You can use RAID 5 with different sized disks physically, but within the RAID features they all have to be identicle. What would happen in your case if you configured a RAID5 with all 6 disks, is that the RAID would use 6 x 2TB leaving the four 4TB drives with 2TB of free space....
RAID1 with different size disks Subscribe More actions idata Employee 09-17-2010 12:55 PM 1,563 Views I have an ICH7 family chipset with 82801GR/GH (at least, according to Windows Vista Home Premium 64bit Control Panel). I currently have two 500Gb SATA drives configured as RAID...
If you have four drives, information will be written to three of them. One of the four drives contains information to restore the array if it is damaged. If two failed disks appear in RAID 5, nothing can be recovered. On the other hand, RAID 5 with four drives is a very economical a...
Reads and writes can be performed faster than with a single drive with RAID 0. This is because a file system is split up and distributed across drives that work together on the same file. There is increased availability and resiliency with RAID 5. With mirroring, two drives can contain the...
RAID: The LDs under the controller card are reported to the OS, but pass-through drives are not. Mixedmode: Both RAID logical drives and pass-through drives are reported to the OS. In this mode, drives can be used in RAID and pass-through mode. Drives that are not configured with RAID...
The internal Seagate drive is reported with 476940 MB but the Samsung is reported again with 1 MB less, i.e. 476939 MB. The even more strange thing is that Win XP computer managements reports both drives with the same size of 476938 MB but this is again 1 MB less than the on...
Most drives are specified with thresholds for the access count (I/O operations per second) and data transmission rate (data volume transmitted per second). If the thresholds are reached when multiple processes concurrently access a drive, new access requests will be suspended, which causes drive ...
RAID 1 (Mirroring):Provides data redundancy by creating an exact copy of data on two drives. Ideal for critical data that needs a backup. RAID 5 (Striping with Parity):Offers a balance of performance and redundancy, requiring at least three drives. Good for businesses that need both speed ...
RAID 10 with 8 Drives: Maximum Drive Loss Analysis In an 8-drive RAID 10 array, the configuration consists of four mirrored pairs. This setup allows for a higher level of drive failure tolerance, as the array can sustain up to four drive failures—one from each mirrored pair—without any ...
User's Dell E520 appeared to have been fitted (from new) with two different makes of drive in the RAID1 configuration. One a Seagate, the other a Western Dig. Whilst they are the same size (320Gb) they are quoted as having different access times. The second drive has now failed, and...
