For decades there seemed to be one efficient option to store data on your personal computer – using a hard drive (HDD). However, this type of technology is by now showing it’s age – hard disks are really loud and sluggish; they are power–ravenous and tend to produce a lot of heat during serious operations.
SSD drives, on the other hand, are really fast, take in a lesser amount of energy and tend to be far less hot. They offer an innovative way of file accessibility and storage and are years in advance of HDDs when considering file read/write speed, I/O efficiency and power effectivity. Observe how HDDs stand up up against the more recent SSD drives.
1. Access Time
SSD drives present a fresh & revolutionary way of data storage based on the use of electronic interfaces instead of any moving parts and rotating disks. This innovative technology is faster, permitting a 0.1 millisecond file accessibility time.
HDD drives even now use the very same general data file access concept that’s actually created in the 1950s. Though it has been vastly upgraded after that, it’s slower compared to what SSDs are offering. HDD drives’ data file access rate varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Because of the brand new radical data file storage strategy adopted by SSDs, they give you quicker file access rates and quicker random I/O performance.
For the duration of our lab tests, all of the SSDs demonstrated their ability to deal with at least 6000 IO’s per second.
Over the same tests, the HDD drives proved to be significantly slower, with 400 IO operations managed per second. Although this seems to be a great number, for people with a busy server that hosts a great deal of well–liked sites, a slow harddrive may lead to slow–loading web sites.
The absence of moving parts and rotating disks inside SSD drives, and also the recent advancements in electric interface technology have generated a significantly reliable data storage device, having an normal failing rate of 0.5%.
Since we have previously mentioned, HDD drives use rotating disks. And something that works by using numerous moving components for continuous time frames is at risk of failure.
HDD drives’ common rate of failure can vary among 2% and 5%.
4. Energy Conservation
SSD drives work nearly soundlessly; they don’t generate excessive heat; they don’t require supplemental air conditioning options as well as use up significantly less power.
Trials have established the average power consumption of an SSD drive is amongst 2 and 5 watts.
From the second they have been created, HDDs have invariably been very electrical power–greedy products. So when you have a server with many different HDD drives, this will increase the regular monthly utility bill.
Normally, HDDs take in in between 6 and 15 watts.
5. CPU Power
The faster the data accessibility rate is, the swifter the file queries are going to be treated. Therefore the CPU do not need to reserve assets expecting the SSD to respond back.
The standard I/O delay for SSD drives is simply 1%.
HDD drives allow for sluggish accessibility rates when compared with SSDs do, which will result in the CPU required to delay, although scheduling assets for the HDD to find and return the demanded data.
The typical I/O delay for HDD drives is just about 7%.
6.Input/Output Request Times
The bulk of HostSkye.com’s new web servers are now using exclusively SSD drives. Our own lab tests have demonstrated that having an SSD, the typical service time for any I/O request whilst doing a backup remains below 20 ms.
Sticking with the same hosting server, but this time built with HDDs, the effects were very different. The regular service time for any I/O query fluctuated between 400 and 500 ms.
7. Backup Rates
A different real–life advancement will be the rate with which the back–up was made. With SSDs, a web server backup today takes under 6 hours by using our web server–designed software solutions.
On the other hand, on a hosting server with HDD drives, a similar back–up will take three to four times as long in order to complete. An entire back–up of an HDD–powered web server may take 20 to 24 hours.
