[Moomin__]

I have a hp laptop 15-da1074TX, i want to know whether it supports m.2 nvme or ssd wd blue SN580?

I installed software crystal disk info to check... it shows interface ATA, and Transfer mode Sata/600.

Hi:

Your notebook has a M.2 SSD slot that supports both NVMe and SATA SSD's.

NVMe SSD's have faster read/write speeds than SATA SSD's have.

Below is the link to the service manual:

HP 15 Laptop PC Maintenance and Service Guide

The WD Blue SN580 will work fine but not at its maximum advertised read/write speed, because your notebook's M.2 slot is only PCIe Gen 3.0.

But when i add my system on crucial website for compatibility, it recommends nvme gen 4 ssd, why?

[Paul_Tikkanen]

Because PCIe Gen 4 SSD's will also work in your notebook.

If you looked at the entire list, they also offer the Crucial P3 model Gen 3 SSD's too, why?

I don't understand why you don't understand what I wrote the other day..."The WD Blue SN580 will work fine but not at its maximum advertised read/write speed, because your notebook's M.2 slot is only PCIe Gen 3.0."

Sorry, but I can't help you anymore than I already have.

Sorry to bother you sir, what i mean  is if i buy gen 4 will it give me same speed as gen 3 on gen 3 pcle slot, or will it be slower than gen 3, because gen 4 is costly than gen 3, so there is no point to buy it if it runs slower or same as gen 3.

All I can tell you is that the maximum speed you can get from either a Gen 3 or Gen 4 SSD from a M.2 Gen 3 SSD slot is around 3,500 MPBS.

Naturally, if the PCIe Gen 3 drive you want to buy has slower advertised read/write speeds than 3,500 MBPS, that is as fast as it is going to run at.

In the matter of the WD Blue NS570/580 drives, since WD no longer makes the SN570, I have found at least in the USA that the newer WD Blue SN580 Gen 4 actually costs less than the WD Blue SN 570 Gen 3.

It doesn't look like you can even buy the SN570 on Amazon, India anymore.

Thank you for detailed info and being patient!

You're very welcome. 

No matter what generation NVMe SSD you decide to buy, the performance will be much, much better than the 2 5" hard drive is giving you.

Prepare to be amazed.
