Is the compatibility list complete?

I’m wondering if a 10TB hard drive, either WD or one of the cheaper Seagates, would work if I swapped it in.

Thanks!

If you are asking about EX2 Ultra, you can refer to the HDD compatibility list here:

2 x 10TB drives work fine in the original EX2. I’ve been using them for the last year.
