What is it?

The latest SSD external drive brimming with new technology. Most innovations start in a lab and trickle down through academic and professional applications until they are affordable enough for consumer products.

The features of the SV620H SSD from Adata have followed this life-cycle and been bundled together to create an impressive addition to the portable hard-drive market.

I won't bore you with a raft of technical details, but the succinct summary is that the SV620H boasts more transistors. This allows increased capacity and performance without being impeded by extra bulk and power consumption.

Good Points?

The most important job a hard drive performs is to read and write operations which the SV620H tested well against compared to standard SSD models.

The hardware was quiet during usage unlike the screeching you can experience with the vast majority of drives available. It was also remarkably cool to the touch even after playing a video stored on the device that lasted almost three hours in duration.

Adata have managed to buck the trend of companies releasing updated products at massively inflated prices.

Bad points?

The only negative is Adata's choice of the Micro-B USB 3.0 connectivity port, instead of utilizing the type-C connector which harnesses the flexibility and power of USB 3.1.

Best for ...

Those looking for reliability and great performance from their storage device.

Avoid if ...

You are in need of lighting fast transfer speeds as you'd be better off with a drive fitted with a thunderbolt connector.

Score: 8/10.
