LISTEN TO ME
I AM A SEAGULL
OF WEALTH AND TASTE


I have a 960 EVO that I installed in an M2 slot that's right in between the top PCI-e slot and the CPU socket, and then installed the dinky little "heatsink" that came with the motherboard (it's more like a solid block of aluminium with a thermal pad on the bottom) on top of it. Since it's crammed in between the back plate of the graphics card and the CPU cooler, it naturally gets pretty toasty and it sits around 50-60 degrees C most of the time. Now, I have some vague recollection that NAND storage actually wants to be pretty warm, but I just figured I'd check if anyone knows if there are any articles about longer term effects of this stuff. There is a second slot on the board way down at the bottom that I could move it to, but I think the airflow there might not necessarily be better - it's just not quite as close to a bunch of hot things.

Relatedly, anyone know the difference between the two temp sensors on the 960 EVO? Wild rear end guess says controller vs NAND but which is which?

I found out that my benchmark results with my 960Evo are down, but not by 50% - flashing the card BIOS improved it.

It's around 15% down at 4k reads since pre patch though. But this is a terrible benchmark since I have now:
- installed the Samsung driver
- updated the SSD bios
- patched windows

Not a good chemist

Is it weird that the 4k random writes are faster than the corresponding reads?

no

mostly to do with how SSDs (and nand flash) work really

Looking forward to the NVME MX500 numbers, hope there isn't a big premium over an equivalently-sized SATA version.

Is there any practical difference between 2D and 3D NAND for M2 SSDs other than $50?

WD Blue 1TB PC SSD - SATA 6 Gb/s M.2 2280 Solid State Drive - WDS100T1G1B0B [Old Version] https://www.amazon.com/dp/B01LYOKOJ...a_pfjyAbXKRV369

WD Blue 3D NAND 1TB PC SSD - SATA III 6 Gb/s M.2 2280 Solid State Drive - WDS100T2B0B https://www.amazon.com/dp/B073SB2MX...a_fjjyAbMBR5HZW

I need extra space for my Steam library and mods. Windows is already on a 1TB NVME drive (that Toshiba one).

No, but the first link is quoting a used price.

Theoretically 3D NAND might have a larger process, therefore it could have better longevity.

Oh, good catch! Non-used are also $300, so I might as well go with 3D NAND when I pull the trigger.

Thank you!

An 840 EVO is going to have serious drops in overall performance as it gets filled up

the MX500 loses only like 7% in sequential when filled and micron's habit of overprovisioning 28% for consumer drives leaves IOPs relatively untouched

Oh that's good to know. Thanks.

My 1 TB 840 EVO's got 118GB free space left and I've been putting things on my HDD. May be time to do away with the spinner.
