Okay. Please help me as I ask COMPUTER BABBY QUESTIONS.

I have a Thinkpad T14 Gen 3 (AMD).
It has a 256 GB HD. That's too small. I want to buy a new, bigger one. I have a sense the good hard drives these days are "M.2".

Lenovo's specs page

lenovo.com/ca/en/p/laptops/thi

doesn't say anything about "M.2". It says the hd is "PCIe".

I run "lshw" to see what's on the computer. It says "NVMe".

How do I find out the bestest fastest aftermarket drive Canada Computers carries that my computer will support

I only understand computation as the MANIPULATION OF ABSTRACT PLATONIC FORMS. I do not understand this realm where computers are "physical objects" you manipulate with "screwdrivers". I would prefer to use Math to translate my thoughts directly into action, as if I am casting magic spells

Okay thank you all for explaining. I have one more question: Is there actually, like, a difference between drive vendors. Like if I pick WD vs Samsung vs Lexar (vs… "crucial"?!) will it ever make any difference

@mcc Their firmwares have different bugs (I.e. the secure erase function might not work). And of course 1000 vs 1024 for size. From the OS perspective they’re interchangeable. They might have different r/w speed, and MTTF/MTBF, and maybe a different percentage of spare flash cells. I usually add drives I’m interested in to the compare list on skinflint.co.uk/?cat=hdssd&xf= for easy comparison.

@schrotthaufen wait wait who defines tb as 1000 and who defines it as 1024. is this documented somewhere

@null_aleph yeah but uhh if they say KB does that actually mean KB or does it mean "KiB but we wrote KB"

@mcc I mean if they put down KB, but meant KiB... That's on them?

@null_aleph or on the store that created the product page :(

@mcc I am not super fond of Canada computers; I have had issues with them here in Ottawa. Also stock issues and hostile web user interface.
I think the last NVMe drive I bought from them was a Corsair? I'll take a look; contrast with their listed stock and go off of the model#

What kind of usage case are we talking about? Are you expecting a LOT of read-write events?

Sorry for the wall of text.

@null_aleph i dunno i just want like… a computer that is good

@mcc harddrivebenchmark.net/hdd.php
Benchmark (KIOXIA/TOSHIBA, 256GB, Type 2280)
harddrivebenchmark.net/hdd.php
Last one I got. (Corsair MP600, 2TB, Type 2280 w/heatsink)

I've had no complaints on the performance of the drive. The super high-end ones may not fit inside of some laptops (chonky heatsink), so be wary of form factor variations.
