It has been a while since I've gotten a new NAS system, and I am totally impressed with this unit. It has been almost totally painless. Now all the computers at my house can have plenty of backup storage, and easily share all the data, video, photo, and music files you are likely to have.
MY ENVIRONMENT
I am a Computer Engineer - been in the field for 35 years, so I'm fussy about my hardware. I have a house hardwired with CAT5 plus a WiFi router. The main machines are Macs, but there are some Windows computers too. This unit supports Time Machine - and the support works perfectly and painlessly. I also have a couple of DLNA media devices, so that is an important feature. The ReadyNAS also lets you plugin USB drives and they instantly become available on the network as well - so all my old external USB drives are not useless with this upgrade.
THE GOOD (Great, actually)
* This device is as close to plug and play as I've seen in a long time. There is a somewhat lengthy setup - but we're dealing with Terabytes of disk space that has to get organized and set up properly for the X-RAID striping.
* You can plug in new drives to expand capacity as needed.
* Works seamlessly on a mixed Mac/Windows/DLNA media environment
* Redundant storage keeps going even after a single disk failure. I feel all my photos and videos are now safe (although I still keep an extra off-site backup, just in case.)
* Fast - almost as fast as a directly connected USB, but now available to all the computers in the house.
* Can install extra software to securely access your data from the web anywhere.
THE LESS THAN GOOD
* There is a setting on the Network Interfaces called MTU. The default setting didn't work quite right for Macs - changing it to 1492 fixed things. But a call to NETGEAR's support actually solved the issue, so I'd rate their support very good.
* Not cheap - but I've spent years generating all my video, photos, and music - and I think the easy interface to this all is worth the price.
* The concept of 'Shares' is not really explained as well as I would have liked.WHICH UNIT TO GET?
I decided I would spend a bit more for this unit - it is the latest technology - over the older NETGEAR units. I decided the 4 disk unit and single core unit would probably have the best cost/benefit ration. With this unit, using Western Digital 2 TB Caviar Green SATA Intellipower 64 MB Cache Bulk/OEM Desktop Hard Drive WD20EARS (they seem to work flawlessly so far - even though the aren't yet on the compatibility list for this unit), you can get up to 6TB of redundant storage (recovers from a single drive failure). I'd guess they will eventually support 3 to 4 TB drives.

Netgear ReadyNAS Ultra 6 Plus (Diskless) Network Attached Storage RNDP600U Review

Netgear ReadyNAS Ultra 6 Plus (Diskless) Network Attached Storage RNDP600U
Average Reviews:

(More customer reviews)
My first NAS and I like it. I considered building one from scratch but I spend enough time doing that with my PC. I chose the ReadyNAS because it can back up my PC as well as remote backup family members (PC & Mac), has support for Squeezebox (used by my two Logitech Squeezebox Touch devices), TiVo support (useless unless DirecTV releases their promised TiVo DVR to replace their lame custom DVR). I picked the 6 bay one so I can start with 2 x Seagate Constellation ES 2 TB 7200RPM SATA 3Gb/s 64 MB Cache 3.5 Inch Internal Hard Drive ST32000644NS - Bare Drive now and then add larger drives later as I need them and HDD capacities increase.
This review is a work in progress until the Ultra 6 Plus does everything I need it to do.
MAJOR LESSON LEARNED: Make sure you pick hard drives that are on the compatibility list:[...]
I did make a mistake with my first two drives I got at the same time I pre ordered the ReadyNAS Ultra 6 Plus. Apparently Western Digital 2 TB Caviar Green SATA Intellipower 64 MB Cache Bulk/OEM Desktop Hard Drive WD20EARS are not on the supported hardware list on the Netgear site. Sux, I wish I had noticed that during the day or two of research I did into NAS boxes. Maybe they need a simple how to buy guide that includes a link to the hcl list instead of springing it on you when the device arrives.Installation:
1) You open the front cover, pop out some HDD enclosures (no tools needed) attach the drives to them using supplied screws (small philips needed) and slide them back in.
2) Attach power cord, hook up 1-2 ethernet ports.
3) Power up and during the 10 mins or so it formats the drives you install from a CD the RAIDar software to control the box.
4) Follow the RAIDar setup wizard, add some shares, change password, add self as a user.
5) Plug in APC 900VA 120V Backup-UPS XS900 (BX900) usb monitoring cable. It recognizes it and can even display an estimated remaining time left for it.
6) Update to RAIDiator 4.2.15 (x86) which updates the box firmware.
7) Coffee time as it spends about 5-6 hours doing stuff including syncing.
Everything is simplicity itself and shares are visible from the PC.Problem:
The non-compatible drives did indeed not work. The ReadyNAS forums contain instructions to use "wdiddle3" to diddle the drives into working. This seems bad because you are disabling a feature on the drive you paid for and anecdotal evidence of it working seems inadequate. Instead I am upgrading to a pair of Seagate Constellation ES 2 TB 7200RPM SATA 3Gb/s 64 MB Cache 3.5 Inch Internal Hard Drive ST32000644NS - Bare Drive. Way more expensive but they have 5 year warranties and better MTBF. As someone pointed out on the forums, the extra drive cost is insignificant compared to the cost of retrieving data off of failed drives. While I wait for these to ship I am up and running with a pair of Western Digital 2 TB Caviar Black SATA 7200 RPM 64 MB Cache Bulk/OEM Desktop Hard Drive WD2001FASS drives from Fryes, which are identical to the constellations but lacking some vibration control features. Hopefully ReadyNAS will add more of the cheap WD Green line to the compatibility list.
One day I need to do the math of cheap RAID drives vs expensive RAED drives and the MTBF implications. RAED (Redundant Array of Expensive Disks) is: harsh on the pocket book; not in the spirit of RAID; not a real word.Remote Access:
The ReadyNAS Remote software is quite nice for accessing from a remote location. Basically you install, follow a simple wizard, supply it with your email address and a user name. This gets stored on a NetGear server (I assume), since it takes about 5 minutes or so to become available. At that point, using the ReadyNAS web interface, you look up the email address and assign that person access and file space. They now have access and can mount folders they have access to. The email rigmarole is to get around needing the ReadyNAS on a static ip. In a couple of years after the ipv6 switch this kind of thing will no longer be necessary.
The process is simple when following the web documentation. Confusing if you do not RTFM. I like UI to be explorable, needing docs means the UI is flawed imo. Still you can get the job done if you do in fact read the manual. The registration delay of the email address is also confusing as it makes it seem like it is not working.
I did not fully explore the remote aspects yet for PC as the connection I was on (at&t premium dsl, prolly 4Mbps down / 128KBs up) was flaky as hell. Write speeds to the Readynas ranged from an acceptable +/- 75 Kbps one day to 15 Kbps the next. By the next time I try this it will be a Charter cable modem with 50Mbps down / 5 Mbps up. That should eliminate network performance from the equation. Sigh, if only Verizon did not stop rolling out Fios.
The process worked quite easily from a friend's Mac. There is support for time machine if you have a Mac on the local network. I do not know if it is feasible over the internet.
Having the ReadyNAS on a static ip made all this remote work easy as I could get to the admin page remotely.Backup:
The install CD contains 3 licenses for "Memeo Pro". This is sketchy as there are no recent reviews for them and the ones from 2008 are terrible. Filled with misgivings I bailed on it. I do not know why Memeo is bundled. It does not show up on any of the many backup software reviews I went through.
Instead I am using the built in Windows 7 backup to store the entire system image and all files and followed directions to save my encryption certificates as well. This should enable a full system restore. Additionally for the media folder I am using Microsoft's free SyncToy 2.1(x64) to mirror the media on my PC. This way I, and iTunes, can muck around on my PC and then sync to the ReadyNAS so SqueezeBox can play my music.
If I had to use paid backup software I would likely choose something like True Image Home 2011 Plus or Symantec Norton Ghost 15.0 (1 PC).Raid:
Regular raid modes 0/1/5/6 are supported. The default is a proprietary X-RAID2. X-RAID2 lets you replace or add a drive at any time and then repeat after the sync completes. The web site has a good animation that explores how it works. It also allows you to run with 1 or 2 disk redundancy. I think this implies a performance hit as this is not a hardware accelerated function. The flexibility you get makes it worth it in my opinion.Squeezebox:
Upgrading to the latest SqueezeCenter server software is easy and straightforward by following instructions on the web. After upgrading, a few management settings are all that is required to get the server running. Voila, NAS based music streaming. Performance seems fine on the 133 GB of music I have ripped so far. However I need to go back and separate out the cover art into a folder.jpg file for each CD folder. This would add more overhead, if only when scanning. More on that later.Performance:
I used Iometer to run some local tests with the ReadyNAS Ultra 6 Plus on a network mapped drive. Sequential writes were about 83 Mbps, reads were 41 Mbps. This is with no performance tuning like using jumbo frames, teaming both network connections, etc. Sadly my NIC does not support jumbo frames and teaming is impractical since I have only a single ethernet port on the PC motherboard. More after I buy some gear to support this.
Opening up the share in explorer and dragging some files (3GB music folders) to and from it has windows reporting 55 Mbps (maybe my own drives are slow or only 5400rpm vs 7200rpm for the Constellations). The initial rates range up to 80 - 90 Mbps and then drop over time. That seems to indicate initial caching effects skewing the average.
The highest rate I saw so far was 155 Mbps, for syncing operations on the NAS itself.
The read speed being half the write speed is weird. I would expect read to be double the speed due to dual disk redundancy. However I am using a proprietary ReadyNAS "X-RAID2" mode that allows easy 1 disk at a time expansion / replacement which may just not behave as I would expect.Networking:
The NAS has two gigabit ethernet ports. They can be teamed to provide increased throughput and fail over redundancy (assuming your router / switch supports it).Impressions:
* Noise. On boot up it is extremely loud. 70 - 80 decibels. After a few minutes it settles down to

Synology DiskStation 2-Bay (Diskless) Network Attached Storage DS211J (White) Review

This thing is fast/scalable/reliable/configurable/expandable/bulletproof and worth ten times what it costs. For the money you get a full function NAS with two drive bays, Linux OS with plenty of really top shelf apps, support for raid arrays and JBOD, thru-the-internet accessability, dlna media server, audio and video apps, excellent disk management apps, solid group/user creation and mgmt, a web server app, ddns with 'no-ip' support and a host of other very useful file/data sharing utilities. Call Synology tech spt and you won't get a tier-1 zombie - rather you get a very knowledgeable competent tech who knows the product inside and out - very impressed! I've used most of the network apps and so far they work perfectly.
Cons: This is not a con but be advised: if you're populating the NAS with large drives (I populated my NAS with two, 2TB drives for a max capacity of 4TB), initial drive preperation will take 8-10 hours to complete - for each drive! I called Synology tech spt to find out if there might be a problem and they explained that the NAS drive prep utility goes thru an excruciatingly detailed surface scan at the outset thereby eliminating issues with bad sectors and other related problems once the drive is placed into operation. THere is a less time consuming drive prep offering but they recommended the full scan - and so do I. Find something else to do while the scan is running. Also; I bought my NAS to use primarily as a DLNA media streamer. It does that flawlessly - this thing is bulletproof, I have purposely tried to add and delete shares/folders/users/etc etc to try and confuse this box. It continues to operate flawlessly - I'm amazed and impressed! The Synology folks surely did their homework.
Other Thoughts: There is one anomaly I found with the DLNA function that I find rather annoying; Once the DLNA server is activated in the command interface, it creates three separate media folders (Audio and Video and Photo) and places them at the root level of Volume 1 (ie disk 1). The DLNA server will only look into these folders to find media to serve up. So, unless you Raid-0 your two drives and create one large volume, you will be stuck storing all your media files on only one drive - OR WILL YOU. There are several workarounds for this, and they work (although a little cumbersome). Once the three media folders have been placed on your vol 1, you can manually move one or more of them to vol2 and the op sys will work just as effectively with the folder on vol 2. You can also use a 'root' login to access the linux opsys and mount pointers to other shares you've created on vol2. Both techniques are explained on the Synology website. Maybe an update to DLNA file structure and searching is due Synology(hint hint).
Network streaming speed is more than ample. I have the NAS attached to a gig switch which is then attached (gig enet uplink) to a Linksys 3000 gateway. As a network bandwidth and NAS performance test I have run the following: one HD video stream to Samsung dlna enabled TV -and- one HD video stream to second TV using HP DLNA-enabled client -and- one audio stream to my Iphone (Wireless) -and- a second audio stream to my dlna-enabled V-Tech radio (also Wireless), all streams were running concurrently without any hesitation, skipping, pauses or any other anomalies. THis, plus all the other very useful functions make this box a real keeper!
