So I am finally upgrading to an AM5 setup with a Ryzen 9 7950X and an X670E board but man the SSD choices are stressing me out right now. Ive been building rigs since the DDR2 days but this whole PCIe 5.0 heat situation is new territory for me and I dont want to buy something that just throttles after two minutes of heavy use. I do a lot of 8K raw video scrubbing and local LLM work so I need the absolute fastest sustained write speeds possible but I'm seeing conflicting reviews on the Crucial T705 vs the T700 or even just sticking with a reliable Gen4 drive like the SN850X.
Here is what I am looking for:
- Budget: around 350 bucks maybe a bit more if its actually worth the jump
- Location: I am in Southern California and it gets hot in my room so thermals are a massive deal
- Capacity: 2TB minimum
- Timeline: Need to order by Friday to finish the build over the weekend
I am worried if I go Gen5 the tiny fans on those heatsinks are gonna whine and drive me crazy but if I stay Gen4 am I just leaving performance on the table for this kind of CPU? I've never seen speeds this high and honestly it is kinda giving me anxiety thinking about the drive dying from heat or something. What are you guys actually seeing in real world tests for the Ryzen 9 stuff specifically...

In my experience, the heat anxiety with Gen5 is real, but some brands handle it better. If you want the speed but hate the idea of a tiny whiny fan, the MSI Spatium M570 Pro 2TB PCIe Gen5 NVMe is the one. It uses a massive passive heatsink that actually works for long LLM sessions without throttling. It's built like a tank and definitely feels like a premium choice for an X670E setup. If you want to play it safe because of that SoCal weather tho, just get the Samsung 990 Pro 2TB PCIe Gen4 NVMe. I’ve used these in high-end video rigs for a while and they’re incredibly reliable for sustained writes. You wont get those crazy 14GB/s benchmarks, but it stays way cooler and is basically bulletproof. Tbh, for 8K scrubbing, the 990 Pro is still a beast and you wont even notice the difference unless you're staring at a progress bar with a stopwatch. Plus, it saves you some cash for other parts of the build.

@Reply #3 - good point! Honestly tho, I disagree about jumping to Gen5 right now. In that SoCal heat, Gen5 is a reliability killer! I love the WD_BLACK SN850X 2TB NVMe SSD for this build. It has amazing sustained write consistency and wont bake your other components. You save over $150 and the random 4K performance is fantastic for LLM work. Gen4 is way safer for your wallet and your data!

TL;DR: Get the Crucial T705 2TB PCIe Gen5. In my experience, its unbeatable for 8K video. Use your motherboards chunky passive heatsink instead of a tiny fan to avoid that annoying whine.

Ive seen plenty of drives come and go, but Gen5 is a different beast. For heavy LLM work and 8K scrubbing, the Sabrent Rocket 5 PCIe Gen5 2TB NVMe is my go-to because it handles sustained writes better than most in my experience.
- Sabrent Rocket 5 PCIe Gen5 2TB NVMe
- Samsung 990 Pro 2TB PCIe Gen4 NVMe The Sabrent stays fast without needing those annoying tiny fans if your motherboard heatsink is solid.
