Storage Spaces fast enough?

[eobiont]

I moved to windows 8 and have created a 3x3TB storage space. I also have a 2TB drive and a SSD OS only disk.

My plan was to have SageTV write to the 2TB disk and then use SJQ to archive and comskip the files over to the storage space drive. I had read some people thinking that storage spaces in parity was not fast enough to use as the target for the sagetv recording directory.

So I got everything set up tonight and when doing internal copies from the 2TB -> storage space, I am getting sustained writes of 35MB/s. Do you think that is fast enough to use as a target for my recordings? It would be a whole lot easier to write directly to the storage space than to write to the 2TB drive as a holding pool and then copy over to the 3TB once the recordings are complete.

What do you think?

35MB/sec is plenty fast enough. That's about 7 times faster than a BluRay, and could theoretically handle 20 HD-PVR streams... of course, that's theoretical, and would instead be much slower when writing different streams due to seeking, but it should be fine for up to 5 tuners plus some playback.

I used to run software RAID-5 many years ago on winXP, and it handled 5 tuners fine back then with much slower drives.

Thanks. It will be so much easier to write there directly. I hope that it is somewhat reliable.

I have been reading some horror stories on the internet about Storage Spaces. But I figure there's probably > 1million users so some problems are bound to happen in that sample size. I just hope that it is more reliable than just single drives.

I have been using Storage Spaces on a Windows Server 2012 setup for about 6 months without any incidents. I spent a fair bit of time initially swapping out drives and causing errors and rebuilding my sever OS from scratch to ensure I could recover and never lost any data in my testing nor since I completed the setup.... I have 26.6 TB of which 16 TB are currently free. I use a parity virtual disk for all my media and mirror virtual disks for other data and important backups. Performance for reading or writing has not been even a consideration.

So far so good... I am a fan. It was easy to setup and basically just takes no maintenance.
