OCZ Trion 150 480GB SSD Review

IOMeter Sequential Performance

Starting in April 2015 Legit Reviews brought back synthetic IOMeter v1.1.0 testing to our high-end Solid-State Drive reviews as we feel that the canned benchmarks no longer show enough of the performance picture nor do they expose many of the heat issues that we are starting to encounter on M.2 PCIe SSDs. We start out testing each drive with IOMeter, but first we prepare the drive. This is done by using Parted Magic to complete a full Secure Erase each and every drive. Next we use IOMeter to prefill the drive by performing the industry standard 128KB, aligned, sequential write workload across the entire drive for a period of 20 minutes. Once the drive is conditioned we run our saved sequential test profile that runs our 128KB test for two minutes without any idle time in between the tests. The queue depth is set to 32 as we feel with NVMe drives starting to come out that we need to increase our IO depth.

128kb MBps

The 128KB Sequential Read/Write test is done primarily to make sure the drives we are testing meet or surpass the manufacturer specifications for sequential Read/Write performance. The OCZ Trion 150 480GB drive topped out at 564 MB/s read and 325 MB/s write. The OCZ Trion 100 came in at 558 MB/s read and 164 MB/s write, so performance on the new Trion 150 series drive was better!

IOMeter 128kb IOPS

For those that like to know the IOPS results you are looking at around 4,300 IOPS for the sequential read and 2,479 IOPS on the sequential write.

IOMeter 128kb Response Times

Having high IOPs per second is generally considered good, but you also look at the latency when interpreting the results. Just because the IOPs are high it might not mean that the data is being delivered at a reasonable latency and this could cause for a poor user experience. The OCZ Trion 150 had the best read response time of the five drives tested, but the write response time was still nothing to write home about although it was much improved over the Trion 150 series.
