SSDs vs HDDs
Review the two industry–leading data storage systems
For years there was just one reputable way to keep information on a laptop – working with a hard drive (HDD). However, this kind of technology is already displaying its age – hard disks are really loud and slow; they are power–hungry and have a tendency to generate a lot of warmth in the course of serious procedures.
SSD drives, on the contrary, are quick, use up significantly less energy and are generally far less hot. They feature a completely new method of file access and storage and are years in advance of HDDs with regards to file read/write speed, I/O efficiency as well as power effectivity. Discover how HDDs stand up up against the newer SSD drives.
1. Access Time
Due to a revolutionary new method of disk drive operation, SSD drives allow for much quicker file accessibility rates. Having an SSD, file access times tend to be lower (as small as 0.1 millisecond).
The technology powering HDD drives goes all the way to 1954. And even while it’s been drastically refined throughout the years, it’s even now can’t stand up to the ingenious concept powering SSD drives. Utilizing today’s HDD drives, the very best file access speed you can actually reach differs between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is extremely important for the effectiveness of a data file storage device. We’ve executed in depth exams and have confirmed an SSD can manage no less than 6000 IO’s per second.
Hard drives deliver slower data file access speeds because of the older file storage space and access technology they’re by making use of. And in addition they illustrate substantially sluggish random I/O performance as compared with SSD drives.
In the course of HialeahHosting.com’s trials, HDD drives handled around 400 IO operations per second.
3. Reliability
SSD drives don’t have any sort of moving parts, meaning there is a lot less machinery in them. And the fewer literally moving elements you’ll find, the fewer the probability of failure will be.
The average rate of failure of any SSD drive is 0.5%.
HDD drives implement spinning disks for holding and browsing files – a concept dating back to the 1950s. And with disks magnetically suspended in mid–air, rotating at 7200 rpm, the chances of anything going wrong are much higher.
The standard rate of failing of HDD drives varies amongst 2% and 5%.
4. Energy Conservation
SSD drives operate almost soundlessly; they don’t generate extra heat; they don’t require extra chilling solutions and then use up way less power.
Lab tests have revealed the common power use of an SSD drive is somewhere between 2 and 5 watts.
HDD drives are infamous for being loud; they are more prone to getting too hot and in case you have several disk drives in a web server, you have to have an extra a / c unit used only for them.
All together, HDDs use up in between 6 and 15 watts.
5. CPU Power
The swifter the data file access speed is, the quicker the data file demands will likely be processed. This means that the CPU will not have to reserve allocations waiting around for the SSD to reply back.
The regular I/O delay for SSD drives is actually 1%.
By using an HDD, you will have to dedicate more time waiting around for the outcome of your data file query. Consequently the CPU will remain idle for more time, expecting the HDD to respond.
The average I/O delay for HDD drives is about 7%.
6.Input/Output Request Times
In real life, SSDs carry out as perfectly as they did during HialeahHosting.com’s testing. We ran a full system data backup using one of our own production servers. Throughout the backup process, the average service time for any I/O calls was basically below 20 ms.
Using the same server, but this time equipped with HDDs, the outcome were totally different. The normal service time for any I/O request fluctuated between 400 and 500 ms.
7. Backup Rates
You can experience the real–world advantages of using SSD drives day by day. As an example, with a server designed with SSD drives, a complete back–up can take just 6 hours.
On the flip side, on a hosting server with HDD drives, an identical back–up can take three or four times as long to finish. A full back up of any HDD–equipped hosting server may take 20 to 24 hours.
With HialeahHosting.com, you can get SSD–powered web hosting services at inexpensive price points. Our Linux shared hosting can include SSD drives by default. Get an website hosting account along with us and witness the way your sites will become far better instantly.
