You might have to make a decision between a Solid Solid State Drive (SSD) or Hard Disk Drive (HDD) as your storage part. So which is better, an SSD or HDD? There is no correct answer to this question because each buyer has different needs and make a decision based on preferences and budget. But the simple tip to you is that if performance and fast bootup is your top consideration and money follows it, SSD is always recommended.
If you are not familiar with SSDs, welcome read our article for beginners first : How to select an SSD?
Durability: HDDs are better than SSDs
Failure rate: SSDs are better than HDDs
In my experience, SSD's failure rate is much lower than HDD's. Theoretically, because the former has limiting number of writing, they are supposed to have higher failure rate. However, in fact its failure rate is lower than HDD's.
An SSD has no moving head, so it is more likely to protect your data safely even in the situation that your hardware is somewhat shaken. On the other hand, most HDDs rest their read and write heads when the system is off, but they are flying over the drive platter during the operation. If you are harsh on your hardware, an SSD is strongly recommended.
SSDs are more expensive than HDDs in terms of dollar per gigabyte. A 4 TB internal 2.5-inch HDDs hard drive costs between $120 and $160 while an SSD of the same capacity starts at $200. That translates into 3 to 4 cents per gigabyte for the HDD and 20 cents per gigabyte for the SSD. Although the price of SSDs has been falling, the price advantage of HDDs is still strong because of well-established technology.
An HDD capacity can be up to 10 TB, whereas an SSD has limited storage capacity (for consumers it goes up to 4TB and for enterprises it runs as high as 60TB.) Even though consumer SSDs top out at 4TB, those are still unusual and unaffordable. An avid computer gamer will require more SSD storage capacity, with 1TB to 4TB drives common in high-end system.
A computer with an SSD will often boot in just a few seconds. The SSD depends on controller technology, which mainly determines its speed, to execute various operations related to reading and writing data. In contrast, a HDD requires time to accelerate to operating specs and is usually slower than an SSD during normal use.
HDDs are more influential in budget and older systems, but SSDs are becoming more prosperous in recently released high-end computers like Apple. PCs and cheaper laptops are expected to continue to offer HDDs for the next few years.
Even the quietest HDD makes a little bit of sound when it spins the drive or its read lead is moving. Faster HDDs will create more noise than that are slower. However, SSDs are literally quiet since they are non-mechanical.
An SSD does not consume electricity spinning up a platter as HDD does. Thus, none of the energy consumed by the SSD is wasted, enabling the drive to run more efficiently.
I used to buy an SSD with 5-year warranty. But now I shift to that with 3-year warranty. I think I have to consider failure rate and repair availability whenever I buy an SSD with 5-year warranty. This consideration tends to take some time and becomes a burden for me...
- SSD: 3-year warranty for home; 5-year warranty for business (10-year warranty in special case).
I used to use an HDD with 5-year warranty. But in the end, I found an HDD with 5-year warranty has a higher failure rate than that with 3-year warranty. Such a big disappointment! So now I am using an HDD with 3-year warranty and the ease of repair.
- HDD: 3-year warranty for home; 5-year warranty for business.

P.S. SSDs have four common malfunctions
The above four malfunctions are terrifying, right? But let me clarify it for you: the first situation is inevitable and possibly happens to any brand. However, the second to the forth case can be prevented only if you avoid those which easily fail.
- BIOS can't detect SSDs
- sometimes a boot sector is missing, but after restarting the computer everything will be fine.
- the screen suddenly becomes frozen
- as soon as the computer is turned on, its screen becomes blue.
