SanDisk Extreme IV
As we mentioned above, the Extreme IV series includes the fastest of all cards currently made by SanDisk. Their peak read and write speed is as high as 40MB/s according to SanDisk’s internal tests and they come in 2GB, 4GB and 8GB capacities. As opposed to the previous Extreme III series, there is no 16GB model in the new series. The manufacturer declares an operating temperature range of -25 to 85°C.
SanDisk USB Card-Reader
The SanDisk Extreme USB Card-Reader, equipped with a USB interface, was one of the two readers introduced along with the new flash card series. This reader is declared to ensure a write speed of 18MB/s with Compact Flash cards. This is a lower speed than the new card supports, yet is quite high for comfortable work with large-capacity cards. Besides Compact Flash, this reader supports Secure Digital and Memory Stick Pro Duo. It comes with a USB cord, a user manual and a CD with the RescuePro software for restoring deleted data on external disks.
