Buying a laptop? Would you like to extend the old with a new hard drive? In addition to the disk space to store applications, documents, music, movies and other data, you should also make sure that their speed. If you want quick access to data stored on the hard disk of the laptop you should buy hard drives with SATA interface, higher speed and larger size of the buffer cache.
Buy Laptop with SATA drives
Serial ATA (SATA) drives consume less current, sosave your laptop battery. But they also enchases speed performance laptop. Most hard drives usually support ATA/66 (66 MB / sec), Ultra ATA/100 (100 MB / sec) or SATA (150 MB / sec) interfaces. The numbers relate to occur at the rate at which the maximum burst data to the system disk (66 megabytes, 100 or 150 per second) can. SATA transmit data in a row (in a single stream) to PATA or Parallel ATA, by contrast, commonly referred to as an IDE hard disk.
Check the hard driveTravel speed
Do not forget to check the speed of the hard drive!
The speed of rotation of the disc tells you how fast the disc spins its disks in revolutions per minute (rpm). A higher speed means higher drive performance. A 7200 rpm is faster than a 5400 rpm or 4200 rpm and offers better performance.
Major Cache Buffer - Best performance
Size of the buffer cache is a temporary memory data can be used to increase drive performance. If your computerrequests for data from the hard disk if the data in the cache, there is an increase in production directly to the speed of the cache together. Increased size of the buffer cache usually results in better hard disk performance. Cache buffer size on most portable hard drives is usually 2 MB, 4 MB or 8 MB.
