ADATA HD720 External Hard Disk (1TB) Review – Durability At Its Finest!


Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.

With Crystal Disk Mark, the sequential read speeds come in a little higher than our ATTO benchmark, at 116 MB/s and a max write speed of up to 113 MB/s.


AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected. Transfer speeds (MB/s) are seen in the left picture below and IOPS (Input / Output Operations Per Second) are on the right.

AS SSD is the power house of pretty much all benchmarks, so for this external hard disk drive to power through and provide pretty much similar results to what we have seen earlier, is pretty incredible to see. Read and writes speeds come in at 110 MB/s and 109 MB/s, respectively.

Another interesting feature of the AS SSD Benchmark is that it also can test  durations and speeds of copying various files, this is an important test for our digital media professionals who require top transfer speeds.

Anvil Storage Utilities is essentially an all-in-one tool for all of your SSD benchmarking needs. Anvil can be used for basic consumer testing, as well as endurance testing and threaded I/O read, write and mixed tests. It displays data regarding the SSD, and even about your system

Again, this drive is pretty boring in the sense that it provides the same results over and over again, which isn’t a bad thing! Read and write speeds come in a little higher than AS SSD, with both sequential read and write speeds at 111 MB/s.

Today we are looking at the latest, ultra durable external hard disk drive available from ADATA, the HD720. A few weeks ago we had the opportunity to look at the HD710A, which had a little different purpose, mainly for targeting the Mac market. The HD720 is your solution to water, dust and shock.

  1. I have achieved an ADATA HD 720-1T USB disk. I use it with an ASUS laptop as an external bootable disk for Linux (I have windows 8.1 installed on my SSD laptop drive). On the ADATA drive I have 3 different Linux distros installed. It work just fine (thanks to USB 3.0). Great product..
