Should I Use a Non-Genuine Hard Drive to Replace a Failed One in My Dell Server?

As long as the replacement drive has the same interface (SAS for SAS, SATA for SATA), you should be fine. Just make sure it’s an enterprise-grade drive. It’ll work without any issues.

I’d definitely go for a genuine Dell drive. If it were a new setup, I’d probably choose WD Gold or Seagate drives instead, but for an existing RAID array, keeping the same model is a safer bet.

I've never encountered problems using non-Dell drives for replacement as long as they're enterprise-grade like WD Gold or Seagate Exos. Just steer clear of consumer-grade drives.

I’ve never used a 'genuine' drive in a Dell server myself. I’ve had success with various SAS and SATA drives from different vendors without significant problems. The only issues I faced were with some test drives that the server flagged as incompatible, which just led to some annoying alerts. Just be cautious about mixing different types in the same array; otherwise, picking up the same model from the manufacturer should work fine.

I've swapped out drives with non-genuine ones a few times in non-critical systems and generally didn't have any major issues. However, I do recall getting some strange disk-related alerts often. Since genuine drives are generally affordable and readily available, I'd recommend sticking to those to avoid unnecessary headaches.
