Introduction

As users' demand for storage of phones increased, the storage of many phones has reached 1TB. However, it may not meet the needs of users who like to take photos and videos. So, a flash driver becomes a good choice. If you do need one, you should consider the compatibility issues.

ChargerLAB will test the compatibility of the flash driver and the mobile phone in shooting mode.

Test Equipment

ChargerLAB will use the iPhone 15 Pro, Huawei Mate 60, iPhone 14 Pro Max, and Samsung Galaxy S23 Ultra for the test.

The device tested this time is a 1TB solid-state flash driver and a USB-A to Lightning adapter.

The Disk Speed Test on macOS shows that the read speed was 916.5MB/s, and the write speed was about 841.2MB/s, reaching the 10Gbps transmission specification.

Then, let me show you the port transmission specifications of the four phones. 

The USB-C port of the iPhone 15 Pro is USB 3 (10Gbps).

As for the Huawei Mate 60, it is slightly slower which is USB 3.1 Gen1 (5Gbps).

The Lightning port of the iPhone 14 Pro Max is the slowest, which is USB 2.0 (480Mbps).

And the USB-C port of the Samsung Galaxy S23 Ultra supports USB 3.2 Gen1 (5Gbps) transmission capabilities.

Test

After turning on the "Apple ProRes" function on the iPhone 15 Pro. In the "Video" mode, the "ProRes" icon will be displayed in the upper left corner. The icon supports switching HDR/SDR/Log encoding formats. And the maximum recording time for internal storage and external storage is located at the top of the viewfinder. The photos taken will be stored first in the external device and then in the internal space.

After connecting to the Huawei Mate 60, the name and capacity of the external storage can be seen in [File Management].  There are no compatibility issues.

The taken photos can only be stored in the internal storage first and then transferred to the flash driver.

Connect the extra flash driver to the Samsung Galaxy S23 Ultra. The name and capacity of the external storage can be seen in [File Management], and there are also no compatibility issues.

The photos taken can only be stored in the internal space first, the same as the Huawei Mate 60.

Next, connect the flash driver to the Lightning adapter.

Connecting to the iPhone 14 Pro Max, the name of the external storage can be viewed in [Files], and there are no compatibility issues.

The functions of the flash driver are the same on the iPhone 14 Pro Max as on the iPhone 15 Pro.

Summary of ChargerLAB

The flash driver can deal with insufficient storage of the phone by storing phone files.

It can achieve more functions on the iPhone than the other two phones in the test. But older iPhones need an adapter to connect to the USB-C flash driver. So, the iPhone 15 series has the best compatibility with mobile flash drivers.
