The question nags as I prepare to review TarDisk Pear flash memory expansion. The doohickey is available in 128 or 256 gig capacities for either MacBook Air or Pro. It fits neatly and snuggly into the SDXC card slot, which is required; color and finish match, too. Windows users must look elsewhere, though, and many may be glad to. The tech lists for $149 and $399, respectively. But, hey, the Apple fan club is accustomed to paying more for everything.

I will test TarDisk Pear on my 13-inch MacBook Pro with Retina Display, 3.1GHz Intel Core i7 processor, 16GB RAM, and 256GB SSD. I recently, and unexpectedly, filled up the hard disk with photos and podcast raw recordings. (Hehe, using Chromebooks for so long spoiled me and my awareness of such things.) Doubling storage, particularly with San Diego Comic-Con coming in 14 days, could prove useful for editing audio, pics, and video on the laptop. But is it necessary or contrivance?
