Re: CHIA and PrimoCache
Urgent writes are those that Primocache essentially hands off to the OS without processing, because the cache is full. Mostly with plotting you're looking to reduce Total Write (Disk) by utilizing the memory. I was able to get my cache up to ~50GB on the L1 for plots, if I minified Windows services ...

Re: Replacing the DDR4 sticks while PrimoCache is still active
What InquiringMind said - RAM isn't hot-swappable. Never pull a DIMM when the system is powered on (that includes sleep mode). The only two modes that would be valid for this are Hibernating (not a hybrid hibernate), or completely shut down.

Re: Advice please
I eventually uninstalled Primocache and, since then, program loading time has become painfully slow (up to 3x as long as before). Any evidence that Primo uninstall leaves problems behind? An uninstall of Primocache should have zero (0) impact on your machine performance. It's likely that what you a...

Re: Is there any way to force L2 cache a specific directory?
FYI if the zip hashing doesn't do the job for you, I made an earlier post here to a file called readfile. I use this to do any precaching I want. It completely reads each file and doesn't seem to skip a beat except the reading of files that might be in use. I'll give it a look, thanks for mentionin...

Re: SSD Cache for USB-C DAS
Hi, is it viable to use PrimoCache for SSD caching of an external drive (in this case QNAP USB-C connected DAS)? Also does PrimoCache run on Windows Server? Any valid Windows volume can be cached by Primocache. If it's network connected, it needs to be an iSCSI volume to be cacheable. And yes, Prim...

Re: New Purchase Questions
What InquiringMind said. With a caveat: you can enable deferred writes without a UPS attached to the machine if you are absolutely sure it's rock solid (never BSODs, reboots on it's own, etc). If you do, keep the deferred time to 10s or less - it will help overall with write coalescing and keeping d...

Re: Advice please
Windows 10 also has it's own automated TRIM function built in, separate from the drive's own garbage collection routines/etc. You can set it up rather easily by going to optimize the drive, and clicking on "Change Settings" under the "Scheduled Optimization" area. You can even ov...

Re: Advice please
Does that mean things will continue normaly without over-provisioning? Thanks for the help. Well, over provisioning is a good idea on just about any solid state drive. It can help their lifetime significantly depending on how full the drive gets, and how often you TRIM. I usually go no less than 5%...

Re: Tiered L2 Cache
You seem to be overlooking the performance overhead of caching itself - for any read/write, a search has to be done on the index to see if that data has been cached (time taken being related to the index size, so a small index of larger blocks is quicker to search than a large index of smaller bloc...
