recommended micro sd card ?

[xrez]

Ok so i tested both cards and here are the results:

Kingston 16GB class 10 UHS1
Sequential Read (Q= 32,T= 1) : 72.947 MB/s
Sequential Write (Q= 32,T= 1) : 10.459 MB/s
Random Read 4KiB (Q= 32,T= 1) : 6.633 MB/s [ 1619.4 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 0.421 MB/s [ 102.8 IOPS]
Sequential Read (T= 1) : 71.308 MB/s
Sequential Write (T= 1) : 10.066 MB/s
Random Read 4KiB (Q= 1,T= 1) : 6.341 MB/s [ 1548.1 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 0.406 MB/s [ 99.1 IOPS]

Transcend 8gb Class 4

Sequential Read (Q= 32,T= 1) : 22.491 MB/s
Sequential Write (Q= 32,T= 1) : 6.475 MB/s
Random Read 4KiB (Q= 32,T= 1) : 5.560 MB/s [ 1357.4 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 1.876 MB/s [ 458.0 IOPS]
Sequential Read (T= 1) : 23.072 MB/s
Sequential Write (T= 1) : 5.871 MB/s
Random Read 4KiB (Q= 1,T= 1) : 5.493 MB/s [ 1341.1 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 1.882 MB/s [ 459.5 IOPS]

Both used Test : 50 MiB [D: 0.0% (0.0/4815.0 MiB)] (x5) [Interval=5 sec] via crystaldiskmark x64

So looking at it the transcend only beats the kingston in speed at the random writing parts, but i find the speed in the pine64 from those 2 cards really different as the transcend loads things up faster and doest hang as much. Is the random write speed really that differentiating?
