Looking for new Hard-drive for your computer? Do you thinks that all Hard-drives are same? It is wrong! There are numbers of technical points which you should keep in your consideration before going to buy hard-drive for your computer.
1.Brand of Hard drive:
The brand of a hard drive can tell you quite a bit. If it’s a company that’s been making drives for quite a while, it’s reasonable to assume that they know what they’re doing. If the company keeps resurfacing with a new name, or if the drive is generic, don’t buy it. Hard drives aren’t exactly simple to build; the firmware alone must be specific to the microinch or the drive could conceivably fail. I always recommend Samsung drives, as they are more dependable than many of the modern manufacturers. Also notable are Maxtor and Western Digital drives; Seagate also makes great, dependable medium, but their entry into the field of data recovery may prove to be a conflict of interest.
2. Size of Hard-drive:
You should count how much data do you want to store on your harddrive if you want to store pictures, movies, or music on, you might want to buy based on size. 100 gigabytes will cover most home user needs, but if you’re storing video, go for something bigger. 200 or 300 gigabytes is the recommended hard drive size for storing uncompressed video; music and picture files are much smaller.
If you buy an internal drive, it will likely cost a lot less than an external drive; remember to make the same basic considerations. With an internal drive, 100 gigabytes will more than last most home users; if you’re using your computer for email, internet, a few games, and some mp3s, 100 gigabytes is more than enough. You might want to consider buying an even smaller drive; no use buying what you don’t need. 40 gigabytes will be fine if you want a computer for basic home use. Business hard drives usually don’t need to be any larger than this, either.
Laptop hard drives can also be generally kept small; 20 gigabytes is standard, 40 gigabytes is usually more than enough. If you need more for movies or music, an upgrade to 60 or 80 gigabytes shouldn’t be too much more expensive.
3.Speed of Hard-drive:
For home and business PCs, the speed of a drive won’t be incredibly important. 7200 RPM (Rotations Per Minute) is recommended; if the RPM’s far slower than that, your drive might not keep up with you. While there is nothing wrong with a faster drive, it’s possible that faster speeds increase the chance of drive failure. Unless you have a specific reason to buy a lightning fast drive, don’t buy based on a drive’s RPM.
4. Connection Type:
Before buying a new hard-drive you need to make sure that the type of connection your hard drive supports corresponds to the type of connection that your computer can use. External drives usually use USB 2.0 or Firewire. If you’re computer only has one of these, don’t buy a drive made for the other. Windows computers usually have USB 2.0, but check your computer’s documentation.
Internal drives usually use either SCSI, SATA, or IDE. No, I’m not just putting random letters together. Each of these connection types are quite different, but for our purposes, we’ll just consider the availability of each.
It’s reasonable to assume that SATA drives will be widely accepted in the following years, so if you can, get one of these. At this time, though, SATA isn’t universal, so you’ll probably need an IDE drive. Most consumer motherboards use IDE; though SCSI is faster, it’s not too common. Again, you’re going to need to look at your computer’s documentation. Make sure that the drive you purchase hasn’t been used. A hard drive that has been in use has an exponentially higher failure rate than a new drive. After all, you don’t even know what they did with it.
