HP 17-cb0002ca, M.2 PCie or SSD only?

[Hagar800]

I have the HP 17-cb0002ca, how do I tell if the M.2 is PCie or SSD only?

And if its PCie, max speed M.2 that would work?

And if its SSD (Bummer) max speed is Max SSD  speeds?

I just got this laptop in like new condition for $420

I think its a SSD.

The product specs for your notebook indicate the 128 GB is PCIe/NVMe.

The M.2 slot is PCIe Gen 3.0 which means that a PCIe Gen 4.0 NVMe SSD would not run at its maximum advertised read/write speeds.

This chart provides the maximum transfer speeds from the various generation PCIe slots:

Well that was outstanding, thanks.

I guess I just don't understand the newer configs.

Wonder why crucial recommended a Gen 4?

And all those settings, when is it running the 2 lane or 4 lane?

Is the 1 tb M.2 I ordered going to run in the faster 4 lane?

This made no sense to me.

1 TB, PCIe, Gen 3 × 4 L57387-001
512 GB, PCIe, Gen 3 × 4 L57386-001
512 GB, PCIe + 32 GB Optane memory L57388-001
256 GB, PCIe, Gen 3 × 4 L57385-001
128 GB, PCIe, Gen 3 × 2 L57384-001
16 GB, PCIe, Gen 3 × 2 Optane memory module

and what is Optane memory?

Thanks for taking time with me.

You're very welcome, Dave.

Crucial also recommended PCIe 3.0 drives for your notebook as well (the P3).

I would imagine your notebook's M.2 slot would be PCIe 3.0 x 4.

You don't want those NVMe SSD's with onboard Optane memory.

I don't even know why they bothered trying to accelerate an already fast enough NVMe SSD.

Intel Optane memory was originally developed to accelerate the mechanical SATA hard drive.

This link will tell you all about Intel Optane memory.

This Intel NVMe drive has the Intel Optane memory integrated on the drive's circuit board.

512 GB, PCIe + 32 GB Optane memory

Expensive and not worth it.

This is a plain Optane memory drive accelerator that would have been used to accelerate your notebook's 1 TB 2.5" mechanical SATA hard drive.

16 GB, PCIe, Gen 3 × 2 Optane memory module (only uses 2 of the 4 PCIe lanes).
