Thanks.
Very helpful again.
At first I thought that the constraint might be the Pine's 2.0 USB controller but if the random write performance from pine sd card to usb stick went down while the random read performance from Pine sd card to USB stick went up it doesn't seem that the Pine's 2.0 USB controller is what is limiting usb random write performance..
Using an Intergral 64GB USB 3.0:

More data is always better!
So for random writes it looks like your Intergral 64GB USB 3.0 is faster (14,658 kBytes/sec) than the Pine64 SD card (11,300 kBytes/sec).
Xalius, how do these results stack up against the Pine64 card and my Integral 64GB USB 3.0? For this test I used my Kingston Datatraveler Ultimate USB 3.0.

4) Integral 64GB USB 3.0 Jamesread90 14,658 kB/sec
5) Pine64 SD card xalius (11,373 kBytes/sec).
This ignores cost of each option.
Jamesread 90 what is the difference between your results in #2 and #4?

Hello
The choice of sdcard is rather important, sd cards suffer from a symptom called 'Wear Level', this where cards that are constantly being written over and over again such as dashcams or video camera cards, suffer premature failure due to data blocks within the memory stack being corrupted and not accepting any more data. The blocks are tagged in the VTOC (Volume Table of Contents) and the 32gb sdcard is no longer 32gb, The Samsung line of SDcards (extreme usage) though a little more expensive seem to hold up the best when benchmarked, it is very important that the card is specified for high read/write (sometimes you may see a card specified for video for example) and the phrase the phrase Extreme Usage' should be displayed in the item description, this information is well known to the SD card manufacturers and is just now making its way into general parlance.
