What is RAID?
RAID (Redundant Array of Inexpensive Disks/Redundant Array of Independent Disks) exists as a way to combine multiple storage hard disks into a single array. Which discussed in our previous blogs. (Click here to read the blog). So, why does we need more time to recovery the data? Let EHDR share some point with you.
If a NAS with RAID systems, all of the HDDs’ sequence need to remain the same at all time. These HDDs are not supposed to mix up. Imagine, if you have 16 bays HDD without a proper sequence. You will not be able to access the data or unable to boot up. It will need longer time for our recovery specialist to pick and puzzle the correct HDD’s sequence.
Begin Sector of RAID
Is also referred to stripe size, it is written to each of the storage media in a RAID array. This block size is not adjusted by user. Recovery specialist needs to identify the size in order to calculate the begin sector and the end sector of RAID.
Identify RAID Type
There are various famous RAID structures used amount people such as RAID 0, RAID 1 and RAID 5. But there are also devices that use more than 1 RAID structure or come with unique RAID level such as 1E, 5E, 5 EE and etc. You won’t be able to access the data without identifying the exact RAID structure that used by the faulty devices.
In RAID, there are many ways to organize data. For RAID 5, It comes with 4 different layouts such as Left Synchronous, Right Synchronous, Left Asynchronous and Right Asynchronous which is crucial for data recovery.
There are many users use this RAID system. It helps us to backup our data easily, but it tenses to failed because of human error. As it makes our life easier, it will also make us headache if it failed and it will need longer time frames for recovery. So, make sure you do the proper configuration or contact EHDR. Our EHDR Data Recovery Specialist will help you to configure your system properly and get a peace of mind in using your storage device.
