Controller
Model of the controller installed in the SSD.
The controller is a control circuit, which, in fact, ensures the exchange of information between the memory cells and the computer to which the drive is connected. The capabilities of a particular SSD module (in particular, read and write speed) largely depend on this particular scheme. Knowing the controller model, you can find detailed data on it and evaluate the capabilities of the drive. For simple everyday use, this information is usually not needed, but for professionals and enthusiasts (modders, overclockers) it can come in handy.
Nowadays, high-end controllers are produced mainly under such brands:
InnoGrit,
Maxio,
Phison,
Realtek,
Silicon Motion,
Samsung.
TRIM
Module support for the
TRIM command.
A feature of the operation of SSD modules is that when deleting data in the normal mode (without using TRIM), changes are made only to the “table of contents” of the drive: certain cells are marked as empty and ready for new information to be written. However, the old information is not deleted from them, and when writing new data, you actually have to overwrite it — this significantly slows down the speed of work. The TRIM command is designed to correct the situation: when it arrives, the drive controller checks if the cells marked as empty are empty and cleans them if necessary.
Of course, this function must be supported not only by the drive, but also by the system, however, the ability to work with TRIM is built into most popular modern operating systems.
M.2 cooling
The presence of a heatsink in an M.2 form factor drive (see above).
The heatsink is usually a metal plate attached to the drive board. It improves heat dissipation, which is especially important under high loads associated with large volumes of information. M.2 drives with a heatsink are mainly intended for high-performance systems, in particular gaming ones.
We also note that M.2 radiators are found as equipment on motherboards, so if the drive itself does not have this function, you can choose
a “motherboard” with a radiator for it.
