SSD Cache

[chandc99]

Would it possible to add the feature of SSD Cache in the future firmware release?

This is a feature found on other NAS manufacturer's products. You can add an SSD to your NAS, and it will act as a cache between your network clients, and your slower mechanical-based RAID, allowing for faster writes (as they get done to the SSD, and written back to HDD later on), and faster reads (as it can actively be cacheing the most frequently accessed files on your RAID).

Would not installing more RAM in the NAS provide the same effect?

The SSD won't cause any data losses in case of a power failure before the cache gets committed to the array. Plus, the cache can be much larger than with just RAM.
