Frequently Asked Questions
What is hardware RAID 5 and why does it matter?
Hardware RAID 5 distributes data across multiple drives with parity protection, allowing the system to recover from a single drive failure without data loss. Unlike software RAID, the ER104UT+B's dedicated RAID processor handles all redundancy calculations independently, delivering faster performance and lower CPU overhead on your host system.
Can I use the EliteRAID ER104UT+B with older USB 2.0 systems?
Yes. The ER104UT+B features full USB 2.0 backward compatibility, allowing seamless integration with legacy systems. While performance will be limited to USB 2.0 speeds (~35-40MB/s), the unit will function normally, making it a future-proof investment that works with your current infrastructure.
How does the 1U rackmount design benefit data center environments?
The compact 1U form factor maximizes rack density, allowing you to deploy multiple storage units in minimal physical space. This is essential for data centers managing large-scale backup and archival operations while maintaining efficient cooling and cable management.
What RAID configuration should I choose for my backup needs?
For maximum data protection with good performance, RAID 5 is ideal—it protects against single drive failure while maintaining 75% usable capacity. RAID 1 offers simpler mirroring, RAID 10 combines both for higher redundancy, and JBOD allows independent drive access. Choose based on your balance of protection, capacity, and performance requirements.
