ADATA SD700 Review

ADATA SD700 Review

Last Updated on by Daniel Lawrence

ADATA SD700 is a small, portable external SSD that should satisfy your desire to take games and movies anywhere, and share them across multiple devices.

ADATA SD700 provides a perfect backup solution for your media files in a pocket-size and fast device. External SSDs are extremely lightweight for nearly half a terabyte of storage and are faster and more efficient than HDDs. For a few days, I tested the SD700 and was impressed by its portability, ease of use, and performance.

Design: Tiny but tough

SD700 has a lightweight and compact design, unlike many other external hard drives that are housed in bulky frames. With its easy design and portability, it’s easy to understand why the manufacturer emphasizes its versatility as a media drive on the go. Small enough to fit in a jacket pocket, this 3×3-inch square weighs just 2.6 ounces and is barely noticeable.

Despite its size, this SDD is durable. There is a solid metal shell surrounding the entire body, which is protected by a layer of thick and durable rubber. Although the rubber casing gathers lint quite easily, it’s nothing new for this type of material.

In spite of its looks, the SD700 has the grades to prove its ruggedness. This device meets IEC IP68 standards, meaning it can withstand dust and submersion in nearly 5 feet of water for an hour. In addition, ADATA claims that the SD700 is military-grade protected. Due to its MIL-STD-810G 516.6 shockproof rating, this device can handle drops and bumps safely from 4 feet above the ground. Dropping the SD700 on hardwood and cement caused no scuffs, damage, or performance hiccups.

Performance: Fast and consistent

According to ADATA, the SD700 can handle a 5GB video file in just 26 seconds. According to the manufacturer, I was able to transfer 5.17GB of movie files in just 26.2 seconds.

Despite its small size, this device is incredibly durable.

Although this product is not marketed as a gaming drive, I downloaded NBA2K directly to the SSD to test it. The hefty 98GB file was installed in a little over an hour. This is about 40 minutes faster than the WD Black P10 and nearly one hour faster than the 512GB NVMe SSD storage on the Acer Predator Triton 500 gaming laptop. The drive took about 20 seconds to load, which is not lightning-fast but similar to other HDDs I tested.

When benchmarked with CrystalDiskMark, the SD700 reached read speeds of 421MB/s and write speeds of 429MB/s, which are consistent with manufacturer estimates of reading speeds up to 440MB/s and writing speeds up to 430MB/s. Writing speeds were 410MB/s and reading speeds were 416MB/s for the Black Magic Design Speed Test.

 Ports: Limited to USB 3.0

There is only one USB 3.0 interface on the SD700, so it isn’t compatible with macOS, Windows, or Android devices. An adapter can be purchased for use with newer MacBook Pro or Android devices with USB-C ports. It’s a bit of a letdown, though, that there is no USB-C support, especially since competing devices do support it.

Setup: Ready to go for the most part

This factory-formatted solid-state drive supports NTFS (New Technology File System) on Windows machines. You’ll need to perform the exFAT file formatting required by most external HDDs and SSDs if you have a MacBook. It only took seconds to format the drive to make it compatible with both Windows and macOS computers.

Key Features: 3D NAND performance

SSDs are known for being faster and quieter than HDDs, and for having greater stability. SD700 uses the latest 3D NAND triple-level cell technology to provide fast, consistent, and efficient performance. Despite its limitations, NAND technology has a typical lifespan of 100,000 read/write cycles. Unless you plan on doing a lot of demanding with this SSD, this may not be an issue for you. It’s hard to beat how quiet and cool this SSD performs if you need to store and access media files for personal use.

ADATA SD700 vs. Samsung T5

There are many similarities between the Samsung T5 (see on Amazon) and the ADATA SD700. These SSDs are both fast and dependable, and portable as well. The T5 is even smaller and lighter than the SD700 with a weight of only 1.79 ounces, a width of 2.91 inches, and a height of 2.26 inches. Additionally, it is .41 inches thinner than SD700, which is .54 inches thick.

Besides its size, the T5 offers more versatility thanks to its dual USB Type-C to C and USB Type-C to A compatibility-and similar USB 3.0 and 2.0 compatibility to the SD700. Transfer speed is another area where the T5 excels. The SD700 can read and write up to 440Mbps, but this card has a reading and writing speed of 540MB/s. The SD700 uses TLC flash storage, but the T5 uses MLC flash storage, which is known to be more durable than TLC flash storage.

The Samsung T5 can survive drops from as high as 6.5 feet above the ground, according to Samsung. But it does not have the thick silicone rubber to prevent knicks and absorb impact like the SD700 does-and it does not have the military toughness or waterproof grade to back that up.

Each drive will need to be formatted for macOS and password-protected. When it comes to dollars and cents, the SD700 offers a bit more storage at a less expensive price.

Pros Cons
Fast read/write speeds Rubber cover attracts lint easily
Compatible with macOS, Windows, and Android No USB-C compatibility
Military-grade shockproof A bit pricey


Its low profile, stable and fast transfer speeds, and surprising durability make the ADATA SD700 a popular SSD. Choosing the right external drive depends on how much storage you need and how long you plan to use it. If you wish to back up movies and photos at faster speeds and in a more reliable format than with an external hard drive, this is the ideal device.
