Dual NAND on all M4 Pro options?

[Xephian]

Do all M4 Pro SSD options beginning with the 512 have dual NAND chips?
From what I’ve read all base M4s are equipped with dual NAND but haven’t heard much from M4 Pro SSDs. I’m assuming they do.

From the speed tests in this thread I believe the M4 Pro uses at least 2 NANDs

EDIT: Below post shows at least 4x NANDs

Copied from @Chancha's post later in above the linked thread:
On M4 mini:
256GB = 2 x 128GB
512GB = 2 x 256GB
1TB = 2 x 512GB
2TB = 2 x 1TB

On M4 Pro mini:
512GB = 4 x 128GB
1TB = 4 x 256GB
2TB = 4 x 512GB
4TB = 8 x 512GB
8TB = 8 x 1TB

EDIT: Still awaiting confirmation of the 4/8TB configurations. Maybe 2TB NANDS?
