How to upgrade storage systems and troubleshoot storage

A large number of pictures and video files so that my storage space seriously inadequate, how to do? Or buy a high-end desktop system. Of course, the system is the first to have a flexible deployment function, of course, the second is to save money. Pick and choose, I bought a motherboard that supports SATA raid and four 250G high speed SATA drives, 1TB space is used to store raw data.

The equipment has been bought, the following should be installed manually.

First, set up a system drive and a data drive, respectively. To ensure disk performance for large AV files, the remaining two drives are set to RAID 0. The data is then backed up to a 5TB NAS system and 2 200G USB2.0 extended drives. In order to install multiple operating systems and run operating system virtual software, I need large capacity systems and data drives.

The system is installed, the test runs normally, this is the storage structure that I need. Next, install the application, guide the data from the old system, everything goes well. The coveted fast storage subsystem and the Bleeding-edge CPU with enough RAM are all implemented.

Next, use the storage repair tool that came with the system board to process the write failure of the storage strip. This is not a lot of errors, because many of the data are backed up elsewhere. The beginning of a few days, all normal, but not long before the problem. Updates the raid drive, still repairs the storage volume with the tool, and everything is back to normal. But a few days later, the problem appeared again.

Since each drive appears to be temporarily resolved, it may be that the raid drive is incompatible with the RAID 0 structure, so I disconnect the storage stripe and format the drive inside. This removal of the hardware RAID interface seems to solve the problem, but the device is against the original intention, so I decided to find a way to preserve the raid function.

The previous operation did not allow me to find one of the SATA drives, neither in the BIOS nor in the operating system. Is there a problem with the drive? It turns out that my judgment is correct. The next day I found the seller and changed a new drive. Repeat the above process, reinstall the driver, set the storage strip, everything back to normal.

One day later. The write failure for the storage strip appears again, and this time another drive is having a problem. This time I switched the connection line of the drive device and the storage strip began to work, but only for a few hours.

Based on the above, I decided it was not a hard drive, but rather a hard disk controller. Since I used the motherboard for integrated SATA raid, I had to replace the entire board. The merchant gave me a new motherboard within 24 hours. Now I have to completely get rid of the system and remove the parts from the motherboard.

It took me two hours to assemble and disassemble the parts, but the system began to function again after installation. It appears that the above storage problem is caused by the RAID controller that comes with the motherboard.

Finally solved my storage problem. This system has been working for a long time. Now I'm concerned about how I can back up the 2TB online storage System if it's full.
