    Sorry Bree understood
    That's OK, I just didn't want this thread to drift. The OP wants to learn all about PCIe/NVMe M.2 SSDs.

    Removed 2nd "Robot Check" Amazon link.


    Yeah, I've been working with HDD's for years, swapping, upgrading, backing up, all with impunity. SSD's is a new kind o' critter to me LOL. I've been aware of 'em for years, just never owned one.

    bobkn, thank you for the spec sheet. I can't find mention of NVMe on that document either. However, I do find mention of it in:

    -HP's Knowledge Base Product Specs (under Internal Storage).
    https://support.hp.com/us-en/document/c06469139

    -Various pictures online. Tag looks like the one on my SSD, but, at the time, I didn't specifically look for "NVMe" on mine. Didn't even know what that was a few days ago LOL. https://www.picclickimg.com/d/l400/p...JTNG-8310A.jpg


    What I can't find is the number of data lanes being used by this SSD. Not obvious in my computer specs, the SSD spec sheet, the SSD label, or seller's write-ups. I'm assuming 4 lanes, but 2 lanes might account for the low read rate you noted? The Intel H370 Chipset on the motherboard is capable of x1, x2, x4 lanes.:
    Intel(R) H370 Chipset Product Specifications

    Might be contacting HP with the lane question unless there's an internal diagnostic I don't know about. Even a 3rd party app is fine LOL. Once the number of lanes is determined, I feel I can start looking up SSD alternates that aren't SK hynix LOL.

    Anyway, any help on lane determination would be appreciated.

    You could try Crystal Disk Info (CrystalDiskInfo – Crystal Dew World). I suggest the .zip version (no installation). That seems to get the significant parameters of the drives. For example: it tells me that my C: drive is a PCI-E 4.0 X4 NVME drive. (All correct.)

    About 1/2 step ahead of you, but in a different direction.

    In a last ditch effort before nitey nite time, downloaded HWiNFO64. Verified this is NVMe, PCIe is generation 3, but looks like only 2 lanes.


    From the PCI Bus section for the SSD:
    Maximum Link Width - 2x
    Current Link Width - 2x

    From the Drive section for the SSD:
    Drive Controller - NVMe (PCIe 2x 8.0 GT/s)

    Seems to indicate 2 lanes. But, I'm tired and haven't explored very far in this new info app.

    Does the SSD (let's assume built as 2 lanes) determine the number of lanes from the computer it needs? Or, if I drop in a 4 lane SSD, the computer will negotiate and give it 4 lanes? Hope that makes sense, but I'm done for the day LOL.

    Thanks, again, for your time.

    Good advice above. When you have shortlist, I always total the Amazon poor 1 and 2 star reviews and look for any common problems.

    Not sure if it has been mentioned, but you need to be concerned with "keys" when shopping.

    You'll see "M-key" drives and "B-Key" drives and I think some that are both. It refers to the details of the port into which the drive fits, including the notches and copper contact points around the perimeter of the drive.

    M-key is most common. If your ports are M-key, you need an M-key drive. Those details should be mentioned in the finer print of the drive specifications. Consult your motherboard spec details to see if the ports are M-key.

    The 2 lanes bit explains the relatively poor transfer rate spec. (4 lanes would give a sequential read spec more like 3000MB/s.)

    I believe that if you inserted a 4 lane (X4) M.2 drive, the PC would use 4 lanes.

    Crucial offers both NVME and SATA M.2 driver for the machine: Memory RAM & SSD Upgrades | hp - compaq | pavilion tp01 series | Pavilion TP01-0034 | Crucial.com

    That's a pretty reliable indication of compatibility.

    For a great info source and some useful intro tutorials on underlying technologies (check the "Beginners" tab at top of page) visit Les Tokar's TheSSDReview website. You can spend hours getting familiar with this stuff there, and Les and his team do a good job of tracking what's new and noteworthy.
