Is there any reason to use one over the other? I hear a lot of people using SD cards for extra storage on their MBA. What's better about them vs. flash drives? They seem a fair bit more expensive vs. flash drives of similar size. Also, will any of the SD cards in the following link work with the slot in the 2012 Air?

The full-size cards in your list will all work (like this one (http://www.amazon.com/SanDisk-Extreme-Class-Memory-SDSDXS-064G-X46/dp/B00D6XW62I/ref=sr_1_2?ie=UTF8&qid=1379385113&sr=8-2&keywords=sd+card+64+gb)), as will all the micro SD cards on the listing that come with adapters. The micro SD cards without adapters will not work.

For the most part, the more expensive SD cards are faster in terms of read/write speed than typical USB flash drives, and that's why they are more expensive. This is more useful for working with things like video and audio files.

The other main advantage is that they don't take up a USB port, which can be in short supply on the MacBook Air.

usb 3.0 is about 3 to 4 times faster than class 10 sd

How about USB 2.0? I have a bunch of USB flash drives that are 2.0 because they're older. What's the speed comparison then?

USB 3.0 is, but the recording media on most USB flash drives isn't, unless you're paying top dollar. Same is true with SD cards.

Even this "USB 3.0" drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16820233561) doesn't even max out USB 2.0 speeds.

Again, depends on the media, but I would bet they're slower. Still, if you already have the drives, you might as well use them.

a person not too careful, had found the SD cards are too fragile for me. Same height of drop in a USB flash disk not ever kill or damage permanently the drive...just my 2 cents.....:o

I bought both a 32GB SanDisk Extreme USB 3.0 drive and a 32GB SanDisk Ultra microSD that I keep in the computer installed in an Apotop adapter/reader..

Both fast, I can't really tell much of a difference between the two, but I know that the 3.0 is really really fast. 5GB transferred in like 1-2 minutes..:eek:

I have a 128gb SD almost permanently sited on my MBA which holds my 90gb iTunes music collection. I don't want to use up a USB port unnecessarily.

For an extra few bucks you can get a "Set it and forget it" storage solution for your MBA. It sits flush with most Macbook Air/Pros and they make a 128GB version which is a bit spendy at the moment but, it should come down in price soon.

I don't get some people. They opt for the 128GB model, then go spend $100 on an SD card.

Ridiculous imo.

Extra $200 256GB Model means an extra 128gb of the fastest storage available in the market, and not to mention it doubles the speed of a 128gb Air.

I don't think you remember when it was a 400 dollar upgrade and when SSD's maxed at 128. Not everyone who has an Air had that option

Relevance to op's question or any of the replies? None.

tl;dr: Get the max SSD you can afford, then get usb3.0 flash storage.

Use the sd card slot for your phones and cameras and so on. 10mbps in 2013 is irrelevant.
we're talking 750mbps speeds with SSD.
USB 3.0 will also go up to 200mbps when paired with SSD.


tl;dr summary: SSD>USB>SD

SD cards are fatally easy to misplace, or to lose outright. Flash drives are easier to keep track of. Some of them can even be clipped to your keychain.

I have a 64GB SD card that I copy iTunes stuff to when I take a trip (my iTunes library is stored on a wireless disk, and while I have a clone of that library on a portable drive, I prefer using an SD card if I'm going to be on battery. Video is enough of a power hog, without adding the extra drain of running a USB drive....)

But after losing my first 64GB card, I would never use one to store my only copy of a particular file. Losing a $80 SD card is bad enough -- losing the data on it would REALLY hurt :(

Another possible solution for you: There are mini-drives available that let you load a microSD more or less permanently in the SD slot on a MBA. These don't stick out of the side the way a regular SD card does, and because they stay loaded in the computer, they're a lot harder to lose than a regular SD card.
