Re: Help explaining write cache

...if any write cache is configured (e.g. anything else but 100% read cache), newly created files are not visible to other computers on network, just on a machine that created it... If an existing file is changed (with write caching enabled), are the changes then visible from other computers on you...

Re: Prefetching drive order

RobF99,

How about running separate cache tasks for your C: and D: drives, if you have a good idea of how to split memory between them? You can then enable Pre-Fetch on both caches but enable the Boot option on the C: cache task only, so it (pre)loads sooner.

Re: New Purchase Questions

Glad to be of help. There is a configuration discussion thread, but that seems to have been hijacked by RAM uber-geeks. :) The biggest decision is whether to use L1 and/or L2 caching. L1 should be used if you have RAM to spare (which seems to apply in your case - if you're maxing out at 20GB usage o...

Re: [Support OS] What about supporting Linux?

GNU/Linux is totally different from Windows so a "PrimoCache for Linux" would effectively be a new product, which would then have to offer support for multiple GUIs (KDE, Gnome, ICEwm, Enlightenment) and potentially interact with multiple file systems (Ext 2/3/4, ReiserFS, ZFS). In additio...

Re: New Purchase Questions

eBoostr has similar licensing restrictions but is also not currently developed (the most recent version, 4.5, was released in 2012). It doesn't offer many of PrimoCache's configuration options (cache block size, read/write settings, pre-fetch/delay write for the RAM cache) though it does allow you t...

Re: New Purchase Questions

Welcome to the forums Cpjet64, Enmotus Fuzedrive looks very similar to PrimoCache's L2 cache feature (which uses an SSD to store most frequently used data from an HDD) - PrimoCache also offers a L1 cache where RAM is used to cache SSD/HDD data for faster performance still (this does duplicate Window...

Re: Advice please

...How do you Trim without it? Virtually all SSDs do background processing, clearing out erased data. I've run a RAID array for several years on Windows XP (which has no TRIM support) using SSDs purchased back in 2011 (Crucial C300s and Samsung 470s) without any noticeable loss in performance. You ...

Re: Advice please

I have 4 SSD's, 3 are for storage,backups etc and rarely used, 15GB ram... You may wish to consider HDDs for backups and other content where speed of access is not important (media files, downloads, etc). I would then suggest setting up the 2 tb970s as a RAID-0 array (if your motherboard supports i...

Re: Tiered L2 Cache

NVME is around 3X faster at random I/O. So there is an extra snappiness to be had from caching a SATA SSD on a good NVME SSD. 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 ta...

Re: Advice please

Welcome to the forums Meditek, If all your disks are SSD (which your posted specification suggests) then there is no point in using L2 caching - this is only intended to speed up HDD performance. In your case, only L1 caching is worth experimenting with, and only if you have plenty of memory to spar...
