Raid 1 is good because the failure of any one drive just means the array is offline for longer while it rebuilds, but can still be recovered and that the read performance is as good as raid 0. Besides, this raid is only suitable for raid 0 and raid 1. Some raid controllers speed up read access when using raid1. A raid can be deployed using both software and hardware. To achieve maximum sustained raid controller throughput for maximum bandwidth mbs use 64kb or larger sequential requests for maximum operations ios use 0. While the intel raid controller blows the software raid out of the water on sequential reads, surprisingly the windows software raid was better in nearly every other respect. Software raid how to optimize software raid on linux. Mdadm is linux based software that allows you to use the operating system to create and handle raid arrays with ssds or normal hdds. Software raid combines multiple drives into a logical volume through disk management feature provided by operating. Compare your ingame fps to other users with your hardware. Usually, hardware raid has better performance with the advanced raid levels than software raid.
This raid will also provide faulttolerance and improve performance. Mixing drive makes and models may work, but will result in faster drives being slowed down to. Industry standard pc benchmarking and diagnostic solutions since 1998. Multisocket platforms, faster processors, and one of the latest raid controllers. Favoring hardware raid over software raid comes from a time when hardware was just not powerful enough to handle software raid processing, along with all the other tasks that it was being used for. Hddscan can be useful for performing the regular health test. Raid stands for redundant array of inexpensive disks. The speed that data can be transferred between memory and a hard disk drive is one of a systems most important performance aspects. Supporting raid and supporting hardware raid are two different animals. This is a 5minute test thats supposed to find damages that occurred during the transporting of a drive. Hdd raid can increase performance from a low level to an acceptable level, while ssd raid may increase performance from an acceptable level to a very high level. If you are doing hardware raid this tool should be impossible to have work. Although were using a relatively fast test system, the configuration is not ideal to maximize io performance.
To deal with software raid devices, you have to install mdadm first, create the raid device manually, this has only to be done the first time. What about testing a raid speed, including software raid. The raid can be implemented either using a special controller hardware raid, or by an operating system driver software raid. It is a way to virtualize multiple, independent hard disk drives into one or more arrays to improve performance, capacity and reliability. A redundant array of inexpensive disks raid allows high levels of storage reliability. As one of the top tools utilized in the industry, disk benchmark identifies performance in hard drives, solid state drives, raid arrays as well as the host connection to attached storage. Before raid was raid, software disk mirroring raid 1 was a huge profit generator for system vendors, who sold it as an addon to their operating systems. It seems that no matter if you use a hardware or a software raid controller, you should expect to lose performance when youre duplicating every write, which makes sense. Trying some raid1 configurations, i want to know if the read speed is faster both on a single file and on several files. The program can test storage device for errors badblocks and bad sectors, show s.
Software raid is a type of raid implementation that utilizes operating systembased capabilities to construct and deliver raid services. Atto disk benchmark is a free speed tester software that can test hd, ssd drives, hbas, raid adapters, and storage controllers.

Soft possibly the longest running battle in raid circles is which is faster, hardware raid or software raid. It is compatible with all versions of microsoft windows. While the first aspect tells us if the hard disk drive performance really increases with raid0, the second aspect will tell us if this increase in disk performance if any will be translated into. However, there are still some niche applications where combining the speed of multiple, very fast ssds is helpful so in this article we are going to look at the current state of nvme raid solutions on a variety of modern platforms from intel and amd. As ssds have gotten faster, especially with the advent of nvme technology, the vast majority of users dont need to worry about raid 0. On the other hand, some raid cards introduce speed issues rather than solving them, we are way past the point where the cpu was important in raid setups, raid 1 has no calculation of parity anyway, so, unless you like to learn something and test various scenarios, dont even think of a raid controller for raid1 ssd. Ive personally seen a software raid 1 beat an lsi hardware raid 1 that was using the same drives.
