A Closer Look
Both drives on test have the same 128 GB capacity but the components used to build each drive differ greatly. We will outline these differences below.
Kingston has chosen to use a metal casing for the V100 which should provide more than adequate protection for the components inside. It adds to the weight of the drive significantly, though, making it about the same weight as a 2.5” mechanical hard drive.
On the top side of the board we find the controller, which is unusually angled at 45 degrees to the memory chips. This is manufactured by Toshiba but is actually based on the JMicron JMF612 controller design with a few updates. It supports read and write speeds of up to 250 MB/s and 230 MB/s, respectively, and sports the model number JMF618.
The sixteen 8 GB Toshiba memory chips are distributed evenly between the two sides of the PCB. These are 32 nm MLC chips with the model number TH58NVG6D2FTA20. On the underside of the board we also find the Mira P3R12E4JIFF 64 MB cache chip.
Patriot has chosen to use a brushed aluminum enclosure for the Torqx 2, which gives it a robust feeling without adding much to the weight. In fact, the Patriot unit is about half the weight of the Kingston unit so is a better choice for notebook users.
Patriot uses the Phison PS3105-S5 controller for the Torqx 2, which has claimed read and write speeds of 270 MB/s and 230 MB/s, respectively. On the top side of the PCB, we also find the 128 MB DRAM cache chip. This is Hynix branded and has the model number H5MS1G22AFR.
Rather than use sixteen 8 GB memory chips like Kingston, Patriot has chosen to use eight 16 GB chips which are all located on the top side of the PCB. These are also Toshiba branded chips and have the model number TH58NVG7D2FLA89.
