Here what you need to know the difference between SSD vs HDD


AspectSSDHDD
TechnologyNAND-based flash memorySpinning magnetic disks (platters)
SpeedMuch faster, almost instant data accessSlower, measured in milliseconds for data access
Data Access TimesTypically less than 0.1 millisecondsMeasured in milliseconds
Random Read/Write SpeedVery high, measured in IOPS (Input/Output Operations Per Second)Slower, lower IOPS compared to SSDs
Sequential Read/Write SpeedFast, measured in gigabytes per second (GB/s)Slower, measured in megabytes per second (MB/s)
DurabilityMore durable, resistant to shocks and vibrationsSensitive to physical shocks and drops
ReliabilityGenerally more reliable, fewer components that can failMechanical components can wear out over time
Noise and HeatSilent operation, minimal heat generationCan produce noise due to spinning platters and generate more heat
Power ConsumptionConsumes less power, better for battery lifeConsumes more power, may lead to higher electricity bills
PriceHistorically more expensive per gigabyteGenerally cheaper per gigabyte
CapacityAvailable in various capacities, smaller sizes for laptops and larger sizes for desktopsOffers larger storage capacities, multi-terabyte drives common
Use CasesIdeal for speed-critical tasks like operating systems, applications, and frequently accessed dataSuitable for mass storage, archiving, and backup where capacity is key
Form FactorsAvailable in standard 2.5-inch and M.2 form factors, suitable for laptops and desktopsTypically available in 3.5-inch and 2.5-inch form factors
LifespanLimited write cycles but can last several years under typical usageMechanical wear can reduce lifespan in heavy-use scenarios
WeightLightweight due to absence of moving partsHeavier due to mechanical components
Encryption SupportOften includes hardware encryption supportEncryption support varies by model
Shock ResistanceResistant to shocks and vibrations, ideal for portable devicesSensitive to physical shocks, not recommended for portable devices
