SSDs vs HDDs
Learn which data storage service is better for your web hosting account
For many years there was only 1 efficient path to keep info on a computer – by using a disk drive (HDD). Nonetheless, this kind of technology is already showing it’s age – hard disks are actually loud and slow; they’re power–hungry and tend to generate a lot of warmth during intensive operations.
SSD drives, on the other hand, are really fast, take in a smaller amount energy and they are much cooler. They provide a brand new solution to file accessibility and data storage and are years in front of HDDs with regards to file read/write speed, I/O performance and also energy efficiency. Observe how HDDs stand up against the newer SSD drives.
1. Access Time
With the launch of SSD drives, data access rates are now through the roof. On account of the unique electronic interfaces utilised in SSD drives, the common file access time has been reduced to a record low of 0.1millisecond.
HDD drives even now work with the exact same basic data access technology that’s actually developed in the 1950s. Even though it has been noticeably upgraded consequently, it’s slow as compared to what SSDs are offering to you. HDD drives’ data access rate ranges in between 5 and 8 milliseconds.
2. Random I/O Performance
As a result of the new significant data file storage solution adopted by SSDs, they feature faster data access rates and quicker random I/O performance.
Throughout nameURsite’s trials, all of the SSDs showed their capability to deal with a minimum of 6000 IO’s per second.
Hard drives deliver slower data file access speeds as a result of older file storage and accessibility technology they are by making use of. And they also exhibit substantially slower random I/O performance matched against SSD drives.
For the duration of our lab tests, HDD drives managed an average of 400 IO operations per second.
3. Reliability
SSD drives are meant to include as fewer moving components as is practical. They use an identical technology like the one employed in flash drives and are also significantly more reliable in comparison with standard HDD drives.
SSDs come with an common failure rate of 0.5%.
HDD drives use spinning disks for storing and browsing info – a technology going back to the 1950s. Along with disks magnetically hanging in mid–air, spinning at 7200 rpm, the prospect of anything failing are much bigger.
The common rate of failing of HDD drives ranges among 2% and 5%.
4. Energy Conservation
SSD drives are far smaller than HDD drives and they do not have just about any moving parts whatsoever. Consequently they don’t produce as much heat and require less power to function and fewer power for cooling down reasons.
SSDs take in amongst 2 and 5 watts.
From the minute they were built, HDDs have invariably been quite energy–heavy equipment. So when you’ve got a web server with quite a few HDD drives, this will likely increase the regular utility bill.
Normally, HDDs consume between 6 and 15 watts.
5. CPU Power
SSD drives allow for swifter file access speeds, that, in turn, allow the CPU to accomplish file queries much quicker and to return to different tasks.
The common I/O hold out for SSD drives is barely 1%.
When using an HDD, you’ll have to invest additional time waiting around for the outcome of one’s data file call. As a result the CPU will stay idle for more time, looking forward to the HDD to reply.
The typical I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
In real life, SSDs operate as perfectly as they did for the duration of nameURsite’s lab tests. We competed a complete system back–up using one of our own production machines. All through the backup operation, the average service time for any I/O queries was basically under 20 ms.
Sticking with the same hosting server, but this time loaded with HDDs, the results were different. The normal service time for an I/O call changed in between 400 and 500 ms.
7. Backup Rates
Referring to back–ups and SSDs – we have noticed an amazing development with the data backup rate since we switched to SSDs. Currently, a common hosting server backup requires merely 6 hours.
In the past, we have worked with primarily HDD drives on our servers and we are knowledgeable of their general performance. On a server pre–loaded with HDD drives, an entire web server back–up may take about 20 to 24 hours.
To be able to instantaneously improve the overall performance of your respective web sites with no need to transform any code, an SSD–operated web hosting solution is a great alternative. Take a look at our Linux shared services packages and additionally our Linux VPS web hosting services – these hosting solutions highlight fast SSD drives and are available at good prices.
