    I am new to mac...I have been setting up and running my MBA for the last 2 to 3 weeks...

    I need to have an SD card permanently connected to my MBA as i have a lot of sensitive data that needs regular backups throughout the day when i am not connected to my network backup device...

    I took my SD card out of my Windows laptop, inserted it into my MBA only to discover that it does not go in all the way...this will not work for me as I will definitely break the SD card at some point during the day / week as I travel from client to client...

    Therefore, does anybody know / have a way of keeping a micro-SD card [as clearly and SD card will not fit] into a MBA such that it can be left in on a "permanent" basis.

    Thanks in advance,


    Joel

    I have frequently considered switching back to the 13" version for just that fact! No doubt a month after I do, Apple will introduce an 11" model with an SD card slot.

    There have been a few weeks worth of delays already while the manufacturing process was being sorted out... they originally asked for $11,000 if I remember right, but received somewhere along the lines of $380,000. Steve and Piers(sp?) have been very upfront with the delay issues and have ironed out all the wrinkles. They could have started shipping at the end of this month if they wanted but with the holidays approaching, they didn't want to complicate logistics apparently.

    Looking at microSDXC storage, seems like 64GB runs ~$50-60. Does that sound about right? Throw in $35 for the nifty mini drive and that is a great method to increase the storage on the MBA for a fairly reasonable price. Obviously you could go external USB 3, but that wouldn't be as sleek as this route.

    Maybe a silly question, is it possible to run games from the SD card?

    Agreed though the key issue is not sleekness but rather portability and the Nifty Mini Drive fits the bill...

    Agreed. I meant sleek being both sleek and not having to drag an external drive around and having other cords connected to the MBA. :D

    I can't answer that directly as I have no experience with that. However it is worth nothing that a high speed micro sdhc card is only going to get you ~30-35 MB/s from what I have seen (class 10). I have also seen extreme class 10 that get ~45-50 MB/s. A typical hard drive is going to get you around 140-150 MB/s and a SSD 250-500 MB/s. So can you run a game off a SD card that gets you 30-50 MB/s? I would say probably not as the SD cards were never designed for that. Better to use the SD card for extended storage and pull the files off to your MBA when you need to use them/access them.

    Ah, I saw a video of someone running off USB pretty well, but i reckon USB 3.0 flash drive would most likely have a much higher transfer rate?

    USB 3 is rated at 5 Gigabits per second which comes out to 640 MB/s. But I have heard real world numbers are closer to 250 MB/s. USB 3.0 is definitely faster than a SD card unless there are some newer SD cards that I have not heard about?

    Correct, SDHC/SDXC cards have lower bound speed of 10 MB/s (Class 10). A subset of these SDHC/SDXC cards called UHS-I go to 50MB/s, UHS104 to 104 MB/s. Even the newest standard, UHS-II has a theoretical maximum of 312 MB/s which is slightly less than half of USB 3.0 theoretical maximum.

    I have some Sandisk Ultra class 10 SD cards and they only run about 15MB/s through the SD slot on my Mac

    Interesting. Any idea what they run at in real world speeds?


    I think it just depends on the particular class 10 card as the speeds vary widely.

    Class 10 means it is 10 MB/s minimum.

    So if speed is the bigger concern here rather than convenience it would be better to go with a usb 3.0 drive rather than an SD card?

    Only problem is usb 3.0 drives seem to be quite expensive

    Sure. I was just stating that within class 10 the speeds vary greatly. From what I have seen, the more reputable companies like SanDisk, PNY...etc. tend to have faster speeds than some cheaper not as well known offerings.
