I'm going to let the cat out of the bag right here and now. Everyone's home RAID is likely an accident waiting to happen. If you're using regular consumer drives in a large array, there are some very simple (and likely) scenarios that can cause it to completely fail. I'm guilty of operating under this same false hope - I have an 8-drive array of 3TB WD Caviar Greens in a RAID-5. For those uninitiated, RAID-5 is where one drive worth of capacity is volunteered for use as parity data, which is distributed amongst all drives in the array. This trick allows for no data loss in the case where a single drive fails. The RAID controller can simply figure out the missing data by running the extra parity through the same formula that created it. This is called redundancy, but I propose that it's not.
Since I'm also guilty here with my huge array of Caviar Greens, let me also say that every few weeks I have a batch job that reads *all* data from that array. Why on earth would I need to occasionally and repeatedly read 21TB of data from something that should already be super reliable? Here's the failure scenario for what might happen to me if I didn't:
* Array starts off operating as normal, but drive 3 has a bad sector that cropped up a few months back. This has gone unnoticed because the bad sector was part of a rarely accessed file.
* During operation, drive 1 encounters a new bad sector.
* Since drive 1 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector.
* The RAID controller exceeds its timeout threshold waiting on drive 1 and marks it offline.
* Array is now in degraded status with drive 1 marked as failed.
* User replaces drive 1.Read more ›
For my home-made FreeNAS (google it!) NAS/Server, I bought 5 WD Red drives from Adorama (purchased through Amazon) and 1 drive directly from Amazon.
The one drive from Amazon came very well packaged, double boxed in what looks like a WD cardboard box with a shock absorbing cradle. Very well packaged for shipment. Honestly, Amazon has been stellar for packaging boxes for shipment.
The 5 hard drives from Adorama came in a big box which 'clunked' when it was tilted. Opening the box revealed some big plastic pillow air strips, and 5 loose smaller boxes. Inside each of the smaller boxes was a few pillows and a factory bagged hard drive. There were not enough pillows in each box to securely cushion the hard drives against rattling around, so there's a high likelihood of damage in shipment. BAD SHIPPERS! NO DONUT!
Anyway, getting on to the performance of the drives... I'm running 6 drives in a ZFS RaidZ2 array. They are all controlled using an IBM M1015 PCIE 8x SATA 3 controller which has been flashed to be an HBA providing JBOD to the ZFS OS. That's a lotta acronyms! The speed of the array is quite fast...Read more ›
I just purchased a second drive and did some testing on it while blank and uploaded the results under customer images to the right.
Once again the "load cycle count" issue has returned to their line of drives. If you don't know what this is you can Google, but basically the drive repeatedly parks the drive heads, thousands of times a day, because of an improper firmware setting on the drive. The drives are only rated to 600,000 load cycles and with them ticking of once every few seconds the drive will exceed its rating in less than a year.
This can be corrected by the user but it is a pain and requires you have certain hardware/software to do. Probably beyond most users. Exchanging the drive may or may not help because you have no idea if the next drive will have the same erroneous setting.
This has happened many times in the past few years, check the reviews for this and other WD drives. WD acknowledges this is the incorrect setting as do many NAS vendors that recommend these drives. And yet, WD can't seem to help itself from setting the IDLE3 parameter wrong every few months. This is a sign that they simply are unable to perform basic configuration management in their production facilities. If you can't manage that you don't belong in the HD business.
For reference, Google WDIDLE3 for how to fix this problem - but you better have a machine you can boot to a DOS image in order to use it. Alternatively return your WD drive and buy the equivalent Seagate drive instead. They have a nice NAS ready drive equivalent to the WD Red and they know how to set IDLE3 correctly.
