Everything was implemented and tested using HP Smart Array P420 with 8.00-0 firmware version. I don't know if it will work correctly for arrays operated with different controller or firmware version.

Changing from a RAID 0-array boot drive to a single-drive boot should be easy, I thought, but the operation can be more complicated than may you anticipate. Here's what I learned from the experience.

The second step is to backup the data on the RAID array before replacing the battery. This is a precautionary measure to prevent any data loss or damage during the replacement process.

RAID 6 uses dual parity and can handle two drive failures within the array. Some RAID systems can also improve read performance because data is available from multiple sources.

Hello I've got two 500GB Sata drives in raid 1 on a HP ML110 G6, and I need to replace one of them as it is reporting as failed. I got two new Segate Constellation ES.3 128Mb 1TB, that i could use ...

Big storage companies stopped recommending RAID 5 a couple of years ago. But I still see small 4-drive arrays touting RAID 5 for home and small office use.

Caching makes your RAID array go faster. But if you lose power your data can be corrupted. The old solution: a battery. The new and better solution: flash memory - with a twist.

RAID 0: you need at least two disks, and data is striped across all of them. This configuration has excellent performance because the disk controller can go immediately to the sought after data.
