Default 2x Seagate 1TB in RAID 0 vs 1x WD Black 2TB

EDIT: this if for STORAGE (already booting off of a 128GB SSD)

I'm new to this whole RAID thing but from what I gather, it should give me a performance boost vs just normally setting up the two drives.
How about when compared to the WD Black? Will the RAID 0 beat it? Apparently, the WD Blacks lack TLER so are not suitable for RAIDing.


My applications are mainly video editing. I am aware of the data lost risks associated with RAID 0, but I'm looking for PURE PERFORMANCE here.


If RAID 0 is recommended, which Seagate drives should I use? I'm not too familiar with the various models.
I have read that the Samsung Spinpoint F3 is the best drive to use for RAID 0, but unfortunately I cannot obtain this drive in my country.

Thank you.

Depends on the drive. You get a not-quite-doubling of sequential I/O performance. Latency is about the same though. Just saying "Seagate" isn't super helpful, since they have oodles of different-performing drives.

Might be a good place to start if you're trying to find the numbers for a specific model.

Many types of non-pro (Intel ICH or Software) RAID controllers will circumvent/work around the absence of TLER. I'd probably do that - the random/seek performance of the WD drives looks like it would be noticeably better.

My advice is never go Raid0 unless you're forced. Raid is best left to the enterprise. How much ddr3 do you have? If you want pure performance for your video editing then a RamDisk is king.

If you care about your data do not use a RAID0.

If you need more performance put the files you care about on the SSD(or a new 2nd SSD) or consider a RAMDISK.

I have 16gb of ram so I will be using ramdisk. I already have an ssd for the Os. What I need is more performance over and above that. I will back up the data on to a slower drive so data integrity is not my priority. I'm looking for pure performance. Will a raid 0 give me very much more over just a single black?

A second ssd is not an option due to the large sizes of files I'm dealing with.

If you care about your data, it doesn't matter if you use RAID because you will have backups.
