HDD vs. SSD

       ok, what is this HDD and SSD all about? Which one is better?. . . Wondering about this questions? this atticle will give the difference between both for better decision making on computer's hard drives.
       first of all, a HDD - Hard Disk Drive is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces.Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile storage, retaining stored data even when powered off.

Hard Disk Drive

while SSD-Solid Slate Drive is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives (HDDs), which permit simple replacements in common applications. SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks, which contain spinning disks and movable read/write heads.Compared with electromechanical disks, SSDs are typically more resistant to physical shock, run silently, and have lower access time and lower latency.However, while the price of SSDs has continued to decline over time (24 cents per gb as of 2017), consumer-grade SSDs are (as of 2017) still roughly four times more expensive per unit of storage than consumer-grade HDDs.

DIFFERENCES BETWEEN HDD AND SSD

       Remember in my last article on How to Make your Computer Work Faster? I did make mention of Install a Solid Slate Drive. because SSDs are faster boating up than HDDs. Nevertheless, HDD have more space and they are cheaper. Do you want a faster computer and you don’t care about the extra cost? or a computer with larger space to store movies, apps and all? knowing the difference between HDD and SSD will help make decision.

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 #62,000 for 512Gig	Only around #32,500 for 2TB HDD
Capacity	Typically, not larger than 1TB for notebook size drives; 4TB max for desktops	Typically, around 500GB and 2TB maximum for notebook size drives; 10TB max for desktops
Operating System Boot Time	Around 10-13 seconds average boot up time	Around 30-40 seconds average boot up 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 draws 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

File Opening Speed               Up to 30% faster than HDD         Slower than SSD

Magnetism Affected?	An SSD is safe from any effects of magnetism	Magnets can erase data

 An HDD might be the right choice if:

• You need lots of storage capacity, up to 10TB 
• Don’t want to spend much money
• Don’t care too much about how fast a computer boots up or opens programs - then get a hard drive (HDD).

An SSD might be the right choice if:

• You are willing to pay for faster performance
• Don’t mind limited storage capacity or can work around that (though consumer SSD now go up to 4TB and enterprise run as high as 60TB)

Thanks for reading. for more info, make sure you stay tune. you can get both HDDs and SSDs at Jumia or Konga.
