When we reviewed OCZ's first SSD built with triple-level-cell (or TLC) flash, the Trion 100, we found its performance a bit wanting. OCZ went to work behind the scenes to improve the performance of its budget SSD, and last month, the company announced a follow-up to the Trion 100. This latest drive uses Toshiba's newer 15-nm TLC NAND and brings 50% more Trions to the table. Say hello to the Trion 150.
Just like the Trion 100 before it, the Trion 150 comes in 120GB, 240GB, 480GB, and 960GB flavors. OCZ claims that this drive delivers "increased real-world performance" over its predecessor, but it doesn't claim higher specs for the newcomer. The official performance numbers are all the same as the Trion 100's.

We've got the Trion 150 480GB on hand for our review. We originally tested the Trion 100 480GB drive, as well, so it'll be easy to compare the new drive's performance figures to the old one's. Let's open it up and see what's changed apart from the stylish new sticker.
As we already knew, what's changed is the NAND. The Trion 100 used Toshiba's A19 TLC flash, but its successor leverages Toshiba's 15-nm TLC. The controller inside the Trion 150 hasn't changed at all—it's the same Toshiba TC58 we saw in the Trion 100. We'll have to credit the majority of any performance increases we see to the new NAND. Maybe the process shrink will at least partially make up for the fact that we're still looking at planar TLC.
The non-technical specs haven't changed either. All versions of the Trion 150 come with three years of OCZ's ShieldPlus rapid-exchange warranty coverage. And just like the Trion 100 480GB, the Trion 150 480GB is rated for 120TB of total bytes written, spread out across 110GB per day. Since this is an entry-level drive, it doesn't come with fancy extras like encryption acceleration in the controller.
The 480GB drive we're looking at sells for $129.99 on Newegg right now. The 120GB version will set buyers back $45.99, while the 240GB version rings in at $69.99 and the 960GB drive sells for $269.99. Those numbers are all solidly in the entry-level SSD pricing tier.
Now that we've seen the basics of the Trion 150, it's time to see what Toshiba's 15-nm TLC can do.
