Buying hard drives online

Shopping for a hard drive online isn’t as difficult as it seems, however, when going about the business of buying a hard drive, it is very important to take a few figures into consideration. First, we must discern what type of hard drive we are going to need. There are internal and external drives, as well as desktop and laptop varieties available. After you’ve determined what type you need, you must then determine the proper connection. In most cases, the current standard is SATA, or serial advanced technology attachment. There are two versions on the market at present, SATA 1.5 and SATA 3.0. SATA 1.5 has a maximum data transfer rate of up to 150MBs per second; SATA 3.0’s maximum data transfer rate is up to 300MBs per second. If you are looking for something compatible with older systems, go for IDE, or integrated drive electronics.

The maximum data transfer rate is capable of 133MBs per second. However, if you’re looking for hard drives for a server, then SCSI would be the most likely choice. SCSI, or small computer interface system, has a varying range of data transfer rates. From Narrow SCSI to Ultra SCSI, whatever enterprise storage needs one may have, there will be an answer. Next, the price you would like to spend is determined, along with the capacity. It should be noted that the storage size listed is not what you will end up with, it is a general estimate. This is because the loss is due to the formatting process.

Currently, the common size of hard drives on the market range from 500-800GB. It is a good practice to make a list of hard drives that you are considering at this point. When you’ve narrowed it down a bit, now it’s time to choose the appropriate hard drive out of your candidate list. Optimally, something with a high cache size, low average latency, and appropriate RPM speed are ideal. Cache refers to computer memory that devotes itself to rapid retrieval of recent or frequently consulted data. Latency involves the delay in the data retrieval, so the lower the better. While RPM means rotations per minute, a quicker RPM means that it will be accelerated with data reading and performance-wise, but a higher RPM also means more noise.

Furthermore, once you’ve got your final contestants, it is important to research the brand and model via product reviews on such a site as CNET and by consulting hardware charts at Tom’s Hardware, or similar sites. Also, most computer hardware sites have the ability to compare products; it’s helpful to see the figures side by side before you make an executive decision. It is important to know that when you buy a product, it may be OEM- which refers to “original equipment manufacturer”. This means that when you order it, you will not likely receive the accessories or drivers that come with it in the retail box. When you order a hard drive that’s retail, it comes in the box and with all the instructions, extras, and warranty.

Desktop Computer Basics

When purchasing a computer it assists to know some fundamental info about elements and processes. Hopefully these explanations will provide you with a greater understanding of how a personal computer functions, and enable you to ask the salesman some productive concerns.

CPU

The CPU or central processing unit, basicly the CPU interprets instructions and processes data generated by computer programs. The CPU is typically seen as the 'brain' of the computer. The central processing unit controls other components.

Motherboard

The motherboard is typically refered to as the mainboard, program board or mobo. The motherboard could be the main circuit board, Most components (CPU, Memory, Graphics cards, Sound cards, Tough drives, Optical devices, Network cards etc..) are attached to the motherboard. Either by cables or by plugging directly into the motherboard slots. Mainboards are available in a range of sizes, or factor types, on the other hand essentially the most popular is ATX.

RAM

RAM or Random Access Memory describes storage formats and equipment that let information to become accessed in any order (random), not just sequence. RAM may be believed of because the 'working space' of one's laptop or computer. Usually memory is cleared when the laptop is shut down or reset.

Hard Drive

Hard drives enable the storage of information on the laptop. They are generally observed in two formats IDE (Integrated Drive Electronics) or SATA (Serial Advanced Technologies Attachment). Very difficult Drives utilise magnetism to read and write data. A challenging disk utilizes rotating 'platters' or disks which are created up of millions of 'bits'. These 'bits' may be aligned in two directions, 1 direction is assigned '0' the other '1'. Data is stored in binary code by exerting a magnetic force on every single bit, causing it to align inside the desired worth.

Graphics Card

The Graphics card or Video card delivers, as the name suggests, the video output from your pc. Some less expensive motherboards, refered to as "All-in-One" Motherboards have onboard graphics. Even so these are very low end graphics solutions, and will only be beneficial for all those not wishing to do something but simple word proccessing, world wide web browsing and perform. For all those that use their laptop to play games a seperate video card can be a should.

Sound Card

Sound cards provide the audio output for the computer. Almost all motherboards come with an onboard sound module currently, which for many folks will be extra than enough. Nonetheless seperate sound cards is usually bought for those seeking higher top quality, far more feature wealthy audio.

Optical Drives

Optical drives (DVD/CD readers and writers) are related to standard CD or DVD players. They utilise the identical technology to perform the identical tasks because the conventional devices, only created to function in computer systems.

i have a serial ata motherboard and an extra parallel harddrive..lookin for a way to connect them?

the hard drive was a storage unit on an old comp....i want to be able to hook up the ide to the sata on my motherboard...any links or ideas would be appreciated
i have checked many sites and i am frustrated from the endless babble...i know that sata and ide are two compltely different setups but there must be a way...any ideas, links or any suggestions would be appreciated

These are the two possibilities I would recommend (there are others; they are less practical):

1. Buy a PCI IDE card and install it in your machine, and connect your IDE drive to one of the IDE ports on the card. My favourite is the Promise Ultra133 TX2. Be sure you use the latest driver from Promise's web site. This is the most inexpensive option.

2. Buy a kit that will let you turn your IDE hard drive into a USB 2.0 external hard drive. It's easy to install, provided you follow the supplied instructions (for example, many such kits *insist* the IDE drive's jumper be set to the Master position).
