This is SATA3 model(wd20earx), speed up to 6GB/s
Considering that the WD20EARX doesn't even come close to reading or writing at 6Gbps (750MB/s) nor 3Gbps (375MB/s) nor even 1.5Gbps (187.5MB/s) and in fact reads and writes on average around 80MB/s… it doesn't really matter.
That said, I've yet to see a real world comparison between the two. So there may be a performance difference. But the 3/6Gbps issue won't mean dick.
I understand that technically SATA3 can be a couple of percent faster even if the drive's burst rate is under 375MB/s (perhaps because latency is the time taken to read the sector plus the time taken to transmit plus overhead across the SATA, so a faster bus can reduce this overhead by a fraction of a millisecond). http://www.overclock.net/hard-drives-storage/898768-wd-cavia…
However, if you really care about 1% or so of performance you really shouldn't be using this drive. I think the 6Gbps should be removed from the title, as it is misleading and the least important spec of this drive. E.g. the RPM and operations/sec are way more important.
That's for: 2Tb WD Caviar Green WD20EARS SATA 3Gb/s 64Mb Cache dude! This is SATA3 6GB/s wd20earx. ;)
Ah my bad, must look at finer detail next time ;)
+ve then!
Previous deal was for a SATA2 model (WD20EARS) whereas this one is for a SATA3 model (WD20EARX). So with this price even including shipping it is a good bargain.
Just bought 2 sata2 units last week, anyone know the speed different between sata2 and sata3 and sata6???
SATA revision 1.0 (SATA 1.5 Gbit/s)
SATA revision 2.0 (SATA 3 Gbit/s)
SATA revision 3.0 (SATA 6 Gbit/s)Also note, it's Gb/s NOT GB/s (BIG DIFFERENCE).
As for SATA 6.0, well, some say it's over 9000 Gbit/s.
Over 9000??!!
According to thsi article: http://www.hardwarezone.com.au/reviews/view.php?cid=6&id=306…
the paragraph::
"This limitation of the chipset poses a problem for the SATA 6Gbps and USB 3.0 controllers. They each require the full 500MB/s bandwidth from a single PCIe 2.0 lane to reach their maximum speeds. If these controllers are connected to the P55 chipset, they can only do so via the chipset's PCIe 1.1 lanes, which are capped at 250MB/s per lane. It's either that or connecting these controllers to the processor's PCIe 2.0 lanes, which will then affect the reserved graphics bandwidth."depending on your mobo, you will see no difference or your graphic card performance will be lowered
however if you got the other mobo (p7p55d-e or similar):
"ASUS meanwhile uses a bridge chip on the P7P55D-E Premium to enable what it calls 'true' SATA 6Gbit/s and USB 3.0. What this bridge chip does is to convert four PCIe 1.1 lanes on the chipset to a bandwidth equivalent of a pair of PCIe 2.0 lanes. These can be used by the new SATA and USB controllers for the full bandwidth. Of course, this is still a compromise and technically not perfect, since these lanes have to come from somewhere but chances are, users are probably not too concerned about the loss of their PCIe 1.1 slots for example or the lanes from the Gigabit LAN (since there are two LAN controllers on the ASUS). The bridge chip however is additional cost that may be reflected in ASUS' pricing."you will see some difference when havign stuff from and retriving on the 64mb cache.

edit: it pasted something i didn't want pasted >.>
Does this mean no go for HP Microserver?
Its backward compatible with SATA II, but you're better off finding cheaper deals for the Microserver.
@stumo;
http://www.staticice.com.au/cgi-bin/search.cgi?q=2TB&spos=3What I'm trying to get at is no point buying a SATA III drive for the MicroServers as they won't be able to use them.
@bragains
What cheaper deals are those?
Zero. A green hard drive is never going to saturate a sata2 connection. Getting sata3 over sata2 for this is therefore entirely pointless. Sata 6 also doesn't exist.
You have Sata2 which has a theoretical transfer rate of 3Gbit/s (~375mb/s) and Sata3 which has a 6Gbit/s (750mb/s). Now given the most this hard drive will ever read/write as is around the 100mb/s mark.. you can see the pointlessness of such a thing.
USB3 over USB2, however, is a completely different story.
fully agree…. I wonder why they developed sata3 when sata2 isnt fully saturated (at the very best sata2 is 1/3 or 1/4 used… the average pc will struggle to get 100MB/s especially if there is an antivirus program fiddling in the background)
one word… SSDs
That is not one word, that is one acronym for three words.
:P
I'm not sure what's funnier lol…
1. That you thought I was being serious saying "one word" or…
2. That you took the time to post about it.here for details.
http://en.wikipedia.org/wiki/Sata_3SATA 1: max read/write = 150 megabyte per second. Disk based HDD don't even reach this speed yet. This is too slow for SSD.
SATA 2: max read/write = 300 megabyte per second. Current gen SSD read/write at 287/275Megabyte/sec so it's almot saturating the BUS. This is too fast for regular HDD.
SATA 3: new gen SSD will be release this year 2011 and the speed will exceed 500 Megabyte/second. SATA 3 is released in anticipation of the new gen SSD, and does not have the older regular HDD in mind.
Great deal, IMO beats the other one if you're in Victoria.
how do you find out if you motherboard/machine supports this hdd?
SATA 3 is backwards compatible with SATA 2, it works even if you do not have SATA3 support on your motherboard.
fully agree with purplebangle postage in Vic is $5.50
…. just have to decide whether I need another 2tb …. lol ;)
Does SATA3 need certain mortherboard to support, or it works on any mortherboard? Im running SATA2 harddrive, not sure if SATA3 harddrive can be supported
refer to scrimshaws comment - sata3 is backward compatible…… it will work on sata2
IMPORTANT INFORMATION ABOUT SATA3 HARD DRIVES - IE. THIS ONE
They work fine with any motherboard!! That is all.
any motherboard?
BRB while I find one of my old motherboards with no SATA at all.
Fluidtek also doing Seagate 2TB for $90 in store.
.
.
I've run out of sata ports on my mobo so I guess I'll have to pass on this one.
I believe I'm using 3/4 or 4/6, but still going to pass. I need a NAS first! Every time I find a good price I decide to wait just a little longer.
Yuck for Green drives.
I don't get why you guys are negging me.. but green drives have a much higher failure rate than non-green drives, they're also slower compared to normal drives.
I agree - green drives blow chunks in a massive way. I have two Seagate greens and it literally takes 10 seconds for them to list a directory of 100 files more often than not.
I would never consider buying a green drive again…
You can get Hitachi 2tb 7200rpm drives for $129 delivered or less - much better option although substantially more expensive.
Can't you just paint them red? I've heard that everything red goes faster! :p
GREEN is just a marketing term for a SLOW 5400 rpm.
It's too unatractive to the customer to tell you how terribly slow it is
so they came up with the "GREEN" for power saving. To sell you on the
global warming climate change crap…@mellosweep
Not only that, your HDD spin speeds adjust to adapt whatever you're using according to my friend.
Apparently, constantly fluctuating spin speeds is very bad for the hard drive. I guess green drives are okay for storage, but i would never use one has a primary harddrive
Although not an ideal choice for storing programs, if you're aiming for a particularly quiet computer, an SSD + sub 7200rpm drive is definitely beneficial.
Exactly, horses for courses! :)
How long is the sale on for? Can I buy it online and select to pickup from store? Thanks.

According to the WD spec sheet for this drive, its burst speed is 110MB/s (0.88 Gb/s) which is only slightly over half of SATA 1's 1.5Gb/s limit. Simply put, these drives (and most others on the consumer market) wouldn't even challenge SATA 1's limit, let alone the even higher SATA 2 or SATA 3 limits. Just marketing BS. The drive, being newer technology may have other advantages over the EARS ones, but data transfer speed is certainly not one of them.
It says on their site, front page says to call but on another it says that they are out of stock. Also it's not bad for just a storage drive (for the reasons Karlston stated above) but I wouldn't be looking at it for a primary unless your computer is a bit old.
Yes, we are run out stock at moment.
Correct me if I'm wrong, but I'm pretty sure the green sata3 drives don't suffer from the intellipark issues associated with earlier models. Too bad its sold out though.
