Re: new mainboard with 2 or 4 RAM Slots - more stable with 2 slots?

Upgrading from 2 to 4 sticks means they aren't from the same kit. It's usally recommended to but a kit because those sticks are almost identical. More identical than random sticks that seem to have identical specs. That's not claiming it will cause stability issues for sure, but if you main goal is ...

Re: Speeding up a database

http://www.romexsoftware.com/en-us/primo-ramdisk/features.html Read and understood the difference between the version. Is there any speed difference between the versions? (Assuming a 100% similar system and configuration) Will the reloading of the RAMdisk image, at Windows reboot, be complete *befor...

Speeding up a database

I'm a proud PrimoCache owner that's considering getting even more proud by buying another Romex product.... :-) I'm building a 130 million record database with 100 fields each. Lots of filtering and searching. A RAM disk should speed up things greatly I think. What scares me is data securing. A cert...

Re: What is this info mean?

The usenet software uses WinRAR in the background. I have no control over it

The only thing that may work are symbolic links. But the last time I've tried they only work on the same drive.

Re: What is this info mean?

Yes, they do from what I know. However in a much smaller volume (like 30GB out of 500GB) you have much less space to shuffle it around So wear balancing is per partition? Not disk wide? The recovery volume exists on most boot drives with Windows, I forget when it was introduced (W8 perhaps) Could b...

Re: What is this info mean?

Not sure if you knew (or if I'm understanding you correctly), but Primocache can manage multiple drives in the same Cache Task Must admit I forgot about that, but... Yeah, I use Drivepool also on a set of 9x8TB drives. I never cache my data drives (the pool) since the hit ratio on reads for such a ...

Re: What does this info mean?

If your .RAR file download was onto the temp drive, and the unpack was also there, and your deferred write time was long enough to cover the entire set of 3 operations, then you'd never see writes to the actual temp drive. Your cache size would of course, have to be large enough to hold all the RAR...

Re: What is this info mean?

Plus - you really should have a UPS on the machine if you're going to use deferred writes. You can get away with not having one and using a short delay (like 5s), but there's still a small amount of risk if the machine BSODs. You are right in case the SSD is also a system disk (it is) That's why if...
