I purchased the Transcend Expresscard RDF1 for my Macbook Pro, intending to use it with a 64GB SDXC card for more storage. I selected this product primarily because it will hold the SDXC cards flush into the Macbook, and not sticking out a little as with some other similar products. When I received the Expresscard, I quickly installed it in my Macbook. It slides into the express card slot and locks into place. To lock it into place you have to use the edge of your fingernail because there isn't much room for fingers once it gets almost all the way in (at least, not for my fat fingers). Once installed, it was a snap to slide the SDXC card in, which also locks into place. As advertised, it is completely flush when installed, so it is possible to leave the card in the Macbook when traveling. To remove the SDXC, just push the card in a little and it pops back out about a third of its length. Same thing for the Expresscard, but you have to use the edge of a fingernail as described above.

At this point came my only complaint about the unit. Nothing happened once I got the two cards physically installed. I expected the drive to appear in my OS X finder but the Macbook resolutely ignored repeated removal and replacement of the two devices. After some effort I located a website on the little cardboard card in the bubble pack, stating in tiny print where you have to download drivers [...]. This done, the drive mounted immediately. I have to say, the card is fast. I cannot tell any difference in speed copying files to the card as compared with copying files between locations on the hard drive. It is noticeably faster than copying to a USB 2.0 device. Now that it is properly installed, I am very pleased and am considering investing in a 128GB SDXC card for even more storage.

Note: I am using a 133x SDXC card.

Card readers are generally lagging SD card development. Grievously lagging. A good deal of the problem is that USB2 just isn't fast enough to keep up with the transfer speeds the faster SD cards can achieve lately. Enter Transcend with this PCIe Express Card reader. With it, you will NOW see the full speed that your cards (probably the ones you've been complaining about) can deliver. Just for example, the latest SanDisk Extreme Pro cards claim 90MB/sec read speed. Well, in the built-in reader in my Dell Laptop (only a year and a half old) they most they'll do is about 15.5MB/sec write and 22MB/sec read. Yikes. In this Transcend reader, they deliver 100% full speed, about 45MB/sec write (yes!) and slightly higher than the claimed 90MB/sec read. Wow. That's seriously smokin fast. I went out with my D300s and shot 200 miscellaneous frames at 6/sec. The camera didn't slow down once. Then I transferred those 200 ~8MB files to a disk on my network server in about 20 seconds. Wow. That's the first time with any reader I've come anywhere close to those speeds. For the few $$ this thing costs, and assuming that you have a laptop that has an available Express Card slot, you shouldn't hesitate to add one of these adapters.

One minor note: The adapter won't be recognized in Windows unless you install the driver first. You have to visit Transcend's site to get that [Amazon won't let me put the URL to the driver here. You'll have to get it from the package insert where it's in rather tiny letters.] and then click on the ambiguous little flag in the upper right corner to localize. The driver sets up in Win 7 in a couple of seconds and doesn't require a reboot.

I just purchased this with the Transcend 16GB UHS SD Card in lieu of ordering a proper SSD ExpressCard so as to seriously upgrade my ThinkPad R52's capabilities.

If you're looking to make it 54mm width and flush, I might suggest the StarTech ExpressCard 34mm to 54mm Stabilizer Adapter over StarTech's first generation stabiliser. While a bit spendy, the ability to have 2 available for other uses makes the investment worthwhile in my opinion. This reader does not require the stabiliser for the ThinkPad R52 at all, but my desire to keep it permanently installed made the decision one of aesthetics.

The clampack that this came in is utterly awesome! I just had to pull the convenient tab to "sardine-can" the back panel off of it. :D

I've noticed that some of the past reviewers have mentioned heat issues. The palm rest above it is slightly warmer, but isn't really all that noticeable with the device idling for extended periods.

.: Technical Information :.

It works out of the box with the vanilla Arch Linux kernel 3.4.4-2 via the module < sdhci-pci >. I think it should work with the earlier kernels of any distro as long as they are compiled with support for the < sdhci-pci > or < jmb38x_ms > modules. The Linux drivers off of Transcend's website support only the 2.6.31~2.6.38 kernels as the < jmb38x_ms > module.
