External SSD Transcend ESD350C: now twice as fast

External hard disk on NAND 3D TLC flash memory chips, Packed in a lightweight and durable aluminum case, protected by a removable silicone case.

What does it look like?

The device is the size of a credit card (this comparison does not apply to thickness). It has a USB type-C connector and a tiny led indicator. There is nothing else on the case – no buttons, no display, just a protruding nameplate on one side. The case is worn tightly and can be removed with difficulty, however, there is absolutely no need to remove it for the user, except out of curiosity. In addition to the shock-proof function, the case hides 4 screws that hold the halves of the case together. The case is protected from unauthorized disassembly by holographic stickers-seals on both sides, damage to which entails the loss of a three-year warranty. Weighs “naked” SSD a little more than 70 grams, in the case-almost 90.

What is included?

In addition to the drive itself in the case, the box has two more cables: USB A-USB C and USB C-USB C, both half a meter long.

How convenient is it?

The size and weight of the drive are comfortable, it is convenient to hold in your hand, it easily fits in your pocket or purse, but does not make you look for yourself for a long time. The indicator is quite bright, but when viewed at an angle becomes almost invisible due to the fact that the led is located deep in the housing.

How fast is it?

The manufacturer claims a maximum read speed of 1050 MB/s, and a write speed of 950 MB / s. This is twice as high as the previous ESD230C/240C/250C models. Of course, these are values for ideal conditions. the actual speed may differ greatly depending on which device the drive is connected to and what speed of ports and data carrier this device has.

What about compatibility?

By default (from the factory), the disk is formatted in exFAT, but this instance arrived for testing with the FAT32 file system and, accordingly, was easily read by all the devices to which I connected it, including the TV and DVD player. But in this file system, the maximum file size is limited to four gigabytes, so, for example, a full-length movie in high resolution and with a decent bitrate will not be recorded on this medium. If there is such a need, it means that you need to change the file system to exFAT or NTFS, but then it is not a fact that you can successfully connect it to something other than a Windows PC. Some smartphones work with exFAT, but not all. My Oukitel U23 on the MTK chipset refused to read SSD c exFAT.

Are there any additional features?

Transcend Elite proprietary SOFTWARE offers functions for backup of randomly selected files and folders from your computer to an SSD (manually or on a schedule, with or without encryption), recovery from backups, and data synchronization. Syncing with dropbox and Google Drive cloud storage is possible.

How is it working?

With computers running Windows 7 and Windows 10, the drive worked without any comments, was detected and connected quickly, and did not heat up much. In addition to tests, I used it to store photos in RAW format and work with them on my home and office computers. Despite the lack of USB 3 support in both computers, images were loaded and drawn quickly, and it was comfortable to work with.

The “smartphone + SSD” bundle easily coped with viewing videos in Full HD resolution with a bitrate of 27 MB / s and a frame rate of 50 frames per minute. The only caveat – after connecting the disk, you need to wait 2-3 minutes each time until the system checks it, and only then you can work with files on the SSD.


Transcend ESD350C is a fast, convenient and cute external SSD. The price is about one and a half times more expensive than the previous models ESD230C/240C (with half the speed of reading and writing), which looks quite justified.
