Average Reviews:
(More customer reviews)Before purchasing Lexar's new Expresscard CF reader, I was skeptical that this model would be any better some of the previous attempts by other vendors. These devices historically have worked very poorly, on Mac notebooks in particular. Many of the reviews mention kernel panics after merely plugging the card into the slot!
Lexar's reputation for quality products led me to finally try to replace my Firewire 400 CF reader (also by Lexar) with one of these, and so far I haven't been disappointed.
I did an apples-to-apples comparison of my new Expresscard CF reader versus the Firewire 400 (chained via my Iomega Ego triple interface external HD to the MacBookPro's FW 800 port). My Transcend 133X 32GB CF card contained 548 Canon RAW images weighing in at just under 15 GB. For this test, they were copied to my MBP's internal SATA drive.
The results? The Expresscard reader copied these images in 6:57 (or 35 MB/sec average throughput) versus the Firewire 800 reader in 16:57 (or 14 MB/sec average throughput) for an improvement of 2.5X!
Anecdotally I'd say performance of the Expresscard reader is on par with the Firewire 800 card readers I've used, but I've only got one FW800 port on my MBP, which is often being used by my external HD. Unless you dedicate your Expresscard slot to some other purpose (or don't have one), I see no reason to buy a slow, bulky USB or Firewire card reader with this faster, less expensive option available.
