Toshiba FlashAir W-04 vs Eyefi Mobi Pro

sdcards

Life has many existential questions and then some simple annoyances: why is the built-in WiFi in so many cameras so terrible? My Sony a6300 requires QR codes, wireless connections, and clunky built-in applications (as well has having the even more kludgy Sony PlayMemories application on the receiving device). Sometimes the simplest solution is not proprietary, and that is where we come to wireless SD (actually SDXC) cards.

Eyefi

Eyefi was a Finnish company that pioneered the idea of the wifi-enabled SD card. The idea was to make a small card that had a short-range 802.11 connection that could interface to a computer. Before long, the focus became transmitting to handheld devices.

In theory, all wireless cards count on the tolerance of a camera for staying powered up until disk operations are finished. In practical terms, this means that the wifi component in the card is activated by reading or writing a certain amount of data to the card, and the camera does not go to sleep until the transmission is complete (or some number of minutes passes, and the camera says “enough is enough!”).

Eyefi was not a tremendously easy system to set up on a handheld because it installs a WiFi profile (ID and password). This required you to enter a code on the back of the box into the handheld application, have your phone install the profile, go to WiFi settings, connect to the Eyefi card (assuming it is powered on) and then activate the Eyefi Mobi application.

From there, and assuming you were out in the wild, and your handheld could not see any other networks to which it could auto-connect, it would automatically connect to the Eyefi card. You would have to launch the Eyefi app to get transfers to start.

In general, the Eyefi setup worked (and works), except for a few caveats:

  • It is difficult to reconfigure the cards for a new device if you lose the activation code, and it is not straightforward to recover them (you used to have to email Eyefi customer service).
  • The configuration on the pro cards (transmit raw files and video or neither) required work with the hellishly ungainly Eyefi desktop application, which was a solution looking for a problem (if you are at your computer, why would you need to wirelessly transmit data to it?)
  • Eyefi cards were (and are) pretty hard on camera batteries.
  • Eyefi cards never got fast enough for intolerant cameras like Leica Digital Ms, especially the Typ 240 and its siblings, which really don’t like cards that can’t do at least 60mb/sec write speed (which generally means a 90mb/sec read speed – what they show on the box as the “speed”).

The Eyefi Mobi and Mobi Pro cards were a bit easier. The orange Mobi only transmits JPGs (you need to plug it into an SD reader to get RAW), and the black Mobi Pro would transmit both. But the speed still maxed out at Class 10, still not fast enough for a Leica, where sometimes they work, sometimes they don’t, and when they don’t, they lock up the camera until you remove the battery.

Eyefi’s reorg, Toshiba, and Keenai

The Eyefi situation, oddly, changed for the better with the reorganization of the company. The technology end (the patents) went to Toshiba. Keenai took over the software end and designed a (free) mobile application that far more reliably connected to the card and downloaded pictures far faster. While on paper, the deal between the companies was cross-licensing, the reality is that Eyefi cards are out of print.

Toshiba

Toshiba took over with its FlashAir series where Eyefi left off. True to Japanese corporate form, it put out its own clunky (and frankly indecipherable) handheld application. FlashAir. To its credit, the application allows you to see thumbnails (JPG and pink boxes for RAW) that allow you to selectively pull (as opposed to having the card push) files. This avoids the usual wait for the good shots while the card pushes all of your bloopers to your handheld.

The FlashAir W-04 (the current model, for some reason only available in Asia – in the U.S., you get the W-03 – but you can buy the W-04 all day on Ebay…) is in many ways better than the Eyefi Mobi Pro.

First, it skips the activation codes and profiles and lets you just punch in an 8-digit password (which you can change via the handheld app) when you connect to its wireless signal. I would not recommend changing this password because the risk of someone in your immediate proximity stealing your images is far smaller than the risk of forgetting the password and bricking the card.

Second, on Keenai, it is zero-configuration. It sees the phone is connected to a FlashAir card, and then it goes to town downloading everything (JPG and RAW). I think the assumption is that your phone will only be connected to one card at a time.

Third, the Toshiba cards seem to eat batteries less, although the effective range seems shorter. I am still testing this, but that kind of tradeoff would not at all be surprising.

 

Finally, the W-04 transfers about twice as fast as the Eyefi over WiFi, and its card write speed (UHS-3, which I measure at 63.3Mb/sec write speed) is high enough even to be reliable with the finicky Leica Ms. This actually makes them useful even when you don’t need WiFi connectivity. Speeds (as tested by me through the iMac 5K’s built-in card reader)

  • Flashair W-04 (64mb/sec write, 88mb/sec read)
  • Eyefi Mobi Pro 32 (17mb/sec write, 19 mb/sec read)
  • Eyefi Mobi 32 (18mb/sec write, 19mb/sec read)
  • For reference, a Samsung Pro non wireless card (rated 80/90) runs at 64/88.

…so as you can see, “Class 10” covers a lot of territory (basically 10mb/sec and up)

Unsolved problems

There are two last annoyances.

One is that iOS devices are hostile to the idea of strict priority lists for wireless. At home or work – where your handheld would be connected to a permanent network, you would want EyeFi or FlashAir cards to trump the local Wifi when they are active (since they are only active for shooting or file transfer). This is not a problem inherent to the cards themselves, but it makes using them less fun.

Second, wireless host programs like to store downloaded images in their own purgatory rather than dumping them all directly into your iOS photos storage. This means that you end up storing two copies of some (or all) pictures, eating into onboard storage. This actually is within the province of Keenai to fix.

Conclusion

With the maturation of wirelsss SD card card technology and of editing programs like Lightroom CC mobile, you can now actually get more done in more places. And yes, they even work with Sony cameras.
