SSD units are real pain to benchmark. This is due to the fact that there are no dedicated speed tests available for the drives. HDD tests tend to use test methods that do not work the same on the SSD units thus making comparison between the results almost impossible. This time we selected to use some of the proven products from more seasoned SSD testers - Atto Disk Benchmark, Everest and CrystalDisk.
As a comparison drive we will be using Seagate's ST3750330AS 750 Gigabyte, 7200 RPM SATA unit.
As the graph clearly shows the Patriot Warp v2 SSD loves to transfer chunks from 64 kilobytes and up. 170.2 megabytes per second on the read and 96.8 MB/s on the write are in par with what the manufacturer states (175/100).
Seagate on the same SATA controller reads 101 megabytes per second and writes 96.3 megabytes. In this particular benchmark the MLC SSD drive is clearly faster when it comes to read speeds and is equally fast when writing to the disk. Let us see if the trend continues with the next benchmark.
First an overlook. When looking at the figures related to reading data from the disks the SSD unit clearly outperforms the regular, platter based HDD. On the other hand the SSD stresses the CPU a bit more but not in an alarming fashion.Random read
When the random read is presented in a graph form, one can see the difference in technology bit better. Reading speeds on HDD fluctuates more than with the Patriot's SSD unit. Peaks are rougly 50 megabytes apart with both drives but SSD is more consistent with its performance. Also the average MB/s on SSD is 122.2 compared to 82.1 on the Seagate's HDD ( 48.8 % faster ).Access times
As there are no arms to move the delays are also a lot smaller. No contest here.
Seagate on the left and the Patriot Warp v2 SSD on the right. Numbers inside the screens are situated so that the reading results are on the left and write test results are on the right.
Warp v2 once again gets the same results than what the manufacturer have presented. Larger chunks yeld better results although I'm bit puzzled on the relation between the read/write speeds on the HDD. This said, the performance trend that the first Atto tests started continues to all of the benchmarks that we ran.
