Folder Transfer test

We put each card through a folder transfer test. For this

we changed our standard parameter and we created a

folder containing 2GB (Instead of 1GB) data which included

videos, photographs, Mp3 files, setup files and word files. We

transferred the folder from the computer to the SD card and

vice versa and recorded the time taken to do so. Transferring

the folder from card to computer was recorded as the read

time, and from computer to card as the write time. The read

time for the Kingston was clocked at 27.31 seconds. SanDisk

was slower than the Kingston clocking 27.48 seconds to read

the files. When it came to the write time, Kingston recorded

37.85 seconds while SanDisk had almost the same write time

of 37.17 seconds. However the overall performance of both the

cards in the folder read-write test was neck and neck.

In-Camera test

We took the SD cards and ran it through our next test, the

in-camera test. The camera used for the test was a standard

Nikon D850 with fixed a shutter speed of 1/125s, aperture 7.

and ISO 100. The camera was set to continuous shutter (High

burst mode) and photographs were taken in JPEG. Photos were

shot for 30 seconds and the total shots were divided by 30 to

get frames per second comparison of the two cards. Kingston

had a score of 6.63 fps, along with SanDisk which was a close

second at 6.3 fps. Here as well, the cards performed almost

exactly the same.

Each of the cards fought extremely hard in the tests,

proving once again the fierce but healthy competition between

the manufacturers.

Conclusion

SanDisk Extreme PRO SDXC UHS- I 256GB

Card

SanDisk came second in the Crystal

Disk Mark test with a read speed of 90.

MB/s, and a write speed of 71.25 MB/s.

In the folder transfer test the SanDisk

had a slightly faster write speed by 0.

seconds, clocking 37.17 seconds, and in

the read speed department it clocked at

27.48 seconds. The in-camera test score amounted to 6.3 fps.

Priced at `13590* (MRP), it is comparatively a pocket friendly

high-performance card, thus taking the second place in the

shootout.

Kingston SDXC UHS- I 256GB Card

The Kingston consistently performed

toe to toe almost in every test. It had a very

good score in the Crystal Disk Mark test,

clocking a read speed of 90.34 Mb/s, and

a write speed of 76.31 Mb/s, and also in the

in-camera performance test with a higher

score of 6.63 fps. In the folder transfer test it

was close to its competitor with a read time

of 27.31 seconds and a write time of 37.

seconds. While it marginally beats the SanDisk

in most of the tests, it is also quite pocket friendly

coming in at `12,999* (MRP).
