Major system upgrade!

Just thought I'd share... Some of you know I've been running a trio of "vintage" 1/2TB drives...
Today, I bought three WD Red 2TB drives...
Resilvering them in as we speak. So far no failures and no errors...
But my last 500GB drive sounds as if it's spinning against a Brillo pad!
Fingers crossed!

Good luck!

I see you have a Dell Precision. Would you happen to know where I can find covers for the 5.25 bays?

A T3500
You might try a local shop up here...

He has literally tons of server hardware.

Fantastic. Thank you.

I was just checking the specs on the WD Red. 1 million hours MTBF?
That's 114 years!

This is MTBF, be careful with a MTBF value... Most of the drives only last about 5-6 years before dying.

What do you mean?

MTBF = mechanical failure?
5-6 years = data corruption?

EDIT - Found one of your old posts.

Reliability

The MTBF is asked in Mh which stands for Megahours to avoid the need to input many zeros. It's the only field where you can put a decimal number.

The MTTPR (Mean Time To Physical Replacement) is the time needed to detect and physically replace a failed drive.

The MTTR (Mean Time To Recovery) is the sum of the MTTPR and the usable data space divided by the rebuild speed (this is the worst case, if you have a 50% full pool for example the rebuild time will be lower). It's not displayed for a Stripe RAID for obvious reasons...

The MTTDL (Mean Time To Data Loss) is expressed with the scientific notation because it's easier to read and to compare for very large or small numbers. It's not displayed for striped mirrors because it's a pain in the *** to implement :p

I mean that you can't just use the MTBF value as the drive's average lifetime. Look at the wiki article on MTBF for example ;)

This post is related to an app and explain what each field is. It has (almost) nothing to do with what we are talking here.

I realize that...just kinda funny. 114 years! Could you imagine @!
