After how many month have you drive fails?

 

It is more easy to replayce a failed drive with a norco 4224!

 

But when you plan a new unraid it is more expensive to buy 4x Fivebay HDD rack and a pc case, as a norco4224.

The PC tower ist nice to see under the table.

When you have a normaly PC case, the hdd´s  are in normally cases, not hot swapp cases.

You spend more time to replace a failed disk with a normally pc case, as a norco rack.

 

How are the experiences to replayce a failed drive.

How long is your runningtime, when you replace a failed hdd drive?

 

 

In my experience, drive failures are not common at all, if you provide adequate ventilation to keep the drives temperature down. A lot more often than a drive failing, I have had some sort of connectivity issues. Typically a cable that needed to be re-seated or replaced (usually power, but it happened with data cables also).

 

Most of my drive-swapping (and therefore the incentive to move to cages) was not due to failures, but because I found that I often needed to replace existing drive with one of larger capacity. Also the server total weight was a consideration for me: don't like to lift / move the servers any more than I absolutely have to. They kinda heavy.   As usual ymmv.

it is not so much about a drive failing, it is about convenience.

 

It is also much more then just Besides replacing a failed drive.

Most people tend to start with a  few drives and then keep adding or upgrading a few more each month.

Drives are expensive and get cheaper and larger at a quick rate. it is cost effective to purchase them over time.

 

If you want to add a new drive (or upgrade a drive to a larger drive) when you have pull-put bays, it is a simple as pulling out a bay, adding or changing the drive and placing it back in.

But yes, it makes replacing a bad drive quick and simple as you pointed out.

 

Another big advantage when you use pull-out bays, you can wire it all up ahead of time and not open up the case until your next big hardware upgrade.

large servers with 10-24 drives tend to be very heavy and awkward to move.

When using internal drives, every time you want to add or change a drive you have move the server and open it up and play in the spaghetti of wires.

Something a lot of people don't think about when they put the drives internal, you will be moving wires around, plugging/unplugging a lot of connectors. Overtime connectors will be bumped/knocked loose. When that happens, you will then run the risk of data corruption.

 

Personally, i find computers and especially the hard drives in computers that I don't open up and work on often tend to last much longer then ones i keep playing with. Pullout bays eliminate that hazard for me. Once my servers are built and burned in, i hardly ever change anything in them other then the hard drives. After owning dozens of home servers, pull-out bays are a luxury i wont live without again. it just gets old quickly.

 

if you are questioning affording them, buy a case that you can add them later. build your server. then upgrade to pull-out bays when you can afford it.

As long as you use pre-clear to exercise your drives it should take years before one fails. You may have one failure per year. I use external drive bays because I never want to open my server case. Each time it is opened the probability of something breaking goes up dramatically.

I've had my system running for about...must be 4 or 5yrs now and I haven't had a drive failure yet.  Although to be fair I've replaced my drives with larger green ones except for 2.

I had two WD's fail in the same week and they were only about a month old.  Very rare though. 

Apart from that, I have some pc's that have hard drives that are about 12-15 years old and still going strong... I have the old bigfoots that still work..

The only drives I have ever had that have failed are these two wd's.... and seriously.. I have about 50 hard drives.. in computers ranging back to 386's...

I don't throw hardware out... I always buy a new machine... but hd's at least for me have been very reliable.. but still i would never risk data without at least some protection (unraid) and a backup of really serious data...(zfs raidz2).
