Introduction

OCZ is one of the earliest adopters of SSD technology, and their products have always been at the forefront of technology. A few years back, the company was acquired by Toshiba, which gave OCZ the ability to be a first-class customer to Toshiba's flash chips and other NAND-related technology.

The OCZ Trion 150 is the sucessor to the Trion 100, which was OCZ's first drive with TLC flash. Unlike MLC, which most SSDs use, TLC stores three bits per cell, which increases capacity and drives down cost, though at reduced performance, which became apparent when we reviewed the Trion 100. The Trion 150 we are reviewing today is built on 15 nm flash, instead of the 19 nm flash the Trion 100 uses.

The Trion 150 comes in capacities of 120 GB, 240 GB, 480 GB, and 960 GB.

Packaging

The Drive

The drive conforms to the dimensions set forth by the 2.5" form factor. It is made of metal to improve its durability and is only 7 mm thick, which makes it compatible with Intel's Ultrabook specification.


Like most recent SSDs, the OCZ Trion 150 uses the SATA 6 Gbps interface. It is compatible with any older SATA standard, but will, in such a case, work at reduced performance.


You will find the SSD controller and 16 flash chips on the PCB. A DRAM chip is also present; it provides the SSD controller with RAM.


The Toshiba controller is the same as on the previous Trion 100 model.


The sixteen TLC flash chips, produced by Toshiba, are built on a 15 nanometer process.
