The computer merely had to be on for it to be working on it. #INTEL RAID MONITOR SOFTWARE WINDOWS#RAID on these alleged AMD and Intel platforms can exist entirely without an operating system! How do I know? When I lost a drive on both Windows 2003 R2 圆4 (ESB2) and Windows 2012 R2 (H87), the operating system took FOREVER to load because the Intel RST was preoccupied rebuilding the RAID1 array. ".in performing RAID operations." And here is the blatant lie. #INTEL RAID MONITOR SOFTWARE DRIVERS#".and software drivers to assist the OS." Like ALL hardware features do because something has to bridge the gap between hardware and software. ".combined with special BIOS configuration options." Right, because ALL hardware features need BIOS/UEFI implementation to be of any use. ".multi-channel disk controllers." Right, what all hardware RAID has to be to bridge the gap between components in the computer and the drives (SATA/PATA/SCSI/SATA/etc.) Since when was Ubuntu the expert of Intel and AMD technologies? I mean, just take a look at what you quoted and highlighted: That's like calling Phenom a "native" or "true" quad-core (quoting AMD). Under Linux, which has built-in softRAID functionality that pre-dates these devices, the hardware is normally seen for what it is - multiple hard drives and a multi-channel IDE/SATA controller. #INTEL RAID MONITOR SOFTWARE INSTALL#Older Windows versions required a driver loaded during the Windows install process for these cards, but that is changing as it has already changed in FreeBSD (which has FakeRAID support built into the ATAPI disk driver). This gives the appearance of a hardware RAID, because the RAID configuration is done using a BIOS setup screen, and the operating system can be booted from the RAID. Instead, they are simply multi-channel disk controllers combined with special BIOS configuration options and software drivers to assist the OS in performing RAID operations. Virtually none of these are true hardware RAID controllers. These have shown up in a number of desktop/workstation motherboards and lower-end servers such as the HP D元60 G5, if ordered without the optional RAID card. In the last few years, a number of hardware products have come onto the market claiming to be IDE or SATA RAID controllers. It's just a difference on what method you use to achieve a RAID configuration.įinal note: Make a new thread next time, please. RAID is always RAID no matter what way you look at it. but all in all, when it comes to the disks, all 3 handles RAID 0, 1, and 5 the same way. Software RAID can't be booted from (Linux can use it at root (/), but not as /boot.) but is easily ported between machines with different hardware. Hardware RAID handles RAID commands on the expansion card and has dedicated hardware for such commands as well as extra memory for caching and some support battery backup units to prevent data loss if power goes out before the buffer has been flushed to the disk.Ĭhipset and hardware raid tend to be more resiliant than software RAID and allows an OS to boot from it. Software RAID handles RAID commands at the kernel level.įake RAID handles RAID commands at the driver level by utilizing AHCI commands from the chipset RAID controller. The real differences come down to reliability and performance and what is handling the RAID commands. Generally speaking, Software, fake, and hardware raid all support your normal RAID tasks, such as keeping a RAID in sync, rebuilding after a drive fails, checking drive health, etc. In fakeraid, these RAID commands are offloaded to the CPU, which is fine in most cases, however you run into a few limitations depending on the OS you're using and what kind of fakeraid you're using. Not that I condone replying to this thread, you should have made a new one, but I'll reply.įakeRAID tends to do everything hardware RAID does however RAID controllers will have dedicated cache and CPU to doing RAID commands and calculating parity. With that said, there isn't much reason that you, as an average user have to worry about with the differences between fake raid and hardware raid considering most modern CPUs won't struggle in the slightest with fake raid, but real hardware raid will normally include a BBU and it's own ram for read and write caching, so hardware raid tends to be faster.Īll in all, go with the Intel raid controller. Intel raid (on your motherboard,) is something people in the linux world refer to as "fake raid" and what is does is that a RAID bios on your motherboard handles RAID commands using the CPU to issue those commands rather then a dedicated RAID controller, so under heavy read/write situations, disk I/O will use more CPU resources than a real hardware raid card would. The Intel RAID actually isn't real hardware raid, it just has a RAID bios to make it act like hardware raid, the driver and the CPU are still responsible for RAID ops.
