First things first ... I would run as fast and as far away from the Transcend card as you possibly can. It is not a solid state CompactFlash card, it's a MicroDrive (basically a teeny tiny harddrive). That in itself is not a bad thing, both IBM and Hitachi have excellent, proven Microdrives - the 1GB IBM is a standard workhorse. The problem is that they are much more susceptible to shock damage than a solid state CompactFlash card. The second thing is, the Transcend 2.2GB is simply a re-badged Microstor 2.2GB Microdrive. This Microdrive has one of the worst reputations of any CF format media that I've seen. Especially if it's the 1st version, which will actually cause cameras like the Canon 10D/300D to error out and lock up, forcing you to power cycle the camera to clear it. Do a Google search for "Microstor 2.2gb" and behold the horror. :) If I was going to spend ~$180, I'd probably get a couple 512MB CompactFlash cards or 1 good 1GB card. If you're going to shoot Large Fine JPegs with the Nikon, you can probably get around 200 images on a 512MB card. If you shoot with uncompressed TIFF (the 5400 doesn't do RAW) you are looking at a whole lot less. Bloated TIFF format will let you get about 32 images on a 512MB card. -=>Donald
