raid 0 potential issue questions....

[Andrew Storlie]

ok so in my new build that im working on, in the 450d case, i have removed all the hdd bays so i can fit a rad and tube res. which leaves me the 2-2.5" drive slots on the back. i currently have 2-1TB 850 evos in raid 0 for a roughly 2tb size very fast drive. just surfing the web and reading about how "raid 0 is so bad cause of data loss or drive failure" blah blah blah. my question is, with modern day tech with GOOD brands like samsung, intel, corsair, etc... should i even be worried at all about a drive failing? samsung says 1.5 MILLION hours mean time before failure. thats like 171 years?????? i dont need a drive to last 171 years but a drive to last like 5 years of almost 24hour/day usage (light usage) would be a nice thing not to have to worry about......

If you're not storing any critical data on the array, and you're comfortable doing this, go for it. The issue stems from where your chances of a failure increase N times how many drives you have in the array, plus your controller. Software controllers are pretty hit or miss...I have seen some good ones on Unix/Linux/OS X platforms, but I've also seen some others that have crapped the bed and wiped out an entire directory structure, resulting in complete data loss on the array.

 

It all comes down to what you're storing, your backup strategy, and how fast you are able to recover from disaster, should it ever arise.

the controller is just the built in raid controller from the intel z97 chip set. i have no need for a dedicated raid card. 

 

and i do a FULL system wipe and install from a windows dvd every few months. this is a gaming pc that i have the raid in, so im not too worried. just something i like to know if i should be worried or not. i have a pc that i do my actual work on (im a CAD designer) and that pc is on a nightly back up to a 20TB nas

Hi there@Andrew Storlie!

 

I agree with Goose Legs - it depends on your backup strategy because any drive may die, no matter the technology. That is why you should build in a good backup plan, - any data that lives on one and only one drive, be it SSD or HDD, may be said to not exist at all. Especially with a RAID 0, which is an array that offers no redundancy.

 

However, since you have a 20TB NAS device and do a regular nightly backup (very good backup strategy in my opinion), you can go ahead and give it a try in my opinion.

 

Hope this helps.

 

Cheers!
