About this product

Product Information

Upgrade the storage capacity in your computer system with the Western Digital Caviar Blue internal hard drive. This HDD holds 640GB of data, so it leaves you with plenty of space for modern software programs, accessories, and gaming. Having so much extra storage space ensures that there will be room left over after installing your operating system files. The drive can hold hours of video recordings along with countless digital photos and MP3 audio files. Two platters of 320GB each make up the hard drive to offer a durable build and fast data transfer.At 7200 RPM, this WD6400AAKS model hard drive offers fast and reliable access to your data. The 16MB cache gives you fast performance when transferring your data or writing to the drive. You can rely on it to work quickly when uploading or downloading large numbers of files on a regular basis. IntelliSeek technology allows the hard drive to check the right seek speed to minimize noise, energy usage, and vibration. It helps to provide the quietest experience possible while keeping internal temperature low. SoftSeek design makes the read/write functions more efficient, reducing noise level further. Backing up all of your files or transferring them from another system can be done quickly and easily as well.The 640GB Western Digital Caviar Blue drive uses the SATA interface to connect to your computer’s motherboard. Separate screws can be used to install it internally in most desktops. It can be installed on Windows PCs, Mac OS X products, and any other type of computers that accept 3.5-inch SATA drives. The SATA interface supports data transfer speeds of 3 GB/s, making it a fast addition to your desktop. It can also be installed in an external enclosure with USB support instead of being installed as an internal drive. This versatility allows you to remain confident that it will be compatible with almost any modern system.A range of features is included that help make the WD6400AAKS hardware model durable. Data Lifeguard functionality from Western Digital protects against environmental damage and automatically reads the HDD for errors to repair them. Data Lifeguard Tools are software programs that allow you to interact with the hard drive for easy installation and diagnostics. The ShockGuard technology protects it against damage from bumps or movement during operation. NoTouch ramp load construction protects the recording head from wear by keeping it from ever touching the disk media. These user-friendly build elements make maintaining the drive simple and foster support for a longer product lifespan.Western Digital Caviar Blue SATA hard drives have been tested to be used in RAID-0 and RAID-1 applications. They allow data to be stored across multiple hard disk drives for extra file security. This supports a wide variety of consumer and commercial computing uses. Its portable, efficient form factor of 3.5 inches is standard for this product line and will fit into most systems. Backing up and moving the data from your current system to a new one is simple when storing it on this 640GB hard drive.

    Good deal

    Works great. The drive seems to have been used in a server and has a lot of hours on it. Here is some stats about my drive from crystaldiskinfo. (Yours may be different) It has around 110 mb/s read and 110 mb/s write. With it about 90% full, the read and write speeds are about 90-100mb/s.
