I plan on upgrading my OS drive (M.2 PCIE 4.0 256GB) to an M.2 PCIE 4.0 4TB drive.

I was initially planning on purchasing a Samsung 980 Pro 2TB drive, but after the firmware fiasco (and how they dealt with customers), I decided to try a different vendor.

I've narrowed down my choice for an OS drive between the WD SN850X 4TB and the Seagate FireCuda 530 4TB.

I was wondering what the forum recommends, as I'm a little worried with the reliability of the FireCuda (as well as Seagate drives in general).

The Firecuda seems to have quite a few bad reviews regarding drive failures on Amazon (at least compared to the WD drive):

However, from what I've read about the WD drive, it seems to thermal throttle quite a bit compared to the Firecuda (which also leads to drive failures).

Given that this drive will be used in a Dell laptop (5330 2-in-1), I'm not sure if the WD drive will be able handle the limited airflow of the laptop.

I've looked at other drives as well, but they seem to have worse reliability than the WD or Seagate, and given that this will be the primary/OS drive, I'm worried on taking a chance with a less reliable drive.

Regardless of which drive I purchase, I plan on adding a thin heatsink like the following:,Heat-Copper/dp/B07YC1HTFR/ref=sr_1_3?crid=29MUIB4XRGOCF&keywords=m.2+heatsink+laptop&qid=1671861030&sprefix=m.2+heatsink+laWD SN850X 4TB vs Seagate FireCuda 530 4TBptop%2Caps%2C346&sr=8-3 well as using the following thermal pads:


Any recommendations (regarding drives, heatsinks, thermal pads, etc.) would be greatly appreciated.

Thank you,
Either one will be fine.

I have a 980 PRO and a SN850X both great drives.

the Sn850x is on sale for 229, so I would buy that one based on price alone. (prime sale)
