They have 4 GB to 64 GB capacities and three-year warranties

CompactFlash cards are an order of magnitude faster than SDHC cards and their variations, but they also have a distinctive format that limits their potential uses.

Still, they can be great assets to those cameras and camcorders that support this technology. The latest cards from Green House show that clearly.

There are five of them, with capacities of 4 GB, 8 GB, 16 GB, 32 GB, and 64 GB, respectively. And as it tends to be the case of all NAND Flash-based storage devices, transfer speeds vary accordingly.

The 4 GB card is, of course, the slowest, managing a read speed of 107 MB/s and a write speed of 11 MB/s. That's better than the minimum expected from Class 10 SDHC 64 GB cards, if you want a comparison.

The 8 GB Green House CFast 2.0 GH-CFS-NMB memory card has read and write speeds of 132 MB/s and 21 MB/s.

Things get even faster for the 16 GB one: 256 MB/s read, 39 MB/s write. Finally, the 64 GB card has a read speed of 312 MB/s and a write speed of 153 MB/s, almost twice what the one immediately below can accomplish.

All newcomers have a JMIcron controller ECC (error correcting code) and bad block management. A three-year warranty accompanies each of them, but no price is known as of yet.
