What is Hard Disk Drive? What is Solid State Drive? What are the advantages of Solid State Drive over Hard Disk Drive? What are the advantages of Hard Disk Drive over Solid State Drive? Difference between HDD and SSD. This is all today we will be talking about and will share a detailed difference in both of these storage drives.



A hard circle drive (HDD) is an electromechanical data stockpiling device that uses magnetic storage to store and retrieve digital information utilizing at least one inflexible, quickly turning circles (platters) covered with attractive material. The shelves are matched with magnetic heads, generally organized on a moving actuator arm, which read and compose information to the platter surfaces. Data is gotten to in a random-access manner, implying that individual blocks of information can be put away or recovered in any request and not only sequentially. HDDs are a sort of non-unpredictable stockpiling, holding put away data in any event when controlled off.




A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently, usually using flash memory. It is additionally here and there called a solid-state device or a solid-state disk, although SSDs do not have the physical spinning disks and movable read-compose heads utilized by conventional electromechanical storage such as hard drives (“HDD”) or floppy circles.


Battery LifeMore power draw, midpoints 6–7 watts and along these lines utilizes more batteryLess control draw, midpoints 2–3 watts, bringing about 30+ minute battery help
CostJust around $0.03 per gigabyte, modest (purchasing a 4TB model)Costly, generally $0.20-$0.30 per gigabyte (in light of purchasing a 1TB drive)
LimitNormally around 500GB and 2TB most extreme for note pad size drives; 10TB max for work areasNormally not bigger than 1TB for scratch pad size drives; 4TB for work areas
Working System Boot TimeAround 30-40 seconds normal bootup timeAround 8-13 seconds normal bootup time
NoiseDiscernible snaps and turning platters can be heardThere are no moving parts, henceforth no stable
VibrationThe turning of the platters can some of the time bring about vibrationNo vibration as there are no moving parts
Warmth ProducedHDD doesn't create a lot of warmth, yet it will have a quantifiable sum more warmth than a SSD because of moving parts and higher power drawLower control draw and no moving parts so little warmth is created
Disappointment RateMean time between disappointment pace of 1.5 million hoursMean time between disappointment pace of 2.0 million hours
Record Copy/Write SpeedThe range can be somewhere in the range of 50–120MB/sBy and large over 200 MB/s and up to 550 MB/s for forefront drives
EncryptionFull Disk Encryption (FDE) Supported on certain modelsFull Disk Encryption (FDE) Supported on certain models
Record Opening SpeedMore slow than SSDUp to 30{4c8208f40a3bfb7c707da805487d02877323e3f237411057a481ffa403c1a164} quicker than HDD
Influenced by MagnetismMagnets can eradicate informationA SSD is sheltered from any impacts of attraction
ToughnessPowerless against physical shocks and developmentNot powerless against shocks and vibration



  1. SSDs don’t get influenced by fracture by any stretch of the imagination, while it’s the worst thing about HDDs – so the more you utilize the drive, the less fast it becomes (while with SSD it doesn’t make a difference how divided – it’s as yet a similar speed). Utilizing some document frameworks like EXT4/BTRFS/and so forth lightens discontinuity, let’s be honest most still use fracture inclined record frameworks like FAT/NTFS – express profound gratitude to Microsoft for that.
  2. Drop an SSD on the floor, and it will work in any casework. Do as such to an HDD, and every one of your information is lost as will the drive be futile.
  3. An SSD can without much of a stretch be a lot littler in physical size than an HDD, particularly on the off chance that you think about the same limits. The main explanation some more seasoned SSDs are a similar size as the HDD they’re supplanting is because they have to get mounted into the same opening – the more significant part of the space inside is simply air. Be that as it may, with things like M2 mounts, you can see all they should be is a card (around the size of a charge card).
  4. The SSDs will, in general, utilize not exactly a 1/10 th of the power that an HDD does, so stuff like battery life gets broadened. On the off chance that you go with an efficient HDD like a WD Green, you at that point free significantly more speed, and for the most part, additionally bargain on strength, life span, and sound age.
  5. Because of less moving parts and no mechanical at all, there is no contact – for example, one less wellspring of warmth.
  6. SSDs are quiet, while HDDs consistently produce vibrations, engines turning up, and in any event, scratching sounds.


The primary advantage HDD has over SSD is cost – on the off chance that you look at comparable limits. For example, a 1TB HDD will, in general, be less expensive than a 1TB SSD. If you analyze against things like futures, at that point the evaluating is a lot nearer – for example, a server-grade HDD is about a similar expense as an SSD of the same limit.
