I thought M600 kicked the bucket, didn't think it'll last that long. Liteon uses Toshiba or Micron or Sk Hynix SSD ICs so you should be good for 10-15 years.@Vasudev my boot disk is a simple 1TB Micron M600 which I got for INR 11 379 on ebay. My backup SSD is a strange 960GB Liteon ect-960n9s rated 1 disk write a day for 3 years, MTBF 2.5 million hours and power off data retention guaranteed for 1 year. They're not the fastest in benchmarks but they are fast enough.
