We’ve taken a look at a couple of portable SSDs here at the labs and all of those have been USB3. Now the question I pose to most of these makers of external SSDs is that if the speed is sufficient, you can boot up a system via USB3. Then again you’d be stuck a USB3 drive and that defeats the purpose of having a super-fast boot drive if you’re always on your main system and not moving around. That being said, there are times when you might want to switch machines and all your data are in one place. These are typically the scenarios where’d you’d want the versatility of a portable drive and Apacer has exactly with the Apacer AS720 dual-interface SSD. With both a USB3.1 and SATAIII interface, this device offers fast storage and versatility in one package.

Test Setup

Processor: Intel Core i7 6700K
Memory: Kingston HyperX Savage DDR4-3000
Storage: Transcend MTS800 512GB
PSU: Thermaltake Toughpower Grand 1000w

All results are from SATAIII testing. Tests done after saturation write/erase cycle test.

Potential Performance

ATTO Disk Benchmark benchmarks a drive’s read and write speeds with increasing file sizes and graphs them.


Potential Write Performance

For potential write testing, HD Tune was used to measure the drive’s write performance. Again, we focus on the average results for real-world relevance.


Crystal DiskMark

Crystal Disk Mark is storage benchmarking software was developed by “hiyohiyo” of Japan, and is available for free. Crystal Disk Mark measures sequential, and random read/write speeds of storage devices.


Real-world Test: File Transfer

We’ve taken our compression test files, a collection of images, documents and other files ranging from 1KB to 50MB amounting to 3,343 files for 3GB and a single, large 12GB file. We’re posting the raw transfer results for your reference. Test data is copied off a PCI-express SSD.

So having tested the drive, out of the box we got around 540MB read and 450MB write on both interfaces, sometimes USB3.1 edges out SATA on write speed on average but that depends on your work load. In our testing, it did shy below 500MB/s reads and lower on the write speeds but that was after a good workout.  Overall speeds are satisfactory though via USB3 but in SATA it could’ve been better.

With a price tag of $116 for 240GB this hovers outside the range of value-oriented drives. It does make up for it with its convenience of being a dual-interface product. Apacer did a good job creating a product for people looking for a convenient way to use both interfaces. While there’s a perfect scenario for this, there’s not a lot of folks that would need but for those who do this is a perfect product.
