Manufacturer description

The ADATA HD720 2TB external hard drive is built for people who need their backup to survive the trip, not just the desk. ADATA rates the HD720 to IPX8, meaning it can sit submerged in 2 meters of water for 120 minutes, and to IP6X for complete dust protection. Shock resistance goes beyond the MIL-STD-810G 516.6 standard, with ADATA testing drops from 1.8 meters. The 2TB capacity gives you room for full-system images, RAW photo libraries, or years of project archives on a single portable drive. The blue silicone shell uses a carbon fiber-like pattern that adds grip when your hands are wet or…

SpecPicks Verdict

SpecPicks scored ADATA HD720 2TB USB 3.0 Waterproof/Dustproof/Shock-Resistant… using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. ADATA's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Is the ADATA HD720 actually waterproof, or just splash resistant?

It carries a full IPX8 rating, which ADATA defines here as submersion in 2 meters of water for 120 minutes. That is well past splash resistance, though you should dry the USB port thoroughly before reconnecting.

Will the HD720 survive being dropped?

ADATA drop-tests the HD720 from 1.8 meters, which it states exceeds the MIL-STD-810G 516.6 shock standard. The silicone shell with its carbon fiber-like pattern absorbs the impact.

Does it work with a Mac?

Yes. ADATA lists Mac OS X 10.6 or later, alongside Windows XP through 8.1 and Linux Kernel 2.6 or later. Reformatting to APFS or HFS+ is typical for Time Machine use.

Can I use it on an older computer without USB 3.0?

Yes, the drive is backward compatible with USB 2.0, though transfer speeds will drop to that port's limits. USB 3.0 is recommended for moving large 2TB backups.

How much data does 2TB actually hold?

2TB comfortably covers full system images, large RAW photo libraries, or multi-year project archives. Usable space after formatting is slightly lower, as it is on every drive.
