Crystal Disk Mark 3.0 is next in the ring. Generally, higher capacity drives tend to perform a little better in these tests. The ability of a controller and flash memory to deliver high IOPS also results in better rated speeds. The Gigabyte UD PRO 240GB is rated at up to 70,000 IOPS read and 40,000 IOPS write. Looking at the sequential read and write results, the Gigabyte UD PRO 256GB was quite competitive with others in its class, defeating all of the Kingston UV400 and UV500 drives, while mostly being faster than Crucial's MX drives. In the 512K section, the UD PRO ranked fourth fastest in reads, while nearer the bottom of the pack for writes. This is understandable, considering its smaller capacity compared to other drives, though it was slower than the Toshiba OCZ TL100 and Crucial BX300 at similar capacities. For the 4K results, the UD PRO's read performance was surprisingly better than all but one, while the write performance was middle-of-the-pack. Finally, in the 4K QD32 test, its read speeds were near the upper half of the drives compared, while the write speeds were dead last. From all of these tests, you can see the UD PRO's read speeds are quite competitive, while the write speeds are relatively underwhelming. I will let you make your own comparisons in our massive list of SSDs in the graphs above.
