NVELO offers two Dataplex options for use in client computing. For 
professional video and graphics production, software development, CAD/CAM, 
and gaming, Dataplex utilizes a “Write-Back” caching policy to deliver 
maximum performance and endurance for heavy end-user workloads. In this 
mode, both system Reads and Writes are cached, and the ideal MLC or 
SLC-based cache SSD would typically be in the range of 32GB to 128GB 
depending upon specific use cases.

For notebooks and tablet computing, Dataplex uses a “Write-Around” caching 
policy which caches system Reads, and can utilize MLC-based SSD’s with as 
little as 16GB capacity for cost reduction, while still delivering 4-5x 
performance over HDD’s, and maintaining multi-year endurance requirements.

Nu kiek skaitau pas juos niekur nerandu apie write cache.

"The solution intelligently places, or "caches", the most frequently needed
files (active data) on the SSD and leaves less frequently used files
(inactive data) on the hard drive."
