a high performace harddrive will have 10,000 RPMs and about 320 gigs of sace. After that is goes 7,200, 5,000 RPM's and anywhee from 1 gig too 2 TB
Replacing the hard drive with a SSD (Solid state drive) would improve performance.
An SAS hard drive has many high performance advantages over a SATA drive. The main thing that makes it better is the speed. A typical SATA drive operates at 7200 RPM, yet a typical SAS drive operates at 10,000 or 15,000 RPM.
The external raid is used as a portable high-performance dual-drive storage system. This is used to store highly sensitive data on an external hard drive.
Do a Defrag. and a Disc clean-up
Defragment your hard drive. Be careful though...
A larger hard drive will increase the overall speed and performance of your computer.
Installing a second hard drive in your system will have an immediate impact on system performance if your system is memeory bound?
The three most notable things that hard drive performance will effect is:The start up time of your computer. As the information need to run the OS must be transferred from the hard drive to the systems RAM.The start up time of programs.If you are using almost all of your RAM space the system will use your hard drive to store information normally keep in RAM. In this case your hard drive performance will effect your entire system, but more ram will correct this problem better then a faster hard drive.
S.M.A.R.T. System
Hard drives can make a big difference in computer performance. Consider a solid-state drive if you need quick drive access.
