They are trying to give you a 3TB green to replace a 2TB Black ? If you have another boot drive, I would accept the 3TB for pr0n

Seriously, I would argue and ask for a black since 3TB can be hard to fill and you could always get another 2TB Black and raid 0 for speed and storage like I'm doing.

For boot, I wouldn't use the Green.

Yes, there's a major speed difference.

But if he can get one, then why not?

Ask them to send you a 600GB Velociraptor instead.

(Oh man, the resale value! Or you can keep it and enjoy having the best SATA HDD out there.)

Capacity is useless without speed. 2x 1TB Blacks would be another great way to go, but I don't think they can send you back two HDDs for one RMA?

Figures. I keep hearing bad things about those Marvell controllers. (88SE9128?) Lots of people with SSDs or HDDs have issues with them. I think in the past week there have been several people with those controllers/ports dying?

There's one of the threads - but I've seen a few more.

save starting another thread sorry, is thier a difference between green and blue WDs? Apart from energy savings with greens, i have a mixture of black and blue WDs. Black for system, 2 blues in RAID1 for DATA in my PC!!!!

Greens have low idle timeouts. After 8 seconds of inactivity they park their heads. This makes them incredibly unreliable in RAID.

The solution is to disable that feature (takes extra work - the WDIDLE3 bootable tool is required) or you can spend a bit more on drives that don't require that tweak.

For some operating systems (like Linux) you should turn the idle timeout off regardless of RAID - Linux wakes up drives every ~20 seconds, which will send WD Greens to an early grave. (4320 head parks per day, 1,576,800 per year... how durable do you think these things are?
)

Gotya. so WD Blues (not green) are ok for RAID1 DATA array in my PC? I also WD blacks in a NAS server running 24/7 going well

RAID-1 works well with almost any drives. Worst case scenario, if for some reason your array breaks apart, you've got a full copy of your data on both drives. You just pick which one to rebuild from, then start the process.

WD Blues will only lock up like that when bad sectors are discovered. Once you've got those you should start considering an RMA. WD Greens will lock up on bad sectors or from head parking. It's just a question of whether they do it long enough to knock apart your array. If they do, your drives have to spend time rebuilding the array - that's lost performance, a brief period where your data isn't redundant, and you're spending time telling it what to do.

For many people it's not worth it to save a few dollars. There are quite a few stories of WD Greens dropping from arrays after a half-year or so. That means there's probably about a 1/500,000 chance that a head park takes too long and the drive drops out.

WD Blacks generally work well for that.
Bad sectors are not common on those drives.

That's weird that a bunch of them are just dying. I haven't had any updates for it, so I don't know what changed. Working fine for almost a year, then up and dies. Still have to pay to return one of the drives, so no point in not keeping the new slightly faster one.

Now to figure out if it's worth a RMA for my motherboard.
