In case of any slow functioning, you have a kit which will always give you a notificatiosn and possible causes if not solutions to the problem. It can read and write at the same time check on the speed of the computer. This is the engine as well as the storage device of the computer. This is a benchmarking utility which helps in handling all the hard disk drives of the system. In the three threaded test run, we saw a drop off in performance from QDs 4 and 8.Having a hard disk drive is not complete, you also need to have a monitoring tool to keep the hard disk drive in check. When tested with CrystalDiskMark 7 the best we saw from the drive at QD1 was 47,774 IOPS (195MB/s). Samsung rate the SSD 980 at up 54,000 IOPS at QD1 with a single thread for random writes.
Using a single thread the drive produced a read figure of 16,293 IOPS (66.74MB/s) slightly below the official figure of 17,000 IOPS. We also used CrystalDiskMark 7 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads. Looking at the Peak Performance results we can confirm the official 4K random read figure with a test result of 502,214 IOPS with writes lower than the official maximum at 463,792 IOPS. The official 4K random read/write figures for the drive are up to 17,000 IOPS and 54,000 IOPS respectively at QD1 and up to 500,000 IOPS for reads and 480,000 IOPS for writes at QD32. The result screens for these two profiles not only display MB/s results but also IOPS and latency. We could confirm those figures with CrystalDiskMark 7 with a read performance figure of 3,569MB/s with writes a little shy of the maximum figure at 2,907MB/s.ĬrystalDiskMark 7 includes a couple of profiles that can be used for testing – Peak Performance and Real World. Samsung rate the 1TB SSD 980 as up to 3,500MB/s and 3,000 for Sequential read and writes respectively. In relation to the other drives around it, the SSD 980 shows better performance in CrystalDiskMark's 4K QD1 test as it sits in the top five of drives tested to date. Looking at the pair of result screens it appears that the Samsung controller doesn't appear to have any preference for the type of data it's being asked to handle. Testing the drive with CrystalDiskMark's 4K QD32 test produces a result that sees the drive sitting midway in our results chart. CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s.
