A-Data Durable SD700 ASD700-1TU31-CBK 1.02 TB
 | Outdated Product £124.99 1024 GB secure external SSD with high-speed USB 3.2 Gen1 interface, implemented using a USB 3.0 Micro-B connector and a USB Type-A PC cable. It is the top model in the A-Data Durable SD700 line, which includes drives with a capacity of 256, 512 and 1024 GB. Differs in moderate weight (75 g) and the small sizes of the strong plastic case with a rubber bumper. Withstands rain and splashes of water without problems, resistant to dust ingress — the level of protection complies with the MIL-STD-810G standard. The A-Data Durable SD700 ASD700-1TU31-CBK external SSD is based on the high-performance Silicon Motion SM2258 controller, equipped with a SATA-USB bridge and Micron's high-quality 3D NAND TLC memory. This configuration provides a decent read / write speed (430/440 MB / s), which is 2-3 tim...es faster than conventional mobile HDDs. The drive is great for copying or moving large/small documents, JPEG or RAW photos, FullHD/4K video content, and work project files. It can be used as a device to expand the permanent memory of a laptop or ultrabook. |

Protected data
The range of portable SSDs is still very limited, and if we talk about models with additional protection, then there is an empty niche at all, which the Taiwanese manufacturer A-Data is trying to fill.
The metal case is not afraid of shocks and diving under water
A-Data Durable SD700 is a secure SSD that looks like a black box sealed in several layers of protection in an airplane. They approached the protection of the drive in the most serious way: it complies with the IP68 standard (remains operational even after an hour of stay at a depth of one and a half metres), is not afraid of dust and has passed the MIL-STD-810G military certification in a test with mechanical shocks and shaking. We don’t know if you plan to throw it under the tank, but even if you constantly carry it in your bag during a crush on the subway, such protection will definitely not be superfluous.
Volume 1024 GB
Now let's look at the drive itself. It works on the basis of a modern type of 3D TLC NAND memory, the disk capacity is 1024 GB. When connected via USB 3.0 according to the passport, the drive provides approximately the same read and write speeds — 440 MB / s and 430 MB / s, respectively. This is neither more nor less than the average temperature in the ward. Moreover, the test results are identical to the passport indicators. It behaves especially well when working with numerous small files that ordinary flash drives suffer from. When writing very large files (for example, 80 GB), after a while the speed drops several times (the SLC buffer fills up). However, many drives based on TLC memory suffer from this.
Against the background of all that has been said, I did not like only the implementation of the rubber plug, which is needed to protect against water. The rubber base of the bumper does not have a clear fixation with the case and it can be accidentally touched when you take out the disc from the bag.
