SDXC and its mythical promise of providing 2TB of storage along with 300MBps transfers. Truth be told, that was at CES two years ago, and here we are 24 months later oohing and ahhing over 128GB. Ah, the pains of (sluggish) progress. Griping aside, we're fairly sure that professional video junkies will be more than elated to hear of Lexar Media's two newest cards. The 64GB and 128GB Class 10 SDXC cards "offer minimum guaranteed speeds of 133x (20MB per second)," and ship with a limited lifetime warranty. If all goes well, they'll be splashing down into retailers later this quarter, with price tags set for $399.99 (64GB) and $699.99 (128GB). Just to put that into perspective, SanDisk shipped a Class 4 (15MB/sec) 64GB SDXC card right around this time last year for $350, and it's now going for half of that on the street. Yeah, ouch.
