Rather than racing the drive head across the disk as fast as possible, IntelliSeek uses rotational latency to its advantage, only moving the drive head as fast as necessary to get it into position for the next data point. Western Digital claims IntelliSeek can lower not only drive power consumption, but also seek noise levels and drive vibration.
Like most hard drives, the Caviar Green is covered by a three-year warranty. Our testing methods All tests were run three times, and their results were averaged, using the following test system. Vertical refresh sync vsync was disabled for all tests. All the tests and methods we employed are publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them. Only four points separates the fastest from the slowest here.
The Caviar Green is the slowest of the bunch in that test, trailing even its GB-per-platter forebear. ACDSee gives the Green a chance to strut its stuff a little. In the latter, the Caviar Green delivers exactly the same performance as the GP. Despite its platter density advantage, the Caviar Green boots slower than the GP by nearly five seconds.
That makes it one of the slowest drives of the bunch in this test. Fortunately, the Green redeems itself somewhat when we turn to level load tests. FC-Test gives the Caviar Green an opportunity to stretch its new platters, and the drive easily outpaces the GP in this first wave of write speed tests. The Caviar Green stays in the middle of the pack. Neither can a number of 7,RPM drives, for that matter.
Disk-intensive multitasking proves a little challenging for the Caviar Green. Our second batch of iPEAK workloads plays out much like the first. The Caviar Green struggles when a VirtualDub import is paired with other tasks, but fares better otherwise.
At least the Green is a lot quicker here than the original Caviar GP. Spindle speeds have little effect on burst performance. Power consumption For our power consumption tests, we measured the voltage drop across a 0.
This attribute also allows Western Digital to bring the Green up to a terabyte using one less platter, which translates into about a watt of power savings overall.
I expect the price gap between the drives to shrink as the new model becomes more widely available. The Green is really designed for applications that favor low power consumption and silent operation over raw performance. In its domain, it excels. For the green geeks just remember to keep things in perspective, there are better places to save power then your computer. Think about a watt power supply and how much you actually draw. My PC speakers use more juice then my hard disks and my hair dryer uses more power in a month then my PC does in a year.
Seriously keep things in perspective if you are looking to save power. Last year I replaced my appliances and in power saving the fridge is already paid for. Gas Stove and Dryer The stove I can still light during a power outage too! Lower Themostat 2 degrees Plastic on the windows for winter Check the draft seals on your doors Unplug shit!
I kid you not or put things on a power stripe with an off switch. Seriously disk drives are the last place to be looking for computers. If you have an ass-load of them I suggest keep on always on and set the others to wake-on-lan. Need a clarification regarding power consumption at idle. Is this the power consumed when the hard disk is still spinning but not seeking or has it spun down already?
I bought older 1TB GP disk for temporary storage purposes. Thanks for the tech lesson. This is a continuation of comments from the Seagate 1. And yea the other benchmarks may be more meaningful especially if one has specific uses in mind. However when a drive has better or worse access times based purely upon which benchmark is used it stands out and still plays a role in rating a drive which means a drive may appear better or worse based upon which benchmark is used.
Rotational latency is deterministic. Full stroke travel of the heads is deterministic. But random access time is not. As such an average value is typically reported, and is subject to systematic skew depending on how the tests are conducted. I thought a lot more people would find that intriguing or reply or want to know more about it. Oh well. Are you reading the same review as the rest of us, or are you just misunderstanding the purpose of the drive and looking for something to criticize?
Jeez man, not every drive needs to win the speed contest. Memory, hah. Given that the ambient noise is supposedly sufficiently consistent that the decibel readings are reused, subjective comments should be similarly consistent between reviews. Then again, the TR HDD review system probably has such a high noise floor that subjective differences may not be particularly noticeable, who knows. Well if your that bothered about app loading times etc then do what most other people who like this harddrive do.
Have a faster drive for your OS and programs, with this drive for your media and backups. If your in the market for a single drive to run everything off this isnt it. But then if you already have a fast system drive and just need more storage space for media or backups, this drive excels.
I see it as a middle-of-the-pack drive throughout all but the iPeak tests. I also see it as having the lowest power utilization of any drive in the comparison. Performance is pretty much as wash between these drives.
Installed the 2nd 1TB Green to serve as a real time Sync backup to 1st Green; not one problem, it worked beautifully [again]. I opted for the Green vs. System: Dell Precision WS, 3. Overall Review: I am very happy to date with the purchase and will not hesitate to purchase WD again [from newegg].
These are not the fastest drive around but they are quiet, run cool and are energy efficient I use a KillAWatt to measure server power draw. Overall Review: I heard dreadful stories about NewEgg's hard drive bubble wrapping; however I thought my drive were adequately protected. Add to cart. Price Alert. Add To Wish List. Best Sellers. Are you an E-Blast Insider? Get Educated. Close double click image to zoom in. See more " western digital green ". Its breakthrough 32 MB cache makes this hard drive suitable for high-performance home and business computing, as it can handle high-end data-intensive and multimedia applications.
The IntelliPower delivers a fine-tuned balance of spin speed, transfer rate and caching algorithms; IntelliSeek Calculates optimum seek speeds; and IntelliPark automatically unloads the heads during idle. All the features help the drive to operation in lower power consumption and reduced noise environment.
Perpendicular Magnetic Recording Perpendicular Magnetic recording technology enables industry-leading capacity in existing standard form factors and improves performance by increasing data density while reducing moving parts for enhanced reliability. Michael E. Eggxpert Review. Did you find this review helpful? Yes No. Robert B. Verified Owner. Did you? Overall Review: Solid drive, and Newegg is awesome as always. Pros: Quiet, Low cost Cons: Could be a bit faster on data transfer rate but still very adequate for a budget drive Overall Review: Very nice quiet drive for low price.
Fred S. Sleeper, or snoozer? Quality Control: -1 egg Only 1 year warranty : -1 egg Overall Review: Quality control does not seem to be confined to any one particular vendor, nor to any particular models. We are happy to see that companies are now expected to be somewhat environmentally-conscious. We love to see companies compete on metrics like performance per watt and we know we aren't the only ones who have an affinity for new architectures and designs that result in both efficiency improvements and performance gains.
It wasn't so long ago that efficiency and performance were almost always inversely related. In the end, we including the planet itself all benefit when people and companies try to be more green.
However, we know you didn't come here to read just about recycling, carbon footprints or hugging trees, so we'll move on to the topic of this review. Many PC hardware manufacturers are taking steps to become greener or at least help their customers green up, and Western Digital WD is one such company. You might wonder how a storage company like WD can do that.
Well, it's quite simple really: they offer a whole line of hard drives that use significantly less power than other drives on the market. WD gives the drives in this line the "GreenPower" label to indicate their reduced environmental impact. The nice thing about going green in this case is that the power reduction could lead to lower electricity bills.
With its high MTBF mean time between failures rating of 1. A very interesting feature of the GreenPower drives is IntelliPower, which is a "fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance" according to WD.
