Caching in with SSDs

One of the most exciting features in QTS 4.x is the new SSD cache feature. This feature is not found on the Home / SOHO products, but I know many would love to see it ported over.

After selecting the Create button, we click on an SSD from the menu. The NAS that have this feature can only use preselected slots. In the TS-EC1279U-RP, it's ports four and five. There are two algorithm options, LRU, and FIFO.

The data on your cache SSD gets deleted, so be sure to clear it first.

After accepting, we return back to the Cache Acceleration page, and the cache option is new enabled. At this point, we are not caching any volumes though. The Cache Settings tab at the top lets us choose volumes to cache.

Here we see the two volumes we've created, and now we can choose to accelerate them.

The volumes are now listed on the page.
