The problem with RAID….
Hard drives are bound to fail. In a RAID-6 system, when a drive fails, it is simply “hot swapped” for a new drive, and the RAID software rebuilds the drive from information previously saved. However, the advance of technology has exposed problems with the RAID system, as follows:

As drive sizes have increased, the rebuild times have increased to the point that a 2 Terabyte drive may take at least 50 hours to rebuild.
RAID-6 with double parity reduces usable storage by 25 to 35% while also reducing write performance.
All drives in RAID systems must spin continuously, with the corresponding power and cooling demands.

AmpliStor, a new system for data storage from AmpliData, does not use RAID and does not require any form of replication. Instead it stores data, protected by Erasure Codes, which “transform a data object (files or blocks) into a longer message (typically a linear equation) with “n” data blobs…” Then, data can be recovered from a subset of the data blobs. It then uses “BitSpread” to store the data redundantly across a large number of disks, and “BitDynamics” to monitor capacity to ensure scalability.

This means, that Amplistor:

Reduces the risk of data loss to “.0073% or once 14,000 years”.
Saves power and cooling while increasing the lifetimes because disks do not need to spin continuously.
Increases the amount of usable storage because it uses 50 to 70% less storage capacity than RAID-6.
Reduces management effort.
