SanDisk Super Speed USB 3.1 solid State Flash disk review: The speed is comparable to that of SSD

By  Matty Logan 2020-02-03 1824 25

For SanDisk, I believe you are no stranger, as the global leader in flash storage solutions, it has been committed to solving the dilemma of portable and performance of mobile storage devices, which also gave birth to many excellent products. It is in this environment that SanDisk Super Speed USB 3.1solid-state flash drive was born. So, as the most high-end flash drive under SanDisk, how does it actually perform? Come and experience it with me today!

Appearance and specification

First of all, let's take a look at its outer packing.

SanDisk Super Speed USB 3.1 solid state flash drive packaging continues SanDisk classic black and red color matching, the box marked the main parameters of the product, you can see, I have this is the 128GB version, but there is also a 256GB version, the capacity can top a SSD.

In addition, another highlight of the USB disk is shown on the package: the read speed of 420M/s and the write speed of 380M/s.

The various matters needing attention are explained in detail on the back of the package. Seeing here, it can be said that the outer packing of SanDisk alone is so precise that I can't help but want to take a look at the package.

Open the package, the contents are very simple: U disk body and a card, the card is actually a SanDisk Rescue PRO (flash drive repair tool) activation code card, can be used to activate SanDisk Rescue Pro software, can reply to accidentally lost or deleted files in the U disk to ensure data security.

At first sight, I was attracted by its exquisite appearance, and the gray tone of the gun looked low-key and of quality. Hold it in your hand, unexpectedly light, can not feel the weight at all. In addition, the aluminum shell also brings a good feel, but also can effectively protect the internal structure of the flash drive.

The SanDisk LOGO, printed with SanDisk on the front interface is marked with the USB 3.1logo on the other side.

The Extreme Pro, printed on the back of the USB drive is SanDisk's flagship series, Super Speed, with a capacity of 128GB.

The USB interface uses a telescopic design, and there is a button in the middle of the U disk, so you can easily push the USB interface out by pushing it up. When pushing out the interface, the sense of resistance is relatively moderate.

The actual reading and writing speed test

After seeing Meimei's makeup photos, let's see what level of performance it is and whether it is worthy of the title of "Supreme Super Speed". The main purpose of this evaluation is to test the speed and compatibility of SanDisk Super Speed USB 3.1 solid state flash drive on Windows 10 and macOS 10.13.

In terms of capacity, the actual capacity is 119GB, because there are some differences between the manufacturer's capacity algorithm and the system algorithm. The manufacturer calculates the capacity according to 1000KB=1MB, while the system calculates capacity according to 1024KB=1MB. From the previous online disassembly diagram, the chip is Xiangshuo Technology's ASMedia ASM1153E SATA3 (6Gbps) To USB3.1 Gen1 (5Gbps) transfer chip.

In terms of read and write speed, we use CrystalDiskMark, a well-known open source hard disk read and write speed test software, and ATTO Disk Benchmark and AS SSD Benchmark test software from ATTO, a supplier of high-performance network storage products, to test SanDisk Super Speed USB 3.1 solid state flash drives. Among them, CrystalDiskMark uses the storage performance testing software DiskSpd developed by the Microsoft cloud server team as the bottom layer, and its results are authoritative and have a certain reference value.

TEST 1 :ATTO Disk Benchmark 256M

From our measured data, we can see that the read speed does not reach the officially claimed 420M/s read speed, the actual read speed is about 370MB/s, which is close to the officially declared write speed 380M/s.

TEST 2 :AS SSD Benchmark

Next, we use AS SSD Benchmark to test the read and write speed, the actual performance is that the write speed is about 370m per second, and the read speed is about 350m per second. Although it is still lower than the official standard data, it already exists very quickly in U disk, which is much faster than other U disk of the same price.

TEST 3 :Disk Speed Test

Next, we also used DiskSpeedTest, a hard disk speed test tool from Mac App Store, to test the performance of SanDisk Super Speed USB 3.1solid-state flash drive in macOS. The actual performance is not much different from the previous data on window, and the measured write speed is 335.1MB, and the read speed is 381.5MB/s.

Actual experience sharing:

The experience of using such a high-speed flash drive to transfer super-large video files, games, or video clips is also great. For example, if most people use an ordinary flash drive to transfer material, it may take 5 minutes. If you are unlucky, you may have to wait for the flash drive here after work. But if you replace it with a SanDisk Super Speed USB 3.1 solid-state flash drive, it will take only 30 seconds to complete the transfer, unplug the USB drive and clock in directly to go home.


SanDisk Super Super Speed USB 3.1solid state flash drive, as the most high-end flash drive under SanDisk, is also the fastest USB flash drive on the market, with a reading and writing speed of 370,370 and 350MB/s, killing most USB drives on the market in seconds. In addition, it also has gun gray ultra-high appearance, SanDisk solid workmanship and other excellent features. If you want to choose a flash drive at the same price, there is no doubt that SanDisk Super Speed USB 3.1 solid state flash drive will be a good choice.
