FAQs

Q: What is 512e and do I need special settings?
A: 512e uses 4K physical sectors with 512-byte emulation for compatibility. Most modern OS and RAID controllers support it natively; ensure firmware is up to date.

Q: Can I mix 512e and 512n drives?
A: Avoid mixing within the same RAID array. They can coexist on the same controller if used in separate arrays or pools.

Q: Does the Low Profile carrier support hot-plug?
A: Yes, Low Profile carriers support hot-plug in compatible LFF backplanes.

Q: Is 7,200 RPM suitable for databases?
A: It is suitable for capacity-focused workloads and sequential throughput. For write-intensive or low-latency databases, consider higher RPM or SSDs.

Q: How many drives can I add per controller?
A: Limits vary by controller model, backplane, and available bays. Consult your RAID controller specifications for maximum supported drives.
