completely independent of the host's CPU resources. RAID 7 can be viewed as a storage computer (Storage Computer), which is significantly different from other RAID standards. In addition to the above criteria (table 1), we can combine a variety of RAID specifications, such as RAID 0+1, to build the desired RAID array, such as RAID 5+3 (RAID 53), which is a more widely used array form. Users can generally gain a disk storage system that is more responsive to their requirements by flexibly config

loss than RAID 5, so "write performance" is very poor. 　　Poor performance and complex implementations allow RAID 6 to be rarely used in practice. RAID 7: This is a new RAID standard, with its own intelligent real-time operating system and software tools for storage management, can be completely independent of the host running, do not occupy the host CPU resources.

It can run completely independently of the host and does not occupy host CPU resources. Raid 7 can be viewed as a storage computer, which is significantly different from other raid standards. In addition to the above standards (such as table 1), we can combine multiple raid specifications like RAID 0 + 1 to build the required raid array, such as RAID

Winmtr 99: Through the winmtr 99 test, we can understand that after raid is set up, both the commercial disk performance and the high-end disk performance have been greatly improved. The raid 1.5, composed of two Gold Diamond 9, has the strongest commercial disk performance, reachi

used array form. Users typically have the flexibility to configure disk arrays to obtain more disk storage systems that meet their requirements.Initially, the RAID scheme is primarily for SCSI hard disk systems, and the system costs are more expensive. In 1993, Highpoint introduced the first Ide-raid control chip, which was able to use relatively inexpensive IDE hard drives to build a RAID system, greatly reducing the "threshold" of raid.Since then,
