Upgrading the SSD (M.2 NVMe) on a Dell Inspiron

Hi everyone!

I'm looking to upgrade the M.2 NVMe drive in my laptop—it's a Dell Inspiron MacBook Air 15" model equipped with an Intel Core i7.
Right now, it has the stock 512GB drive, but I’m really hoping to swap it out for something in the 1TB or 2TB range.

According to the official Dell website:

Storage options include:

256GB M.2 NVMe™ PCIe® 3.0 SSD
1TB SATA 5400RPM 2.5" HDD, 256GB M.2 NVMe™ PCIe® 3.0 SSD
512GB M.2 NVMe™ PCIe® 3.0 SSD
1TB M.2 NVMe™ PCIe® 3.0 SSD
1TB SATA 5400RPM 2.5" HDD, 128GB M.2 NVMe™ PCIe® 3.0 SSD
1TB SATA 5400RPM 2.5" HDD, 512GB M.2 NVMe™ PCIe® 3.0 SSD

Based on those specs, it looks like they're implying 1TB is the absolute ceiling.

Is it actually that restricted? If I try to pop in a 2TB drive, is there a chance it just won't work or won't be recognized at all?

I think you’re talking about the specific drive options they ship with that model, rather than the absolute maximum capacity.
The real bottleneck usually comes down to which partition style you're running.
With the old MBR (Master Boot Record) system, you're stuck with a 2TB limit and a maximum of four partitions per drive.
The newer GPT (GUID Partition Table) doesn't really have those kinds of restrictions on size or partition count.
To pull off GPT, the laptop needs to be running UEFI BIOS; if it's set to Legacy, you're stuck with MBR.
That said, I'm fairly certain a 2TB drive should work fine, unless they went out of their way to bake some weird custom BIOS limitations into this specific model—but I highly doubt that's the case.

Thanks so much for the reply!

You don't need to swap out your current M.2 SSD if there's an open slot for a 2.5" drive—and looking at the specs, it seems there is. I'm guessing you aren't running a traditional hard drive in that laptop right now.

Based on what's listed here, the laptop supports 2.5" SATA drives. You could just pop in a standard SATA SSD, which won't break the bank, and then you'll have both drives working at once.

For example:

Yes, there’s actually an open slot for an extra SSD, though you’d need to pick up a mounting bracket and a cable first. Honestly, since the price difference between upgrading the M.2 and just adding a SATA drive is pretty negligible, I’m leaning toward whichever way is easiest. (Mind you, I do already have a 500GB SSD lying around that I could always just toss in there.)

Are you positive you actually need an adapter, a stand, and a cable? Did you test this out yourself, or did you just read about it somewhere?

Usually, you just plug a 2.5" drive straight into the fixed connectors and secure it with screws.

You could always try using the one you already have.

I definitely need this one: https://www.amazon.com/JUTOSHUR-2-5i.../dp/B096SYN6X3
I've done my homework online, and I also double-checked when I was installing that extra 8GB of RAM earlier. It's just an empty slot—there's no built-in cable or connector available on the motherboard itself.

I'm looking to upgrade the M.2 NVMe drive in my laptop. It's a Dell XPS 13, 15" model, running an Intel Core i7.
Right now, it has the factory 512GB drive, but I'd really love to swap it out for a 1TB or maybe even a 2TB unit.

According to the Dell website:

Storage

256GB M.2 NVMe™ PCIe® 3.0 SSD
1TB SATA 5400RPM 2.5" HDD, 256GB M.2 NVMe™ PCIe® 3.0 SSD
512GB M.2 NVMe™ PCIe® 3.0 SSD
1TB M.2 NVMe™ PCIe® 3.0 SSD
1TB SATA 5400RPM 2.5" HDD, 128GB M.2 NVMe™ PCIe® 3.0 SSD
1TB SATA 5400RPM 2.5" HDD, 512GB M.2 NVMe™ PCIe® 3.0 SSD

Based on their specs, it looks like the max capacity they support is 1TB...

Is it actually that limited? If I try to pop in a 2TB drive, will it just fail to work or won't the system recognize it at all?....

Micron lists guaranteed RAM and SSD upgrades for most laptops on their site—stuff that works 100%. They don't have anything listed for the Dell XPS 13IA, though they do list options for the Dell XPS 13EA. Not sure what the deal is with that one letter difference... But according to them, the Dell XPS 13EA handles the 4 TB CT4000P3PSSD8 without any issues at all.

I’m pretty sure it ought to be compatible too, but I got a little turned around because the Dell Inspiron support pages keep throwing around phrases like "up to" or "maximum specifications for the upgrade." It makes me wonder if they've actually placed some kind of artificial cap on things, especially since I know people are out there pushing these machines way past their intended limits these days.
