Transcend ESD400 256GB External USB 3.0 SSD Review

Testing – USB 2.0

Our test system is setup as follows:

  • Gigabyte Z87X-OC
  • Intel i5-4670K
  • Sapphire R9-270X
  • 8GB (2x4GB) Kingston DDR3-2400
  • Crucial 256GB SSD (OS)
  • WD 500GB Black HDD (storage)
  • Thermaltake DPS-G 750W PSU

Here is the software we’ll be using in our testing:

  • Microsoft Windows 8 Pro 64-bit
  • ATTO Disk Benchmark
  • CrystalDiskMark 3.0.3
  • AS SSD
  • Anvil’s Storage Utilities 1.1.0
  • SiSoft Sanda
  • HDTune Pro 5.5

Below you’ll find the results of all of the benchmarks we ran with the ESD400 SSD connected to a USB 2.0 port.


Anvil’s Storage Utilities

“Anvil’s Storage Utilities is a powerful tool that was designed in order to provide you with a simple means of assessing the read and writer performance of your Solid State Drive or Hard Disk Drive. The benchmark tool helps you monitor and check the response time of your unit as well as view the system information collected using Windows Management Instrumentation (WMI).”


“Test the sequential or random read/write performance without using the cache. AS SSD Benchmark reads/writes a 1 GB file as well as randomly chosen 4K blocks. Additionally, it performs the tests using 1 or 64 threads and it determines the SSD’s access time.

Two extra benchmark tests examine the drive’s behavior when (1) copying a few big files, a lot of small files and a mixture of file sizes by using cached copy functions of your OS as well as (2) reading/writing data depending on the data’s compressibility.”

ATTO Disk Benchmark

“As the industry’s leading provider of high-performance storage & network connectivity products, ATTO has created a widely-accepted Disk Benchmark freeware utility to help measure storage system performance. As one of the top tools utilized in the industry, Disk Benchmark identifies performance in hard drives, solid state drives, RAID arrays as well as connections to storage. Top drive manufacturers, like Hitachi, build and test every drive using the ATTO Disk Benchmark”

With ATTO we get a rough baseline of the drive’s expected performance. We recorded a sequential read and write performance of 44.4 MB/s in ATTO. Read and write performance was about what we expected for USB 2.0

CrystalDiskMark 3.0

“CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows to measure sequential and random read/write speeds.”

CrystalDiskMark gives us a good view of single threaded sequential read performance.

HD Tune Pro 5.5

HD Tune Pro is a hard disk / SSD utility with many functions. It can be used to measure the drive’s performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more.”


SiSoft Sandra

“SiSoftware Sandra provides a robust package of diagnostic tools for testing your system and teasing out its problems–or potential headaches.”

You can see that when plugged into a USB 2.0 port the drive still performs quite well. Seeing how it’s an SSD rather than a mechanical drive that’s to be expected. Let’s see how it performs on USB 3.0 next.
