Should I replace my hard drive for an SSD? Upgrading to an SSD will revive your old PC or laptop and give it a new lease of life. Just from the increase in boot time alone you will be loving your new SSD.
Not only that SSDs are more reliable, durable, quieter and greener than HDDs.
Will the SSD be as loud as my HDD?
Standard hard drives have moving parts in side them and will measure anywhere between 24 and 36 dBA depending on the data that they are processing.
As SSD's have no moving parts they are effectively silent both when they're idle and under load.
Should I be worried about compatibility when replacing my traditional SATA hard drive with a SSD SATA drive?
No. Any standard SATA based SSD will normally work with any SATA based socket.
Will I save battery life using an SSD instead of traditional HDD?
Yes, the power consumption of an SSD is a fraction of that of a normal hard disk this in one part again is due to the lack of moving parts but also the speed at which data can be accessed.
