Summary: After experiencing a crash that took away 6 months of hard labour, I decided to buy this model of NAS for my home. After installing I slowly learned that it is basically a full fledged server not only for a home but any small business. I installed 4 3TB drives and organized them in the proprietary SYNOLOGY RAID giving me 8.05 TB of one disk fail protection.
Summary: However, I researched a little more on the temp issue and the drive temps appear to be within acceptable range for these drives (a mixture of Seagate, Hitachi and WD). I also found out that it is possible to manually edit the config file of the unit to reduce the temps further if I want to.
Pros: Solid, reliable, decent performance for its class so far, comparatively very quiet, great interface, great features. Too many to list. The DSM is the best NAS OS I have ever used. Worth the extra premium for Synology products. I love how even the lowest-end products (the J series) gets the full OS treatment, and it works extremely well. If Synology keeps up the quality control of the DSM OS, I'll be a customer for years and years.
Cons: The DS413j runs a little warm compared to my ReadyNAS Ultra and other devices I have. I did not like seeing my hard drive temperatures in the 40-45C range when I first set it up during the RAID build process. Again, I also have a DS212J, ReadyNAS and other devices and the drive temps are much lower in those, usually 32-38 in my ambient environment.
Summary: - Download station doesn't have "force start" to bypass the "no download" window on the schedule and you can't adjust the download priority. (They're pretty responsive to customer feedback, so I think this will change in the future.
Pros: Get it! You may waffle as I did because it looks like a humidifier, but you'll get over that when you get this beast set up.
Cons: - It looks like a humidifier or space heater. I wished it looked like one of their lean and mean looking models. The DS413 for example (no "j").
Pros: Fast enough for home use, works great and reliable. The worst part of buying this product is finding the right drives, but that is true for all NAS devices from any vendor. Plenty of add on features that don't require being pre-installed or additional purchasing. Makes it a light weight NAS.
Cons: Manufacturer selection of approved drives is too small.
Summary: I had a Seagate Black Armour 110 NAS prior to this that I hated with a passion. The DLNA server never worked consistently and storage was capped (that was more my fault than the Seagate). This NAS is a completely different story. Simple setup if you any computer and network experience, drives install super easy and its really easy to expand your drives without having to reinitialize the whole system if you use the Synology Hybrid Raid technology.
Summary: For the average user this box is complex to setup since there is a lot of things this box can do. Parity check does take a long time to do. Overall once setup the box is very reliable. Just make sure to format any hard drives with data on them before putting them into the NAS.
Pros: Love it! Very easy to setup (after I replaced a bad WD Green drive, that is!) I have 3 500 GB drives in a RAID 5 configuration for 1TB storage. Also have a 500 GB set aside for my girls to back up to, and for a spare for the RAID, if needed.
