Roundup: CompactFlash Cards For Professionals

Silicon Power Professional Compact Flash Card (32 GB)

Our 32 GB test sample provides ample capacity for all sorts of applications, but the performance doesn’t meet expectations. We measured write throughput of 29.5 to 35.3 MB/s; read performance was 40-44.1 MB/s, which is better. We didn’t find information on the type of flash memory used by Silicon Power, but looking at the poor I/O performance results we are fairly sure that it has to be MLC flash.

However, the device is certainly a good deal if you get it much cheaper than other products, or if you get this 32 GB device for the cost of other 16 GB CF cards, assuming performance is not your primary requirement.
