Reviewing the Synology DS1817+ with M2D17

The souped-up DS1817+

We will be upgrading the DS1817+ to 16GB RAM and enable its SSD read-write cache.


Installing additional RAM

The DS1817+ has two (2) RAM slots and officially supports up to 16GB (dual channel). We got the Crucial 16GB RAM kit (2 x 8GB).

The RAM slots are located on the underside of the DS1817+. The RAM upgrading process is straightforward as we just have to remove a couple of screws to access the slots. Installing the new RAM modules took last than 10 minutes.

Installing the SSDs

The Synology M2D17 supports up to two (2) M.2 SSDs. We will be installing the M2D17 with Samsung EVO 850 and Western Digital Blue M.2 SSDs into the Synology DS1817+.

Installing the M2D17 requires you to remove the DS1817+’s enclosure to access the PCIe slot. Previously, this area of the Synology NAS used to be where the RAM slots are located.

Just in case you are wondering if you can use the M2D17 with SSDs as part of your regular storage volume. Nope, you cannot. You will have to tinker with the mdadm to do so and risk losing your data (plus su.

    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.
