Raid Data Recovery
Start recovering your RAID now (Exclusive support for all RAID levels 0, 1, 5, 6, 10, 50 or 60). Count on PhD Recovery’s team of experts!
Service in Emergency mode
Our department specializing in data recovery on servers can work 24×7.
We use the data confidentiality agreement (NDA – Non-Disclosure Agreement) as the most professional way to guarantee description, seriousness and loyalty
The process of RAID recovery is usually performed in order to recover information that for some reason has been lost or is currently inaccessible.
PhD Recovery works 24/7 on developing advanced technologies to enable data recovery on RAID systems of all levels, with any storage capacity, and whatever the operating system and its partition.
Even in extreme situations where you have two or more unstable disks, in cases of virtualized environments with compromised, corrupted or Ransomware-attacked virtual machines, we have the necessary expertise and the right technology to help you with your data recovery project.
PhD Recovery Specialist in RAID Recovery
Always believing it is possible is part of PhD Recovery’s success story. Count on our team of experts to successfully recover RAID and meet your organization’s data access needs.
In the emergency modality, the vast majority of the projects are executed and concluded within 48 hours, after the delivery of the data in our laboratory or even after a secure remote access to the environment is made available.
Through a customized NDA for your project, PhD Recovery guarantees total confidentiality during the entire data recovery process, or if you are more comfortable, we can use an NDA that your company has developed internally for this purpose.
PhD Recovery has a large and solid physical structure, a team of experts, highly qualified and with access to the best and most current technology. Our laboratory is fully equipped to serve your company in the best possible way.
We are available to work on your project 24/7/365, because we know the importance of data being available in an organization.
Allow PhD Recovery to show you that it is possible.

Recover RAID 0
RAID 0 is the most performant RAID level, because data recording is performed simultaneously between all disks in the volume. As for storage, the capacities of the disks are added together, thus contributing to a volume without loss of capacity.
- Minimum Number of Disks: 2
- Storage Loss Percentage: 0%.
- Disk Failure Tolerance: 0
- Performance | Reading: 2x
- Performance | Writing: 2x
- Usually the performance of a RAID 0 is quite optimized, both for reading and writing;
- There is no loss of capacity, because no disk is dedicated to data protection;
- The option to set up RAID 0 is present on all controllers, making it an easily accessible technology.
- Because it is not a fault-tolerant RAID, should one disk fail, unfortunately all data will be compromised.

RAID Recovery? 6 Golden Tips for RAID Data Prevention
Major server and storage manufacturers do not recommend shutting down a degraded environment, as this can increase the chances of further exacerbating the ongoing problem.
Although it is a concept still widely used in companies, it is not recommended to think that data stored on RAID replaces traditional data backup.
Make sure your server or storage is in an appropriate location that is air-conditioned and secure, so that natural wear and tear doesn’t prematurely damage the hardware associated with RAID.
Never perform a rebuild without first analyzing the logs generated by the RAID controller.
If any disk in the array presents some kind of problem and the orange led is on statically, program the replacement immediately.
Whenever possible have a hot spare disk in your environment, as this way an extra layer of security is implemented.

Why Choose PhD Recovery for RAID Recovery?
We have a team that specializes in RAID recovery at all levels, no problem is too big to stop us.
Count on the experience of someone who has been in the data recovery market for almost 14 years, with constant innovations in our technologies.
And with strategic partnerships with leading developers of data storage technologies, we can keep in line with RAID storage technology advances.
We know how important it is to have the data available as soon as possible, so we make the initial diagnosis within 24 working hours for free.
We will show that there is no scenario too difficult for recovery not to be attempted.
FAQ | Frequently Asked Questions
Unexpectedly, I can no longer access data from a RAID environment, what is the possible diagnosis for my case?
We have separated the five main causes that arrive in our laboratory:
- Improperly performed rebuild;
- Physical problems on several disks belonging to the array;
- Instability in the RAID controller of the server or storage;
- Physical damage to the server’s system board after a power failure;
- Unsuccessful attempt in the process of inserting new disks into an existing array.
Considering that the data stored on a server or storage is sensitive to the company, we have created a dedicated team 24/7/365 to meet demands like these, so the response time can be greatly optimized.
The first step is the advanced diagnosis, which can take between 4 to 6 hours. Once the advanced diagnosis is finished, and data recovery is possible, the average time to complete the project can take between 8h and 24h.
If you can’t ship the server or storage as a whole, we strongly recommend that you identify the disks and also pack them using anti-static plastic and then bubble wrap, to safely pack the devices involved in the data recovery process.
Depending on the nature of the problem related to the defective disks, yes, it is possible to recover data in a scenario like the one above, because we are technically able to clone the unstable disks and consequently remount the array in order to access the data contained in the logical volume.
SAS disks are usually more reliable compared to SATA disks, so for critical environments we recommend using SAS disks, which can be either 10K RPM or 15K RPM disks. The higher the RPM of the disk, the more performant the disk will be.
Yes, this concept is called Hot Spare disk and its function is to wait until an active disk fails, so that the backup disk can take its place, with the sole purpose of keeping the data security level at a reasonable level. It is recommended to replace the failed disk within 72 hours.
Currently we have three (3) statuses:
- Optimal: When all disks in the array are online;
- Degraded: When one of the disks in the array is offline;
- Offline: When two or more disks in the array are not being recognized.
Technically it is possible, but in practice it is hardly recommended, because all disks will be leveled by the lowest speed, so as not to compromise the synchronism of the data allocated in the RAID.
It will depend a lot on the behavior of the orange led, because if it is blinking, it means that the disk is trying to do a rebuild, if the led is on steadily, it means that the disk has some kind of defect, which requires an emergency replacement to avoid data loss.
In many cases it is possible to recover data from a RAID remotely, but it is necessary to first evaluate if your project is eligible for this modality, because there are several factors analyzed for this decision, such as type of problem in the disks, operating system and RAID level configuration.
