The difference between SSD and HDD.

Storage for computers

Solid State Drives and Hard Disk Drives

Many people don't know the difference between a Solid State Drive (SSD) and a Hard Drive Disk (HDD). Many people also don't know whether or not to buy one or the other. Allow me to clear things up for you in this article.

Let's just say, small things pack a humongous punch.

Hard Drive Disks

Hard drive disks are a type of storage unit computers use to store user data. Anything from games, to pictures and movies is stored on the hard drive. The way a HDD works is complicated yet simple, anywhere from one to ten moving platters spin at varying speeds below a reading head unit (essentially a big magnetic stick) that can both write data to the disk in the form of 1's and 0's, or read it in the same way.

Looks simple, but actually very complex.
The reason we have deviated from HDD's is because we have developed a faster method of data transportation. You may have heard of USB storage. You stick a thumb drive in your computer and BAM! you've got your files right there. This is almost the same idea behind the Solid State Drives except for being a little less portable. Hard drives have been around for a while. The first hard drive had humongous disks (as big as most computers in modern days) and didn't hold very much information (I believe around 100MB). As we advance storage is getting physically smaller, but bigger in capacity and faster in data transfer.

This is the benchmark of an absolutely outstanding HDD. In fact this configuration may be done in RAID (Multiple HDD's). Although it gets the performance boost from being in RAID it still cannot compete with the raw outputs of the SSD

Solid State Drive

Solid state drives are a relatively new technology that uses SATA 3 (some use lower) to transfer data from a storage unit to a computer and vice versa. Physically, there are absolutely no moving parts in this hardware component. This means SSD's are able to operate and cooler temperatures, consume less power,  and are generally more relaible.

Looks complex, but surprisingly simple.
Solid State Drives, of course, are a lot more expensive per gigabyte compared to Hard Drive Disks. I believe this is the sole reason they aren't fully integrated into the mainstream yet. It is possible to run a SSD and a HDD in tandem, this is actually a very cost-effective way to get a little more performance out of your computer. In terms of gaming, having a SSD will only improve loading times. However, it improves loading times by a very noticeable amount. It is indeed possible to configure RAID settings with SSD's.

Although memory storage prices are decreasing, SSD's are worth the price at current market value. Startup between an SSD and HDD creates a very big gap in startup times. SSD's will be able to get you to your desktop very quickly after you press your power button. It also makes windows, linux, or whatever you use feel a lot more responsive. As you can see by the benchmark, the SSD is able to read and write faster than the HDD.

Should I get one?

Well this absolutely depends. Are you gaming? Do you do photoshop work? Is your computer feeling rather sluggish? Are you angry because everytime you open a program it takes a year and a half to complete opening?

If you said yes to any of those then you should probably get one (Especially if you said yes to the last one, and while you're doing that some anger management will go a long way). If you have never had the joy of owning an SSD I highly recommend getting one. If you don't have much money to drop on storage (And I totally understand that feeling) then I suggest going with a 60GB SSD or 120GB SSD. Then reformat to have your operating system on the SSD. You will definitely feel a big difference in performance.
