John R : Can you start with two drives and expand to five at a later date?
Shopper : Why Did You Choose This?Jeston M : Been looking at this for a while, the most recent 1522+ does not have all the nice features of the 1520+KERRY B : ReplacementJoshua S : I wanted to run VM's and Plex. Good storage capacity, good reviews.LEONARD L : Was going to get DS920+ but when add 4gb ram, the DS1520+ is only $50 more and it has more features and greater expandability.TRISH B : The 6 bay was not available?LEONARD L : Was going to get a DS920+ and add 4mb memory for $90. This unit is only $60 more with the 8mb plus extra bay and much more future expand ability.EMILY S : video post productionLOYAL J : As of writing, this appears to be the best way to match a DS920+ with 4x16TB; it seems to have more powerful specs and yet remain less expensive when purchased with 4x14TB Toshiba NAS and a 1x6TB WD Red Plus. Hard drive cost is an important factor in overall cost of NAS setup.MATTHEW M : Centralized storage of important documents, videos, pictures, and creative works. Personal cloud storage when away from home.WAYNE N T : Seems like the best option and value, going with wd red pro drivesWAYNE M : Seem reliableJEFF N : Enough drive bays to support multiple RAID configurations.ROBYN B : Based on recommendations from my IT guy and an article written by Improvephotography, I felt it was time to upgrade from single external drives (I have 10 2 TB drives and just had a scare where I thought I lost a full main drive!!)

Best NAS out there!

Just got an upgrade to replace the old one, I have never had a better NAS! My old unit is over 10 years old and has been stable since day one. Definite learning curve, but after having set up the first one, the second one was super easy. TONS of options, more than I'll ever use for sure.

SSD cache not created

The DS1520+ will not create an SSD cache from an installed SSD.

Great software - Good hardware

Working great so far. There is a lot to learn. This NAS can do more then I will probably ever need it for. If I had a 4k TV and 4k media to steam to it I might have gone with a DS1621+

Great unit, easy to configure and use

I started with a QNAP unit and ran into trouble. I returned it to Adriana, no problem and purchased this Synology unit. The user interface is really simple. It may not have as many knobs and switches, but it works. It?s a great unit. The only downside is no 10gbe connection.

Easiest NAS to work with but needs more for Mac!

Beautifully packed. Easy to setup. Easy to interface to cloud storage. One suggestion is to better integrate with a Mac. Time machine is supported for local but I need to backup remote Mac’s as well. Would love client software for a Mac that ensures TM works remotely. Finally I love the package but the documentation is sparse. Need to search all over just to determine what a package does.

I love Synology Products

I upgraded from the DS412+. Swapped my hard drives to the new NAS in the exact same order and everything was migrated in less than 30 seconds. Awesome product... my plex, settings, and all my files are running great.
