Easy setup, great management interface, 4 gigabit nics are excellent

This is a fantastic NAS device with great performance...as long as you stay within it's abilities.

I have since moved my Plex server to an ESXi-based system with the Synology acting as the VM datastore and the performance is excellent.

I was worried I wouldn't notice enough improvement for the cost---esp. since I didn't have any real issues with the 1512 (other than hoping for better performance)

I just loved the quality and performance, the interface.

Synology technical support leaves a LOT to be desired and must improve as they are shipping and designing larger and larger NAS units

C2538 *Device stopped working suddenly, and cannot be booted up again, ever

These devices are superb and do everything I want them to do without complaint

This NAS has exceeded all my expectations

It has been super stable and also totally exceeded my expectations

(and the “option” of doing 10G networking, in the future, if needed [with the PCI slot available

To do that, however, you need to replace the existing 2GB RAM module with a 8GB one and add another 8 GB in the available empty slot.

You can add 4 GB in the available slot, to bring it to 6 GB total.

That being said, this unit makes a great backup unit, or is just fine if all you care about is 12 bays for really big storage, at the cost of much lower performance.

When that happens (typically any time after the first year of use), the motherboard is bricked, which means the entire unit is dead

I would definitely buy this unit again and I highly recommend it.

The unit itself is so much easier to use than my QNAP, you don't need screws or anything to hold the drives in the bays, the speed and responsiveness is very fast!!I'm very happy with my purchase!

Excellent unit, with the large NAS Enterprise drives, it really smokes!

I wish I had listened to the other reviews that say, good product, awful support.

Great reliable storage from a respectable and earnest company with wonderful support!

The other benefits that I see over other brands is the supports and comprehensive apps available.

The other great features include the ability to upgrade the RAM and use an SSD for dish cache in the standard 3.5 inch disk slots.

The Cloud Sync backup feature is perfect.

Before you buy this unit, you may not know about its super-quick cousin the DS3617xs (looks exactly the same); which has low-end but still Xeon processor, 16GB ECC (correcting) RAM expandable to 48GB!, and so fast it can utilize two (2) of the 10Gig Ethernet ports if you addon a compatible 10G NIC at blazing speeds

, I AM happy 😃 so far with this product (about 80%)It is WAY better than the Drobo EVER was, and the data transfer (so far, about 70% complete) is going very smoothly (THANK GOD!!!😜🎉👍🏼)I thought that USB3 to/through Ethernet (1G) would be slow?!

I've only had this thing for a month, so I've barely scratched the surface of its capabilities.

But this thing is rock solid, and has a ton of additional features.

I'm finding this thing to be so much easier with AudioStation to get songs in to my iPhone rather than iTunes which tends to slow down over time when it gets loaded down with lots of content.

Synology has an unbelievable product

I wish I had listened to the other reviews that say, good product, awful support.

working as expected no issues noted good product

The issue being a known bug just makes it worse

Zero issues, works like a charm!

worked fine the other 1 x 4 had issues

Seems like I was always having issues with the drobo.

I have a real and serious issue, I have data at risk, and Synology answers are evading their real issues and trying to put more weight on my end as a customer

I removed the hard drives from the old unit, and put them in the new one

I had built a storage server using LSI raid controller with many hard drives.

These are very reliable (with the right drives, anyway--I now use HGST Deskstar

I use it primarily as a file server, and it replaced several external hard drives

It's expensive up-front, but it allows me to buy hard drives in smaller capacities
