NVME Capacity limitation on laptops?

[Moonzy]

So i was browsing for 2tb NVME SSD and one of the shopkeeper told me that some laptops (if not most) are limited to 1TB sticks, 2TB might not work

i did some googling and it seemed to be the case.

 

why? and does desktop have such weird limitations?

Many laptops are limited to single sided nvme drives, so that could be the case.

Can also be firmware limited based on the model. For example: a little 14in quad core Pavilion thin and light with only integrated graphics, it would be exceptionally unlikely that you would need beyond 2TB of storage total. vs something like a Dell Precision mobile workstation laptop, which is likely to have the possibility of carrying huge files for things like renders and simulations, it would make sense that it would need 2TB+ of storage.

This sounds like a load hooey. It would make no sense why the manufacturer of the laptop would make the bios limit space for a drive

I can only guess they only validated so far, so wont state outright that higher capacities could be ok too.

what technical limitation would this be? it's not like RAM where there's quad rank sticks or something

shop says the laptop might refuse to work, they also searched up my laptop's model and found some forum mentioning the same as well, though i can not find that page now

Physical space. There isn't enough room for the m.2 drive to have chips on both sides.

i see, so there's no reason the laptop would refuse to work if the drive physically fits?

Any drive should work. I haven't seen any laptops lock down the models of ssd you can use.

 

The 1tb max is probably just the max size that it was tested with at launch, and those supported lists seem to never get updated.

aight, thanks!

Space limitation. It is possible that a thin and light would have a clearance limitation for a dual sided SSD. generally large capacity NVMe drives have NAND packages on both sides.
