Western Digital 2TB Caviar Green Drive Preview

Western Digital 2TB Caviar Green Drive Preview

Late last week Western Digital briefed us on their forthcoming release of a new addition to their Caviar Green family of hard drives.  No we're not talking some sort of exotic sushi or cracker-bound fish egg here either but rather a new, rather humongous and environmentally more friendly hard drive from WD, that can be considered an "industry first".  Today marks the day that standard rotational media breaks the 2TB barrier.  Let's spell that out a bit more clearly again here; T-W-O full Terabytes of SATA-based storage on a single, standard 3.5" hard drive.  Those of you on the consumer side of the market, hoarding gigs of music, movies, pictures and other media just got a bunch more breathing room to play with.  And those of you in the enterprise space now have a new option to consider with respect to bulk, low-cost, power-efficient storage.  Perhaps that rack just got a little smaller or the need to cool it a little less?

Today Western Digital is announcing their WD20EADS drive, otherwise known as the WD Caviar Green 2.0TB.  With 32MB of onboard cache and special power management algorithms that balance spindle speed and transfer rates, the WD Caviar Green 2TB claims a top rung spot on the density-per-square-inch and power-efficiency ladders. 

We've had an engineering sample here in house for a few days and have done some preliminary testing on it.  We'll be offering a full performance evaluation with the final revision of this new drive in the coming weeks but we have a sneak peek for you here.  Let's start with the specifications and then we'll take a closer look at the vital signs.
 

 

Specs:

  • Capacity:  2TB (400Gb/sq.in. areal density)
  • 32MB cache buffer
  • Variable spindle speed
  • 3.5-inch form-factor
  • 500GB/platter, 4-platter design
  • 3Gb/sec SATA with NCQ
  • SATA power connector only
  • PMR head technology
  • RoHS compliant

  


Formatted capacity - Windows Vista 32-bit, NTFS partition

Though our test system and the OS sees the drive as 1.81TB, as you can see here, there are over 2 trillion bytes of available capacity on this new, freshly formatted hard drive, with 147MB used just for the file system alone.  Below are some quick and dirty performance numbers with HD Tach and SANDRA.  We should underscore that we're testing a pre-release engineering sample here, so performance figures could scale higher as firmware revision are made to the product.


 
SANDRA and HD Tach Preliminary Performance - Engineering Sample, Firmware Not Final

A quick glance at the numbers here show this new big-boy Caviar Green drive from WD offering more than competitive performance versus the likes of Samsung's Spinpoint F1 and Seagate's Barracuda 7200.11 -- both 7200RPM-based products.  HD Tach shows an average read speed of 90MB/s and average writes at 80MB/s.  We'll be digging into performance metrics with other tools like IOMeter in the days ahead but this early view certainly looks good for a disk with this sort of capacity.  We'll be looking at power as well but WD claims this drive drops in somewhere around 7 Watts under read/write load and 5 Watts at idle.  With the ever-increasing demand for bulk storage, this new WD drive offers a smaller carbon footprint as well, with a full 2TB available in a single 3.5" drive. 

MSRP for the new ginormous Caviar is set at $299.  You can catch the official press release from WD, here. Stay tuned for the full HH monty with WD's new big-bad Caviar, coming soon.

For use all the space you need use GPT partition table, not MS-Dos partition table.

I only have about 500GB left on my 1.5TB HD I bought recently, so provided Western digital prices this well, I may have to grab one when they hit the shelves.

Any word on a 2TB Caviar Black version?

0

No word on the black version yet but MSRP is expect to be $299!

Yeah dependent on the price and my finances at the time I would love to have this drive and still want a 300g Raptor!!Plus a good video card at least a low cost 9800 video card!Hmmm dont want much do I? LOL Well I,ve learned a long time ago patience is a good thing cause I always of course want the fastest an i7 and the new Asus boards, I just need to hang around Raid he,s the one with the money! HA! HA!

Wow, that's looking pretty sweet -- awesome size and great performance (way better than the 1TB Green drives I reviewed a while back) to boot (no pun intended).

Looking great! Seagates probably too busy with their firmware problems to develop their own 2TB drive. I can't wait to see the Caviar Black Version, but $299US is alot! Tongue Tied

wow a 2tb drive thats nice!

$299 is cheap considering the SSD prices.

256mb for $495...

0

oo i was going to get the 1.5tb one, may aswell wait for this

0
+ -

I believe you mean 256 GB there BChase -- two different spectrums though. SSD = performance whereas these "old fashioned" drives are all about huge capacity.

Does anyone know what the RPM will be?

0
+ -

Variable spindle speed. I think like 5400 up to 7200, at least with the 1TB ones.

0
+ -

Yea they wont be over 7200. there is no real need on the bog HD's and it just casuses more ware on the drive. Like bob said 5400-7200rpm will be the speed of them

0

WD doesn't list that because the spindle speeds vary since it's a green drive and that is governed to reduce power consumption.

Dang, did know you had to be a computer geek to ask a simple question. Just wanted to ready more up on the issue as I have been following Seagate's issue etc. Sorry for being a simple person and looking for a reliable website to do some reasearch on.

Sorry then Char. This is the "reliable" site you're looking for then so ask away! :)

0

Dang, excuse me. I have never been on this site before had no clue how polite you could be. Like I really would know how reliable you could be as I personally do not know you. Let me try to rephrase the questions.

Do you know of any site out there that would provide me with some additional reading information on the WD 2 TB?

Thanks again for your advanced kindness.

No sweat at all, Char!  Sorry if I took you wrong there.  We're not too polite or stuffy around here actually.  Wink

We'll be offering a full performance evaluation here at HH, on the full production release version of the drive.  The unit we tested here had only engineering release firmware and was not final production product.  More to come in the days ahead when WD releases the final drive to us and we get it on the bench for some serious testing!

We all know HH is as legit as it gets so ignore the haters. I respect you and on that note, you're right... you probably shoulda just deleted the comment.

Just to clarify: The point I was making is that you're way above name calling.
