WD Scorpio Blue
Mobile Hard Drives
750 GB, SATA 3 Gb/s, 8 MB Cache, 5400 RPM

Big capacity for portable computing.

WD Scorpio Blue 2.5-inch drives offer high-performance, low power consumption and cool operation, making them ideal for notebooks and other portable devices.

Key Features

Massive capacity - Storage capacity for 2.5-inch form factor drives has arrived at a realm once thought to be impossible – up to 1 TB for mobile storage.* Whether they are in an external drive or a notebook computer, WD Scorpio Blue SATA drives continue to offer the highest capacity for space-hungry operating systems with plenty of room left over for photos, music, and video.
Quiet - In a notebook drive, silence is golden. WD's exclusive WhisperDrive™ combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market. These algorithms also optimize the way a drive seeks for data, which significantly improves power consumption. So now silence (and longer battery life) is golden.
Reliable and rugged - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks. WD's SecurePark™ parks the recording heads off the disk surface during spin up, spin down, and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved non-operational shock tolerance.
Fast and efficient - Ultra-fast 3 Gb/s SATA interface speed yields performance fit for demanding mobile applications.
Advanced Format Technology - Technology being adopted by WD and other drive manufacturers to increase media format efficiencies, thus enabling larger drive capacities. (PVT models only)
It will not be longer before we see 1TB Drive in notebooks.

Want this! Only $109

But could someone please explain to me this "Advanced Technology"?

Advanced Format Technology ...

Quote:
In a nutshell, it’s replacing the traditional 512 byte hard drive sector with a 4 kilobyte (4,096B) hard drive sector for a number of practical and technological reasons. Advanced Format is the name Western Digital is giving to drives implementing 4KB sectors.

The move to 4K-sectors has been some 10 years in the making, as research in the late 90’s identified that 512B sectors made less and less sense as drives continued to get larger. At a time when hard drives were measured in megabytes, 512B sectors were a good balance between technical factors and a desire to keep wasted space at a minimum (you can’t normally put 2 files in 1 sector), but times have changed and hard drive capacities are several orders of magnitude larger.

The crux of the problem is that there are 3 factors that are in constant need of balancing when it comes to hard drive design: areal density, the signal-to-noise ratio (SNR) in reading from drive platters, and the use of Error Correcting Code (ECC) to find and correct any errors that occur. As areal density is increases, sectors become smaller and their SNR decreases. To compensate for that, improvements are made to ECC (usually through the use of more bits) in order to maintain reliability. So for a drive maker to add more space, they ultimately need to improve their error-correction capabilities, which means the necessary ECC data requires more space. Rinse, wash, repeat...

XP requires some special software to run that.

Correct, but then most XP machines (due to chipset constraint) would not be able to support more than 137GB anyway.

There is already a 1Tb laptop drive, but it is 12.5mm thick, instead of 9.5mm thick, and beleive it or not, one of them is related to the drive you posted!!

Correct as stated from WD Support site

Quote:
*TPVT models are 12.5 mm high and may not be compatible with all notebook systems. Consult system specifications for maximum allowable drive height before attempting to install.
So be careful when buying one

Just align the partition like you do with an SSD on XP, before you install the image, free tools like Diskpar and Diskpart.

Come again


I read an article on some of the desktop models [I think it might have been TomsH ] and apart from gaining some capacity, everything else was pretty darned mediocre performance wise, WD also have a tool called WD align

I have been following this technology since Western Digital first anounced it. The idea is that you will have more useable space on a hard drive and less space eaten up by formatting. As an example, my 1 TB external only has 930 GB of useable storage whereas a hard drive with Advanced Format may have 970 or more useable GB. It will ultimately give you a little more bang for the buck. Here's hoping there won't be a miriad of compatibility issues stemming from this.

Just wish this came in a 7200 rpm version

But it's a nice, nice drive.
