What Is SSD?

Chances are that the next time you go to buy a laptop you will have the option of a standard mechanical hard drive or SSD. On the surface, the numbers seem to prefer mechanical drives. Even the cheapest computers tend to pack at least 320GB of drive while the SSD option is usually less than 256GB and often very small. 


This is what you will see on the sticker in the store but understanding what SSD is and why they are common in the consumer computer market can help you make an informed buying decision rather than just looking at the right storage. Numbers.


SSDs represent solid-state drives and unlike traditional mechanical hard disk drives, they are not a bunch of LP-style turntables and read heads instead of reducing all that load that goes into a bunch of microchips. 


Why would that be a good thing? Well for starters this is a great way to get more out of shock and shock. Drop or bump into a working laptop while the reading head is spinning and you may lose data or crash the machine; Without moving parts in pc this is not a real problem for SSD. 


The lack of moving parts also makes most modern SSDs extremely fast leading to extremely fast operating times but also improving application performance in cases where the pc application can benefit from the writing structure of SSD; Not every application can.


No moving parts mean even without dizziness noises and reduced heat footprint which leads to less rotating fans and even less operating noises in operation. An SSD-based notebook at the time of this writing will still not be quiet but will usually be much quieter than a mechanical hard-drive-based notebook. 


All of this can also make SSDs more energy efficient which for a laptop should be worth a longer battery life. Finally, the lack of moving parts and dependence on chips rather than plates makes it possible to design smaller SSDs than traditional hard drives although to date most installable SSD manufacturers have opted for traditional hard drive sizes to make them easier to fit. 


So what's the downside? As mentioned the price per gigabyte for an SSD is still much higher than for mechanical drives so SSD options usually invite a price increase or a decrease in storage and usually both. There is some concern about the life cycles of SSDs compared to their mechanical counterparts although it would be wise to back up all your data anyway; Any drive can fail and it's really just a matter of when.


There has been a huge drop in SSD drive prices in the last two years just as the storage capacity of those drives has gone up which is exactly why they are becoming a more common option in laptops. 


It's worth considering the SSD option if the right computer to follow should be thin light and fast but at the moment anyone who needs large media libraries or mostly uses a notebook as a desktop replacement is probably still served a little better with the traditional mechanical type.
