Waterproof and quickly

I have 2 SH 93 from Adata, the two yellow USB devices are quite capable of surviving in the urban jungle.
Unfortunately, quite slow with 20 Mbytes / sec.
The two blue HD 710 are very fast. The water resistance I've been through
Sample tested in the dishwasher, the drives have survived.
4 stars because the silicone shell was not quite solid at the delivery,
some superglue but this has changed.
The next best class of USB Disk survival can be found probably only in
I / O safe, the high price. Fortunately ranging HD710 for me, yet I do not need a Titan block to have my data secure
