    Hey guys,

    I purchased a used mid 2015 15'' rMBP (still under warranty). I ran some speed tests on SSD. I seem to be getting in the range of 730mb/s for both read & write. Isn't this slow? I was under the impression that mid 2015 mbp ssd is twice as fast as what I am getting. SSD size is 512 and processor is 2.2Ghz. I am paranoid that the previous owner may have swapped the SSD with an older version of it.

    Any feedback would be appreciated, thank you.

    Hurm, that does sound a little odd. Especially being the 512GB model...

    Could you do me a big ol' favour? Click the Apple logo and hold Alt to change About this Mac to System Information, then open that. Click 'Storage' on the left hand side. Where it's got Macintosh HD, it should have the media name for the physical drive. Please could you advise what that is?

    There might also be additional drive information in PCI/NVMExpress, so feel free to copy that stuff in too.

    Basically we'll be trying to identify the hardware information, to see if it's an Apple OEM SSD, or an aftermarket one. :)

    thanks for replying back quickly :)

    Available: 483.59 GB (483,594,285,056 bytes)
    Capacity: 499.06 GB (499,055,067,136 bytes)

    Device Name: APPLE SSD SM0512F
    Media Name: APPLE SSD SM0512F Media

    There's nothing under PCI and NVMExpress. It just says "this computer does not contain any PCI cards/NVMEpress devices"

    How do you swap the SSD on a mid-2015 Macbook Pro? I thought whatever SSD Apple included is what you got for the life of the machine.

    Wait, ignore what I just said before... let me investigate this further.

    EDIT 2: Righto, APPLE SSD SM0512F can refer to anything from 2013 model SSD to 2015. Can you copy/paste any other modifiers?

    We'll need one with the serial number/model/revision of the SSD. On a SATA system, this is located in SATA/SATA Express. Not sure where it'd be on your one... really sorry, you might have to dig through a few of the hardware bits and pieces.

    There should be the chipset listed at the top and then the information in the bottom would look something like the below:

    Hitachi HTS545050B9A302:

    Capacity: 500.11 GB (500,107,862,016 bytes)
    Model: Hitachi HTS545050B9A302
    Revision: PB4AC60Y
    Serial Number: 110919PBL400P7G94SJV

    My apologies again, I don't have a rMBP to hand at the moment!

    - All Apple MacBook Pro SSDs fron Mid 2013 to Mid 2015 are cross-compatible. But the earlier ones will be slower.

    Further, OWC makes third party drives which are even slower.

    - Based on some Googling, APPLE SSD SM0512F seems to be a Late 2013 part.

    Looks like it! It's mentioned in a few articles with 2015 models too (I'm just skimming through the search result titles though...)

    Hopefully we can definitively confirm once we get a touch more information. It's not looking good though, is it :(

    You're a hero buddy. Thank you for sorting that.

    Bad news I'm afraid. The UXM2JA1Q revision is the SSD from the Late 2013 Retina model. Unfortunately they must have swapped it out at some point. What a thieving grub. I'd get out the baseball bat if you haven't already.

    - That's definitely an older one. A 2015 should show PCIe x4, not x2.

    You are completely sure you have a Mid 2015 machine, correct?

    I had a feeling that it was an older one. Can't trust people these days, can you?

    Well, "about this Mac" shows it's mid 2015. Please see attached screen shot. I'm guessing the SSD controller info (PCIe x4) is on the SSD and not on logic board or other hardware controllers and such.

    Thank you for the help guys, really appreciate it.

    :( I'm really sorry Msalman, I really am.

    Any chance of a refund? May I ask where you purchased it from, or if you purchased it recently? If you got it from eBay there might be a hope of starting a complaint and get a refund from PayPal.

    thanks man, this really stinks because I was planing to use it for 4-5 years. I bought it last night and offline through Craigslist kinda website. Paid cash so now it all depends on the seller whether he gets back to me or not.

    Maybe he wasn't intentionally trying to screw you but rather, he had sensitive information on the hard drive and rather than wipe it, he replaced it with another hard drive for security purposes. Maybe he didn't know any better?

    Sorry to hear about this. Terrible.

    But, I appreciate the post because it got me to check my system. Mine performs a 1.5 GB/sec and if you are interested I can post the information from my machine.

    Doubtful. It's a big ol' job to replace the SSD. If they had the capability to do that, they'd certainly have the knowledge for how to securely wipe a drive.

    Definitely a scammer. I've got nothing but sympathy for the OP.

    No, it's not. Replacing the SSD takes 5 minutes and most of the time is spent removing and reinstalling the bottom case.

    Point taken. But that doesn't discount they'd need a pentalobe screwdriver and a bit of knowledge... you're probably taking the wrong end of the argument. I'm trying to say it was a deliberate/thought out scam. I can't imagine many circumstances in which this would be a simple mistake or oversight.

    Haven't heard back from the guy and I doubt he will reply back. I am gonna try to sell it, take my loses and look for another one.

    Please do because it would help, thank you.

    Honestly, I doubt it's a scam. It takes too much time and effort to buy another SSD and sell the old SSD for a few extra bucks.

    More likely, the laptop came with a smaller SSD and the previously owner bought the cheapest 512 GB SSD that is compatible.

    Yeah in retrospect that's probably the case. Info online based on S/N seems to indicate it wasn't a BTO and came with 256GB from stock.
