[Bob Zelin] “Why on earth are you using RAID 0, with an ATTO R680 card ? The whole point is that if a drive fails, you don’t lose all your data. You MUST use RAID 5 for this system. “
Bob, I don’t mean to be adversarial: RAID5 is not a must on a 4-drive box, especially when there are multiple levels of backup:

[Alan Stephens] “I am running PrPro 6.0.0”
Update CS. Premiere Pro should be 6.03.

Thanks, great info.
Wonder if there is a way Premiere Pro (or AE) could let the user know it’s starving for memory, short of just slowing down.

[Pascal Greuter] “I think a NAS is to simple and not reliable enough for what we want to achieve.”
Can’t say I agree with that assessment but glad I could help:
– Maxx Digital Final Share 10G is a NAS
– GB Labs Space is a NAS
– complexity is the No. 1 enemy of reliability
– SAN (in its video-related sense, not General IT) – was and is a “hack” to bypass Ethernet and TCP/IP limitations, that are much less limiting these days vs. 5 years ago.For video related purposes, there is no question for me that the future is in NAS, for collaborative editing.
Bob Zelin’s support for Maxx Digital Final Share is the perfect indication of it. 🙂

I second Jon that the first step is to define the budget and requirements, although to even start thinking about a budget, it helps to know what the choices are.
NAS vs. SAN: NAS is more affordable, less rigid, less complicated – so let’s look at NAS.
Assuming video bitrates under 1Gbs (ProRes, H264, MPEG, etc. – no uncompressed HD), and four simultaneous editing sessions each working with one video stream, the aggregate bandwidth the NAS must sustain is roughly 4Gbs.
The ingredients for such a NAS are:
– a box holding the motherboard and 8+ drive bays
– 4+ 1GbE ports with link aggregation capability, possibly with an option to add 10GbE ports later on
– a decent switch that also supports link aggregation and possibly 10GbE add-on modules
– Linux Storage Server (or custom flavor of it)
– DrivesThe above BOM (bill of materials) is less than $2K diskless and around $4-5K for 24TB – both without Linux, purely for the hardware.
Synology and QNAP will charge around $3-4K for a diskless appliance and will not support anything related to editing. (Been there, tried that.) I also don’t know of any good VAR that uses Synology and QNAP or other general purpose NAS products for editing.
Then there are people like Maxx and GB Labs who sell and support NAS servers specifically for editing – and they charge for it.
GB Labs Space, for instance, costs over $20K for a 24TB box meeting above requirements. Not sure about Maxx – probably in the same ballpark. GB Labs Space NAS is an amazing piece of tech though, scalable to 10+ simultaneous editing sessions with high bandwidth video streams.
So the choices are, as of today, a roughly $5K NAS appliance that is not supported for editing, or a $20K+ NAS or SAN that is.
I am not sure if this helps – but figured I’d share my findings with you. 🙂
The ingredients are simple and relatively affordable, it’s the cooking that costs.

What version Premiere Pro (6.0? 6.03?), NVidia CUDA driver are you running?
-
No I haven’t, and despite doing systems integration for a living, wouldn’t even attempt to unless there’s no other choice. That said, it can be done – which isn’t the case with the GPU for sure, and very unlikely – with a CPU.

[peter tours] “Thats exactly what is happening . 15.96 gb out of 16gb yellow, active. I assume that means its also using my hard drive, which really slows things down.”
Yes, when memory gets full, the systems starts offloading chunks of memory to the hard drive, and that is a really slow process.
[peter tours] “I went ahead an ordered the ram since the investment was much less than a gpu..”
Good call.

650M is supported by Pr 6.02/03, so I’d just confirm you have “MPE GPU acceleration” in project settings, and if so, you’re all set.

Personally, I’d go with a faster CPU and GPU – simply because upgrading storage is much easier than CPUs and GPUs. You’d be able to replace your HDD with an SSD or a hybrid drive fairly easily in the future – not so with a CPU or a GPU.
