Head to Head: HDD vs SSD

Consumers today are met with a range of storage solutions for their technological device. However you may be wondering what they all mean? What are the advantages and the disadvantages of using different types of memory? Let’s find out.


Hard Disk Drives


HDD’s are the traditional format for storage, they offer large capacities at a relatively cheap price. Essentially it is an nonvolatile solution that contains a large magnetic coated spinning disk. There is a read/write arm that accesses the information stored on the disk while it spins.  The advantage of HDD’s are that they are the cheapest storage solution per GB. HDD’s are known to last a long time (brand dependent) and certain brands are pushing the limits of these Hard drives by filling them up with helium producing 10TB hard drives. Laptops and Desktops commonly come with 1tb hard drives as consumers need larger storage solutions in an increasingly digital world. Unfortunately hard drives are limited in size, the laptop drives being 2.5 inches whereas the desktop drives being 3.5 inches. With laptops slimming down, hard drives are left to go into external storage and hard drives do use up more power compares to flash memory. Manufacturers now place hard drives in their lower tier models and use SSD’s to help slim down the body of the laptops.


Solid State Drives


Solid state drives have been out for a while but never really for the consumer market. It was only a couple years ago when they started to become the normal for consumers. Like HDD’s, SSD’s are a non-volatile solution (meaning they retain your data even with no power) where there are series of interconnected flash memory chips. Think of a multiple USB’s being attached together but are faster and more reliable. There are many different types of SSD’s on the market and the most common size is the 256GB models. Fortunately, SSD’s are becoming cheaper every day with the increasing advances in this technology. Common SSD’s are in a 2.5 inch factor, however recently smaller SSD’s have been produced like the mSATA Mini PCIe SSD card, M.2 SSD in SATA and PCIe variants. Seagate recently released a SSD with a 60tb capacity, however consumer variants go up to 4tb. SSD’s are much faster than hard drives as they do not have any moving parts, which also means SSD’s are hell of a lot more durable compared to HDD’s. Couple years ago, my mate dropped a basketball on a HDD (that was on carpet) by accident and then the HDD just died. However, SSD’s have a lower length in life due to the constant read and writes, but each generation is getter better at preserving life in the memory chips.



I would recommend having both. HDD for all your documents, videos and other unnecessary stuff and keep your operating software on the SSD. This ensures that your computer will boot fast aswell with applications on the SSD. However if you are to decide between an SSD and HDD on a laptop, get the SSD and buy an external hard disk drive.
