Editor's Suggestion - Synology NAS Black Friday Deals 2021

If you truly think that you won’t need more than two-bays, either option is fine, with a slight nod to the DS720+. With that said, if you want redundancy, you’re stuck with RAID 1 or buying an expansion unit (which costs enough to warrant buying a NAS with more drive bay’s up-front). Keep in mind that an expansion unit is only an option with the DS720+.

Four-bay NAS Devices

CPU: Intel Celeron J4025

1Gb RJ-45 Port: 2

Editor's Suggestion - Synology NAS Black Friday Deals 2021

If your budget allows, the DS920+ is the four-bay NAS you should purchase. The DS420+ comes with a slightly inferior processor and only 2GB of memory. The additional 2GB of memory and better processor warrants the slight increase in price over the DS420+. Another important point to note is that you can expand the DS920+ to nine total drives if you add a DX517 expansion unit.

Five-bay NAS Device

Synology DS1520+

CPU: Intel Celeron J4125
Memory: 8GB DDR4 non-ECC
Maximum Memory: 8 GB (4GB + 4GB) – preinstalled and cannot add more.
M.2 Drive Slots (used for SSD cache): 2
1Gb RJ-45 Port: 4
Warranty: 3 Years

Editor's Comments - Synology NAS Black Friday Deals 2021

The DS1520+ doesn’t have any competition unless you want to compare it to the DS1019+ that you can buy used. The DS1520+ is basically a DS920+ with 4GB of additional memory and an additional drive-bay. The memory cannot be expanded which is a downside when comparing it to older DS models, but if you didn’t have intentions of doing that, it’s a great option. Before purchasing the DS1520+, I highly suggest checking out the DS1621+ below.

Six-bay NAS Device

Synology DS1621+

CPU: AMD Ryzen V1500B
Memory: 4GB DDR4 ECC
Maximum Memory: 32 GB (16GB x 2)
M.2 Drive Slots (used for SSD cache): 2
1Gb RJ-45 Port: 4
PCIe Expansion: 1 x Gen3 x8 slot (x4 link)
Warranty: 3 Years

Editor's Comments - Synology NAS Black Friday Deals 2021

We finally have a difference! The Ryzen processor boosts better performance across the board and the DS1621+ supports ECC memory. Not only that, you can upgrade that memory to 32GB if you’d like, which is something that’s not possible for any of the other devices we’ve looked at. The power supply is also contained inside of the device (which is generally higher quality). Overall, the DS1621+ is an actual, practical upgrade from a processor/memory perspective that we haven’t seen yet with the DS220+/720+/420+/920+/1520+.

You can also add 10GbE to this device through the PCIe expansion bay, which isn’t possible with the other smaller bay units. If you’re talking purely hardware, this is the “best” one to get, with the “smallest” total drive bays. The only downside is the Intel processor in the cheaper devices will be better for video hardware transcoding. 

Eight-bay NAS Device

Synology DS1821+

CPU: AMD Ryzen V1500B
Memory: 4GB DDR4 ECC
Maximum Memory: 32 GB (16GB x 2)
M.2 Drive Slots (used for SSD cache): 2
1Gb RJ-45 Port: 4
PCIe Expansion: 1 x Gen3 x8 slot (x4 link)
Warranty: 3 Years

The DS1821+ is practically identical to the DS1621+, but comes with two additional drive bays. If you’re in the market for an eight-bay unit, this is the one you want to purchase.

Synology DS1621xs+

I left this for last since it’s overkill for 99% of people who are looking to purchase a consumer NAS. Plus, this falls more into the “prosumer/enthusiast” category, but if you check out any of the tutorials on this site, you might have bigger plans for your NAS so a more powerful device might be desirable.

CPU: Intel Xeon D-1527
Memory: 8GB DDR4 ECC
Maximum Memory: 32 GB (16GB x 2)
M.2 Drive Slots (used for SSD cache): 2
1Gb RJ-45 Port: 2
10GbE RJ-45 Port: 1
PCIe Expansion: 1 x Gen3 x8 slot (x8 link)
5 Year Warranty

Editor's Comments - Synology NAS Black Friday Deals 2021

This is the most “powerful” consumer/prosumer NAS you can purchase in desktop form. The biggest draw is 10GbE support out of the box, but this can be added to either the DS1621+ or DS1821+ models for a reasonable price. Overall, it’s hard to recommend this model, but if you “need to have the best” and don’t want to go with a rack-mounted model, this is the one.

NAS Hard Drive Selection

It’s very important to purchase the correct hard drives for your new NAS. Since NAS devices run 24/7, you need to ensure that you purchase equipment that’s reliable.
