Any figures for how some of these NAS boxes perform whilst a disk is being rebuilt? Especially the RAID-5/6 capable ones? How long do the rebuilds take and does streaming suffer whilst they are in progress?

I'm trying to revisit this Sticky as the original post is over 2 years old now.But thankfully in the main part, the information is still valid.
If you have any suggestions for updated content or changes, then please let me know. data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
yeah, I have a readynas in RAID5...well actually its their proprietary XRAID5 - its proper redundancy - I can have a media stream running, 5 people accessing it, downloading stuff etc, and pull out a drive and there is no effect whatsoever, put a new drive back in, it rebuilds in the background ...seamlessly, in a couple of hours ...just how it should be data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
Tidied a few bits up and added a "FileSystem" section.
Thanks. It's a very helpful guide to clarify concepts. It's a must read before doing anything.
I don't consider a Qnap 509 to be high-end, it is a sub 1000 ukp devices, has excellent software and pushes 85MB/s over single of its dual GigE ports.
In my eyes, a unit at over £600 with no drives is classed as "higher end".
From the queries in the forum, most people on here want consumer based units around the £150-£300 mark to stream a few movies, which I pitched this FAQ at.
I can't imagine the majority of Joe Public want to spend £850-£900 on a 5 bay unit with 5 drives to stream an iTunes collection.
Maybe we just have a differing of opinion regarding what constitutes "high-end"?
Granted, technology moves on apace as I've had to change this FAQ on numerous occasions since the original post in 2007.But I think the latest revisions are quite relevant to todays models.
It might be worth pointing out that a NAS with a RAID system still needs to have a backup done. Don't just rely on RAID for your backup as you could end up losing stuff.
Completely agree John, don't why I'd not added that earlier. data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
Done!
Bit of a typo there mate.
Great guide BTW, helped when I was choosing my NAS.
