the same as those on a single hard disk. The difference is that the storage speed of the disk array is much higher than that of a single hard disk, and automatic data backup can be provided.Two features of RAID technology: First, speed Second, security Thanks to these two advantages, RAID technology was applied to hard drive systems with SCSI interfaces in advanced servers in the early days.

The same thing that I see is the case of the RAID card LSPCI stands for list PCI. Think of this command as "LS" + "PCI". This would display information about all the PCI bus in your server. Apart from displaying information about the bus, it'll also display information about all the hardware devices Connected to your PCI and PCIe bus. For example, it would disp
