As such, we populated the Synology DS1821+ (a strong performing 8-bay SMB NAS) with eight WD Gold 22TB drives and put it through our usual gauntlet of tests. Overall, we saw great throughput results across all of our benchmarking, especially when configured with the iSCSI protocol. That amount is enough for general usage, but a memory upgrade is a must if you want to get the most out of the server. Synology hardware upgrades: Here's my new Synology DS1821+ and the upgrade parts, including a 10Gbps PCIe add-on card, a 32GB DDR4 RAM kit, and two 1.92GB Seagate IronWolf NVMe SSDs.

The DS1821+ provides 8 drive bays with the option to expand to 18 using two DX517 expansion units 4. Powered by Synology DiskStation Manager (DSM), in addition to JBOD/RAID0/1/5/6/10, Synology Hybrid Raid (SHR) allows users to create arrays using odd-sized drives while still maximizing the storage potential of the array. This enables older drives to be serviceable, without requiring an upfront commitment to only installing drives of the same capacity.DSM also provides easy means of upgrading storage capacity after the device has been set up. Add in a new drive and expand your array effortlessly, without disruptions to services or requiring lengthy manual processes 5. RAID options can similarly be upgraded, from a lower-protection level to a higher one, such as from SHR-1, one drive redundancy, to SHR-2, two drive redundancy 6.

For standard deviation, the WD Gold recorded 611.48ms read and 333.9ms write in SMB, and 51.12ms read and 165.22ms write in iSCSI. The Synology DiskStation DS1821+ is an 8-bay NAS solution designed for SMBs looking for an effective way to store and protect their data. Like others from the line, this 8-bay NAS solution features an AMD Ryzen CPU and two M.2 2280 slots for NVMe Cache, which helps to drive its solid performance. Businesses can also significantly increase the capacity of the DS1821+ using dual DX517 expansion devices, which ups the drive count to 18 for a maximum single volume size of 108TB.There are certainly exceptions to this (like when DSM 7 was first released) where you might not want to be first to update. However, as time goes on, you will notice that you connect to your NAS less frequently than you initially did, and this is where I believe automatic updates add value.

The Synology DS1821+ is equipped with pretty much the exact same connectivity ports as the 6-bay model; that is, four RJ-45 1GbE LAN ports, two eSATA ports, and four USB 3.2 Gen 1 ports (one more than the DS1621+). Those who want to get the most out of the DS1821+ can utilize its PCIe Gen3 x8 slot (x4 link), which is used to add a 10GbE network adapter card or an additional M.2 NVMe drive slot to further improve performance. While the DS1621+ has a high-performing Intel-based version with the DS1621xs+, the DS1821+ is currently the only model in the line. Next we need to access the memory bays of the Synology DS1821+ NAS. These are located at the base of the device and require you to unscrew two Phillips head screws, then removing the metal panel. The second option is the least expensive but is good enough for most cases. Synology DS1821+ vs DS1621+: Here are my servers upgraded to 10Gbps using two different dual PCIe cards. With that, let's proceed with the upgrade. For this post, I did the upgrades on a DS1821+, but the processes and parts are the same on a DS1621+. Synology DS1821+: RAM upgrade After that, you can install them via the slot on the server's underside. The process is easy and painless. All you need is a small Philip-head screwdriver.
