Strongly recommend raid 5. strings drives together but you lose one for redundancy. RAID 0 is good but if one fails, you're SOL

Greeting. Im having hard time about Raid 0. Is it true that Raid 0 has a greater HHD failure rate than non Raid HDD aside from its double speed? I just cant clarify it myself. Thanks.

the probability increases because you are using two drives instead of one. Do not raid 0 cheap drives like the WD blue.

With good quality drives you won't get a failure before your next upgrade, I'm talking about drives designed for RAID such as the WD red and RE drives.

Yes. but is Raid 0 affect the HDD durability?

RAID 0 has no significant impact on a HDD's life span, so the drives themselves are no more likely to fail than operating as individual drives. What does increase is the chances of losing data, as if any drive in the array fails, data is lost. RAID 0 does not increase HDD failure rate though.

Raid 0 won't affect HDD's life span but it will rape the living life out of a ssd. If you're worried about losing data raid 10 or 01 (however you wanna put it) is your best bet.

Really wouldn't recommend RAID 10. It's wasteful, inefficient and has pretty bad average case failure overhead. If you're going to be using 4 drives, RAID 5 is really the best option in terms of capacity, speed and failure overhead. Rebuild times can be a negative if a drive fails, though.

If he's gonna use it for gaming and OS then no need for a raid 5 or just be like me and run a raid 0 and have a 1 tb to back it up at different intervals.

It's always a matter of do as I say and not as I do xD

 

I have my OS on a RAID 0 array, which is a terrible idea. 

 

If the system is just for gaming and normal use, I wouldn't recommend RAID at all. Just a good backup is sufficient for non-critical data.

lmao true true but I like raid xD so I raid 0 my game drives + my os drive and I have 2 4 tb's backing those up.... That's another system and not my main.

Hi there :)

 

Just to pitch in with a few comments:

 

RAID0 is designed solely for performance increase with no redundancy at all. The data is split between all drives and written simultaneously on and read from all of them at the same time, boosting the sequential speeds and with little effect on random speeds. This has one big plus and two big minuses:

- You get a great boost in sequential speeds which is great for usage types such as editing and rendering as they benefit mostly from sequential speeds.

- In case one of the drives in the RAID fails or drops out you lose all the data across all drives which increases the chances of data loss by a lot. Add to this the workload added by using the drives in a RAID configuration and you have more than double the chance of data loss when using tow drives in a RAID0 config compared to using them separately.

- Most everyday usage types rely mostly on random read/write speeds over which RAID0 has little effect so you won't be noticing major increase in general performance. Booting from a RAID0 array is often slower as the RAID needs to be initialized first and then the system can proceed with the boot process. 

 

Unless you need specifically a boost in sequential speed or have a good backup setup I would suggest to try to avoid RAID0. 

 

A word on RAID5 too: 

This is a good option for home usage as it both offers good performance boost like RAID0 and offers redundancy on a single-drive failure. There are two major down sides of RAID5, though: 

- it requires at least 3 drives to work and sacrifices the capacity of one whole drive for the redundancy.

- the rebuild time of RAID5 is extremely slow as it may take up to 30 hours for a simple 3-drive RAID to rebuild after a drive failure and during that time if a second drive fails you will again lose all data across all drives. 30 hours is a lot for a constant rebuild process and the drives are put under extreme workloads so this is a real issue to consider. This is why people are more and more moving towards RAID6.

 

Let me know if you need any other info or have any questions!

You are most welcome :)

 

JBOD or non-RAID (same thing) is what most people use in their systems with other drives such as external HDDs or network storage devices used for backups. Make sure you have such a backup if you have data that you don't want to lose. Facing data recovery and problematic storage drives is not something you want to do. 

 

Let me know if there's anything else I can help with!
