Hello! I've just tested my 250GB Samsung 850 SSD using Magician software and CrystalDiskInfo, here are the results:

Samsung Magician: Drive Health -> 64.2 TB written - Good.
CrystalDiskInfo: Health Status -> Good 82%

  1. Should I be worried? I've read on some forums that this drive endurance is about 75TB written (about 10TB left). Is it time to buy another drive?
  2. I have a Asus Maximus Hero VII, should I buy an M.2 NVMe or just stick to a high end SATA like 860 Pro, 870 EVO, Crucial MX500?

  1. Should I be worried?
No.

Actual tested 'endurance' is often far far more than the warranty number.

As always, though...backups. Just in case.

Thanks for the answer! I was thinking about buying another SATA SSD just in case. Checking prices on Amazon, I've found:

  • Samsung 870 EVO 500GB/1TB $59.99/114.99
  • Samsung 860 EVO 500GB/1TB $79.99/134.99
That's weird, shouldn't the 870 cost more than the 860? Is there any difference between them? Which one should I get?

Either will work.
