Although it offers more features and a better performance, it does need a controller card, meaning you would have to spend a little and do a few more configurations and more managing than with a software RAID. There are several notable differences and learning these differences may mean saving you time and money, and giving you more efficiency. If your budget allows, hardware RAID is definitely for you. Feel free to email us at [email protected] if you need a dedicated server with hardware RAID.

Want a Consultation or an Advice? The RAID controller does not take processing power away from the disks it manages. Thus, more space and speed can be used to read and write data. It can work on any operating system. Replacing failed disk is simple — Just plug it out and put in a new one. Software RAID has more failure possibilities and can be completely lost under certain circumstances.
I would still investigate the cost of adding one should be able to get a good deal on e-Bay and point out to TPTB the potential cost of not having it. You really need a Disaster Recovery strategy, especially in this case. Its slow down all process due to RAID process is being processed on the main processors unit , such as processing, copy, write, read, etc.
The reason is: 1. I know budget is low and cost is high, but keeping data is always available and healthy the most expensive of all. Perhaps you can schedule it on next fiscal year. Or if the critical data is not very big, you can consider using a cloud base backup. And have a secondary backup server that backup the main server daily every night. But you can use it on the mean time. Add more node, and sync the data between them. Using DFS replication for example. It is necessary to have the same identical controller in any other machine that you might ever want to transfer the disks to without having to reformat the drives first.
Some low-end controllers are managed solely by their Windows driver, which gives you the worst of both worlds: Inadequate performance, plus low portability to another system. First, before you do anything else, make sure that you have a good backup as well as verify that you can actually restore from it if needed. Besides the obvious of hw raid requiring hardware e. Specifically since you mention Win Server , there are some interesting to discuss.
How many IOs on average during the busy time do you see? Are you using legacy dynamic disk volumes with windows or are you looking to use the newer storage spaces storage management? With the newest version, you can have triple mirrors vs. Also, keep in mind that there are some other considerations for using sw RAID with windows on boot volumes that you would need to pay attention to.
That said, if you can get a PCIe RAID card do some shopping you can find some good deals on them that would be good, otherwise do your homework and implement sw raid if you have not done so, there are good tips over on msft TechNet site and of course, have a good backup! Hardware RAID is great if you have spare RAID controller exactly like the one in use and probably a third as well since you may be stuck with that array for a long time.
