[Brokkoli]

Budget (including currency): 200 USD

Country: Norway

Games, programs or workloads that it will be used for: Work for school, Editing, A redular Daily Driver PC

Other details: 

Undecided wether the jump in cost between WD Black SN750 to WD Black SN850 is worth it for my usecase? Both are 1TB sized, SN750 is priced at 99USD here, while the SN850 is priced at a staggering 180USD. And while I know that this is a massive increase in price, I'm intending to use it until I'm expanding, and adding another unit of storage. Personally leaning towards 750, though from what I've read my usecase would benefit from the increased speed of the 850 ..

What is your use case? Also, do you have a CPU and mobo that actually support PCIe 4.0? That may seen like a stupid question, but a surprising number of people don't consider that before purchasing a Gen4 drive.

My CPU is probably (95% sure) the Ryzen 5 5600x, and I have the MSI MPG B550 Gaming Edge Wifi ATX AM4 Motherboard. I'm pretty sure the rig can support PCIe 4.0, but I'm not entirely sure..?
It'll just be used as a storage device, obviously. But I'm intending on using the machine for some light video and audio editing. Aswell as daily driving and some school work. Nothing heavy, but plenty of storage would be needed ..

With that CPU and board, you'll have one PCIe 4.0 M.2 slot available. The rest, if there are more, will be only PCIe 3.0. As long as you only have the one drive and ensure you have it in the correct slot with support, yes, you can get Gen4 speeds.

 

However, based on the use you're talking about, you don't need that. The only real benefit would be for the video editing, but you'd need to be working with like 4K/8K raw for it to make a difference.

Chris has it right, and said more politely than I would.  That price increase for the SN850 over the SN750 is stupid as balls.
