Samsung 830 256GB
Results: Crystal Disk Mark
Crystal Disk Mark is a lightweight benchmark that has two parameters: Sequential and Random read/write, to evaluate the performance of a drive. Crystal Disk Mark’s default test uses random data and the writes in particular can be very punishing on Sandforce drives, and even moreso on asynchronous NAND equipped drives. First up is the default setting of a random data test.
Let’s take a look at the speeds.
This result is very good. As you can see the Samsung 830 goes through CDM’s random data like its not even there. Take a look at the 406MB/s write speed; this is the fastest we have recorded for any SATA III drive in this category. Now check out the 4K results; still good but not quite as spectacular. Keep in mind, the 4K test is somewhat indicative of how well the drive can perform with what is typically found in daily use on an operating system drive.
Let’s see what the same test looks like using compressible data.
More of the same, as this drive does not care if the data is Random or RAW. This is very good to see.
