Transcend CompactFlash 400x 64 GB

A line of flash drives with a speed rating of 400x will suit owners of computers whose motherboard does not support the USB 3.0 interface. Accordingly, the maximum speed of reading and writing data on such PCs is limited to 30 Mb / s.

Speed

The actual performance of the memory card (60 Mb/s read and 30 Mb/s write) fully corresponds to the claimed values. Reading data is even a little faster — at speeds up to 67 Mb / s. Only a few instances that write files twice as slowly cause complaints from the owners of memory cards. Such devices are subject to replacement, since the manufacturer gives a five-year warranty on his offspring.

Potential

The flash drive is best revealed on penultimate SLR cameras, for example, Canon EOS 5D Mark III or Nikon D3s. 64 GB of memory allows you to accommodate 1500-1800 RAW files in maximum quality. For shooting high-definition video, Transcend's lineup has faster models: Transcend CompactFlash 800x 64 Gb or Transcend CompactFlash 1000x 64 GB.

Reliability

Numerous owners of a memory card characterize it as a reliable and trouble-free assistant, with whom you do not have to worry about the safety of the footage.

Reference. The speed rating of CompactFlash memory cards is indicated as a multiplier (for example, 1000x), where the value of 150 kb / s acts as an x. It was chosen for a reason — this is the minimum playback speed of a CD (the main storage medium in the early days of CF cards). Deciphering the speed indicators of the drive, knowing its index, will not be difficult. So, the model with the 600x prefix provides a data processing speed of 90 Mb / s, and with the 1000x index — 150 Mb / s.
