Reviewing the Synology DS1817+ with M2D17

Configuring the SSD Cache

For those who are new to SSD cache just like me, the process of creating SSD cache is just a matter of following the Synology SSD Cache Creation Wizard.

There is also a SSD Cache statistics dashboard to view the status of the cache usage and hit rate.

Let’s create a SSD cache. It is created via the Storage Manager.

Since we have got two SSDs, let’s create a read-write cache.

Using both the Samsung 850 EVO and WD Blue for the read-write cache.

For SSD read-write cache, you will need two SSDs in RAID 1 configuration.

    i’ve been looking at upgraded NAS offerings. this seems like a great choice, my workflows are mostly IOPS limited, so this would represent a significant increase in performance and a significant decrease in keyboard smashing stress.

    Good review. Do you know if it possible to use an M.2 SSD installed in the M2D17 card as an extra storage device? Such as using it to run all your app’s etc (docker, virtual machines…) instead of running them off the array. I currently use slot 8 with an SSD installed for this purpose

    Hi Darren,

    Unfortunately, we can’t use the SSD on the M2D17 as storage volume. It will just appear as SSD cache.
