What supplier would you recommend? WD and Sandisk have been my go-to for all things storage, but I prefer to pay a premium up to 20% for better quality.
Seagate, Samsung.
I'd go with WD over Seagate every time (for spinning).
There is no way you are in good faith recommending Seagate....
My experience with WD spinning disks has been great. I've had two Sandisk SD cards fail which was a bummer but they both went into a read-only mode so I didn't lose any photos. I've switched to Samsung's high-endurance line for those.
