Summarizing the results, OCZ's Trion 150 480GB SSD offered great performance in read tests although it could be faster in the write part, and delivers an overall good value, considering its retail price.
The drive gave some very high and competitive sequential read speeds, performed very well with 4K ~ 2MB transfer files (read) and almost perfectly in 4K random reads, although it was slowing down a bit when in 4K reads with higher than QD32 and QD64. Anvil Storage granted a great score to the Trion drive in the read tests, mainly with 0-fill data.
In the write part, sequential tests positioned the Trion SSD among the top performers in the category. On the other hand, the drive's performance with small 4K file transfers could be improved, especially in 4K random write 64 thread tasks. On the bright side, write transfers of larger MB files returned very good results.
We should also mention that the drive's performance in both the PC Mark 7 and PC Mark 8 benchmarks was lower than we expected, as the drive seems to be latency-sensitive with random workloads.
Street price for the Trion 150 480GB drive is currently $139.99 over Amazon.com. At this price, we have to do with approximately $0.28 per gigabyte for the new drive - a nice price if you are considering a SATA SSD for a system upgrade.
