SSDs vs HDDs
Compare the 2 industry–leading data storage systems
When you have a website or an application, rate of operation is really important. The swifter your site performs and then the swifter your web apps operate, the better for you. Given that a web site is simply a selection of files that communicate with one another, the devices that keep and access these data files have an important role in website general performance.
Hard disks, or HDDs, have been, until the past several years, the most dependable products for saving data. Nevertheless, lately solid–state drives, or SSDs, are already gaining interest. Take a look at our comparison chart to view whether HDDs or SSDs are better for you.
1. Access Time
Due to a revolutionary new approach to disk drive performance, SSD drives make it possible for faster data access rates. Having an SSD, data access times are much lower (as low as 0.1 millisecond).
The technology driving HDD drives goes back to 1954. And while it’s been drastically processed as time passes, it’s even now no match for the innovative technology driving SSD drives. Having today’s HDD drives, the top data file access speed you can actually achieve differs in between 5 and 8 milliseconds.
2. Random I/O Performance
On account of the same radical approach that allows for faster access times, it is possible to appreciate greater I/O efficiency with SSD drives. They can complete two times as many functions during a given time compared with an HDD drive.
An SSD can manage a minimum of 6000 IO’s per second.
Hard drives offer reduced data access speeds as a result of aging file storage and accessibility technology they are implementing. And in addition they demonstrate much slower random I/O performance when compared with SSD drives.
Throughout 1stWebHosting4U.com’s trials, HDD drives managed typically 400 IO operations per second.
3. Reliability
SSD drives are designed to have as less rotating parts as is feasible. They use an identical technique to the one found in flash drives and are also more dependable in comparison with conventional HDD drives.
SSDs come with an typical failing rate of 0.5%.
As we have documented, HDD drives rely upon spinning disks. And something that takes advantage of numerous moving elements for extended periods of time is more prone to failing.
HDD drives’ typical rate of failure varies between 2% and 5%.
4. Energy Conservation
SSD drives are usually smaller than HDD drives as well as they don’t have any kind of moving elements whatsoever. Because of this they don’t generate just as much heat and need significantly less electricity to work and less power for chilling purposes.
SSDs use up somewhere between 2 and 5 watts.
HDD drives are renowned for staying loud. They require further electric power for cooling applications. Within a web server that has a lot of HDDs running continuously, you’ll need a lot of fans to ensure that they’re cool – this makes them far less energy–effective than SSD drives.
HDDs consume between 6 and 15 watts.
5. CPU Power
The faster the data file accessibility rate is, the faster the data requests will be handled. As a result the CPU will not have to save assets looking forward to the SSD to answer back.
The common I/O wait for SSD drives is actually 1%.
HDD drives allow for sluggish accessibility rates in comparison with SSDs do, resulting for the CPU having to hang around, while arranging assets for the HDD to discover and give back the demanded file.
The standard I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
In the real world, SSDs perform as wonderfully as they have for the duration of 1stWebHosting4U.com’s testing. We competed a full system back–up on one of our own production machines. Over the backup operation, the common service time for I/O queries was basically under 20 ms.
In comparison to SSD drives, HDDs deliver considerably sluggish service times for input/output demands. Throughout a server backup, the regular service time for an I/O query ranges somewhere between 400 and 500 ms.
7. Backup Rates
Discussing backups and SSDs – we have noticed a significant progress in the back up rate as we moved to SSDs. Right now, a typical web server data backup will take solely 6 hours.
On the flip side, on a server with HDD drives, the same back–up can take three to four times as long to complete. An entire back–up of any HDD–equipped server usually takes 20 to 24 hours.
To be able to easily boost the performance of your websites with no need to modify any code, an SSD–driven hosting service will be a great solution. Have a look at our Linux cloud website hosting packages packages and the Linux VPS hosting packages – our solutions include fast SSD drives and are available at the best prices.
