    Anyone know where the new fast SSD in the 15" can be found to buy separately? I'm pretty sure it's a Samsung unit? Any help appreciated!

    Well, as far as I know, at least for the moment you cant. The HD is a custom design just for the rMBP that no other SSD will fit into. It is possible that down the line someone like OWC may release harddrives for these rMBP's. But as of right now there is no way to upgrade it, unless someone has one they are willing to scrap.

    Your only bet would be on the 2nd hand market, or an AASP who is willing to sell you one. You would probably wanna get the model number and Apple Part number though (I don't have either).

    I have just been looking for a bigger SSD for my nMP and I have had a tuff time finding any good deals.

    Considering Apple has been using the same PCI connector for almost 2 years and OWC still hasn't released anything, I'm doubtful we'll see anything soon.

    Ya, Maybe we will get lucky but its hard to say. While I love apple they have made any MacBook a painful purchases because your stuck with what you get. Ram, HDD, ect... Max it out if you can, or at least make sure you absolutely wont regret your configuration in a few months. I suppose we can at least be thankful MacBooks have amazing resale value if we had to sell one to upgrade to a different one lol. But this issue is why I bought a 2015 15in MBP and am returning if for a different configuration. Innovation at the cost of customization. But I do love me some Apple :)

    They don't exist. Samsung PCIe SSDs are not available for purchase in the open market officially.

    Besides, the Samsung PCIe SSDs in Macs are a custom, proprietary (non-M.2) form factor.

    The late-2013 and mid-2014 ones use XP941-based SSDs, while the early/mid-2015 ones use SM951-based SSDs.

    Your only choice is to go to eBay for such SSDs pulled off other Macs, or siphoned off the supply chain by some unscrupulous workers.

    Other than used on eBay, I don't think it's happening. Question: now that the 2015 MacBook Pro and Air are using 4-channel PCIe SSDs, is the connector the same? What happens if you (try to) plug the SSD from a 2014 rMBP into a 2015 rMBP, or vice versa?

    The form factor and connector is the same between mid-2013 Airs, late-2013/mid-2014 rMBPs and early/mid-2015 rMBPs. However, the ones before 2015 use slower XP941s while the 2015 ones use the faster SM951s.

    Among the XP941s, 4 lanes are enabled only with a 1TB SSD. Among the SM951s, 4 lanes are enabled across all capacities.

    I have a Macbook Pro A1398 which is a 15" Retina Mid 2014 model (11,2). Can I just say that there are two many different ways of identifying a Macbook, they need one consistent method.

    I digress... I'm looking to upgrade the hard drive in it form the 256gb to a 1tb, but I'm worried about spending $900 only to find out it won't work.

    This is the one I want to buy

    Can anyone point me in the right direction, or possibly let me know if this will work, and best of all provide a testimonial of it working. Also, would I have to get any adapters, or would it work out of the box?

    Thanks,

    you wont get the 2gbps speeds in your 2014 model. That's only for the 2015 model.

    Why not? The chipset/motherboard/CPU are presumably the same in both systems. I see no reason why it wouldn't work.

    Understood and I can live with that, I really need the space though.

    Given that I wont get the speeds (although nikhsub1 belives otherwise and I hope he's right), can I just buy it as is and plug it in? Do I need any adapters, heatsinks, etc...?

    Thanks,

    Update: I bit the bullet and bought it. I'll follow up when I get it and install it.

    What about XP941 512G and XP941 1T? Is there a big difference between them,also mean between 4 lanes and 2 lanes
    Because mine is 15 rMBP late 2013 with 512G(PCI*2), and wondering shall I change 512G to 1T(PCI*4)

    The chip which control 4 lanes or 2 lanes ,is it on the SSD or on the motherboard?

    There is.

    The XP941 512GB gets 720-750MB/s in both directions, while the XP941 1TB gets around 950-1000MB/s in both directions.

    On rMBPs, 4 lanes are available for the SSDs. On iMacs, only 2 lanes are available regardless of what SSD you use, because the other 2 lanes have been occupied by two extra USB ports and an Ethernet port. Same story for the Mac Mini.

    Among XP941s, only the 1TB is 4 lane. Among the SM951s, all capacities are 4 lane, but the 128GB operates at only about 600-700MB/s in writes due to the nature of NAND flash writing at smaller capacities.

    In my system information
    The Apple SSD Control is PCI*2 because of the controller is on the 512G SSD?
    What about if I replace 1T in the machine, will the Control be PCI*4?

    OK
    A friend of mine is selling his 1T SSD(PCI*4) which pulled out form his Mac Pro. It looks like my rMBP can use it...

    I wouldn't trust Taobao all that much. I've been ripped off once before.
