Western Digital Scorpio 2.5in 40GB IDE Internal Notebook Hard Drive, 5400RPM, 2MB Cache, Model: WD400UEWD Scorpio delivers best-in-class performance with power requirements comparable to much slower drives. In addition, you'll get the quietest 2.5-inch drive on the market, and the one with ruggedness, reliability, and data-protection features that actively watch over valuable data. This is an OEM drive.Features: Fast: spins at 5400 RPM and delivers seek times of 12ms. It has a standard 2 MB cache, with an 8 MB option. Low Power: spins at 5400 RPM for fast performance but has power specifications similar to slower 4200 RPM drives. Low power consumption yields longer battery life and increased overall reliability. Quiet: features WD's exclusive WhisperDrive technology with SoftSeek algorithms to deliver the quietest 2.5-inch hard drive on the market. Reliable: provides ShockGuard to protect the drive mechanics and delicate platter surface from shocks, both when it's in use and when it's not. This leading-edge technology enables WD drives to meet the highest combined shock tolerance specifications in its class: 250 Gs while in operation, 900 Gs when it's idle. DuraStep Ramp locks the heads off the data disk to provide additional shock protection. Utilizing the most technologically advanced material available on the market, the drive is able to execute a minimum of 600,000 load/unload cycles without contamination – up to twice the performance of its competitors.

Notes: (1) The main concern about the compatibility of a laptop hard drive is the thickness. The most current thickness is 9.5mm. Previously it was 12mm. A thin drive will work as a replacement for a thicker one. However, a thick one, which is no longer available from us, will most likely NOT fit inside a laptop that comes with the thin one. (2) The IDE form factor is virtually the same among all laptop drives on the market. The width of laptop hard drives has been standardized at 2.5". (3) The first and often the most difficult part of upgrading a laptop hard drive is to open the laptop case and gain access to the hard drive. Check our your system manual. If you don't have a manual or yours does not show you how to open the laptop, you'll have to guess where and which screws to open. (4) This OEM hard drives do not come with installation guide or manual. Please use our online hard drive Installation Guidelines and Troubleshooting Tips.(hyz022205) Related Items: | WD Hard Drive | Hard Drives | Laptop Hard Drives | 40GB - 60GB Laptop Hard Drives | Laptop Memory Upgrades | Laptop Batteries | Hard Drives Accessories | WD 60 GB Notebook HD | | ||||||
