But the OP never said it was SATA either. Important for people to know that there is a difference between SATA and the more expensive NVMe, particularly when evaluating whether this is a deal or not.

£117 delivered at Crucial with Quidco @ 3% plus a potential £2.50 Quidco bonus which would make it around £111:

SATA speed not the faster NVMe speed, but a good price nonetheless. Also, it is an SSD not a SDD.

Not every laptop supports NVMe via M.2 though.

This will be great for everyone else though.

That's a fantastic price for a 525GB M.2 SSD.

HOT.

But in all likelihood anyone specifically looking for a 500GB NVMe drive will know the difference, not least because of the huge price difference.

Its hardly the same thing if your laptop uses an m.2 connector.

Also important for compatibility, some laptops can only take sata m.2 or nvme m.2.

That's incorrect. Any nvme supported m.2 slot will support sata drives. Anyone wanting nvme would normally look for the nvme drive..

NVMe is backwards compatible with SATA [edit: as campgareth has correctly pointed out, there are certain exceptions to this]

An NVMe drive will also work in M.2 SATA - it just won't reach NVMe performance (as its constrained by the slower interface) and you may have issues booting off it if its not supported in the BIOS. Still works as a storage drive though.

There are motherboards that have some M.2 slots that are PCIe only although not sure how common it is.
Also not sure if any laptops do this also.
It is extra work to support all the features and in some cases they don't bother.

Sorry but nope. M.2 can carry PCIE and SATA and USB but every one of those is optional, meaning you can't rely on any of them being present just because the connector's there. Check what your motherboard or laptop supports before buying anything.

This is a rehash of the awful mess we had with mSATA and mini PCIE, both of which used the same connector and carried USB because why the heck not. That ended up with some low end wifi cards using the USB interface on a mini PCIE connector since it was likely to be present. They still didn't work everywhere though, because you guessed it, that interface is optional.

*edit* note this has nothing to do with AHCI over PCIE (vs nvme over PCIE) which is actually guaranteed anywhere with PCIE hooked up.

Definitely check - that's a given. I would have thought that most people would have done that already otherwise, they'd be rushing out and buying out some random thing without knowing whether their motherboard can support it!

I suspect it's only really a limited number of circumstances where a certain motherboard has an M.2 slot but has difficulty supporting a M.2 SATA drive. The Z97 springs to mind but most people who own something like that should know what they're doing anyway.

Most people will buy these for laptops and if they have an M.2 slot, they'll almost certainly be able to support a M.2 SATA drive. But you're right - always best to double check.
If you are looking to purchase an m.2 card, chances are you have already seen the socket on your mobo, in which case you can never go wrong in selecting a suitable card because of the physical notches present on the socket/card that restrict incompatibility. Eg: Z97 with M key type socket will support any m.2 card (Sata or pcie) which has M key (or B&M key). OP has posted m.2 B&M keyed drive, so is dual compatible and should work in either keyed sockets.

Folks, I cant make it any simpler than this, If it fits it will work.

B vs M key determines number of PCIE lanes, not whether there's a sata controller somewhere in the chain, or even whether those PCIE lanes are actually connected.

Here's an Asus piece on B vs M keying and here's a teardown of the Dell XPS 13 9343 which uses a SATA M.2 SSD that has both B and M keying despite it not using PCIE at all.

In other words you can't tell what the M.2 connector supports by looking at it. Check the spec sheet.

*edit* huh, looks like that SATA only M.2 connector on the dell's motherboard has no keying, but then an M keyed PCIE SSD would still fit so... yeah this is still bad

Yeah the best examples I've found are laptops that support SATA M.2 not PCIE, or some dual M.2 motherboards where only one port supports both SATA and PCIE, the other is PCIE only.

For less than this you can buy a Samsung SM961 256GB NVME M.2 ssd which although smaller in capacity is MUCH faster.....
