The feature was introduced in version 4. A cache disk is a hard drive that is not part of the normal parity-protected array. You may read data from or write data to the cache share just as you would any other disk share. As the cache disk is outside of the parity-protected array, writes will be much faster, but of course if this disk fails, all its data may be lost.
The real power of a cache disk is realized when User Shares are enabled. Hence any object — a file or directory - created on a user share is created on the cache disk provided that enough space is available. Therefore, when you browse the files on a user share, the listings will transparently include objects on the cache disk as well as those on the other data disks.
The default schedule is to wake up at AM every day. As there is a lag between the time objects are created on the cache disk, and when they are moved to the array, it may be desirable to disable the cache disk for certain shares. Each user share therefore has the option to disable the use of the cache disk for that share.
This section is present on the Share Settings page when user shares are enabled, and a cache disk is present and formatted. If there is less than this amount of free space then the object will be created on the array instead.
The emphasis here is on 'perceived'. The real, behind-the-scenes write speed of your unRAID server is unchanged by the addition of a cache drive. A cache drive simply grants you the fastest transfer that your hardware will allow by deferring the inevitable parity calculation until a later time am server time, by default.
How much of a write speed improvement can you expect to see from using a cache drive? That depends on your hardware. Slower hardware will of course result in slower transfer speeds. Everything not in the cache takes a hit. Testing method make sense to me. Great article, but what about write performance?

Step 4: Tap the Enable acceleration option under the Status or Accelerate menu.
Step 6: Choose the size from the SSD to allocate as cache memory. The rest of the SSD space can be used for storing data.
Step 8: Choose either the Enhanced mode or the Maximized mode based on your demand. Step 9: Click OK and follow the prompted instruction to finish the process.

Tip: The cache is hardware or software memory that is used to store the regularly used data and then you can access the data easily and quickly. Do SSD drives fail? Here is a full analysis on SSD technology. Moreover, these volumes are not accessible or shown up in the user interface. But they are counted in the total number of volumes allowed in the storage array.

Note: When the capacity of the SSD exceeds GB, you will receive a message stating that the rest space can be used as a normal drive. Tip: The Enhanced mode write-through optimizes data protection. If you are not sure, pick the Enhanced mode.
