Mediasonic HFR2-S3B Pro Raid Box is a 4 Bay Enclosure for 3.5 SATA I / II hard disk drive. The main feature of Pro Raid Box is its Raid function. It supports raid 0 / 1 / 3 / 5 / 10
Spanning Mode Spanning concatenates multiple hard drives as a single large volume; resulting in a seamless expansion of virtual volumes beyond the physical limitations of singularly connected hard drives.
Striping Mode Striping is a method of concatenating multiple hard drives into one logical storage unit. It is the automated process of writing data across multiple drives simultaneously. Striping is used to increase the performance of disk reads. The multiple hard drives will write data in “column” effect. If one drive in a striped set fails, all of the data in the stripe set is lost.
Mirroring Mode Mirroring is the automated process of writing data to multiple drives simultaneously. Mirroring is used to provide redundancy. If one drive fails, the redundant drive(s) will continue to store the data and provide access to it. The failed drive can then be replaced and the drive set can be re-mirrored.
Striped set with dedicated parity This mechanism provides an improved performance and fault tolerance similar to RAID 5 but with a dedicated parity disk rather than rotated parity stripes. The single parity disk is a bottle-neck for writing since every write requires updating the parity data. One minor benefit is the dedicated parity disk allows the parity drive to fail and operation will continue without parity or performance penalty.
RAID O - Spanning ModeStriped set with distributed parity Distributed parity requires all drives but one to be present to operate; drive failure requires replacement, but the array is not destroyed by a single drive failure. Upon drive failure, any subsequent reads can be calculated from the distributed parity such that the drive failure is masked from the end user. The array will have data loss in the event of a second drive failure and is vulnerable until the data that was on the failed drive is rebuilt onto a replacement drive.
RAID 1 + 0 RAID 1+0 is mirrored(Raid 1) sets in a striped(Raid 0) set .
Other Features:
1. POWER SYNC Powers off in synchronizatim with PC.
2. FORCED CONVECTION PROCESS Known for it's exceptional properties for being lightweight, high rigidity and superior heat dissipation capabilities, Aluminum is an obvious choice when it comes to constructing a quality hard drive enclosure, especially with the excess heat generated from the high-speed hard drives available in the market.
3. SMART FAN Comes with auto / manual modes & 3 levels of speed for best convention.
