Upload your Previous Configuration This is the same thing that cache memory does: The size of the cache is not added to the size of the DRAM, it’s simply invisible. In either case the faster medium (the DRAM in this case) temporarily stores data that it copied from the slower medium (the Optane DIMM in this case) and the cache controller manages the data’s placement in a way that makes it appear that the Optane DIMM is as fast as the DRAM. Mar 23, 2016 · Jesus. PrimoCache resets the cache on every little tiny sneeze of the system and VeloSSD seems entirely bugged from the get go. I know how to use fucking google and all I got was tons of stupid RAM caching stuff and bunch of "SSD caching software" that got bought out years ago by Samsung and other big companies. The consequences of this architectural decison are:-. less hardware in the SSD card - so much better intrinsic MTBF and potentially the lowest cost to build product. easier to control end to end data integrity. faster access to flash data by wrap around software APIs. vm.swappiness=1 vm.vfs_cache_pressure=50 The first setting prevents disk cache (e.g. doing cp) from swapping out existing apps from RAM. The normal default setting on that is 60. Note that using 0, although more aggressive, has been sometimes reported to generate out-of-memory errors.

Sep 27, 2019 · Wrong. If your computer has a solid-state drive that says it can handle hardware encryption, BitLocker doesn’t do anything at all. BitLocker just trusts the SSD to encrypt your files, abandoning all responsibility. And, as researchers have found, SSD manufacturers are having some serious trouble implementing encryption properly. can dramatically reduce the amount of read cache needed for storage control - lers since the server-side caching engine is handling all reads. This frees the read controller cache for use with non-accelerated workloads. In addition, a high read cache hit rate on a storage controller is usually an indicator of good
