Android tablet never saw the disk, despite dancing with a tambourine, Paragon NTFS and other similar programs. Apparently, the tablet does not provide sufficient USB power. Attached to the USB port of a wifi router, not very good, but still a local cloud solution. Recording to the cloud 5Mb / s, reading 7Mb / s, the bottleneck is the USB2.0 port of the router. When connected via USB3.0 to a laptop, the speeds are as follows: Sequential Read : 100.689 MB/s Sequential Write : 103.871 MB/s Random Read 512KB : 33.384 MB/s Random Write 512KB : 4520221 MB/s Random Read 4KB (QD=1) : 0.378 MB/s [ 92.3 IOPS] Random Write 4KB (QD=1) : 1.022 MB/s [ 249.4 IOPS] Random Read 4KB (QD=32) : 0.528 MB/s [ 128.9 IOPS] Random Write 4KB (QD=32) : 1.077 MB/s [ 263.0 IOPS]
