HDDs or hard disk drives in Hong Kong are essential components in computers that store your data permanently. They are used for saving and retrieving digital information that will be needed in the future. The first generation of hard disk drives was introduced by IBM in 1956, making the company the leading manufacturer of HDDs in the market.
Like most electronic devices, HDDs undergo a lot of technological advancements through the years. Their size, capacity, shape, structure, performance, and interface have changed over time. Despite these changes, HDDs are still here to stay and have their niche on the market. Currently, there are four variants of HDDs, each has its own pros and cons.
Parallel Advanced Technology Attachment (PATA)
Formerly known as Integrated Drive Electronics (IDE), this variant of hard disk drives is the first one to harness the PATA interface to connect to computers. It’s one of the most common drive interfaces for connecting hard drives and other devices to computers. PATA drives have a data transfer rate of up to 133 megabytes per second with a maximum of 2 devices that can be attached to a drive channel. These drives use 40 or 80 wire ribbon cable to transfer bits of data simultaneously. They store data through the use of magnetism and their internal components are made from mechanical moving parts. Today, most hard disk drive manufacturers harness SATA (Serial ATA) as it performs much better compared to PATA. If you have devices that house PATA drives, then it’s best to upgrade them.
Serial ATA (SATA)
This replaced the PATA drives found in computers like desktops and laptops. Although PATA and SATA drives connect the same way to a computer, they each have a unique interface. When it comes to performance, SATA drives are more powerful and faster compared to PATA. Here are a number of advantages of SATA drives.
- SATA drives allow faster data transfer than PATA variants through the use of serial signaling
- SATA cords are thinner and far more flexible than PATA cords.
- They sport a 7-pin data connection with a cord limit of 1 meter.
- The disks that are integrated into the SATA drives do not share bandwidth since they only allow one disk drive for each controller chip on the motherboard.
- They use up less power, requiring only 250 mV compared to the 5 V for PATA.
Small Computer System Interface (SCSI)
This type of hard disk drives makes use of the Small Computer System Interface that is fast and reliable. It is rare in computers and is typically integrated into expensive storage systems. They can also be found in video editing system where maximum throughput is required.
Other advantages of SCSI drives include better scalability and flexibility. They can also store and move a large amount of data with no issues. Plus, they are tough drives that can endure 24/7 operations.
Solid State Drives (SSD)
They are the latest variants in drive technology. They are totally different from others in a way that they don’t house moving parts. Not to mention, they do not save data using magnetism, instead, they harness flash memory technology. This speeds up data storage and access, making solid state drives useful in portable computing. Also, they harness integrated circuits or semiconductor devices to save data permanently. Aside from faster data access, SSD drives are less vulnerable to shock, have lower access times and latency, are durable, and use less power.
How to Select a Hard Disk Drive
Figure out the type of disk drive found in your PC
The first thing you need to do is find out the type of disk drive found in your PC mainboard. Most PC mainboards these days support both PATA and SATA drives. If your computer’s mainboard can support these drives, then go for a SATA disk drive. However, if you don’t want to break your piggy bank, a PATA disk drive is the most suitable option.
Choose PATA drives if your computer is quite old
PATA drives in Hong Kong are backward compatible, making them usable for your old computer. They work without any issues, however, they run at a lower performance level compared to other advanced models. Also, before you buy a PATA drive, make sure you read your mainboard manual and know your computer’s operating system. Keep in mind that older operating systems cannot operate with disk drives that have a storage larger than 40 GB.
Consider your budget
The size or capacity of the disk drive depends on your budget. It is also dependent upon the type of work you will be doing on your computer. If it is for saving your music collection, videos, and photos, then go for a 300 GB hard disk drive. If it is for typical work use, then a hard disk of 80 to 160 GB will be an ideal choice.
