PrimoCache

What is PrimoCache?

PrimoCache is a software-based caching solution that enhances system performance by transparently storing frequently accessed data in memory. It cooperates with the system's memory to provide data caching for disks, enabling faster retrieval of requested data. Unlike the Windows cache manager, which caches on a virtual block basis (within files), PrimoCache caches data on a logical block basis (within disk offsets) One of PrimoCache's key components is a storage class filter driver that resides in the storage stack, intercepting I/O requests for data on disk. If the requested data is already present in the cache, it can be served directly from memory, which is significantly faster than fetching it from the disk PrimoCache offers a range of features to optimize system performance, including support for various caching algorithms, such as Least Recently Used (LRU) and Least Frequently Used (LFU). It also provides flexible caching strategies, including Read/Write Caching, Read-Only Caching, and Write-Only Caching. The software supports both Write-Through and Write-Deferred modes, as well as the utilization of OS Invisible Memory, which can be leveraged on 32-bit Windows systems with 4GB or more of installed memory Additionally, PrimoCache supports the use of Solid-State Drives (SSDs) as a Level-II cache, enabling tiered caching for enhanced performance. It also offers persistent caching, allowing cached data to be retained across system reboots. The software is compatible with multiple volumes, NTFS junction points, and various disk types, including basic and dynamic disks
