Product Description

WD Scorpio Black 7200 RPM SATA 2.5-inch hard drives from Western Digital combine a lightning-fast 7200 RPM spin speed with a SATA 3 Gb/s interface and 16 MB cache to deliver desktop-class performance. With 5400 RPM-equivalent power consumption there is no compromise in battery life. In addition, WD Scorpio Black hard drives are designed with ruggedness, reliability, and data-protection features that actively watch over valuable data. Available in capacities up to 320 GB, these hard drives are perfect for laptop users who require maximum capacity and lightning-fast performance. Free-fall sensor - As an added layer of protection, if the drive (or the system it's in) is dropped while in use, WD's free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head to help prevent damage and data loss.

Customer Reviews

Fast & Quiet
This review applies to model WD3200BJKT not Model: WD3200BEKT which does not have the free fall sensor

----

I purchased this drive to replace the 100gb, 7200 rpm Hitachi that came with my Dell Inspiron 9400. So far the drive has been equally as quiet, a little bit faster and of course much larger. I have noticed none of the vibration that a another reviewer noted. I have reinstalled Windows XP Pro on this hard drive at least five times in order to give the drive a good test copying and modifying files. So far this drive has passed every test with flying colors.

Pros:

Size - 320gb = lots of storage space.

Warranty - 5 year warranty (unheard of in a laptop hard drive)

WD's ShockGuard(tm) technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.

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 shock tolerance.

Free-fall sensor - As an added layer of protection, if the drive (or the system it's in) is dropped while in use, WD's free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head to help prevent damage and data loss.

16 MB cache

In short, I am very impressed with this drive!

WD 320GB 2.5 HDD with free-fall sensor WD3200BJKT
This WD Scorpio Black WD3200BJKT hard disk has been working great for several months now. I installed it in a Macally B-S250SU Hi-Speed eSATA/USB2.0 Storage Enclosure for 2.5inch SATA HDD to host several development virtual machines (VMs) containing application server and IDE. Being so small, and particularly in this very small enclosure, the free-fall sensor provides assurance in preventing damage to the disk in case of a bump or if moving it out of the way while running or accessing the disk. This kit runs of a single USB port without a single problem given the low voltage use of this disk during ramp-up. I would definitely recommend and purchase again.

Fast & Efficient Drive
I was a bit skeptical about this drive after a lot of people were stating that it wasn't that much faster than the 250GB Seagate Momentus 5400.4. Anyway I followed my mind and I wasn't sorry, because this drive with it's 16MB cache 7200rpm was a step faster in the tests I ran using HD Tune Pro. I cannot attach the pictures but here are the results.

Transfer Rate Min/Max Average AccessTime BurstRate CPU

Seagate Momentus 26.7/63.6 MB/s 48.7 MB/s 16.3ms 85.7MB/s 5.6%

Western Digital 36.7/84.4 MB/s 61.9 MB/s 14.7ms 107.0MB/s 4.2%


These are the results I garnered with my laptop between the two drives and as you can see from the results the Western Digital Black Scorpio gives a nice boos to the system. My laptop is a Lenovo SL400, 3GB DDR2-800 RAM, Intel Core 2 Duo P8400 2.26GHz 1066FSB, Bluetooth, Fingerprint Reader, Webcam, etc. If you are not able to spend big bucks on a SSD Drives, definitely get the Black Scorpio. It is definitely worth the money and the Free-Fall Sensor doesn't hurt either.
