Since it's my first SSD hard drive, I was pleasantly surprised about the size. As an accessory, there was a SATA cable and a SATA power cable accessory for those whose power supply has no SATA power cable. (I'm sorry, I do not know how the connector is called). And to my delight, a 3.5-inch mounting frame was there.
The installation went smoothly, the speed is top and at the moment I can not complain about.
As it is, however, my first SSD hard drive, I can not make any comparison to others. For beginners this disk should, however, be satisfactory.
