What is a RAID controller and why do I need one?

A RAID controller is a hardware card that manages multiple drives in a RAID array. It boosts performance, adds redundancy against drive failure, and helps servers handle larger storage workloads efficiently.

What RAID levels do refurbished RAID controllers support?

Most cards support RAID 0, 1, 5, and 10, with higher-end models adding RAID 6, 50, and 60. Choose the level that best balances performance, redundancy, and capacity for your workload.

Are refurbished RAID controller cards reliable?

Yes. At EuroPC, every controller is professionally refurbished, fully tested, and supplied with a warranty. You get enterprise functionality at a lower cost while extending your server’s lifecycle.

Which servers are compatible with your RAID controllers?

We stock controllers for Dell PowerEdge, HP ProLiant, Lenovo ThinkSystem, and more. Popular models include Dell PERC H730/H740P, HP Smart Array P440, and LSI MegaRAID 9361. We guarantee compatibility when purchased through EuroPC.

What’s the difference between hardware RAID and software RAID?

Hardware RAID uses a dedicated controller that offloads work from the CPU and enables features like battery-backed cache. Software RAID is OS-managed, uses system resources, and is better suited to smaller or non-critical setups.

Do RAID controllers come with cache and battery backup?

Many enterprise controllers include onboard cache (e.g., 512 MB, 1 GB, 2 GB+) and optional battery or flash-backed write cache (BBU/FBWC) to accelerate writes and protect data during power loss. Check model specs for details.

What warranty do refurbished RAID controllers come with?

All RAID controllers from EuroPC include a minimum 12-month warranty covering hardware defects. Extended cover may be available depending on the model.
