HDD vs. SSD Price:
On this case low-capacity, SSDs can be affordable in the 32GB to 64GB range. However, high-capacity SSDs are very costly, especially when measured against cost per gigabyte. On another hand, HDD provides the lowest price per gigabyte. SSD provide a price per gigabyte that is simply barely higher than HDD. Though, HDD is available comparatively low cost.
Let’s compare the average price of hard drives per gigabyte at the time of writing:
Solid State Drive: Hard Disk Drive: | Price per GB US$0.80 per GB US$0.04 per GB |
Even with SSD prices free-falling in recent years, solid state drives will still cost you a massive 20 times plus when compared to hard disk drives of comparable capacities.
SSD vs. HDD Power Consumption
While hard drives aren’t the most important power hogs in your PC (that honor belongs to the CPU and graphics card), nobody can complain about saving additional power.
Solid State Drives Hard Disk Drives | Idle Power Consumption 0.1 to 0.6W 4.0 to 6.0W | Max Power Consumption 2.0 to 4.0W 6.5 to 9.0W |
For this HDD vs. SSD matchup, solid state drives appear because the clear winners.
- By upgrading to solid state drives, laptop users will get to reap many solid benefits – Longer battery life, large performance gains and improved durability (SSDs are capable of withstanding drops and knocks better as they do not have moving components).
- For desktop users, there are also real power savings to be had should you make the change to an SSD. Whereas some people feel that a power savings of 4+ Watts are somewhat unimportant, others will argue that every Watt counts in a world of rising electricity rate.
Storage will not affect battery life in a laptop by more than about 10%. Processor power and LCD actually run down the battery. However, SSD is probably the most power-efficient, and SSHD is a close second because it could spin down more frequently than an HDD.
WINNER: SSD Solid State Drives
FAILURES:
Failure rates on SSD, HDD, and SSHD technologies has the same amount of failures. But SSHD has benefits because it makes use of each the SSD and HDD portions more efficiently than if they were separate.
PORTABILITY:
SSDs are easy portable. Due to their solid-state design. Without shifting parts, they’ll stand at higher extremes of shock, drop, and temperature.
