What HDD for thunderbolt 3 NAS / Storage ?

[Enquiries]

I am looking at Thunderbolt 3 NAS or external drives - what storage would you suggest for high(ish) speed single user but good value performance - at what point am I better off getting a thunderbolt storage (with SsD?) vs thunderbolt 3 NAS - I am confused as most of the consumer HDD seem to be 7200 so don't see how this can be fast

Once you create a RAID on 4 drives, this volume becomes faster than an SSD. Different RAIDs will perform at different speeds, but most of the time it will be faster. But if you are a single user, then the DAS option will probably turn out to be cheaper. NAS is a good choice for collaborations and sharing files across networks and the internet.I hope this helps.
