SD Cards In MacBook Air.

Black,

What I ended up doing is kind of nifty. I wanted to have permanent storage as well, but I did not want my card to stick out so far as I catch it on things in my travel bag. I found a shortened Micro SD adapter for $8.00 and put a very fast Transcend 64GB Micro SD

card in it. This thing only sticks out of my Air 1/8th of an inch. See below and thanks for the advice!

I did some benchmarking tests on the drive after I got it and found that leaving the card as exFat was a bad idea because of file size limits and the fact that movies can end up being pretty large. I ended up doing exactly as you suggested and have had great results.

1. Macbook Air mid 2012 13" User Guide is not available from the Apple site yet, but the MBA mid 2011 SD card slot can accept an SD or SDXC card. MBA 2012 should be the same.

2. None. You could use a 32GB, 64GB or even 128GB card, formatted as Fat32. Fat32 has some limitations vis-vis HFS+ (e.g., no file > 4GB)

3. Yes. It is storage. However, just like USB sticks, SD cards are intended for temporary storage and transfer of data. I would not use an SD card as a permanent storage solution any more than I would use a USB stick for permanent storage.

The specs for the MBA are here.

I use SanDisk 32GB (30MB/s) SDHC cards in my current MBA and iMacs though other makes will no doubt be just as usable. I've no desire to use 64GB cards.

No idea about your point 3 but I rather doubt it.

Confirming that an 256GB SD card will work with the latest macbook air and previous generation as well. Because they aren't cheap, I was hesitant to purchase this size. The built in slot reads it just find. The only draw back is that it sticks out a 5cm, so it's not ideal to leave in for long travel.

The SD slot is primarily meant for ease of transferring photos but a fast data card can be used for additional storage - but I'd not recommend keeping the card in the computer on a regular basis. For example, my 256GB drive is sufficient for everyday work but when I travel I want to carry more music and video. I have a fast 64GB card that I use to store the extra music and video on. I have a 128GB card that serves as an emergency system and applications drive. I've never had to use it but in an emergency I could boot with that card, and perhaps repair the SSD or if need be use it as a clone so I could limp along until I got home.

But I do not use either card to acually augment my internal SSD as one might add a second drive to a desktop computer.

I downloaded Lion. When the download is complete the installer automatically launches. You can quit it and make a copy. Having done that, I simply double clicked the Lion installer and then pointed to the SD Card - mine is 128GB. It boots up somewhat more slowly than normal...and then I installed my programs. Haven't gotten around to doing it with Mt Lion yet but the processs should be the same.

I don't make it with a clone because my boot drives are all larger than the SD card (and too full) but if I did have a hard drive that had say 80GB or less of stuff on it I could go the clone route.

So, in order to use the SDXC card like 64GB, the card must format in FAT32, and the card won't work on other formats such as ExFat or MacOS Extended Journal? I bought a 64GB Patriot SDXC card, when I formatted in ExFat, the Air won't recognized card. I tried on other Macbook Pros, ExFat worked.

Hi! How are you? The reason why I'm here is to find out more about SDXC support/compatibility info on the macbook air 2012 and how to fix this nagging issue if it's fixable.

I had just bought a Sandisk extreme pro 64GB rated at 95mb/s for my Nikon DSLR. Unfortunately, MBA struggles to detect or mount my card, after a few sweats, it would mount, but then very slow to process and preview the images as "Thumbnail preview". Then, after a few more sweats, you can scroll through the thumbnails smoothly.

Streaming HD videos straight from the SD Slot is butcher chopping the beef. Video lags, stutters, chops, in otherwords, USELESS and a pain in the neck. So you just want to copy all the files to your macbook, and play from there. Copying files from SDXC to my macbook takes forever; writing is also another issue that take much more than forever!

I have a top of the line macbook air 2012 (i7, 8GB, 512) and I always thought it's a versatile reliable computer but now I'm very disappointed. On the other hand, doing the same things on my macbook pro 2010 is seamless. I also tested on my windows 8 desktop to be flawless as well.

Therefore, the memory card is not the problem. It's macbook air's sd slot that's a failure. I never thought spending $2,199 for a super computer would make me stress like this. In addition, the magsafe 2 is another failure in design. It always disconnects just by moving my macbook air from one spot of the table to another. Having it charged while on my lap gets on my nerves when it keeps getting disconnected! I hate Apple for doing this. If only there was a Windows notebook that surpasses Apple's design, I would never EVER buy Apple products EVER again.

My SanDisk 64gb SDXC card runs just fine with OSX Extended Journaled formatting. I just leave it in the computer. No issues in four years, so it works fine as "permanent" storage. Writes very quickly, usually a few seconds lag to read the drive initially, then it works fine. Going up to either a 256gb this week, or the Transcend ones designed to not stick out from the side of the Air.

I wanted to ask you, do you have issues with maximum file sizes, using the extended, journaled settings with your 64GB Sandisk card?

I was thinking about getting away from the FAT settings?

Also, Does it write large files fairly fast?

I have used the Nifty MiniDrive for a year and no issues. I bought the 4gb version then selected a fast micro 128GB SD chip to put in it.

It flush with the side of my Mac Air.

dwb, how do you create an emergency system and applications drive on an SD card? I know this is off topic, but i am very curious and would like to do the same thing. Do you do a clone?

Why not use sd as second drive and backup via time

Machine to external
