Appendix A Raid 0 (Select Models Only) - HP ENVY 17-2000 Getting Started Manual

A RAID 0 (select models only)
Select computer models with two hard drives ship in a RAID 0 configuration. RAID benefits
users who frequently work with large files and want to improve the storage performance of
their computer. With RAID 0, data is distributed across both drives. This allows data,
especially large files, to be read faster, because data is read simultaneously from both
drives. However, RAID 0 offers no fault tolerance, which means that the entire array fails if
one drive fails.
To enhance the write performance of RAID 0, Intel® Rapid Storage Technology has
implemented a volume write-back cache. The volume write-back cache allows writes to be
buffered and improves coalescing. The cache is enabled by default and can be disabled or
reenabled in Intel Rapid Storage Technology. An Uninterrupted Power Supply (UPS) is
recommended for use if the cache is enabled.
