Solid State Drives vs. Hard Disk Drive: Which one is better?

Since 1960's, Hard Drives giving several advantages to many home and professional user, but sometime become infamous due to its moving parts, head crash and so on. HDD's are believed to wear out overtime and hence, engineers are seeking out ways to make it more compatible, durable & free from failure. They gave a perfect substitute of any hard drive which nearly sorts the various bogus hard drive problems, popularly known as SSD (Solid State Drive).

Solid State Drives

As everything in this real world has its own pros and cons, so as SSD have too but cases of failing SSD are very few and unlikely to occurs in near future. But let's start from scratch and deeply analyze the benefit of solid drive over hard drives and vice versa, so you could decide the best one for your netbook, laptop, nettop or desktop.

Differentiating Hard drives with Solid state drive:

 Physical Parts

Traditional hard drive contains physical equipments like platters, heads, spindle motor etc. to store data, perform read/write operation and many others. A hard drive uses platters with magnetic coating to store data on hard drive and maintains it even after no power source is connected. Solid state drive operates in same manner but without using any platters, as it has series of flash memory chips for storing data. Now a days, hard drive comes with a huge storing capacity and easily available unlikely any solid drives which is far more slim and free from power failure.

 Storing Technology

Hard drive use to store data in fragments. That means, while saving data, files were scattered in contiguous blocks throughout the sectors and blocks. But Solid state drives are completely different and doesn't needed fragmentation as it's has no physical read heads, which makes it more faster in storing data, launching application etc.


Price are also the decisive factor for which, HDD becomes the winner over SSD. Solid state drives are much more costly than HDD, for ex. You can buy a 1TB of hard drive by spending in between $100 tp $150, but SSD takes 8 times more than the normal hard drive prices of the same storage capacity.


SSD are made up with a series of flash drives instead of any physical equipment. Flash drives are completely different from the one which is used in thumb drives and may store more than 16 times of data in compare to thumb drives.

 Both HDD and SSD are designed to fight well against failure but SSD can operate more efficiently in harsher environment without failing where HDD does fails. Since most HDD's are fail while doing read operation, rather than SDD which often fails during write operation. Your data is more likely to corrupt due to fail read operation, so we can say that SSD's are very rare cases of failure in compare to HDD's.

 Capacity: As with growing storing needs, normal user demands up to 250 GB to 1 TB of hard drive but SSD's are less likely to fill that gap right away. The maximum storage capacity of recently launched SSD of 128 GB which didn't seems to fulfill the current storing needs and once again HDD's shines at the top.

 Speed: This is where SSD's become the first choice among users who wants to make their PC even faster. SSD's are significantly fast in booting Windows, transferring files, launching application etc.


Since, SSD's are still in its development phase, they are hardly available in the market. Moreover, there is no chance to get any more eventful news until 2014 as flood effected the hard drive markets in Thailand (Major Production Center).Whereas, hard drives can be easily available and can be distributed whenever you want.


It's all up to you to choose the one which best suites to your pocket, energy and data security. HDD's can be preferred if money, capacity and availability are your primary concern but SSD's could be best if you are looking for a hard drive having a great reliability, raggedness or didn't need fragmentation etc.

Since SSD's can be used for Windows & MAC both, it provides the equal benefit to both platform user and soon gets the popularity what it deserves.

I would go with solid state drive, is that OK? I know they are much expensive.
