Hi, I have a 2Tb WD HDD acting as 2nd internal drive in my PC. I also have several offline HDD's that I use for data backup/storage. They all have a MBR partition. Will converting them to GPT decrease the chance of data corruption? I read that GPT is better at keeping data integrity over MBR.

Use GPT If:
  1. HD is greater than 2.2.TB
  2. You use the drive as Windows OS installed with UEFI style partition
  3. You plan to create more than 4 primary partitions

No speed differences. No need to go GPT on a drive under 2.2 TB.

If you need to store large data, recommend to convert MBR to GPT. MBR disks support up to 2TB per partition, and GPT disk supports up to 256TB per partition. MBR supports up to 4 primary partitions, and GPT supports up to 128 primary partitions .
