RAID 1 - If you are looking to inexpensively gain additional data redundancy and/or read speeds. A good base RAID level for those looking to achieve high uptime. RAID 5/6 - Web servers and high read environments. Generally will perform worse than RAID 1 on writes, so if your environment is write heavy or you don't need more space than is allowed on a disk with RAID 1, RAID 1 is likely your most effective option. RAID 10 - A good all around solution. It will also cost more than all the other options. It offers you additional read and write speed as well as a good level of overall redundancy. 4. This will greatly increase speeds, as you're reading and writing from multiple disks at a time. 5. You can then rebuild the array to a new drive off of the other drive with little to no downtime. RAID 1 also gives you the additional benefit of increased read performance as data can be read off any of the drives in the array 6. I buy on line from next tag I would chose to from HP DirectHP Pavilion HPE h8z PC with AMD FX-8150 eight-core processor [3.6GHz, 8MB L2/8MB L3 Cache]; 160GB SATA SSD RAID 1 (2 x 160GB HDD); 10GB DDR3-1333MHz SDRAM [3 DIMMs]; Genuine ... Price $1,299.99. Everything I need in one machine for at home use. 7. RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
