SSDs vs HDDs
Discover which storage space service is better for your web hosting account
For years there was a single dependable way to store information on a computer – utilizing a hard disk drive (HDD). However, this kind of technology is actually expressing its age – hard disk drives are actually noisy and slow; they’re power–ravenous and are likely to produce lots of heat throughout intensive operations.
SSD drives, on the contrary, are really fast, consume significantly less energy and are also much cooler. They offer an innovative strategy to file accessibility and data storage and are years in advance of HDDs when considering file read/write speed, I/O efficiency and power efficiency. See how HDDs fare against the newer SSD drives.
1. Access Time
Resulting from a revolutionary new approach to disk drive performance, SSD drives make it possible for considerably faster file accessibility speeds. With an SSD, data access times are much lower (just 0.1 millisecond).
The technology behind HDD drives goes all the way back to 1954. And although it’s been drastically enhanced through the years, it’s still can’t stand up to the revolutionary concept behind SSD drives. Using today’s HDD drives, the highest file access rate it is possible to achieve can vary in between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the unique significant file storage approach shared by SSDs, they feature quicker file access speeds and speedier random I/O performance.
Throughout Savannah Domains’s trials, all SSDs showed their ability to handle no less than 6000 IO’s per second.
Hard drives offer reduced data access speeds as a result of older file storage space and access concept they are by making use of. Additionally they show much sluggish random I/O performance when compared with SSD drives.
During Savannah Domains’s trials, HDD drives managed around 400 IO operations per second.
3. Reliability
SSD drives are designed to have as fewer rotating components as feasible. They use a comparable technology like the one utilized in flash drives and are generally significantly more efficient in comparison to classic HDD drives.
SSDs offer an normal failure rate of 0.5%.
HDD drives use rotating hard disks for storing and reading info – a technology dating back to the 1950s. With hard disks magnetically suspended in mid–air, spinning at 7200 rpm, the possibilities of one thing going wrong are usually bigger.
The regular rate of failing of HDD drives ranges among 2% and 5%.
4. Energy Conservation
SSD drives work almost soundlessly; they don’t produce extra warmth; they don’t demand more cooling down options as well as use up much less electricity.
Trials have demonstrated the normal electric power utilization of an SSD drive is somewhere between 2 and 5 watts.
HDD drives are known for being noisy; they’re at risk from heating up and if you have several hard drives in a web server, you need one more air conditioning system exclusively for them.
All together, HDDs take in between 6 and 15 watts.
5. CPU Power
The quicker the data access speed is, the quicker the file requests will be handled. Therefore the CPU won’t have to reserve resources waiting for the SSD to reply back.
The standard I/O delay for SSD drives is simply 1%.
When you use an HDD, you have to invest time looking forward to the outcome of your file call. This means that the CPU will stay idle for more time, expecting the HDD to react.
The standard I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
In the real world, SSDs conduct as perfectly as they managed throughout the testing. We competed an entire platform back–up using one of the production machines. Through the backup process, the standard service time for I/O demands was in fact under 20 ms.
In comparison to SSD drives, HDDs deliver substantially sluggish service rates for I/O queries. During a server backup, the normal service time for an I/O call can vary somewhere between 400 and 500 ms.
7. Backup Rates
You can easily check out the real–world added benefits of having SSD drives on a regular basis. For example, on a web server built with SSD drives, a complete back up is going to take merely 6 hours.
In the past, we’ve got made use of largely HDD drives with our web servers and we are well aware of their performance. On a web server pre–loaded with HDD drives, a complete hosting server backup often takes about 20 to 24 hours.
To be able to immediately add to the general performance of your web sites while not having to change any code, an SSD–driven website hosting solution will be a really good alternative. Have a look at Savannah Domains’s shared website hosting – our services have fast SSD drives and are offered at affordable prices.
