Adding to Hector and Neil’s excellent observations above, I do run FCPX on a Mac Mini M1.
It is not my primary “work-station”, but it serves my FCPX customers very well.
On the Mac I have a mix of Samsung T7 drives hanging off a OWC Thunderbolt Hub.
For HD and 2K absolutely fine, for 4K you’ll start pushing it a bit.
Being old fashioned, I like to keep my project (Library) on the main drive (the one with the OS), and source footage on an external drive – depending on size of the project.
The T7 drives are “only” 1,050 Mbps.
However, I just recently got a Samsung T9 which will go up tp 2,000 Mbps.
So far the T9 (on a PC) is performing as well as the T7.
If it is not for editing, Samsung has just released an external 8TB SSD – T5 EVO Portable SSD USB 3.2 Gen 1
WARNING – small print for the T5 EVO:
“Up to 3.8x faster than an external HDD with read & write speeds of up to 460MB/s”
Which is interestingly bad on Samsung, as their EVO Pro PCIe 4.0 NVMe M.2 SSD cards (no enclosure) will run “up to 7,450 / 6,900 MB/s sequential read/write speed”…
Full disclosure, I have just purchased 2 x EVO Pro’s to expand my new PC Laptop from 1TB to 9TB of internal storage (with space for another 4TB).
Yes, although the drives can go faster, because of the USB connection, the Samsung T-models might not reach 7,000 Mbps.
What is nice about most of the SSD external drive brands are that they are reaching the cost point of what video tapes would have cost back in the day. At which point you might be better off keeping the Crucial X9 SSD for sitting on the shelve as a “near-online” back-up, and use something faster for editing.
Just a point of view.
