Gen5 nvme over gen4

Gen5 run hot, Gen4 not as much. With decent case airflow and no obstructions you should be ok, worst case scenario you can always buy an NVME heatsink searately and stick it on your drive if you're finding it gets hot.
Not sure if mine is gen 4 or 5 but its pci 4.0 so I'm guessing 4 and... it gets hot. Really hot. Not sure if its the capacity (4tb) but my other 2tb drives run cooler. Swapped it around in several sockets before I found one thats reasonable but its still 69c at idle and it creeps up over time (other slot hit over 100c, ouch) and thats with the mobo heatsink screwed down (yes I removed the protective plastic)

I think Samsung quote up to 80c operating temp before it's classed as 'out of spec' but even so... 70c for an idle drive is well hot.
It shouldn't be idling more than about 40 or 50 tops, and most of that will be residual heat from cpu/gpu if its in close proximity.. So you'll never realistically see an idle temp of under 30c or so, for example

Well I got a partial answer to that it turns out there are two main chips on the pcb a large square one that seems to be the nand memory and a much smaller one thats probably the asic, the smaller chip is not as high than the larger one i.e. when you have a single thermal pad to cover the lot as mine and I'm guessing most motherboards do the small chip is not getting covered by the pad at all i.e. its hanging high and dry with a gap between it and the pad. I had to cut a small portion of thin and squishy thermal pad to stick over the chip to meet the main pad on top. This dramatically reduced the temperatures to about 50-60c. The other two sensors are a much more reasonable 43c or thereabouts. Running a crystaldiskmark benchmark raised the temperature to about 75c which is under the operating temperature of 0-85c for this drive as opposed to well over 100c before (yikes) so I guess that'll have to do for now.

Its not actually the first time I've encountered pad clearance issues I had an aftermarket cooler for the gpu once that failed make contact with some VRM chips that resulted in them running stupid hot had to double up on pads with that too the moral of this tale is check your temps with HWInfo having had hot drives before its the first thing I checked. These drives were on sale for a while which is why I got it cheap I wonder if the reason is they've had a high failure rate from overheating chips from people who weren't aware

PCI-e 5.0 is a marketing gimmick for consumer PCs and adds literally nothing whilst costing way more and running hot.

If you are a database manager with a huge locally hosted set of database files then sure, PCI-e 5.0 makes absolute sense but otherwise, it won’t make any difference and most database systems are hosted on a dedicated server anyway.

PCI-e 5.0 is more useful for servers since it’s used to connect pci-e devices to the server using fewer pci-e lanes (you can get the same performance using half the pci-e lanes since the bandwidth is doubled).

For PC gaming and consumer applications, pci-e 4.0 is great and a drive like the 2tb SN850X is hard to beat for the money.

Doubt you'll notice the difference in games with gen 3 either
 
I have a gen 3 WD Blue and gen 4 Kingston, don't notice differnce in games, only in crystalmark tests. Also have a 500GB 2.5" SSD used for Windows boot that is plenty fast enough.
Yeah I 100% agree.

I’ve also got many SSDs including two SN850X 2tb and some cheap small PCI-e drives and an old 1tb SATA Samsung 850 evo and I’ve never been able to tell the difference.

I’d still prefer an SSD with a DRAM cache so if the SSD fills up it doesn’t slow down but that still not a huge issue.
 
Currently thinking of another NVMe to try a dual boot dual NVMe system, I use a 1tb 990 Pro for the OS and desktop work, but for some reason I am now wondering if I should run a 4tb Gen 5 NVMe as an OS all round drive, and if it could even rip UHD and such a bit faster in bulk before letting then transfer overnight to HDD storage. In doing so the 1tb drive simply gets repurposed for the Linux trials.

My head is saying don't bother, but another part is looking for an excuse to try out and justify a Gen 5 drive. Yet I know in reality the speed of moving such files isn't so much the NVMe drive speed, but the system bottlenecks, especially initially with the X4/x6/x8 speed of a UHD optical drive and it's wired data transfer speed.

Not sure how much time it would save if I got back into encoding and transcoding DVD, Bluray and UHD. Or even if the 7600x would be a bottleneck at that point. Not a lot of figures on it from what I have Googled so far.
 
I'd just go for a 4TB 990 Pro.
Yeah, I agree, that or SN850X.

You are overthinking this. It’s not going to make any difference going for a gen 4 drive.
