A-Data HD710 Pro AHD710P-4TU31-CBK 4 TB

bat tank

If Batman suddenly came to the electronics store with his Batcredit card, he would come back with a nice box from A-Data, in which there would be an external HDD DashDrive Durable. And there are 2 reasons for this. The first is a solid appearance, which is somewhat reminiscent of that tank from The Dark Knight. The bristling black (there are also other colours) box seems to have been born to deal with any adversity and meets them with a smirk.

Shock-resistant body is not afraid to fall and drown

The second reason is a serious layer of armor. Serious, even by the standards of shock-resistant hard drives. The protective casing consists of three parts: a durable silicone outer bumper, inside of which is hidden a shock-absorbing frame that absorbs shock and vibration, and under them the last line of protection in the form of a durable plastic case that tenaciously holds the hard drive. As a result, the case was tested according to the military standard MIL-STD-810 and received an IPX7 certificate, that is, it is not afraid of drops from a metre height (A Data says that the drive withstood 26 drops from a height of 122 cm) and withstands a short immersion in water for a metre depth. The main thing is not to forget to close the ports with rubber plugs. Well, in general, it’s not worth specially subjecting the miniature mechanics of a hard drive to such torture.

130MB/s sequential read

Judging by the Crystaldiskmark benchmark data, a 4-terabyte HDD from Seagate (formerly Toshiba) is hidden inside the case with a speed of 5400 rpm and a 128 MB cache. In synthetic benchmarks, the drive averages 130MB/s sequential read and 123.7MB/s sequential write. There is nothing unusual here, these are close to the maximum figures for a third-generation USB HDD. Speaking of USB. Like many protected "outsiders" in the case there is a special mount for the cable. On the one hand, this is convenient, since it is always at hand, on the other hand, the cable is short and it is not very convenient to connect it to a computer that is somewhere under the table.
