This review is from : Synology 5-Bay Plug-n-Use Expansion Unit to DS1010+, DS710+, and DS1511+ Network Attached Storage DX510 (Black)
Very well made Everyone should upgrade to DSM 3.2 . **IMPORTANT UPDATE**OCTOBER 2011 synology has now got dsm (the o/s) 3.2 out of beta and it rocks! it has a built in torrent downloader! I swear there is nothing this system can not do - it runs my websites, my torrent file transfers, my house media service to my samsung tv set (had to upgrade the house to gig-e) - every synology customer who can should switch to dsm 3.2 - you will really like your box. Also I ordered the ~24 memory amazon recommended and upgraded my ds1010 today so it now has 3GB of ram. It never uses more than about 3% of the ram (2GB ram cache file on disk). For a visual see my photo uploaded above. Original review below
=======The present version of synology's o/s supports 16TB (after applying the raid loss) volumes. What's a volume? It's a raid or no-raid group of disk drives that is combined inside. A stock 1010+ will let you combine 5 ea 2TB (really 1.82 TB) disks to end up with a 9.1 TB volume (which meets the OS limits of 16TB) but when you go to expand it with this unit, you have 10 drives instead of 5 and a 18.2 TB volume if you allocate all drives to one volume (which is the idea - to have as many data disks and just one parity disk). Unfortunately if you went all the way with 2TB drives, you went too far and exceeded the 16TB limit, so the last disk must be left out of your raid volume (it gets 9 drives, one is a parity drive, and your data drives are 8 x 1.82 TB for 14.56 TB of data from the 8 data drives with raid5 protection). The 10th drive is leftover and can be used as a separate 1.82 gb storage volume on the network. There is a workaround, but as I learned it is best not to have your volume span 2 physical boxes in case a cable comes loose or a power cord dies. Also ALWAYS put a big UPS on the NAS and connect it with USB so the NAS can shutdown if there is an impending power failure.The other option is to make 2 raid5 volumes, each with 4 data disks and 1 parity disk. The advantage is that if the expansion box fails, only the volume on it suffers any data exposure, whereas if the expansion box fails with a volume spanning to the expansion box and the expansion box looses power or e-sata it will destroy the main volume. the e-sata cable that comes with this unis has 2 screws that hold it in place, and a ups is highly advised)Either way you loose 2 drives in a 10 drive system - with a 14.56TB volume you loose drive 10 to be just a plain old 1.82 GB disk drive, with 2 separate volumes, you loose 2 drives to parity storage.For more detail on using the 1010+ see my comments posted below - If I just wanted a big raid, in retrospect, I'd consider their 8 drive rackmount version (which would give me 7 data disks in raid5 or 6 data disks in raid6). The reason is it avoids the 2nd power cord and the e-stata cable for the sidecar - if there is a problem with either of those and your raid spans the sidecar you loose everything fast. The 8 drive rackmount is almost 10 drives, and they have a 16 TB software limit, so with 10 disks, 1 of them becomes "just a disk" and you get 9 disks maximum in a full box + sidecar system - might as well get the enhanced reliability of the 8 drive system for that and not have a 20 inch umbilical cord between your boxes and 2 power cords.Also power draw is VERY LOW - the system implements spindown when nobody is using the raid for an hour.see my comments on the DS1010 for more info of how these are made. [note - 1010 obsolete - replaced by 1510 which can have 2 sidecars or 15 drives x 3 TB or 45TB of basic storage]The good news is that synology does release frequent firmware upgrades which are easy to install. I'll put through a request to support 32GB volumes instead of 16GB so that we can have less parity loss.

Synology 5-Bay Plug-n-Use Expansion Unit to DS1010+, DS710+, and DS1511+ Network Attached Storage DX510 (Black) Reviews
My First NAS . Synology DiskStation 5-Bay (Diskless) Scalable Network Attached Storage DS1511+ (Black)Although I am reasonably competent with PCs and Mac's, I am a neophyte when dealing with NAS units. I was a little concerned dealing with Linux or command line prompts. I also wanted a solution which was scalable, required minimal handholding for adding or replacing drives, or changing RAID configurations as the number of drives in the unit grew. My investigations kept bringing me back to the Synology line of NAS and its DSM software. I ended up going with the DS1511+ due to its five drive capacity, expandability, hot plug capability, and the most important point for me the DSM software. I ordered the system and four Hitachi 2TB drives on Friday, and they arrived Saturday afternoon (with one day delivery, a bargain with Amazon prime). The out of box experience was very good. I was easily able to load three of the Hitachi drives into the Synology (the fourth being a backup in case one of the drives has an issue in the future). I loaded the DSM software on my PC, powered up the Synology, and the software immediately found the NAS. I formatted the drives and after approximately an hour with RAID build, I was ready to start loading data onto the 1511+. I created folders and userid's, a piece of cake with the DSM software, and also enabled the TIme Machine service for the Mac machines. I then pointed the PC Windows backup and the Apple TIme Machine backups to use the Synology NAS and started complete backups of my systems. I run an E4200 802.11n wireless router, not the fastest setup in the world, however I was able to get 10MB/sec sustained transfer rates per client, with no issues running multiple clients in parallel. 16 hours later, the initial backups were complete, and incremental backups were being done on all three machines on a regular basis. Again, I have little knowledge of the command line underpinnings of the Synology unit, and the DSM software did a great job of making that knowledge unnecessary. All worked as it should. I later used the huge amount of available storage to move my Itunes library to the Synology. I then enabled the Itunes service via DSM, and voila I was now able to share Itunes throughout the entire house (via a couple of Apple TV devices). One hitch occurred however with the Apple release of the Lion operating system. I upgraded one fo the Mac's with Lion, and Time Machine no longer functioned :-(. After a couple of hours of searching on the internet, I found that DSM 3.2 Beta did support Lion. I'm normally a little leery of using Beta releases, especially when my data is involved, however, it was either that or going back to Snow Leopard, so I took the DSM 3.2 plunge. The upgrade worked flawlessly, and Time Machine was again functional with Lion. Synology could have done a better job of alerting users to this potential issue and steering them around... however, this is the only negative that I have with the unit. The DSM software is so intuitive, that I have not yet had to contact customer support.. I would like to do this over the next month just to ensure they are responsive. I did purchase an e-Sata enclosure and I am now backing up the 1511+ on a weekly basis. I also plan on procuring five 3TB drives over the next month, and will have an opportunity to test the hot plug capability and upgradability of the 1511+. Bottom line, the DSM software makes this very usable for me with minimal learning curve, so far this has been an excellent unit.

Synology 5-Bay Plug-n-Use Expansion Unit to DS1010+, DS710+, and DS1511+ Network Attached Storage DX510 (Black) Opinions
Works great with my 1511+ . Product is great, very easy to setup and technical support is even greater. Can't say enough good things about Synology. No Hiccups what so ever from purchase to setup. Extremely robust.

Does it all! . I had a windows home server and this synology blows it out of the water. Not only do I get hybridraid but I get incredible speeds. This destroys the Drobo on speed. I bought the addon DX510 and now I get the space of 9 Drives with 1 parity drive. 11TB of space. Highly Highly Recomend this device.
Great addition to DS1010+ . If this works as easy as the DS1010+ by simple connection with an external SATA connection, then this is a great addition to our NAS setup. I haven't installed the device yet since the DS1010+ is only 70% full. But based on the DS1010+ performance, I can guess we will be quite pleased with the extra space. I use the WD 2TB Green hard drives which are listed as acceptable on the Synology website and have had no issues to date.
