The ADATA SE730 is an external mini-SSD with USB 3.1 interface.
Conclusion
The external SSD drive SE730 from ADATA is 36 grams and only 74 millimeters one of the most compact storage you can carry with you. The SE730 is available in the colors gold and red. But that is not the special thing. The golden jewelery box is certified according to the militarily standard IP68. It is protected against dust, dirt and water. Even a water bath of up to 60 minutes and a depth of 1.5 meters is said to be faultless. Your data should be protected from the weather.
However, your fingernails are less secure. The plastic cover, which covers the USB 3.1 Type C connector, fits properly - a strong thumb nail is an advantage.
In the test lab we determine proper values. The promised 500 Mbyte / s from the advertising brochure while reading and writing are not achieved - but so far, however, no single mobile SSD over USB, which has been tested in our company. Sequentially, the SE730 reads 240 and writes to 297 Mbyte / s.

The 4K transfer is 22 or 46 Mbyte / s, which is a good value. We calculate the peak value for writing with the ATTO benchmark with 8 MBytes of large files and a read rate of 320 MByte / s. The access time during reading is somewhat disappointing with 0.173 milliseconds, but very good 0.055 ms is achieved when writing. Also the heat development is relatively high, we measure an increase at full load of about 14 degrees Celsius above the ambient temperature.
The ADATA delivers good, standard performance data, but with heavy use it is a little more than hand warm. The great advantage of this mobile SSD is protection against dust and water.
