As much as we all love our iOS devices, there's something that some Android and Windows Phone devices usually have that would be really nice to have on an iPhone or iPad - expandable storage. Some of those devices have an SD, mini-SD, or micro-SD card slot into which you can drop an inexpensive flash card, making it simple to transfer files between devices or store tons of content (photos, videos, etc...) on a removable card. Now SanDisk is bringing some of that flexibility to Lightning-equipped iOS devices with the new iXpand Flash drive (US$59.99 for 16 GB, $79.99 for 32 GB, and $119.99 for 64 GB).
While it seems unique, the iXpand Flash really isn't something new. A few years ago, I reviewed the PhotoFlash i-FlashDrive HD, an 8 GB to 64 GB solution with an accompanying app that added a file system to iOS for storing just about any type of file. The device worked well; in fact, I still use it regularly to move masses of files between Mac and iPad.
SanDisk's solution will have a bit more clout, primarily it's from a company that is huge and well known. SanDisk has a presence in 300,000 retail storefronts, and the company has a 36 percent global revenue market share in the flash drive world, so the brand has gathered both familiarity and trust.
In terms of design, the SanDisk iXPand Flash is much more polished than the PhotoFast solution. The former was a white plastic device with a 30-pin Dock connector on one end and a USB connector on the other, with a USB to Lightning adapter thrown on for the newer devices. Unfortunately, that design meant that in many situations, cases had to be removed from iPads and iPhones in order for the connector to be plugged in.
Not so with the iXpand Flash. It features a sleek metal-looking body with a flexible Lightning adapter that is stowed in one side. Atop the device is the USB connector, protected with a smoked plastic cover.
The whole shootin' match weighs a scant .9 ounce (25.5 grams) and takes up a small volume of about 2.48 x 1.46 x .39 inches (63mm x 37mm x 10mm). It looks good - much better than the somewhat kludgy PhotoFast i-FlashDrive HD - but how does it function in the real world?
The idea behind devices like the iXpand Flash is that regardless of how much space you have on an iPhone or an iPad, chances are really good that you're going to take a lot of photos or videos and run out of storage. To offload those photos and videos, you plug the iXpand Flash drive into your iOS device, use the accompanying free iXpand Sync app to grab the content and store it in a folder or folders on the drive, and then optionally use the USB connector to copy the content to a PC or Mac for backup.
I tested beta versions of iXpand Sync on an iPad Air. When the drive is connected and the app is launched, it presents a clean layout showing a group of folders (ASSETS, Documents, Music, Photos, Videos), Mac and PC executables for SanDisk's SecureAccess V2 software, and a couple of QuickStart guides.
One QuickStart guide shows how to plug the drive into a iOS device, as well as how to interpret the tiny LED on the side of the drive. The iXpand Flash drive does have a battery, and a green LED indicates that it is charged, a red LED indicates a low battery state (in which case you plug the drive into a USB port for charging), and a yellow LED indicates that the drive is being charged.
To move something from your device to the drive, you tap the large red plus sign button at the bottom of the iXpand Sync display. You're asked if iXpand Sync has your permission to access your photos, and your photo library is visible once you give the OK. Images can be viewed by individual photos or by albums.
