Most people now buy laptops for their computing needs and have to make the decision between getting either a Solid State Drive (SSD) or Hard Disk Drive (HDD) as the storage component.
Before we dive into comparing SSD vs HDD technology, let’s take a quick look at each type of drive.
What’s the difference between the two?
There are advantages and disadvantages to each type of drive, and deciding on which type is right for you comes down to what you use your computer for.
Hard Disk Drive (HDD)
A hard disk drive is the main, and usually largest, data storage hardware device in a computer. The operating system, software titles, and most other files are stored in the hard disk drive.
A traditional hard drive contains a circular disc – known as a platter – that stores your data. The disc spins, allowing the read-write arm to read data on the disc (or write data to it) as it passes.
Inside a hard drive is something that looks more than a bit like an old record player: There’s a platter, or stacked platters, which spin around a central axis — a spindle — typically at about 5,400 to 7,200 revolutions per minute.
A solid-state drive (SSD)
An SSD (solid-state drive) is a type of nonvolatile storage media that stores persistent data on solid-state flash memory.
You’re probably familiar with USB memory sticks – SSD can be thought of as an oversized and more sophisticated version of the humble USB memory stick. Like a memory stick, there are no moving parts to an SSD.
One of the best uses for an SSD in a PC is as a boot drive. This means installing a small-ish capacity drive on which your Windows 10 operating system will live and boot up from every day.
These days you can get a 2TB hard drive for an affordable price, which offers you plenty of space.
In comparison, SSD is expensive, and the cost increases with the increase of per GB/TB.
Any base model of HDD is 500 GB capacity whereas for SSD base model is 128 GB. To Hard drive offers the infinite possibility of magnetic storage on disk.
Storage capacity is an essential criterion to consider when opting to buy an HDD.
The difference between hard drives and solid-state drives is in the technology used to store and retrieve data. HDD utilizes magnetic disk as storage, whereas SSD utilizes memory.
HDDs: As HDDs are the mechanical Drive the flow of data depends on the rpm of the disk. But if we compare with the New latest SSDs the speed of HDDs is very low.
SSDs: As SSDs technology uses electronic interfaces the speed of the SSDs is very very fast as compared to HDD. The Speed is almost 6 times faster than the older HDDs.
Advantages and Disadvantages
|Attribute||SSD (Solid State Drive)||HDD (Hard Disk Drive)|
|Power Draw / Battery Life||Less power draw, averages 2 – 3 watts, resulting in 30+ minute battery boost||More power draw averages 6 – 7 watts and therefore uses more battery|
|Cost||Expensive, roughly $0.20 per gigabyte (based on buying a 1TB drive)||Only around $0.03 per gigabyte, very cheap (buying a 4TB model)|
|Operating System Boot-Time||Around 10-13 seconds average bootup time||Around 30-40 seconds average bootup time|
|Noise||There are no moving parts and as such no sound||Audible clicks and spinning can be heard|
|Vibration||No vibration as there are no moving parts||The spinning of the platters can sometimes result in vibration|
|Heat Produced||Lower power draw and no moving parts so little heat is produced||HDD doesn’t produce much heat, but it will have a measurable amount more heat than an SSD due to moving parts and higher power draw|
|Failure Rate||Meantime between failure rate of 2.0 million hours||Meantime between failure rate of 1.5 million hours|
|File Copy / Write Speed||Generally above 200 MB/s and up to 550 MB/s for cutting edge drives||The range can be anywhere from 50 – 120MB / s|
|Encryption||Full Disk Encryption (FDE) Supported on some models||Full Disk Encryption (FDE) Supported on some models|
|File Opening Speed||Up to 30% faster than HDD||Slower than SSD|
