Raid 5 the best solution?

Hi, I am running a server with a terabyte right now, well the terabyte's file system just went corrupt and I almost lost all my family photos and everything, so now I want to buy 3 more terabytes and do a Raid 5 on them, so I can have a drive failure and so I can do it just for fun as a project. I stream video straight off the network to a computer on wireless upstairs, the old system did fine streaming will it do fine with Raid 5, will the write and read speeds be faster or slower than normal?

Here are is the raid controller card I was going to use http://www.newegg.com/product/product.aspx?item=N82E16816132013

I just kind of wanted you're guys advice on the whole situation and if I should go with a different raid setup?

Thanks in advance
 
Raid doesn't protect against random partition corruption. It is still best to have some sort of daily/weekly backup solution.
 
Depends on how fast your CPU is since that Rosewill card is what I call hardware-assisted software RAID. Meaning that all of the parity calculations is done by your CPU while the setup and maintenance is done by the card. Depending on your CPU, you're looking at anywhere from 15% to 60% CPU usage at all times for the parity calculations.

Anyway looking from the newegg reviews, which one should take with a grain of salt, the card averages Read speeds of 15MB/s with writes speeds of 8MB/s. Both are really slow. Maybe a bit too slow for streaming.

So if you want a fast RAID setup with room for expansion, I recommend getting the Dell Perc 5/i card off ebay for around $110 and two SAS to SATA cables for around $30. Hit up these threads for more info:

Don't do anything with the drives if you want to try to recover some/all of the photos. Use GetDataBack plus RAID reconstructor and you'll have a chance. I've recovered about 95% of the data off of a RAID 0 array recently with this software.

Well I actually already have a terabyte with a ton of info on it, if I include this array in the drive would, there be anyway to spread it out over all of them from that single drive? and for the bad hard drive sector, wouldn't that just be like a hard drive failure where you could reformat that specific drive?

Click to expand...

If you add that drive to an array, you lose any and all data on that drive. As for whether or not you can reformat the bad drive depends on whether or not it still works.
