Lost my PC for two days, some data permanently. Can't stress enough the importance of backup.

The ADATA SX8600 Pro died less than two years in use. It's using Korean flash chip. To think these SSD all boasted 5 years "guarantee". Switched to NM790 that use YMTC chip. The upgrade from 2 TB to 4 TB only cost 30% more. Equivalent 4 TB SSD from Samsung is 50% more expensive than NM790.
