Performance Result
You should know a little bit of 480GB Transcend 820S M.2 SSD performance with above Transcend SSD Scope screenshots. Yes, it performs well thanks to high-quality flash chips and enhanced firmware algorithms. Perfect for notebook and other mobile computing devices with its shock and vibration-resistant. And DevSleep feature to prolong notebook battery life by intelligently shutting down SATA interface when not in use. Alright, let’s refer to below synthetic benchmark results to know more about Transcend 820S.

Transcend 820S performs align to its specs with sequential Q32T1 test with 559 MB/s read and 516 MB/s write on CrystalDiskMark. Slightly better writing performance on Intel X99 chipset that I am using here.

ATTO Disk Benchmark is getting about the same result for both read and write tests like CrystalDiskMark. No surprise here.

AS SSD Benchmark has slower reading speed compare to previous benchmarks which is expected. There are access time and iops results for your reference.

Anvil’s Storage Utilities provide the system information that been used for this benchmark. FYI, I am using Intel Core i7-5960X Processor Extreme Edition, Gigabyte GA-X99-Gaming G1 WIFI with 16GB of RAM and Windows 10 Pro 64-bit to run these tests.

Yes, Transcend 820S is loaded with fast controller and more than enough SSD caching write buffer. Therefore, you can enjoy constant and ultra fast writing speed throughout the whole file transferring process. Note – 20GB file is being used here.

PCMark 8 storage bandwidth test shows that Transcend 820S is almost 20X faster than 7200RPM hard drive. FYI, my 3TB HDD scores 11.20MB/s only while this M.2 SSD is getting 194 MB/s here. In addition, HDD takes around 3 hours+ to finish PCMark 8 test. And MTS820S takes around 1 hour+ only. Rest assures that Windows boot up, applications and games loading are much faster then.
