FAQs

Q: What does 4Kn mean?
A: 4Kn is a native 4096-byte sector size that can improve efficiency. It requires 4Kn support from the controller, RAID stack, and operating system.

Q: Can I mix 4Kn with 512e drives?
A: Avoid mixing sector formats within the same RAID set or virtual drive; use matching formats for best compatibility.

Q: Is the drive self-encrypting?
A: No. This is a non-SED model.

Q: Will it operate on a 6G SAS backplane?
A: Yes, it can negotiate down to 6G SAS if the backplane/controller supports the drive and 4Kn format.
