OCZ Arc 100 240GB SSD review

1. Features, specifications

OCZ launched the Barefoot 3 platform and the Vector SSDs in late 2012. Since then, the Barefoot 3 was met in the company's Vertex 450 SSD series, which was a more mainstream version of the Vector and came backed by a three-year warranty.

OCZ is back in the mainstream SSD game with the ARC 100. The SSD uses Toshiba's latest 64Gbit A19nm MLC NAND and the Barefoot 3 M10 controller. The smaller process node NAND means that performance takes a slight hit from the newer NAND. But endurance is still rated at the same 20GB per day for three years, which is more than enough for typical client workloads.

The ARC 100 does not support low power states (slumber and DevSleep), so idle power consumption remains high compared to the competition. In addition, ARC 100 only supports ATA passwords and no TCG Opal encryption.

Today we take a look at the 240GB (256GiB of raw NAND) version of the OCZ ARC SSD, which (256GiB of raw NAND) has sixteen dual-die packages with each die being 8GB (64Gb) in capacity. Here are the specs for all the OCZ Arc series:
