    G'day all,

    *I did already post this over at Tom's hardware, but everything I ever post there seems to just get buried with no responses, so I figured this, being a more Apple-centric forum, maybe you guys could help.*

    I am looking into buying the base level iMac (late 2013 27in) and then upgrading it myself. I have looked into the whole "DIY AIO" thing with the Gigabyte motherboards and the Loop chassis, but they dont offer the power that the iMac does sadly. I am planning on upgrading the CPU, RAM, and storage. Here is where I fall into some confusion:

    I recently have been reading a ton of the replacement guides on the late 2013 27in iMac over at ifixit. Their teardown of the iMac https://www.ifixit.com/Teardown/iMac+Intel+27-Inch+EMC+2639+Teardown/17828 shows the pcie connector free on the board if you only order a HDD option (what I am planning to do). In the summery bullets, they quote: "Budget-minded folks now can add a second hard drive to the base iMac because the Fusion Drive connector is no longer missing from the logic board." However, this isn't very clear on what kind of hard drive. I realize Apple and everyone says "PCIe SSD", but what exactly does that entail? Can anyone who knows for certain (maybe worked on one of these) what kind of connector it is? Cause further down in the comments, someone mentions that it is a proprietary connector, in which case an Appple SSD from a macbook air/pro on eBay will be the only thing that will work. Or is it an mSATA? M.2? x1? Which of those are considered "PCIe" when people talk about a "PCIe SSD"?

    I am thoroughly confused by all of this contradicting terminology, and would like to know for certain what works and what doesn't, because if the SSD connector on the board can't be upgraded, I would like to know that before I buy the iMac. If anyone could help clear some of the confusion im having up, it would be greatly appreciated.
    Thanks, and any information/insight is appreciated!

    Oh, and also, I want to replace the SATA hard drive with a 2.5in SSD (probably samsung 840 EVO) and use the original hard drive for backup. However, if given the conditions above on the SSD and I need to order the iMac with an SSD, its not going to have the SATA most likely. After looking at the ifixit SATA cable guide https://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2639+SATA+Cable+Replacement/20252 I'm also having trouble identifying what kind of SATA is used. It appears to split the power and data on the board, but both the board connectors appear to be like 7-pin SATA connectors? Could anyone shed some light on this? I'll link the pictures so you can see the connectors for everything.

    PS: your links are broken.

    Thanks, I fixed them.

    As for the quote from Dan@ifixit, It still doesnt explain to me what is considered "PCIe" and what "M.2" actually is. For example, when I think of "PCIe", I think of x1, x8, x16, etc. that you find on motherboards. Is this that type of "PCIe" interface? Or is it something else? They say it's "M.2 version of PCIe", so does that mean that "M.2" is considered to be a "PCIe" interface (just like the x1, x16, etc.).

    Also, if the SSD used is the "M.2 form of PCIe", does that mean that if I go to newegg and buy a samsung xp941, which is filed under the "M.2" category, will that work?

    Sorry if I seem really confused, I am.

    Its a custom Apple implementation. Only Apple supplied SSDs will work... for now. OWC may have their versions out by now, not sure. They had prototypes in January.

    M.2 is a lot of things: http://en.wikipedia.org/wiki/M.2
    The PCIe you see on a mobo is the standard form factor of PCIe. M.2 is a variant of the PCI Mini Card form factor.

    Ok, that makes more sense now. So apple is basically changing the pin configuration on the board so that it doesnt line up with "regular" M.2 ssd's.

    Sneaky bastards...

    So my options currently are:
    1-order and SSD on the iMac thru apple
    2-buy one pulled from another mac off eBay
    3-see if OWC has any that will work

    Thanks for the help, now I know what I will and wont be able to do myself

    so would something like this work? I know it says macbook pro, but its for the 2013 models, and I would assume that apple uses the same connector across all of their products.

    It won't work.

    The OWC ones are for the early-2013 rMBPs, which use a proprietary mSATA interface.

    Meanwhile, the late-2013 rMBPs and later, along with the late-2013 iMacs and later, plus mid-2013 MacBook Air and later, all share the same proprietary Apple PCIe interface.

    No third-party PCIe SSD upgrades exist for Macs yet.

    Don't forget you could easily purchase a thunderbolt ssd! Just as good as internal.

    Not as fast as a PCIe SSD but certainly fast enough for a SATA SSD.

    Dont all of the external thunderbolt ssd's still utilize an internal SATA drive just connected to an external thunderbolt interface? Therefore your still limited to SATA speeds.

    You got that straight.

    The only way to get PCIe speeds is to BTO the iMac with an SSD from Apple itself.

    OWC and Transcend upgrade kits won't work. Those are mSATA blade SSDs for the Ivy Bridge Macs (late-2012 iMac, mid-2012+late-2012+early-2013 rMBPs).

    Does anyone know the part numbers for the Apple Late 2013 27" iMac PCIe SSD's are?

    256GB: SM0256F (rMBPs also use SD0256F, which is substantially slower)
    512GB: SM0512F
    1TB: SM1024F

    The late-2013 iMacs, late-2013/mid-2014 rMBPs, mid-2013/early-2014 MBAs and late-2013 nMPs share the same type of proprietary, non-M.2 PCIe SSD.

    iMac late 2013 27in PCIe ssd and form factor questions

    The possible damage cost of what you plan to do is way higher than just order what you need if you desperately need them. If you search for low cost high specs modifiable computer i'd suggest build a custom pc and get a great monitor so you can customize it or you can even hackintosh. If you can do it i respect however i would never take a new imac apart. Peace

    These are not for sale.

    Officially, they can only be obtained from Apple.

    However, you may be able to find these parts 'pulled' off other Macs on eBay.

    These are the trashcan Mac Pro PCIe SSDs.

    They may fit into the iMac, MacBook Air or retina MacBook Pro. but I wouldn't bet on it.

    SM0256F, SM0512F and SM1024F from the MacBook Airs (mid-2013 and early-2014) and MacBook Pros (late-2013 and mid-2014) will definitely fit.

    I max out everything when I purchase online, so that I never have to have the hassle of opening up my Macs to upgrade parts.

    It's a custom SSD that runs off of PCIe in a Blade form. See 2013 MBAs, and late 2013 rMBP's for what they look like (also found in Mac Pros).

    someone told me......

    PCIe is an SSD, PCIe refers to the connection standard. Older SSD's used SATA connections, but the PCIe connection is newer and faster.

    so is it worth getting? and is their any errors i should be worried about?
