Got a deadline for a huge 4K edit next week and need a Gen5 drive for my Z790 build today.
I read the T700 is fast but some reviews say it overheats even with the board heatsink. Is the FireCuda 540 better or should I just stick with Gen4? Which 5.0 drive actually works best?
> honestly if youre on a tight deadline for 4K stuff, the heat on Gen5 is a real factor. most of those new drives get incredibly toasty Saw this earlier and I actually have to politely disagree about sticking to Gen4! If your budget allows for the upgrade, the speed gain for 4K scrubbing is amazing. I love the TeamGroup T-Force Cardea Z540 2TB PCIe 5.0 NVMe SSD as a solid alternative. It handles sustained loads much better than the first wave of Gen5 units. Another fantastic option is the Corsair MP700 PRO 2TB PCIe Gen5 x4 NVMe SSD. If you get the version with the active air cooler, the thermal management is incredible.
I have been using the Crucial T700 2TB PCIe Gen5 NVMe SSD on my Z790 build for several months and I am quite satisfied with how it handles heavy video workloads. When you are dealing with 4K deadlines, those 12,000MB/s read speeds actually save a noticeable amount of time during asset ingest. Many people worry about the overheating, but in my experience, as long as you use the dedicated thermal guard that comes with high-end Z790 boards, it works well. You dont necessarily need the version with the pre-installed tall heatsink if your motherboard has a thick integrated one. The Seagate FireCuda 540 2TB Gen5 SSD is another excellent choice that I have tested. It uses the same underlying Phison controller technology, so performance is very similar across the board. I found that the FireCuda stays slightly more consistent during long 100GB+ writes, which is basically what you need for editing. Honestly, moving back to a Gen4 drive like the WD Black SN850X 2TB NVMe SSD feels slow once you get used to Gen5. Just make sure your BIOS is updated to the latest version for the best PCIe 5.0 stability. No complaints here, it has been a very reliable upgrade for my workstation and handles the heat just fine under the stock mobo plate.
honestly if youre on a tight deadline for 4K stuff, the heat on Gen5 is a real factor. most of those new drives get incredibly toasty, sometimes hitting 80C+ under heavy load which causes massive throttling. if that happens mid-export, your speeds will drop way below what a stable Gen4 could do anyway. basically, a top-tier Gen4 drive is often more reliable for sustained work because they run way cooler and dont require those massive tower heatsinks that might interfere with your GPU. one thing to check on your Z790 board is if using the Gen5 slot actually cuts your GPU lanes down to x8. most boards do that because of how the lanes are split between the CPU and the slots. its a trade-off many people dont realize until they plug everything in and see their graphics performance dip slightly. probably wont matter for 4K video but it can be annoying. before you pull the trigger tho, are you planning on using the motherboards built-in heatsink or are you okay with a drive that comes with its own active fan? also, is your priority the absolute highest sequential speeds for moving huge files, or are you more focused on high IOPS for smoother timeline scrubbing?
