L1 cache? Also, where does it save it's data?
2. If this setting saves to my primary (faster) Samsung SSD, do I even need a L2 set up, given how much slower my secondary disk is?
Overall, my goals are to make use of that old 16GB SSD as a L2 (why not), but only if it's beneficial to performance.
Thanks,
