    Seeking advice on how best to utilize the ports on a 2015 15" MBP to get SSD speed for video editing. I'm still under Apple Care and assume (correct me if I am wrong) if I swap internal SSD I void?

    So, my only other option would be fast SD cards, SSD connected to either the USB or the TB2 ports.

    Any suggestions as to tactics/strategy here?

    Thanks.

    If only Apple didn't stop making the X-Serve.

    I see what you mean.... Also edited my original post as I was a mess. Thanks.

    I'd love a reasonable and reliable Thunderbolt 2 device. Thunderbolt 2 has been a disappointment. On the other hand, I really don't like the USB-C thing. There are a lot of high-end laptops that still have HDMI, USB-3 ports and sometimes I wish that Apple had included some legacy ports. Yes, even Thunderbolt 2.

    I'm combing through past threads reading posts. I do try before I make a new thread. A lot of back and forth advice saying the 2015 MBP SD card bus isn't as fast as USB 3.0, and that the TB is fastest. Then I see others saying go USB. Hence my reasoning for this thread: maybe a conclusive answer lies buried and so why not bring it out into the light?

    Now, I realize this is a 4 year old machine, but I wasn't so broke I couldn't buy 2018. I actually did, but quickly returned it after all of the horror stories came to be known. I can't afford problems.

    Anyway: don't expect an SD card to run as fast as USB, or USB to be as fast as TB2. So, I suppose I should be hunting for a TB2 SSD, or do I drop another $50 on yet another adaptor? (I hate that idea.)

    Already own an OWC bay from maybe 10-12 years ago. Hate it.

    USB is suggested because it is cheap, compared to TB. I own a TB LaCie rugged already. Wonder if I can tear it down and put in an SSD (as a HDD now)....

    SD read/write is around 95 mb - doesn't really matter what the bus speed is if the device speed is so slow.

    I little further research unveiled one comment in a Q&A section of the Transcend TB SSD product page on Amazon: "The speed of the very fastest SSDs can't even take advantage of Thunderbolt 2. The throughput rate is simply so high in even Thunderbolt 1 that nothing but extremely expensive raided SSDs could reach the Thunderbolt limit."

    If you want the fastest speeds, go with a RAMDisk.

    I was trying to say that but probably didn't articulate myself very well. One interesting thing is I was able to make a YouTube video 1080p in iMove using my cheap Costco SD card as my external, so even though it is limited, it at least works as an additional option, which I didn't think possible.

    One more for the archives: a tester wrote (of the Transcend TB2 portable SSD): "I suspect that speed test results will vary with different hardware configs. I have a 1TB Transcend Thunderbolt connected to my iMac (Late 2015 core i7 SSD). Using BlackMagic Disk Speed Test my Read Speed is about 380 MB/s and Write Speed is about 300 MB/s."

    I'm not editing 4K, just a cheesy bunch of YT videos. Renders for 30, maybe 60 minute shows is where I worry. Read about the RAMdisk. Looking for something maybe a little more stable? Is that right? Not so hip to what they re, actually. A kind of virtual disk methinks. Not what I'm after as I want to jump between the MBP and iMac and eventually migrate to newer machines when they figure out fixes for everything, e.g., keyboards, etc.

    Thx for ringing in. I have Apple Care. If I replace the SSD doesn't that void my AC? I'm making the assumption they will know if I have torn the thing open to replace the SSD, isn't that right?
