SanDisk Ultra Fit 3.1 128 GB (SDCZ430-128G-G46)

Ultra Fit

The American brand SanDisk, which is part of the WD conglomerate, is one of the most famous and recognizable manufacturers of flash drives and memory cards. The brand's products attract attention due to the combination of affordable price, high quality and interesting functionality. For example, the Ultra Fit 3.1 model is one of the most compact flash drives with a memory reserve of 128 GB — its dimensions are 30x14x5 mm and weighs only a couple of grams.

Invisible storage

The peculiarity of the flash drive is invisibility, this one will easily enter the port of the car radio or the third USB slot of the TV or laptop, without blocking access to neighboring ports, like some larger flash drives. When connected, it takes up less space than a tiny wireless mouse/receiver.

Perfect for medical content

Its speed indicators are within the normal range for low-cost models: according to official data, the buyer receives 130 MB / s when reading and it is not clear how much when writing. Measurements in CrystalDiskMark showed figures in the region of 109 MB / s during reading and 48 MB / s for writing. When copying files larger than 4 GB, a twofold drop in speed was observed, and in some cases the case became noticeably warm. The tiny plastic case is not designed for effective cooling. Considering speed drops, dimensions and heating, it seems to us that SanDisk Ultra Fit 3.1 is more likely to come down to the role of a compact media storage (movies on TV, music for the radio), and not an indispensable assistant who will scatter tens of gigabytes of small files every day.
