Does CaptureOne (Win PC) now work efficiently with a NAS?

Hi there 

I have seen a lot of posts about poor performance when using a NAS. I hope to purchase a NAS in the coming months so would like to find out if it's going to be fit for purpose, before spending the £2k needed for a properly specified NAS + 10Gb network upgrade. 

My current system is: Win 10 Pro. Dell XPS 15 laptop, Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz, 16Gb RAM. All CO catalogues and RAW files are stored on external SSD's. I have ageing (and slow) HD's for backup. [NB: Editing off the RAW's on the backup drives is not an option as the HD's take about 20 seconds to spin up to operating speed, and they spin down after seconds if not activley being used. So this causes serious and unbearable delays when editing]. Also if it's useful I use a Sony A7III so my RAW files are typically 50Mb.

I would use the NAS as the storage medium for all my RAW files. I only need to access them from a single computer, currently the Dell XPS laptop, and I intend to keep the catalogue files on external SSD's, so database management is as fast as possible. I intend to use a 10G network, and to instal fast NVMe SSD cache on the NAS to boost processing and transfer performance. I want to edit directly off the NAS rather than to keep local copies of RAW files on SSD's, as the workflow needed to copy RAW files from NAS to local SSD's when editing - and then back again - is to be honest a total pain, especially since relocating / reconnecting referenced files in CaptureOne is not exactly fast at the best of times. (Yes - I continually experience the long delays caused by re-indexing the catalogue once files have been moved that everyone using Win PC seems to be reporting).

I believe my intended system 'should' perform amazingly well (after all it is going to be fast enough to edit multiple 4k video streams directly off the NAS - so it should be able to cope with editing RAW photo files! I've done a lot of reserach on NAS systems and networking (I recommend 'NAS Compares' YouTube channel, for anyone ineterested), and I have a lot of experiece working with CaptureOne catalogues (at least on local systems). But I am VERY concerned by the comments I read that:

a) general performance is commonly 'very slow' with Capture One when using a NAS, so there is no advantage to using a NAS in terms of editing efficiency

b) it is not recommended to keep your catalogue files on the NAS (even if you place them on a NMVe system drive for super fast access?), so there is no advantage to using a NAS in terms of centralising ALL assets (database files and media) thereby enabling access from ANY networked computer running CaptureOne. 

c) every time Capture One connects to a NAS it has to re-index the catalogue, so there is no advantage to using a NAS in terms of speed of access

In summary - everything I understand about networking technology and NAS systems tells me that it's a no brainer, and that so long as it's specified correctly will provide a number of great advantages and efficiencies. BUT everything I understand about CaptureOne tells me it just might not work as inteneded. 

I'm hoping someone can tell me I'm wrong - and that using a NAS today with CO is not a problem at all! Or that someone has experience with using a NAS and can recommend a workflow/setup that is proven to be fast and efficient for editing. Or that someone from CaptureOne development can provide detailed information regarding what does work now, and what is definitely coming in a planned future upgrade.

Sorry, long post I know. But I think there a lot of users like me with similar interests that would like to know the answers.

Thanks and Best Regards
