How To Buy An External Hard Drive
Have you just started looking for a hard drive
?The chances are that you might be having a little difficulty doing this because you have concerns over the size and the price but you can't work out exactly what you need.
How many times have you heard this phrase: Computers are all the same these days, just buy the cheapest one? Well unfortunately that is not the case; you need to be very careful in choosing a hard drive that gives you the only sufficient on which to store your data, but also one that will be reliable in the long term. After all, when you are in data recovery mode, the last thing you need is a hard drive failure.
Let's look at a couple of factors you will need to bear in mind when choosing the most suitable hard drive for your needs.
Determine the exact amount of data storage you will need. To do this you simply need to check the existing data you have stored on your computer's hard drive and make a note of the total memory used. You will then need to consider how much extra data you will be creating over the foreseeable future and add this amount to your existing figure. External hard drives come in a variety of sizes but it is not always a case of the biggest is best. External hard drives for home use usually start at 500 GB but there are many models which can store 4 TB. An external USB will hold up to 100 MB, and may be suitable for small backup needs.
Whilst it is possible to back up your data onto a CD or DVD, these discs have minimal capacity, usually a maximum of 4 1/2 GB. External hard drives will give you a lot more flexibility by allowing you to perform a backup with a USB connection, a quick and easy solution to your backup needs. CDs and DVDs deteriorate over time, so for long-term storage they are not the best option.
If portability is important, then you will have plenty to choose from with capacities up to 4 TB. Make sure that these external hard drives come with software to allow you easy access and quick backup utilities.
After you have decided your data requirements, you can now decide how much you are willing to pay. For obvious reasons it is best to stick with well-known brands which your retailer will be able to explain to you. It is best to visit several retailers and choose one that is consistently recommended.
Spindle speed. It is a good idea to buy a hard drive with the fastest spindle speed available. This speed refers to the speed at which the drive rotates with the higher speeds indicating a faster backup process.
Cache size. Try to find the highest rated cache size for an external hard drive as this determines how fast data can be transferred and stored. It refers to transfer process where data being transmitted from one hard drive to the next is held in memory until storage space has been cleared and processed by the receiving hard drive. The larger the cache size, the quicker the transfer.
There are many factors to think about when buying an external hard drive, but if you keep in mind that you are going to be relying on the disk you choose for a possible data file recovery, the cost factor will be put into proper perspective and your choice will become much easier.
