When it comes to selecting an ideal drive for the computer, Solid State Drive (SSD) recently becomes more and more popular. It’s said that SSD is better than traditional Hard Disk Drive (HDD).You may wonder if this is true. Here we will compare the two kinds of drives in 10 aspects for you to pick an ideal one.
Common computer users must be familiar with the traditional spinning hard drive – HDD which plays an important role in computer storage. However, nowadays, Solid State Drive (SSD) has become a new choice for people. “It can speed up the computer performance”, many specialists say. Although SSD has many advantages, it doesn’t mean that SSD is the best choice for you. To select an ideal drive can be a bit complicated. Don’t worry, we will tell you the differences between SSD and HDD to help you with the task.
The solid-state hard disk capacity is generally between 64GB-512GB. But the conventional mechanical hard disks have larger capacity that is between 500GB-4TB. Thus if you have a large demand in capacity, then HDD is a better choice for you.
Since HDDs have moving parts like read/write heads, if you shake the drive violently, it tends to be corrupt easily. But on the contrary, SSDs have no moving parts at all, so it can safeguard your data in many accidents like shaking, falling off or even earthquakes.
Although SSDs capture larger share of a market in recent new laptops, HDDs are still dominate the market due to older systems and low budget.
SSDs offer better read/write speeds than HDDs. It can express in many conditions. For instance, a computer equipped with SSD will boot faster and launch apps faster than the other ones which are equipped with HDD.
As HDDs have spinning disks and moving read heads, even the best drive will have little noises. But SSDs have no noises at all, because they don’t have any moving parts and are non-mechanical.
Similar to the foresaid case, SSDs with no moving parts are much cooler than HDDS when running.
Dealing with Vibration
Research shows SSDs can better withstand the vibration than HDDs due to no moving parts. It is believed that SSDs can withstand 10 times more vibration than HDDs.
Although SSDs get many advantages owing to its non-mechanical feature, it cannot offer data recovery after the deletion. But data in HDDs can be restored by apps or specialists. For instance, if you delete an important email in Outlook, and you want to attempt an Outlook recovery to retrieve the email, you can either resort to experts or third party tools.
As hard drives usually use more established technology which is older than SSD’s, they cost much less than SSDs. For example, if a 2TB internal 2.5-inch hard drive costs $100, an SSD of the similar form factor and capacity will cost you more than 5 times.
Apparently, HDDs have a size limit depends on its spinning platters. But SSDs seems to have no such limitation and could be increasingly smaller with the technology developing.
