"All drives fail, it is only a matter of time....."
I don't know if there are "best" drives available or not, but the following is what works for me.
Many drive manufacturers have recently reduced the warranty periods on their drives so that now the "standard warranty" is about 1 year.
At the time the choice was made it was said that many people replace drives for larger and faster ones often, and that even though the warranty period is reduced the drive will last as long as before, it will just get rid of some costs incurred by manufactuers.
I still like warranties that are longer than 1 year.
It seems that Western Digital has a convention going that their "standard" drives have a warranty of 1 year, "Special Edition"/SE drives have a warranty of 3 years, and the "Enterprise" drives have a warranty of 5 years. Costs, of course, change as well but I tend to view the warranty period as confidence in their hardware.
For decades, Seagate has been a staple of mine.
I have had pretty good luck with Seagate drives. I have "retired" far more drives than those that have failed me.
For much of that time I also purchased Western Digital drives as well, and IBM.
Western Digital was off my purchase list for a while when they had the problem that got through regarding the 6gb and 8gb drives. I WAS NOT happy about that, and thought at the time, I would likely nevery purchase one again.
For a couple of years I DID NOT purchase any Western Digital drives.
IBM sold their business, so they are not available.
(I am not looking for any arguments, "the drives being made are the same design, it's just a different manufacturer". I understand that, but that is NOT important to me.)
Western Digital came to the top of my list recently when they introduced the Raptor drives.
Not so much that they were fast 10,000 RPM drives, but from my point of view it was because they were fast 10,000 RPM drives, with SATA, and with a 5 year warranty.
Because of that single success, my current manufacturer list is:
Western Digital
Seagate
Overall the purchasing pattern will become about 70% to 30%.
I also used to like Quantum hard drives. When Maxtor and Quantum merged I purchased a Maxtor drive. It lasted about 1 year.
The drive failed, under warranty, a couple of weeks ago.
For nearly 11 years they were on my DO NOT BUY list. They are back on that list again.
It may not be a valid test, or valid reasoning, but it is what it is.
One thing I REALLY like about the Seagate drives is that they have a whole bunch of drives that are entirely encased. (Maybe all of them?)
It's not that circuit board damage to hard drives occurs often, but I like the idea of it not being a concern. Just little encased storage bricks.
Mirroring is so common-place now a days that virtually every motherboard supports it, and optional controller cards are easy to be had for very little money.
There are only two sources on my drive list currently. I would like to have more on that list, but I don't see any else out there that interests me at this time.
I hope that helps?
