NAS devices - recommendations?

Just wondering whose products are being used by the audio community.
If you haven't found it yet, Computer Audiophile is a good forum to research the question.

Recommended NAS devices can be found here:
Thanks. I wasn't aware of the site. I'll check it out.
Qnap Nas works very well IMHO (using MinimServer as music library software).
Are you relying on RAID for redundancy, using a backup solution or both? If you're ripping from media, I assume the backup is the media. But, if you're buying files, what are folks doing to protect their investment?
RAID is not a backup. You need a separate device which is,
optimally, located (or stored) outside your home.

P.S.: I use QNAP NAS drives, too.
It's counterinturitive, but our media (e.g. CD's) are life-limited (

RAID's obviously represent an array of multiple drives which contain duplicate (backup data). If one HD has a mechanical failure, the data remains intact on another drive. However, a virus may be copied from one drive to the other before you know you have one – so all your backups may be jeopardized. Also, damage (fire, wind, water) to your home/computer (mirrored array) would leave you without a backup.

Mirrored drives make sense if you're going to be adding or changing data on a routine basis, but if you're like me, I've already accumulated most of my favorite music and my library remains fairly static – adding a few CD's now and again. This makes manually creating a duplicate drive not that difficult when those few times arise, when I need to add something new.

I maintain my music on several hard drives, some installed in my Windows PC, all the rest stored in-house or off site – don't want to lose the time spent ripping the +28K tracks that I have.

I buy internal hard drives and external docking units for internal hard drives. These docks are plug and play and most are "hot swappable". In my audio room to connect to my Mac Mini, I use one from this company:

For the hard drive to Mac mini connection used in my audio room, Firewire is (sonically) preferable, so I bought a dock with that capability. I also have a similar dock that I use for my Windows machine, only it doesn't have firewire capability, which makes it more reasonably priced (i.e. the more connections [USB, SATA, Firewire etc.] the higher the price of the dock.

BTW, if you don't need a firewire connection, a USB or SATA dock can be used on both a Windows or Apple machine.I like using USB/ESATA/Firewire hard drive docks.

My audio files are maintained as AIFF's and FLAC's. I like the latter because it is an open source CODEC and useable most everywhere. For track back-up purposes, always rip to a lossless format -- i.e. never rip to a lossly format (such as MP3).

I treasure my Tags (metadata), so although before Computer Audio, I did rip to WAV's, I no longer do so.

For multiple CODECS (i.e. WAV, AIFF, FLAC, MP3 etc.) dBpoweramp is a handy Windows based ripper and CODEC converter, because it will rip 1-CD to two different CODECS simultaneously. And it provides 3-different metadata on-line sources for comparison purposes, with an AccurateRip feature that confirms that your rip either is, or isn't identical to its database of other rips of the same CD.
I have a 6TB QNAP NAS (3TB of storage, 3TB backup), plus a completely off-site 6TB QNAP NAS located at a friend's place (automatically updated via the internet).

All of my CDs are WAV files and have tags for metadata (info about the tracks, artists, album art, etc.).

So far, I have about 4,200 CDs ripped.
I'm aware that RAID is not a backup solution. Depending on the flavor of RAID employed, one could choose to avoid a backup solution with a somewhat reduced risk of data loss. Though not every flavor of RAID provides data redundancy - in some cases you just want the performance gain of having more spindles.

Thanks to all for sharing their solutions.
Solid State Drive, still expensive, seems to be perfect for the audio. It has no moving parts while the only limitation is number of writes to each sector - small with audio (mostly reads). It is also silent.
Kijanki, are you using any redundancy or backup solution with your SS drive?

That would not be a good choice IMO, Bob, and I know Kijanki for one will say the same thing. Mrmb mentioned the possibility that RAID might not prevent data loss caused by a virus, or by physical damage resulting from fire or acts of nature. I'll add that other possible scenarios which could result in data loss include failure of the RAID array's power supply, a severe power surge, or the array's controller circuitry going berserk as a result of an undiscovered latent design defect in its hardware or firmware. I've seen exactly that latter possibility reported by some people in user comments left at regarding some RAID devices.

Regarding your question about SSDs, I certainly would not assume that they are failure-proof. Again, just take a look at user comments left at Newegg for various SSDs if you have any doubts about that (although I recognize that those having negative experiences generally tend to be disproportionately represented in such comments).

Regarding reliance on CD media as a means of data backup, a good backup strategy should protect against loss of time as well as loss of data. As others have noted, you don't want to risk eventually having to re-rip a large CD collection.

Large capacity mechanical (non-SSD) external and internal hard drives are cheap these days. Just get one or preferably two for backup purposes (one of them to be kept at a separate location), and periodically copy any newly added files to them.

Bob, I use three standard 1TB Firewire drives - one in use and two backups. I store files in ALAC. The other mode of RAID, you mentioned - stripping used to increase speed (alternating data) doubles the risk. Wen one drive fails both are gone. Mirroring is better but in addition to virus susceptibility both can be damaged by controller failure. I use Firewire drives only because it frees main processor allowing me to use computer for other tasks (plus Firewire is native to Mac). It doesn't affect the sound in my wireless setup.
There are several RAID modes, some of which include stripping, data redundancy and parity redundancy which has speed as well as security. Of course, that reduces space efficiency so that each of my 12Tb NAS drives give me only 8Tb of effective storage.
Thanks to all for posting. I appreciate the comments. Just for the sake of disclosure, I have advanced degrees in computer science (emphasis in programming languages, compilers and computer architecture) and have worked as a software developer for 20+ years. I have a pretty complete understanding of RAID and backup strategies. I was just curious what some folks were doing.

Thanks again,
Sorry for preaching to the choir, Bob. One never knows the level of awareness re. everything associated with PC Audio.

Al: Interesting that you should mention surges. We're still trying to recover from one last month that Mother Nature dealt. Lightning hit a large tree near the house. Some A/C related issues arose, but mainly affected: were items with integrated circuits, USB and HDMI ports. No RAID in house, but ethernet switches and the PC's network adaper were toasted. -Mike
MRBM suggestion of the computer audiophile article is a good one, though info is seriously out of date and old. is anyone aware of similar but updated info, list?
I use Synology DS213j NAS with 2 red label Westgate WB 4TB hard discs running in parallel. The router is Netgear AC1900. Software is miniserver, so far so good for me.
