Why use a switch and not use USB C straight to the computer? Also for SSDs the sweet spot for price is 500Gb at the moment, are you going to be running raid? Are you editing on a laptop?
Before anyone reads on - it looks daunting to me and I wrote it!
So have a look at this which is a great and more fun summary.
Apologies didn't see this message come through sir. Massively off topic now, but bear with me whilst I explain...
USB C is not what I need here, I need to cover off some other requirements, which will help explain my rationale. If I go the USB C route I will be limited to single drives and if I use large density cheap-ish spinning platters then I'll simply not get the speed out of them to perform editing. I would also have to be within arms reach of the drives - which will mess with my Zen like office (not really) but I don't want devices all over the place. If I use SSD's for the speed then it will cost a small fortune to get the amount of data storage I need. I've also invested in NAS since 2011 so it would seem silly to lose all the resiliency and have to use stand alone drives, bit of a retrograde step. The 250Gb's were a trial and were based on Sata so I didn't want to go all out, I've now switched to 2 x 500Gb NVME which is much better (speeds of between 1800-2700MB/s vs around 550MB/s on Sata), and as you say definitely the sweet spot at 500Gb
With 10GbE, or 5GbE as I'm sitting on now (more on that below), then I can have the storage up to 100m away from the computer as I'm running Cat7 cabling, and the data is accessible from anywhere I want it to be, or any device for that matter, even simultaneously.
I will be trying out multiple raid setups to get this running the best for me. Raid 1 over Raid 0 for speed and basic resilience, then Raid 5, 6 and 10 etc. All with and without caching and over 5GbE and 10GbE.
Even on basic Raid 5 with no NVME acceleration (and now over 5GbE - as I have moved onto a larger NAS with a better blend of capabilities but lower interface speed) I'm getting the speeds below - which is just about enough to get me to 4K editing. The 5GbE interface will tap out at roughly 500MB/s which is more than ample for editing anything in the 4k range that I can produce.
I also have the option on the switch to run LAPC port aggregation which I have tried on my old NAS with 4 x 1GbE and that worked ok, but it was time for a performance upgrade so I hit the reset button and went for some new kit.
To give an idea of the file sizes I'm looking at. I have imported the video that I took originally for the tow bar work (I'll do the work over again to get the detail right - I'm just learning - but the data size is useful if nothing else). Once imported and made into proxy media we are looking at the thick end of 500Gb of data. I can remove the proxy media when I archive it but that's a significant amount for 1 video and not all of that was at 4k either. I have been known to over-egg the pudding so to speak but I prefer to buy the right things and use them for a long time than to cut corners at the start and either not achieve my goals or be delayed re-visiting things every 5 minutes. Wether I decide to do lots of video's here (I started last year on basic door removal etc but not yet published) or just go for home video editing then
Here is a link to the new NAS I'm running from QNAP. So far a great device -
