Note: 4Kn drives currently cannot be used as level-2 storage. In some cases, even up to 10 times faster. Whats new in PrimoCache 4.1.0: New: Support caching 4K native (4Kn) drives. But due to the fact that you do not need to simulate the full API of a disk device, the speed of working with such a disk increases several times. Such a disk will be visible as a letter, but will not be visible in Disk Manager as a device, that is, it will not work to manage it through the Windows Disk Management Console. Some programs, such as SoftPerfect, provide the ability to create virtual disks without simulating a full disk. In hard disks, the whole increase in speed or fault tolerance comes from parallel work with DIFFERENT physical devices, and in the case of virtual disks – you have one memory and one communication channel with it, it makes no sense to split it into several.Ģ. There will only be additional costs for calculating data blocks. Two virtual disks in memory lie on the same memory, and not on different devices, therefore acceleration cannot be purely on a physical level. It is also useful to create virtual disks as raw, and combine disks not broken into volume into a mirror.īut I repeat, in terms of speed, such a raid will be much slower than one virtual disk. When you try to make a software raid (any), using Windows, it will automatically offer to remake them in dynamic disks.
