1.HGST 1TB is a mechanical hard disk, while Maubec S1 256G is a solid-state hard disk, which is faster and better, and more expensive at the same capacity. You are right to say that your original HGST 1TB mechanical hard disk is more than 1 times more expensive than Maubec S1 256G solid-state hard disk, but you should consider that this solid-state hard disk has only 256G capacity, while the mechanical hard disk has 1G capacity. If the price of the same capacity is compared, the general price of solid-state hard disk is about 3 times that of mechanical hard disk, and the speed is about 5 times faster, and the earthquake resistance is much better than that of mechanical hard disk. Your mechanical hard disk belongs to mechanical structure, so it may break down when it bumps slightly, but the solid state will not. Now the life of solid state is relatively long, and it will not produce any noise when running, so the solid state is of course better.
2. In addition, by the way, popular science:
HGST is Hitachi, which has been acquired by Western Digital. Later, its Chinese name was changed to Yuke, which belongs to a well-known mechanical hard disk company (of course, their family does not only produce hard disks), and it is basically the same as Western Digital's mechanical hard disks.
Maubec was founded in 1992. Its predecessor was a semiconductor company jointly organized by Huawei and 17 domestic provincial and municipal telecommunications administrations, and its headquarters was in Xi 'an. Later, Maubec sold it to Emerson. This solid-state brand retail market is rare, and the popularity of retail consumers is also low, and it is ok for daily use. In the future, it is recommended to buy well-known brands (Samsung, Toshiba, Western Digital, Kingston, Weigang, Yingruida, etc.), mainly because there are more after-sales outlets for big brands.
