Internal or external: when it comes to mass storage, there is a fundamental distinction between SSD and HDD hard drives. But where exactly are the differences and what are the respective advantages and disadvantages? We explain.
SSD: Less Susceptible to Mechanical Defects
The biggest difference between HDDs and SSDs is their construction. While the HDD (Hard Disk Drive) contains a read/write head, the SSD (Solid State Drive) consists of multiple flash memory chips. Since there are no moving parts, SSDs usually survive drops without any problems. With an HDD, however, a head crash (read head touching the magnetic platter) can quickly occur, resulting in data loss. Typical signs include clicking or clacking noises.
SSDs are significantly more expensive than HDDs. For comparison: a 500 GB SSD costs approximately 400 euros. With an HDD, you get four times the storage capacity for a quarter of the price (2,000 GB for 100 euros).
HDD: Better Chances for Data Recovery
An HDD consists of one or more rotating magnetic platters and a read/write head. Naturally, these moving parts are more susceptible to wear and external influences (heat, dust, moisture, vibrations). In the worst case, however, data recovery attempts are more promising than with a comparable SSD.
SSD: Winner in Terms of Speed
Desktop computers and notebooks with an SSD start approximately twice as fast as systems with an HDD. Programs stored on the SSD load up to four times faster. Additionally, SSDs operate silently. An HDD in a slim laptop case, on the other hand, can be quite noisy.
The individual memory cells of SSDs can only be written to a limited number of times. Their lifespan is therefore significantly limited.
HDD: Significantly More Storage Space
If you value large storage capacity, you cannot avoid an HDD. While HDDs offer up to 8 TB, SSDs max out at 2 TB - at least with current models.
SSHD as an Alternative
If you cannot quite decide which advantages and disadvantages of SSDs and HDDs outweigh the others, you can choose an SSHD. This hybrid solution combines the advantages of SSDs with those of HDDs. In terms of price, power consumption, storage space, and longevity, these models are positioned midway between HDDs and SSDs.
