Try to to a benchmark with CrystalDiskMark or AS-SSD instead.
Those tools are more widely known.
Your figures are very low.
ZTC only has data of the 64G model on their website. On eBay and Amazon sellers advertise the 128G model to have read speed up to 550MB/sec – write speed up to 490MB/sec.
So better speed than your figures could be expected.
I tried Adata and MyDigitalSSD SuperBoot, both do around 300 MB/Sec write and around 400 MB/sec read. The SuperBoot is the fastest of the two but in real life not noticeable.
The ZTC gets good reviews on Amazon… and the reviews that show screendumps of CrystalDiskMark show good performance.
So, try CrystalDiskMark (free) and compare your results with those within the reviews on Amazon.
