Please share your experiences and reviews about NAS (Network-Attached Storage) below. In particular, rate their compatibility with Macs, OS X, iTunes, Time Machine, AppleTV, and other Apple-specific tools. The goal is for future users to be able to easily find the best Mac-compatible NAS appliance.
Rules:
Also welcome: useful reference links, such as this one from xlr8yourmac.com.
The Synology DSM software has built-in support for Macs including Apple Fileshare Protocol (afp) and Time Machine support. It has an iTunes server in addition to a regular DLNA Media server. As it is Linux based it is easy to configure the NAS to do rsync backups (ssh login).
It has a great web-based desktop-style interface that is very easy to understand and use. The DSM software is constantly being updated and improved.
They have solutions from 2-disk on up to 15-disk. You can find the 4-disk DS411j without drives for less than $400.
My NAS of choice is an old Mac. In my case, I had an old MacBook that wouldn't hold a charge anymore so I rigged up an eSATA connection to my 2TB external drive.
The advantages to using an actual Mac over a true NAS system:
Further features to consider:
The Drobo FS is my new favourite NAS. I've run a Netgear ReadyNAS and a PC-based NAS in the past and neither touch the Drobo FS for simplicity, speed and reliability. The ReadyNAS suffered from poor RAID performance, especially on reboots when volumes needed to be scanned. And the power supply in it was really lame. And the PC-based NAS was just a pain to maintain and costly to keep up.
The Drobo FS is super simple to set up. Has very, very good volume build and scanning speeds on startup. Has what has to be the best hot-swapping of any multi-disk unit I've ever seen that was in the sub-$10k range. And performs like a champ while drawing very little power.
I now run an FS for home sharing and an old Drobo hangs off my iMac for audio project data. They are teh awesome.
The Time Capsule can be used as a shared drive.
It is also a Wi-Fi router, and is automatically recognized as a backup device for Time Machine.
Freenas using generic hardware
I love the ability to grab an old computer, fill it full of cheap hard drives, and install Freenas on a CF card or USB drive. Software RAID is reliable.
A key point, if any of the hardware dies, the RAID array can be rebuilt when the software is installed on new hardware, unlike some proprietary solutions (NAS or RAID cards) where you may be tied to a particular vendor and/or model, which, after time, may not be sold/available.
Works fine with Macs and PCs -- and for this reason i use SMB shares rather than AFP. Performance is fine.
I use the SMB shares to stream to all the computers in the house, and there is no problem.
Time Machine backups are a little more complex, involving creating a Sparse Bundle (which is not the official method). For this reason, i don't do this, i use Carbon Copy Cloner to run to a disk image (dmg) every night.
I use MediaRover to sync iTunes libraries, and this works fine. Other iTunes support is available (an iTunes/DAAP server called Firefly), but i haven't used it.
It has a BitTorrent server built in, but again, i haven't used it.
Administration is very easy (web based), setup is not difficult, but there are several steps to add disks, format them, create a RAID array, create a mount point, enable the services (AFP or SMB) to access. Documentation and community support are satisfactory.
Don't want start any flamewar, but today here is only NAS solution - the ZFS based NAS.
ZFS is a filesystem, what has "copy on write" feature, so you will get a backup in every save - fully transparently. ZFS has million really cool features like raid management, snapshots etc.. too much for one post. If you interested can duckduck for ZFS.
ZFS is implemented in Solaris and in the FreeBSD. So, you can:
You should definitely check theese:
We recently joined the crowd getting their first NAS, and after taking a close look at several, settled on the Netgear ReadyNAS NV+.
The Drobo, previously mentioned, was tempting—but just way too expensive for use on a home network.
We've only had it a month or two, but so far, so good. Like most Netgear products, it works well with Macs. There's also a solid community & support site.
Yesterday I installed a Western Digital MyBook World Edition, 1 TeraByte, single disk.
Pros: very simple to install and work with, includes a Media Server and a iTunes server that can be used to share music and videos across the network. It's pre configured with the common shares and if you copy the files in the proper folders it's very, very simple to use. Quite cheap compared to a similar solution from QNap or Sinology. I did not perform any single task "mac related" on it and it worked from start with my Mac.
Cons: old firmware from 2009 and no update available, the single 1 TB disk inside obviously do not support any kind of Raid, no serviceable by changing disk if needed (unless you broke your warranty), the control panel do not give you a lot of control also if you use the so called advanced version.
Definitively a good choice for a "first" NAS to work and experience with, if you need to go on a cheap model or if you do not have a lot of IT experience, suggested for simple home environment where no redundancy it's needed, I would avoid it if you need redundancy or if you like to fine tune and experiment with every possible option.
There is also a public wiki about hacking it but I've not tested any of the stuff described (yet!).
UPDATE: after some time I've found more problems, all related to the time machine interface: 1) The quota option do not work with time machine 2) The Lion update completely stopped the Time Machine usage
NOT RECOMMENDED ANYMORE!!!!
UPDATE: The Lion/Time Machine problem will hopefully be fixed soon. Apple changed some things and Western Digital is working on an update. This affects the MyBook Live and MyBook World Edition II.

The Qnap TS259Pro+ which uses a 1.8Ghz Dual Core Atom CPU, would be the perfect setup for Sickbeard, and streaming to more than one TV in the house. Take the firmware for a spin with this "Live Demo"
At the moment of buying, the features listed sounded great, and Mac compatible.
Once in the studio, and after 4 weeks, it is just a hard drive on the network.
These are some of the issues:
Stay away, not only mac users, but everybody who wants a NAS, this is not an option.
The D-Link DNS-323 is quite customizable, but should do everything you need out of the box.
It has a very active community behind it
QNAP is surprisingly perfect actually ;o) I use TS-419 for my home use and pretty happy with it.
I put together a comparison here: http://forum.railsonmaui.com/t/best-way-to-backup-large-external-hard-drives/305.
Based on reading many of the numerous reviews, the WD gets the job done at a very competitive price point with few disadvantages.
I'm ordering one this week and will plan to update my answer. I'll be using it for other network backup and shared network files.
