Very good HDD, never disappointed with SanDisk.
I was looking for a good big HDD with good value for money, combining performance and security, and this one suited me perfectly. The rubber that surrounds the HDD prevents damage to the internal components when the mechanical parts are rotated, as they are subject to vibration. What's more, the L/E speeds are largely correct (90-100MB/s on average compared with a theoretical speed of 130MB/s). However, HDD formatting on Windows is rather complex if you're not familiar with it, as basic formatting is not available and full formatting is required via the Disk Manager. Finally, there may be some data read/write problems due to the potential overheating of the HDD when transferring large files (of the order of 100GB or more), which can be quite annoying in the long term.
