Performance Result
Alright, let’s find out how does Transcend ESD350C perform in these synthetic benchmarks. By the way, your system needs to have USB 3.1 Gen 2 interface else you will not get the best out of it. Of course, host hardware and storage capacity might also affect the performance. Based on specs, ESD350C can get up to 1,050 MB/s for reading and 950 MB/s for writing.

Hmm… Look like my host system is pulling ESD350C from performing at its best. Getting 860 MB/s sequential reading and 815 MB/s writing in CrystalDiskMark.

ATTO Benchmark results are better with 886 MB/s read and 840 MB/s write.

AS SSD Benchmark performance is slower. You can refer IOPS and access time scores here now.

Final test with Anvil’s Storage Utilities…

Transcend ESD350C is indeed smaller and compact when compared to normal 2.5″ portable HDD. In addition, it runs cooler too thanks to aluminum alloy casing for greater heat dissipation. In addition, its built-in dynamic thermal throttling mechanism and enhanced heat management technology further ensure that this PCIe-based ESD350C delivers superior endurance and stability.

500 MB/s constant writing speed throughout all the file transfer thanks to fast SSD controller and plenty of cache buffer. Rest assures that it won’t slow you down when copying those large games ISO or movie files. By the way, 65 GB file is being used here. P/S – Look like it’s time for me to upgrade the test system PC.
