Benchmarking the SSD using SiSoft Sandra (Sequential)
In our first test, we use SiSoft Sandra to run a HDD/SSD test on it for read and write performance. We will first test it by connecting it directly to our desktop PC using the SATA300 interface. Subsequently, we put the device in the USB enclosure and retest the read and write with USB.
Read and Write test using SATA only
Read performance is pretty decent for the value SSD. In the benchmark test, it is able to achieve a 216MB/s with a 250us for random access time. As for write performance, it can do a 177MB/s which is pretty decent. From the chart, the red line shows an almost straight line with little bumps. That shows that the average read is quite consistent throughout the 64GB SSD. In fact, it is very close to what the two Intel SSD is able to deliver. The two others from G.SKill and Corsair has lots of ups and downs, that indicates the inconsistent nature of the SSD during the read process.
Compared to the Intel X25-M 80GB, this device seems to have a faster write and slower read performance. The Intel X25-M scored 80.6MB/s for write and 238MB/s for Read. (ref
Write Performance with SATA interface
From the chart, the write performance is at 177MB/s which is way ahead of the most of the Reference drives used in SiSoft benchmark. The Samsung 256GB (green coloured) is still way ahead at 211MBp/s in write.
As usual, USB will always be the bottleneck for the SATA3Gbps connected SSD. As we can see from the chart, it’s performance for read is 30.7MB/s and a write speed of 32.29MB/s
