Speed Up Laptop or PC


Computer is basically a system unit. It consists of a number of parts. Computers / laptops are not available for speed unless these devices are in sync with one another. Software is also related to it. The issue that we will discuss today is about hardware related issues .A standard computer configuration is dependent on mother board, processor, RAM & Hard Disk. The operating system of computer partly depends on Hard Drive. The normal hard disk we usually use are electro mechanical hard disk. Instead of electro mechanical hard disk , SSD hard disk are available in the market. Let’s know the differences between the SSD Hard disk drive Vs Electro Mechanical Hard disk . When & where, which one to be used.

The traditional spinning hard drive is the basic nonvolatile storage on a computer. That is, information on it doesn’t “go away” when you turn off the system, as is the case with data stored in RAM. A hard drive is essentially a metal platter with a magnetic coating that stores your data, whether weather reports from the last century, a high-definition copy of the Star Wars trilogy, or your digital music collection. A read/write head on an arm accesses the data while the platters are spinning.
A History of HDDs and SSDs


Hard drive technology is relatively ancient (in terms of computer history, anyway). There are well-known pictures of the infamous IBM 350 RAMAC hard drive from 1956 that used 50 24-inch-wide platters to hold a whopping 3.75MB of storage space. This, of course, is the size of an average 128Kbps MP3 file today, in the physical space that could hold two commercial refrigerators. The RAMAC 350 was only limited to government and industrial uses, and was obsolete by 1969. Ain’t progress wonderful? The PC hard drive form factor standardized at 5.25 inches in the early 1980s, with the 3.5-inch desktop-class and 2.5-inch notebook-class drives coming soon thereafter. The internal cable interface has changed from serial to IDE (now frequently called parallel ATA, or PATA) to SCSI to serial ATA (SATA) over the years, but each essentially does the same thing: connect the hard drive to the PC’s motherboard so your data can be processed. Today’s 2.5- and 3.5-inch drives mainly use SATA interfaces (at least on most PCs and Macs), though some high-speed SSDs use the faster PCIe interface instead. Capacities have grown from multiple megabytes to multiple terabytes, more than a million-fold increase. Current 3.5-inch hard drives have capacities as high as 10TB, with 2.5-inch drives maxing out at 5TB.
Advantages and Disadvantages


Both SSDs and hard drives do the same job: They boot your system, and store your applications and personal files. But each type of storage has its own unique feature set. How do they differ, and why would you want to get one over the other?
Price: SSDs are more expensive than hard drives in terms of dollar per gigabyte. A 1TB internal 2.5-inch hard drive costs between $40 and $50, but as of this writing, an SSD of the same capacity and form factor starts at $230.

Maximum and Common Capacity: Although SSD units top out at 4TB, those are still rare and expensive. You’re more likely to find 500GB to 1TB units as primary drives in systems. While 500GB is considered a hard drive in 2016, pricing concerns can push that down to 128GB for lower-priced SSD-based systems. Multimedia users will require even more, with 1TB to 6TB drives common in high-end systems. Basically, the more storage capacity, the more stuff you can keep on your PC. Cloud-based (Internet) storage may be good for housing files you plan to share among your phone, tablet, and PC, but local storage is less expensive, and you only have to buy it once.



This is where SSD shine. An SSD-equipped PC will boot in less than a minute, and often in just seconds. A hard drive requires time to speed up to operating specs, and will continue to be slower than an SSD during normal use. A PC or Mac with an SSD boots faster, launches and runs apps faster, and transfers files faster.

Fragmentation: Because of their rotary recording surfaces, hard drives work best with larger files that are laid down in contiguous blocks. That way, the drive head can start and end its read in one continuous motion. When hard drives start to fill up, large files can become scattered around the disk platter, causing the drive to suffer from what’s called fragmentation. While read/write algorithms have improved to the point that the effect is minimized, hard drives can still become fragmented.

SSDs can’t, however, because the lack of a physical read head means data can be stored anywhere. Thus, SSDs are inherently faster.


An SSD has no moving parts, so it is more likely to keep your data safe in the event you drop your laptop bag or your system is shaken about by an earthquake while it’s operating.

Most hard drives park their read/write heads when the system is off, but they are flying over the drive platter at a distance of a few nanometers when they are in operation. Besides, even parking brakes have limits. If you’re rough on your equipment, an SSD is recommended.


Hard drives are more plentiful in budget and older systems, but SSDs are becoming more prevalent in recently released laptops. The product lists from Western Digital, Toshiba, Seagate, Samsung, and Hitachi are still skewed in favor of hard drive models over SSDs. For PCs and Mac desktops, internal hard drives won’t be going away completely, at least for the next couple of years. SSD model lines are growing in number: Witness the number of thin laptops with 64,120,256 to 512GB SSDs installed in place of hard drives.

Form Factors:

Because hard drives rely on spinning platters, there is a limit to how small they can be manufactured. There was an initiative to make smaller 1.8-inch spinning hard drives, but that’s stalled at about 320GB, 5512GB. since the phablet and smartphone manufacturers have settled on flash memory for their primary storage. SSDs have no such limitation, so they can continue to shrink as time goes on.


Electro Mechanical (HDD)Faster hard drives will make more noise,vibration than those that are slower.

SSD Hard Drive make virtually no noise at all, since they’re non-mechanical.

Overall :


Hard drives win on price, capacity, and availability.

SSD Hard Drive:

SSDs work best if speed, ruggedness, form factor, noise, or fragmentation (technically part of speed) are important factors to you.

If it weren’t for the price and capacity issues, SSDs would be the hands-down winner.

The price of SSDs is coming down.

Note: Use SSD hard disk for operating system & use HDD hard disk / external hard drive for media & data storage only.
