Buying a laptop? Want to update the old from the new hard drive? Besides hard disk space to store the size of applications, documents, music, movies and other data, you must also pay attention to their speed performance. If you have fast access to data stored on the hard drive of your laptop, you should buy hard drives with SATA interface, higher speed and larger size of the cache buffer.
Buy Laptop with SATA drives
Serial ATA (SATA)consume less energy, thus saving the battery of your laptop. enchase But their performance speed of your laptop. Most hard drives usually support ATA/66 (66 MB / sec), Ultra ATA/100 (100 MB / sec) or SATA (150 Mbps) interfaces. The figures refer to the maximum burst rate at which the drive can pass data to the system (66, 100 or 150 megabytes per second). SATA transmit data in a series (flow only) to PATA or Parallel ATA which is commonly referred to as a contrast IDEHard disk.
Check the hard disk rotation speed
Remember to check the hard disk does not speed!
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 performance drives. A 7200 RPM drive is faster than a 5400 rpm or 4200 rpm and offers better performance.
Cache buffer size greater - best performance
Size of the buffer cache is a temporary storage area used to improvePerformance of the drive. When the computer calls for data from hard disk if the data in the cache, there is a performance directly to the speed of the cache are related. buffer size larger cache generally means better disk performance. size of the buffer cache laptop hard drive is usually 2 MB, 4 MB or 8 MB.
