Hello, Thank you for reading this

I need to keep online 4 TB of data 24/7/365 year, I have a w2008 server with 4 x 1TB WD10EARS but in the last 10 months, I had two failures, both hanged the server badly and I have to remove the failed drive to be able to use it again.

The two failures where from different drives, and both where temporary, because after doing a full surface read/write (copying data from the disk with a file manager, erase it, and write the data back) the disk cleared smart (197: current pending sector & 200 multi-zone error rate) and started working normally again.

so I came to the conclusion that this drives are not reliable enough for 24/7 usage (you are probably leafing your ass off with that statement as it probably not anything new for you hehe)

so... what can I use (without going to savvio SAS incredibly expensive drives) to keep my data online reliably?

I was thinking on using 2x 2GB WD RE4-GP drives, but I really will like to know your opinions, since you are the hands on guys that really used hundreds of different disks, before go spending money on enterprise class drives.

I will really love to hear your comments, thank you!.

EDIT: I read here that drives with 4 platters are more prone to failure and WD RE4-GP 2GB has 4 platters 8 heads any comment on this?
Indkt.

My personal experience says that WD Re4 (and RE3 too) are a very good choice for stability, speed and reliability.
These are the ones i use on my personal machines and where i keep my personal and business files too (4x WD1003FBYX + 2xWD2004FYYS)

I'd love to hear others' opinions too, though.

Hi!, Thank you for answer!!, so you are using WD RE4 not WD RE4-GP right?, they are almost at the same price so it would be ok.

thank you for your input, anyone else?
