OCZ Trion 100 (240GB, 480GB & 960GB) SSD Review: Bringing Toshiba to the Retail

For full details of how we conduct our Iometer tests, please refer to this article.
Fortunately sequential read performance is better than random, although for some reason the performance decreases as the capacity goes up. It seems like the controller may have trouble keeping up with the increasing number of LBAs to track, or frankly it could be just poor optimization too because the Neutron XT has no similar performance issues despite the similar underlying architecture. Another explanation could be increased latency from higher density NAND packages as there is some performance penalty due to longer wiring, although Samsung doesn't have any performance issues with its high density packages.
Unlike the performance, power consumption does go up with capacity, making the higher capacities less efficient.
The reason for poor performance lies in bad scaling because it takes a queue depth of 16 until the 480GB and 960GB models reach their peak performance.
Sequential Write Performance
Sequential write performance, on the other hand, is as poor as random write performance. I'm again surprised that the higher capacities present only marginal increase, whereas in write performance the additional NAND should help to distribute writes to a larger number of die for increased performance.
Power is again pretty high, though, especially when considering the performance against other drives.

Published endurance ratings != actual endurance!!!Published endurance ratings are only used for two reasons:
1) To keep write heavy enterprize users away
2) For warranty purposes (A published endurance rating gives a hard cutoff for the end of warranty period, besides the time period running out)
ACTUAL endurance of the NAND is usually WAY higher, especially with the Samsung 850 series drives.

It looks like these drives have had their endurance validated according to the JEDEC JESD219A client workload specification, which means it's actually a meaningful value rather than one arbitrarily set by the manufacturer to keep heavy users away.jann5s - Thursday, July 9, 2015 - link
I'm really really really curious to some data retention measurements. I would appreciate it greatly if AT would throw some MLC and TLC SSD's in the vault for half a year and then report back with an awesome review!Ken_g6 - Thursday, July 9, 2015 - link
Looks like the Trion is a drive to bypass. Maybe they'd do better with a drive called the "Succeedon".camelNotation - Thursday, July 9, 2015 - link

Samsung's 850 line looks poised to have as much staying power as the 830s (luckily I skipped the buggy 840 EVO since I wasn't looking for more capacity at the time)... Looking forward to some BF or Amazon's 20th deals on that 1TB 850 EVO! (tho I probably should've just bought it when it hit $340 not long ago) Is Samsung releasing a new series early next year or are they all about PCI-E/M2 moving forward?The_Assimilator - Thursday, July 9, 2015 - link
2.5" SSDs aren't going away anytime soon, so I'm sure we'll see Samsung 860 series SSDs in the future. How soon is the question, because it seems there's not much that can be done to speed up drives without having them bottlenecked by SATA3 and AHCI.Gigaplex - Thursday, July 9, 2015 - link
The advances for the 860 series are likely to focus on density rather than performance upgrades. However, there is still a lot of room for improvement in random IO performance.Byte - Thursday, July 9, 2015 - link
Samsung already announced 2TB 850 Evo and Pros, the prices look pretty good also. Its gonna be hard to top the 850 series!http://www.bit-tech.net/news/hardware/2015/07/07/s...

You guys act like the 840 EVO was the worst drive in the world. I've had 0 problems with mine in the year that i've owned it and couldn't be happier.
