Hello there!

I dunno if this question is applicable to this forum, but what brand/model of 3-4TB drive would you recommend based on your experience in terms of reliability?

1) One which is backed up.
2) One which has the best warranty.

For warranty in most cases I don't think it makes any difference. If a drive is sent back under warranty the replacement is nearly always some crap recertified drive which in my humble experience is likely to play up from day one and then fail with very little use. Warranty replaced drives are just not worth the hassle!!!

As for different brands and models i'm afraid it is just a lottery so the backup is all important.

buy them in duplicates, example, if you just need 1 drive, buy two of them at the same time, so you can do lot of things, mirror, donor board switching, etc, in case one goes bad.

Thanks a lot for replies! I'm about to buy 4 drives to use with NAS, in RAID 5 configuration. Options are WD, 3 TB, and Seagate, 3 or 4 TB. Any preference?

Hitachi is my preference for this.

Or WD Red.

I personally have not experienced with WD red for storage, so I don't know for sure, but have not heard any complaints either. I would not be afraid to go with WD either if you have the mula to get quality drives.

For Hitachi I have had several RAID storages with 2TB 7200 rpm Hitachi drives and have not had problems. 4TB have not had a chance, yet. The smaller one have not failed, yet, so I guess

I use Toshiba in raid 10, max 500 GB each (4 = 1 TB). For more capacity, I prefer to clusterize. Pros : maximum reliability, if power and environment is controlled - 500 GB per drive is a compromise, bigger are more problematic. Cons : higher cost, and they are not easy to recover.

conner and xebec..

Why Conner if there are still JTS around ?

I wonder how good could a RAID work on the ca. 1 GB latest Conner available before the company merge....

Thank you all very much for good advises!

I think I will go with WD Red, since it's made for NAS, I just wish WD had 4TB version too!
