What storage sizes are available for internal hard drives?

When faced with the option of various internal hard drives to choose from, the first thing you should check is the storage size of any potential purchase. Ebuyer stocks HDDs in sizes of up to 12 terabytes, which equates to a massive amount of storage space. This size will perhaps only be of interest to enterprise users, or those who work in the creative industries and have a vast amount of data such as large video files to store. But home and small business users should generally look for between 500GB and 2TB, and will find that these are more than adequate to store a large amount of documentation and other files.

Performance of internal hard drives

While the size of the storage is going to be the leading factor in your choice of new internal hard drive, it's likely that performance is also going to be an issue (or at least a consideration). Check out the specifications of the individual hard drive you are interested in, to see what the read / write speed is like, and whether this will integrate seamlessly into your current set-up or new build.

Form factor and Interface of internal hard drives

Other important factors to consider when selecting a new internal hard drive are the form factor and the interface (with the most common for PC owners being 3.5" and SATA lll respectively). In terms of form factor, it is necessary to buy a hard drive which will fit into the existing internal bay if you have decided to replace or upgrade. If it doesn't fit, it won't work! If, on the other hand, you are building a new PC system, then the case that you have chosen will have specifications from which it will be possible to tell which form factor of internal hard drive you need.

There are various form factors available, with 2.5" and 3.5" being the most common. Again, make sure, before you buy, that the hard drive is the correct form factor for your needs. The interface could be SATA (which stands for Serial Advanced Technology Attachment) or, becoming more common, NVME (Nonvolatile Memory Express) which means there is higher input / output per second. The type of interface varies from model to model, so make sure to check which is the correct connection for the motherboard you already have, or for the one you are planning to include in your new system if you are building one.

Internal hard drives for business

Business and professional users will usually require much higher storage capacities than home users, and Ebuyer stocks an extensive range of enterprise solutions for those organisations looking for internal hard drives with a capacity in excess of 1 terabyte. Other sizes available include 2TB, 4TB, 6TB and so on, up to 12TB (which offers a massive amount of storage). The larger the amount of storage then the more documents and files you will be able to store on the hard drive. If you work in design, video production or audio production, then it is advisable to go for a much larger internal hard drive, as the files you will be working with on a daily basis tend to be much larger than the size of 'normal' office-type documents and files.
