Product Information

The Western Digital WD2500AAJB hard drive is the perfect fit for your storage needs. Featuring Whisper Drive technology to reduce noise, the Western Digital Caviar Blue also boasts fantastic drive protection that's based on two different technologies. Engineers from Western Digital designed special firmware subroutines in the onboard hard disk controller to protect data. These subroutines perform read tests each time system software transmits data to a block. When a block on the internal platters fails a test, the information written there is immediately recalled from the buffer and moved to another block. The WD2500AAJB controller board then marks the block as bad based on the results of a second test to prevent data corruption.Logical Block Addressing (LBA) technology is the second portion of the data protection scheme WD2500AAJB drives use. Each block on the platters receives a number that your desktop computer uses to address it. Your operating system will never have to concern itself with disk geometry, meaning that you won't have to worry about a cylinder or sector calculation going wrong. It also uses a special type of intelligent power consumption subroutine to spin down the platters when they're not in use.The astonishing 250GB capacity makes it easy to save and store software as well as your important multimedia files. This Western Digital internal hard drive is also useful for those who need additional hard drive space in coordination with their existing setup. You can install it in an extra bay with a standard ATA100 interface. The included ATA-6 jack gives the WD2500AAJB the ability to get SATA performance out of an IDE class connector.Since it's specifically designed not to stop or stutter, this Western Digital hard drive is great for uses where you wouldn't otherwise be able to maintain your hard drive. If you need to install a disk inside of a game console that has an Ultra IDE interface, then this is a great choice. The 7200RPM spindle speed will act as a warranty against lag when playing online. This high RPM measure is also good if you're looking for something to use with DVR machines. It's compatible with the MFS Tools standard needed by many digital recording systems. If your game console or multimedia device can't access the entire 250GB as one volume, then you can easily install MBR or GUID partition information on this disk. This will allow you to split it into multiple smaller logical drives for your device to work with.Keep in mind this is a full-sized 3.5-inch drive, which means it is ideal for systems that need beefier disks. It's built to support all standard BIOS and UEFI boot systems, so you can use this disk even if you're working without a popular brand of hardware. Gamers who build their own PCs to play intense FPS or MMORPG titles will love the low search times and the large 8MB cache. This drops latency way down, which translates into faster load times for even the most complex graphical programs.
