Perhaps this is typical, or normal, by my SDXC card slot has the standard SanDisk 128GB MicroSD card inside it, and whilst using HD Tune Pro, Im getting 30-40MB/sec read/write times, which are mainly 'burst' rates, as the rate drops every few seconds and then spikes anywhere between 30-40MB, which needless to say makes for error-prone writing/program downloading/streaming/etc. To put that in perspective, the internal SSD 256GB SP3 drive gets anywhere between 200-300MB/second read/write times. With that being said, the drive is basically unusable, for anything other than archival storage. Questions: 1) Is this normal/typical of this drive? 2) Why is there such a difference between the two memories? Why can't they make SD card slot thats just as quick as the SSD? 3) Is there anything I can do to improve data transfer times? Thank you!
