Computer technology always has something new to fulfill market’s demand. Besides processor, storage is one part that receives advanced development. At store, you will see the laptop uses two types of storage, HDD and SSD. HDD is hard disk drive as conventional drive to store data and files. It has been around since 1950s. Moreover, SSD is solid state drive as new storage for computer that emerged in late 1970s. You might say that SSD is not new tech, but recent development brings more reliable SSD to the market that shifts laptop and computer production.
Comparison between HDD and SSD
Both have one purpose, which is storage for laptop. Before going further, you need to know both mechanism as it helps to understand the differences. To put in simple explanation, HDD uses spinning disk and platter to do write and read process. When you open it, there is disk similar to CD and DVD. In fact, similar principle is applied in HDD. You can say that HDD is smaller, faster, and better version of DVD.
On the other hand, SSD uses flash memory as similar to USB flash drive. There is no spinning disk, but only flash chip inside SSD. In general, manufacturer produces SSD with similar size to HDD as it needs to fit into HDD plug. However, flash memory inside SSD is very tiny. You can say it is bigger version of USB drive with bigger size and better processing. Therefore, SSD is completely different mechanism from conventional HDD.
1. Processing speed
Which one is faster? SSD is definitely faster than HDD. Study showed than SSD is capable to deliver three to four times faster in term of processing time. It gives better option for new operating system and software to reduce booting time significantly. HDD depends on how fast disk can go. High RMP means faster processing, but not as much as SSD since it uses flash technology.
2. Size and capacity
As it mentioned above, manufacturer can produce SSD with smaller size than HDD. It saves space in motherboard. As the result, laptop becomes thinner and more lightweight. HDD needs space to keep spinning disk at enough position. Even though HDD for laptop is smaller than PC, there is limited size than HDD. For capacity, both have capacity on market. You will find both with capacity 500 GB, 1 TB, 2 TB, and 4 TB.
From mechanism perspective, HDD will have issue for longer utilization. When the reading and writing process is excessive, spinning disk deteriorates slowly until it’s completely broken. SSD still has probability to deteriorate, but it lasts longer twice than HDD. Moreover, HDD produces noise that becomes a signal when it is in lower state.
HDD is cheaper than SSD in term of capacity ratio. With the same capacity, you can get four times cheaper for HDD price. Two laptops with the same processor and specs yet in different storage type may have the same price. However, the storage size is completely different. Until now, SSD is still expensive one but there is development to reduce cost production without losing quality and capacity. As similar to USB flash drive, bigger size starts to be cheaper in next few years.
