Laptop Hard Drives
How to Choose Your Laptop Hard Drives
By Andreas Lee
When purchasing a laptop, you should consider laptop hard drives type rather than just pay attention on laptop specs. Have you ever felt while using the laptop, your laptop battery ran out of power very quickly especially when using lots of software or playing game for a long time, although you have selected a laptop which has long time use battery. Maybe when you bought the laptop, you didn’t pay attention on laptop hard drives type, SATA (ATA) drive or IDE drive.
Laptop hard drives SATA save your laptop battery power more, even if revolutions per minute (rpm) and the buffer cache size on some SATA drives are the same as the IDE drives specs. Based on my observations, even though laptop hard drives SATA have the same specifications with IDE drive but the performance of SATA drive is still faster.
Here I describe the specification which must be considered when choosing laptop hard drives:
Capacity
The data storage capacity in laptop hard drives. The larger the data storage capacity, the better the specification. I recommend choosing the large capacity laptop hard drives, since it can be data backup storage, and for the future in case you need more data storage.
Revolutions per second (RPM, r/m)
The number of disk component rotation in 1 minute. The greater the capacity, the greater the rpm. It’s better to choose 7200 rpm laptop hard drives for best performance.
Buffer cache size
Buffer cache is a temporary storage for files that have been used or read. The larger buffer cache size, the greater storage capacity, and the faster accessing back previously used files. Therefore choose the best buffer cache size if you want a laptop hard drives with the best specs.
If you already have a laptop and want to replace your laptop hard drive with a new one, make sure it is compatible with your laptop motherboard. I always remind you about this, because if you’ve already bought a laptop hard drive, usually you can not change with another hard drive if your laptop motherboard is not compatible.
