I have a existing wd duo 20tb in raid configuration back up / redundancy but it is real slow in disk speed test especially when migrating large files in mass i am currently updating my lightroom catalogue as i have a new pc ,which is painful meaning i have to import on to drive basically having two copies of each image until i delete the old the version remind me never loose lightroom catlogues or delete them all ,not really knowing the best way to save my images or how catalouge correctly some people have multiple catalogues ,i have purchased a das qnap tn-02 hoping this will improve things for faster read and writes over my existing wd duo ,i also purchased a iron wolf pro 16tb hoping to get a second one that iwas going to install on the qnap but i might change this as synology are getting bad press at moment with used sales of hard drives used on crypto farms etc although i think this is more exos range ,so what i am really asking is sata iii always going to be my bottle neck wth read write on das drives with mechanical drives even if transfer rates are greater now with thunderbolt and usb 4.0 etc .Is it worth getting a owc back up soloution or gtech or lacie if i am only buying mechanical drives is ssd3 always going to be the bottle the neck with read writes .Any info much appreciated

Thanks for trying to deciefer my bad english ,not sure what is the slow bottle neck it could even be the cable (usb 3.1) usb c ,for example when i test my WD Duo 20tb it is set for raid 1 probably the slowest option i know but the safest ,i get a write speed of 26.1 mbs and read speed of 130mbs ,which is painful for my updating of my lightroom as i use this as my main storage ,guess the quicker i get my qnap das up and running to see speed differences which will be interesting ,I do have my lightroom catalogues now on my main c drive which is the polar opposite of the wd duo it is a 1tb wd black sn850x nvme pcie ssd with 5000 read and writes ,which is probably to quick for my purposes and secondary samsung evo 4tb 970 ssd which is 500mbs read and write .
I get your point that mechanical is safer than ssd in the long run which makes sense ,so with the qnap das the mechanical drive will still be the slow point which looks like it will be 2x iron wolf pro seagates with 2 x16tb drives in a raid 1 array .
well i have finished copying everything into a new lightroom catalogue this was the issue as my wd duo is slow at writing filrs but the read is fairly reasonable ,or workable ,glad i am not importing large video files either that would slow it even more ,still i think my qnap will have a better therotical speed over the wd duo and maybe the iron pro wolfs have a slight better effiecency ,i think the wd duo disk are the red wd types ?

also made a crystal disk check on my wd duo i get 170+mbs in sequential read and writes check ,but once it starts using rnd4k it falls apart and drops below 2-3mbs ,even my 1tb wd black sn850x nvme pcie ssd drops from 6000 mbs read and write to 100/88 read and write 1000/ 350 in 4krnd so kind of take disk speeds with a varying degree of a pinch of salt depends on your file sizes also .
