Thunderbolt 3 DAS vs NAS for C1
I'm looking to invest in either a NAS or DAS for long term storage and editing of my master catalogue used from my 2016 MBP with Thunderbolt 3 ports. I've read, but can't find the reference, that C1 doesn't work too well with network volumes, so would I be better off with DAS?
If DAS, I was thinking of one of these Terra Master bays, and for NAS, I was thinking of a Synology DS220J. Any other recommendations or advice?
Cheers

The issue is, read write speeds and access time over Gigabit cable. DAS is much much faster in both compare to NAS. v20.1 supposedly better with NAS now however that doesn’t solve the problem of bandwidth. CO requires to access previews and sometimes original RAW files to compute stuff. So the suggestion is to have catalog and previews in the internal SSD and the rest in an external drive.

Cheers, I was always going to have the catalogue and previews on the internal drive, I'm just working out the best place to store the RAWs and final edits. It sounds like DAS would be most suitable, especially, as I only need to access them from this one laptop.

Without doubt. TB3 has a bandwidth of 40Gbps, Gigabit Ethernet cable has 1Gbps. If you can, get NAS as well to have a double copy of your RAW files. I do that way.

Hi
I've been using a NAS for several years now. It's basically an old PC running NAS software with 24 spinning-rust HDDs. I can saturate the 10GB ethernet reading and writing from my old 2009 MacPro.
I store the catalogues and previews on a fast internal drive. I do have some infrequently used catalogues on the NAS and it's perfectly usable - the open times are longer though.
If your raw files are 100MB each, it will take about a second to read it over 1 GB ethernet. However the benefit of a NAS is that if you ever decide to move to the dark side (from MacOS to windows) the NAS will just work. You could always use a thundebolt -> 10GBE adapter and connect to a suitable NAS (just to muddy the water).
I know that I will not be getting the cheese grater MacPro. So the NAS will make my move to Windows easier.

Sure but there is cost of adaptor, 10Gb switch, 10Gb NAS, 24 HDD and that's still a 1/4 of the TB3 speed. Also for sequential reading you can have an access in a second for 100MB file however access time etc delays that much more than a second.
On the other hand if you already have all that 10Gb system with 24HDD, the sure you don't need to get a DAS :)

Hi
Actually I did not see an indication about how much of RAW data you are talking about accessing here on an external storage.
Yes, I would also go for a DAS as the connection with Thunderbolt leaves more bandwidth. But you mention a TerraMaster two bay DAS but don't mention how you are going stack it. Are you going to use two SSDs or do you want to go for two conventional harddrives? And secondly how will you configure your DAS in terms of RAID used? Will you make a stripe set with RAID 0 or will you go for RAID 1 Mirroring?
Why do I ask this? You will have to be aware that one thing is the speed of your connection but another limitation (and even more important) will be the speed of your disks/SSD inside the DAS and what RAID configuration you choose. Assuming you use two conventional HDs in RAID 0 you won't probably get faster speeds than 480MB/s (2x the physical max speed of one HD) to be transferred over your cable, while using two SSDs will give you a much faster transfer speed over Thunderbolt but finally the maximum Speed you could get would be dependent on the DAS limitation (for the 2bay TerraMaster they say 760MB/s)
So eventually one single direct attached SSD drive (like a Samsung T5 SSD with 2 TB) would be already sufficient and would do the trick and could be a better solution and even be very portable. But that really depends on the amount of RAW data you estimate to collect over time.
Until recently I by myself used a 4bay DAS on Thunderbolt 2 and was happy using it with Capture One and around 3TB of RAW images. That works well when having the C1 library on the internal computers drive. Today I am lucky having an 8TB internal SSD and using the 'old' DAS as a backup.
And that's the last I want you to remind: don't forget a BACKUP !!! No DAS, NAS or SSD or HD is infallible and all of them can get brocken.
Cheers, Andy

Cheers Andy for that thoughtful post. In the past week I've committed to a solution (the Terra Master TD2 + 2 4TB WD Reds, so fingers crossed it will work how I hope. So, currently my combined raw + output tiff catalogue is about 1TB, but as I continue through my backlog, I think it will grow to around 2TB. My intended workflow is to use my internal SSD to host sessions for editing images. Thus only processed raw files, and completed images will be stored on the DAS with the catalogue and previews again on my internal SSD. Thus I don't think thoughtput will be massively important, but redundancy critical. This spinning rust will be in RAID configuration, but I do need to figure some offsite / cloud backup....

Glad to hear you have a solution!
I can recommend backblaze for offsite backup - I have nothing to do with them - but I've been a very satisfied customer for several years. I have over 4TB backed up on their servers.

Cheers for the recommendation, it’s always been backblaze vs crashplan as the usual suspects, glad to have a vote to point me in the right direction.
