Kingston CompactFlash Ultimate 600x 64 GB

The spacious data storage from Kingston has a claimed read and write speed of up to 90 Mb/s.

Speed indicators

In fact, the data reading speed is even 25% higher than the claimed figures — according to the results of testing the memory card by the Kaddr.com resource, the real speed indicators reached a value of 112 Mb / s. Recording is traditionally slower (about 58 Mb / s). These figures are confirmed by other authoritative sources. When using the "native" Kingston FCR-HS4 card reader, the write speed rises above the claimed figures and is almost 100 Mb / s.

Testing

In real shooting conditions, the memory card installed in the Canon EOS 1D X camera was able to record a series of 19 frames in RAW + JPEG format (378 MB) in 15 seconds. By simple mathematical calculations, we managed to find out that the average data recording speed is at around 25 Mb / s. In RAW format, 35 frames with a total weight of 637 MB fit on the flash drive, which were written to the buffer for 22.5 s — the final recording speed was 28 MB / s.

Videos

The memory card also allows you to record video files. But it should be remembered that the FAT-32 file system, which comes out of the box, limits the maximum size of one file to four gigabytes. Therefore, if you decide to write videos with a high bitrate, you must format the drive in another format (for example, exFAT).

Uninterrupted work

When idle, the memory card automatically enters standby mode, thus reducing power consumption. The flash drive works in tandem with all top cameras that support the CF format. However some owners of Nikon D800 and Canon EOS 7D cameras still note compatibility problems with individual copies. The manufacturer guarantees a 5-year uninterrupted operation of its product.
