Frequently Asked Questions

RAID Basics

What is RAID?

RAID (Redundant Array of Independent Disks) combines multiple drives into one logical volume for performance, redundancy, or both. Common levels: RAID 0 (striped, no redundancy), RAID 1 (mirrored), RAID 5 (striped with parity), RAID 6 (double parity), RAID 10 (mirrored and striped).

RAID 5 vs. RAID 6 – which is safer?

RAID 6 survives two drive failures; RAID 5 survives one. RAID 6 is safer but slower and costs more capacity. See our RAID 5 and RAID 6 pages.

What is a RAID rebuild?

After a drive failure, the array recalculates the missing data from the remaining drives and parity. If a second drive fails or has hidden errors during the rebuild, the array crashes – and a bad rebuild can corrupt everything.

Recovery Process

How long does RAID data recovery take?

Typically 3-15 days, depending on complexity and data volume. Emergency service runs 24-48 hours.

Remote or in-lab – which do I need?

Logical issues (RAID config, deleted data, crashed volumes) can often be handled remotely. Physically damaged drives need the lab.

Do I need to send the RAID controller?

No – we rebuild arrays virtually and don’t need your controller or original hardware.

Pricing & Guarantees

How much does data recovery cost?

Most RAID cases run $1,000-$2,500 per disk, depending on the case. The evaluation is free.

What does “no data, no fee” mean?

If we can’t recover your data, you pay nothing – not for evaluation, not for work.

Do you ship a free kit?

Yes – we’ll arrange a shipping kit and instructions for your case; or use our Work Order Form.

Device-Specific

Do you recover NAS devices?
Do you recover virtual machines?

Yes – VMware, Hyper-V, VMDK, VHDX, VMFS. See VM recovery.

Emergency

How fast is emergency recovery?

24-48 hours with a priority lab slot. Call 844-223-7243 and say it’s an emergency.

Do you work 24/7?

Our engineers answer the phone around the clock – including weekends and holidays.
