Question Are all M.2 NVMe SSDs the same apart from their storage capacity ?

[eco_bach]

I currently have 3 Samsung NVME M.2 (both 950 and 960) 512 GB Pro drives installed.
I am upgrading 2 of these to either 1 or 2TB versions.
There are so many options and brands!

Outside of storage capacity are they all the same in terms of performance-reliability?

Any recommendations?
Thanks!

Just an FYI, the higher capacity drives tend to have higher read/write numbers but not each SSD maker have their strengths and weaknesses.

What is the make and model of your motherboard and the processor you're working with?

No.

Cheap price = low reliability/durability. Some drives also suffer from low read/write speeds. Including when drive is full. Oh, high operating temps as well.

Any recommendations?

My suggestion would be Samsung. Depending what PCI-E version your M.2 slot is;
PCI-E 3.0 - Samsung 970 Evo Plus
PCI-E 4.0 - Samsung 990 Pro

I have 970 Evo Plus as my OS drive and mine is 2TB in size,

990 Pro is currently the best from Samsung,

But if you're looking PCI-E 5.0 drives, then things get complicated.
Crucial T705 is current speed king,

But it has downsides, like high heat output, high power consumption and high price.

IMO, PCI-E 3.0 drive is more than enough speed wise. PCI-E 4.0, while double the read/write speeds, can not be differentiated from PCI-E 3.0 drives in real world tasks. And PCI-E 5.0, double the speed of PCI-E 4.0, is more like a gimmick. Sure, 4x times as fast as PCI-E 3.0, but few MoBos have PCI-E 5.0 M.2 slot and it's read/write speeds are needlessly way too high. (E.g Concorde flew twice the sound barrier limit, yet, most passenger planes are below sound barrier, cruising 700-900km/h.)

The 960 is a later generation than the 950.

What will you be replacing it/them with?
What is applicable to your current motherboard?

 

[USAFRet]

Replacing one or more of those with 1-2TB 970s will give you more space, But no real user facing performance change.

Can't go wrong with Samsung... 970/980/990 series. Definitely time to upgrade from 512GB though!

No reason to avoid some other and long time in business makes like Kingston, KC2000 (PCIe v3) and KC300 (PCIe v4) NVMe drives. A-Data and Lexar also have very good drives. As a BOOT/OS drive, look for RAM Cache and speed, for storage anything goes as long as you have viable backup plan,

No, there will be performance differences due to internal construction.

For example from your list, the Kingston 2tb unit is not a great performer, from the partpicker benchmark:

It IS cheaper.

The Samsung 980 Pro 2tb does much better:

Once you get to 1tb size, endurance becomes a non issue.
