Product review: ADATA USA SE730 250GB USB 3.1 Gen 2 Type-C Waterproof Portable Solid State Drive

This external SSD drive is very compact: 3" long x 1.75" wide  x 3/8"thick.

 The highest read bandwidth was 457 MB/sec using 1000 MByte samples. The highest write bandwidth was 316 MB/second, using 100 MByte samples. The write bandwidth curves were choppy, while the typical write speed was 316 MBytes/second Gnome disk measured the peak speed as 405 MBytes/second.

The drive uses a USB-C connector. It comes with a very short USB-A to USB-C cable. The cable is adequate for a laptop but not a desktop system. For desktop systems you will need to buy a long cable otherwise the drive will likely to dangle in the air.

All tests were run on an 32G Intel Skylake iCore7 system running Fedora 24 Linux.  You will notice that I ran the tests for different file sizes. At small file sizes the overhead of the operating system has a large impact, as file sizes grow larger the SSD approaches it's maximum transfer rates.
