WD Caviar Green 3TB Hard Drive Review

5 thumbs up

While solid state drives get faster, mechanical hard drives get larger. Not long ago, we celebrated the first 1TB hard drive, and since then, welcomed 1.5TB and eventually 2TB drives to the consumer market. Yes, the performance increase that SSD's offer is more than impressive. However, they still can't touch the capacity that traditional hard drives provide tech-savvy, budget conscious consumers and system builders. When it comes to cost per gigabyte analysis, hard drives possess a huge advantage over SSD's.


Western Digital Caviar Green 3TB Hard Drive

Today, Western Digital announces the world's highest density hard drive, as they reach the 3TB mark with their newest, 5th generation Caviar Green product. To go along with its massive storage capacity, the Caviar Green 3TB serves up a super-sized combination of reduced power consumption, lower operating temperature, and a quieter working environment. Read on to find out how well it performs and if it deserves to be on your upgrade list.

While the specs are straightforward, there are a couple of points worth mentioning. First, Western Digital is announcing two Caviar Green drives today. Along with the 3TB drive we're reviewing, there's also a 2.5TB model with the model number WD25EZRSDTL, selling for $189. Besides capacity though, the two drives are identical. Second, it's worth noting the Caviar Green 3TB drive makes use of the older SATA 3Gb/s interface, versus the newer SATA 6GB/s. But you won't hear us complaining about this omission, mainly because we've seen that traditional spinning HDD's still fall short of saturating the previous generation 3Gbps SATA interface. Next, let's dig a bit deeper into how Western Digital achieved the 3TB mark.

Pretty impressive. Though it would work best with a SSD drive in a desktopto get the best of performance and space.

Good review. It's a giant drive, but a 1TB WD Black seems to be a lot faster as a data drive. Adding two of them (1TB WD Blacks) gives lots of space and in RAID, should be speedier too.

Though I know it all has to do with maximizing profits, I wish WD would come out with their Black before their Green. I have zero interest in slower Green drives and do not particularly enjoy waiting. My 2Tb and 1.5TB drives are both nearing capacity. Hopefully I won't run out of space before they've finally wrung enough profits out of this Green drive to offer their Black drive to us unworthy peasants.

Hopefully it will be in the one fiddy range early next year. Maybe by that time I will have used up the 3Tb's I have now Cool

Dave,

Possibly I look at this a little differently than you, but my evaluation of this HDD is in terms of number of streams, noise, heat and Cost/BD. A 500 BD server would need five of these dudes in Raid 5. I am willing to pay $2/BD to store'em and serve'em and let me flush all of my boxes. That's my goal. It means that this 3TB drive needs to come in a little under $150. Come on Seagate. Let's have some stiff competition.

SadMan I feel like my 1TB drive should still be new.

I'm on the same boat as you, my hard drive is starting to feel like a dinosaur right about now.

Great reporting - I wonder if the same benchmark outcome holds true when the drive is in a RAID-5 configuration. To me, this drive is meant to be in a RAID5 Array; it will save energy and will render better performance than when used in a standalone configuration... what do you think?

I also would like to know (I may have missed it) where it is sold for $239?

WD doesn't like for us to put some of it's drives into RAID arrays. Many of the newer low cost drives that they sell 'all of a sudden' don't work in RAID.

If you do want a WD drive to use in a RAID array, you can spend quite a lot more for it.

Examples: 1.5TB WD Non RAID Enabled Drive costs $119.00 at NewEgg

But one that does RAID is: 1.5TB WD RAID Enabled Drive costs $239.00 at NewEgg

Same capacity, and same 64MB cache on the drive, but you pay a RAID tax to WD,......and this just started about 8 months ago. I found out the hard way with the purchase of four 2TB WD drives for a NAS box. Had to trade them back to NewEgg for Seagate drives that worked fine for my purposes.

So, Seagate is now my drive of choice for RAID setups.
