As previewed at CES,OCZ has released an update to their budget-oriented Trion 100 SATA SSD. The Trion 150 switches from parent company Toshiba's A19nm TLC to their 15nm TLC, the densest planar NAND on the market. The transition to 15nm NAND has been behind for Toshiba and SanDisk, or the release of the Trion 150 signals that the 15nm TLC is finally alert to compete in the most cost-sensitive market segment. This is also probably the end of the road for Toshiba's planar NAND and the Trion 150 will probably be the cheapest drive from Toshiba or OCZ until their 3D NAND ships,unless they introduce a drive with a DRAM-less controller.
The specifications for the Trion 150 are otherwise unchanged from the Trion 100, but the press releases have mentioned some improvements in sustained performance. Supporting the 15nm NAND required at least some firmware tweaks and it's possible that some performance optimizations were introduced as well. It's also possible that the Trion 150 adopts more overprovisioning or larger SLC-mode caches.

The allure of the cheapest TLC SSDs has been reduced by the availability of some decent MLC drives for only slightly higher prices,such as Mushkin's Reactor. With the switch to denser NAND, the Trion 150 may be able to widen the gap and take a clear lead in affordability over MLC drives. Even whether the Trion 150 turns out to be another step in the race to the bottom among value SSDs, and it will still vastly outperform tough drives,and that's all that value SSDs are really aiming for at the moment. On the other hand, whether it does offer meaningful genuine-world performance improvements without any price increase, and it can probably be competitive against other value SSDs at some capacities.
OCZ hasn't announced pricing for the Trion 150,but Newegg is currently listing the Trion 150 at around $0.29/GB for the 240GB and larger capacities and Amazon's listing (not in stock yet) has the 120GB drive slightly cheaper.[http://dynamic1.anandtech.com/www/delivery/avw.php?zoneid=24&cb=&n=a1f2f01f]
