Hi,
I have a macbook air 2013 ( 1,7 GHz Intel Core i7, 8 Go 1600 MHz DDR3).
What is best for performance: using the usb with a USB 3.0 device or using a sd card?
Next question: what's the format for performance: fat, exfat, mac os? I don't intend to share usb Key or SD key with other devices (except my iMac.
Thanks to anyone who has experience and can share info on this.
MacBook Air (13-inch Mid 2013), Mac OS X (10.7.5)
newer USB 3.0 sticks can get 50-100 megabytes
Most SD cards are 56mb-60mb/s., the fastest are 95........it depends on the class of SD card you have in the SD card slot, (class 3,...4...5....6)
In most instances, a high class USB thumb drive is faster than generic level SD cards
format all them for Mac OSX extended journaled if your NOT going to use them in any other device.

I undertand that they both have about the same performance, if they are both usb 3.0 compliant. A class 10 SDXC would have equivalent performance to a usb 3.0 stick. Is that correct?
Yes and no, there are emerging thumb drives that MATCH the max speed of USB 3
such as:
Kingston’s new 512GB and 1TB drives top out at read speeds of 240MB/s and write speeds of 160MB/s, the new Corsair Voyager GT Turbo line of USB 3.0 flash drives have read speeds as high as 260MB/s and write speeds up to 235MB/s.
Amazing... Thanks a lot.
I finally bought a SDXC card by Kingston. Since it's formatted using exFat, today, I regret it because it causes a conflict with Spotlight's index under Mavericks. I can't index my card now because to stop the problem, the card has to be put on the spotlight confidentiality exclusion list. Too late... Just wanted to let people know.
Reformatted the SDXC card using apple's format system. All problems have disappeared. Avoid exFat with SDXC cards.
USB Key or SD card for macbook air 2013?
