Leave the past behind

Forget your old external hard drive. The SE730H’s 500MB/s read and write speeds combine with USB 3.1 Gen 2 10Gbps delivery to usher a new era of fast. Four to five times faster than hard drives, the SE730H can transfer a 5GB full HD movie in 16 seconds and an average AAA game in under a minute!

Reversible USB-C: it’s always the right way

Thankfully the SE730H uses a USB-C (Type C) connector, which is reversible. There’s no annoying up or down like with traditional USB. No guessing, just plugging in the first time. Every time.
*USB-C to USB-C cable included.

IP68 dust and water proof plus military-grade shock proof

We make sure the SE730H passes strict IEC IP68 standards. That means complete dust resistance and normal operation even after an hour in 1.5m of water. So don’t worry and get mobile – your data is safe. Beyond resisting dust and spills, the SE730H also meets MIL-STD-810G 516.6 impact resistance so it can survive accidental drops and shocks with ease.
*Dust and water proof capabilities apply when USB port cover is firmly closed.

3D NAND Flash boosts durability and performance

Like most ADATA SSDs, the SE730H made the move to 3D NAND. The new technology is more durable and power efficient than 2D NAND, with the 3D TLC NAND in the SE730H having a 25% longer lifespan compared to previous generation SE730 drives.

Stylish, ultra-light portability

Totally different from heavy and bulky external hard drives and even some external SSDs, the SE730H weighs just 33g. You can barely feel it, plus it’s so compact it easily fits in pockets and bags. Of course, it’s also very elegant, using a metallic design with choice of distinct colors. While compact, it does stand out .

Share and enjoy across platforms

Plug n play with Windows, Mac OS, and Android means you can move content between devices without limitations. Whether for work or enjoyment, the SE730H empowers you with simple connectivity and the convenience of USB-C.
