sata hard disk or ddr ram best ha is waqt.
Jinti qeemat unti achi cheez

TYPES OF HARD DISKS:
There are a few different types of hard disk but, other than its physical size, the different type of interfaces of the hard disk is the main difference.
Desktop Hard Disk Types: 3.5', IDE and Sata Interfaces
Laptop Hard Disk Types:2.5', 1.8', IDE, Sata, SCSI
Server Hard Disk types:3.5' Sata, SCSI
Types of hard disk interfaces
There are a few ways in which a hard disk can connect/interface with:
(A)dvanced (T)echnology (A)ttachment (Also known as IDE, ATAPI and
- Parallel ATA)
- (S)erial ATA
- SCSI(aka Scuzzy)
There are variants of each interface, and this article will not do justice to the different types of ATA, SATA and SCSI interfaces. Thus, it will only highlight the more common interfaces as used by the home user.
ATA (IDE, ATAPI, PATA)
ATA is a common interface used in many personal computers before the emergence of SATA. It is the least expensive of the interfaces.
Disadvantages
Older ATA adapters will limit transfer rates according to the slower attached device (debatable)
Only ONE device on the ATA cable is able to read/write at one time
Limited standard for cable length (up to 18inches/46cm)
Advantages
Low costs
Large capacity
SATA
SATA is basically an advancement of ATA.
Disadvantages
Slower transfer rates compared to SCSI
Not supported in older systems without the use of additional components
Advantages
Low costs
Large capacity
Faster transfer rates compared to ATA (difference is marginal at times though)
Smaller cables for better heat dissipation
SCSI
SCSI is commonly used in servers, and more in industrial applications than home uses.
Disadvantages
Costs
Not widely supported
Many, many different kinds of SCSI interfaces
SCSI drives have a higher RPM, creating more noise and heat
Advantages:
Faster
Wide range of applications
Better scalability and flexibility in Arrays (RAID)
Backward compatible with older SCSI devices
Better for storing and moving large amounts of data
Tailor made for 24/7 operations
Reliability
Summary:
ATA is the current standard, it uses regular molex power connectors and IDE cables.
SATA is a newer product (also SATA2 is already in development) - it is faster than ATA and uses different cables - much thinner and neater.
Also take into consideration the RPM of the drive, 5400 is a bit slow, 7200 is good, 10,000 is fast but can be quite noisy.
Servers generally use 10k rpm SCSI hard drives, but SCSI is unusual in home computers.
Most motherboards only have IDE connections and so can only take ATA, you would need a new-ish motherboard for SATA hard drives.
The capacity that you need is simply dependant on how much you plan on saving to your hard-drive. Usually from 40GB upwards
