Comparison between SSD and HDD

Attribute	SSD (solid state drive)	HDD (hard disk drive)
Power draw/battery life (Power Consumption/battery life)	Less power draw, averages 2-3 Watts, resulting in 30 + minute battery boost√ (Less power consumption, with an average of 2-3 Watts, resulting in 30-minute battery boost)	More power draw, averages 6-7 Watts and therefore uses more battery (More power consumption, with an average of 6-7 Watts, so more batteries are used)
Cost (Cost)	Expensive, roughly $0.50 per gigabyte (based on buying a 1 TB drive) (Expensive, about $0.50 per gigabyte (based on purchasing a 1 TB hard drive ))	Only around $0.15 per gigabyte, very cheap (buying a 4 TB model)√ (It is only about 0.15 yuan, and gigabyte is very cheap (buy a 4 TB model ))
Capacity (Capacity)	Typically not larger than 512 GB for notebook size drives; 1 TB Max for notebook tops (notebook generally not greater than 512 GB, desktop drive up to 1 Tb)	Typically around 500 GB and 2 TB maximum for notebook size drives; 4 TB Max for every tops√ (The size of the notebook driver is usually between GB and 2 TB, and the maximum size of the desktop driver is 4 TB)
Operating system boot time (Start Time)	Around 22 seconds average bootup time√ (The start time is about 22 seconds on average)	Around 40 seconds average bootup time (The start time is about 40 seconds on average)
Noise (Whether there is noise)	There are no moving parts and as such no sound√ (There are no moving parts, so there is no sound)	Audible clicks and spinning can be heard (Audible click and rotation can be heard)
Vibration (Whether there is vibration)	No vibration as there are no moving parts√ (No vibration, no moving parts)	The spinning of the platters can sometimes result in Vibration (Disk rotation sometimes causes vibration)
Heat Produced (Heat generation)	Lower power draw and no moving parts so little heat is produced√ (Low power consumption, less heat for moving parts)	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 (Hard disks do not generate a large amount of heat, but there will be a measurable number that is hotter than drawing an SSD due to moving parts and high power)
Failure Rate (Failure Rate)	Mean Time between failure rate of 2.0 million hours√ (Average failure rate is about 2000000 hours)	Mean Time between failure rate of 1.5 million hours (the average failure rate is about 1500000 hours)
File copy/write speed (File copy/write speed)	Generally above 200 Mb/s and up to 550 MB/s for cutting edge drives√ (Blade drives are generally at 200 Mb/s and 550 Mb/s)	The range can be anywhere from 50-120 Mbit/s (Range: 50-120 Mb/s)
Encryption (Support for encryption)	Full disk encryption (FDE) supported on some models√ (FDE ))	Full disk encryption (FDE) supported on some models√ (FDE ))
File opening speed (File Reading Speed)	Up to 30% faster than HDD√ (Opening a file is as fast as 30% faster than HDD)	Slower than SSD (Slower than SSD)
Magnetism affected? (Whether friction with magnetic objects has an effect)	An SSD is safe from any effects of magnetism√ (Friction with magnetic objects does not affect data stored on SSD)	Magnets can erase data (Data loss due to friction with magnetic objects)
