Things to Consider

The biggest trade-off is speed: this is a mechanical HDD with sequential read/write speeds around 100-120 MB/s, far slower than any SSD. It is not suitable as a boot drive or for running demanding applications. The drive is also sensitive to physical shock, so handle with care during transport. While it is dustproof, it is not waterproof. Competitors like Seagate and Western Digital offer similar products at comparable prices, so compare warranty and features before buying. ## FAQ
