The Drive

SSD Front
SSD Back

We received our drive in just an anti-static bag without any retail packaging. It conforms to the dimensions set forth by the 2.5" form factor. It is made out of metal to improve its durability and is only 7 mm thick, which ensures it will fit into modern notebooks.

SSD Interface Connector

The Seagate BarraCuda SSD uses the SATA 6 Gbps interface. It is compatible with any older SATA standard, but will, in such a case, work at reduced performance.

SSD Flash Chips

The TLC flash chips are made by Intel, using their 3D TLC technology, probably with 96 layers.
