For years there was just one single reputable solution to keep data on a personal computer – by using a hard disk drive (HDD). Having said that, this type of technology is presently showing its age – hard drives are really noisy and sluggish; they are power–ravenous and tend to create a lot of heat during serious operations.

SSD drives, on the contrary, are quick, use up far less power and are generally far less hot. They provide a completely new solution to file accessibility and data storage and are years in advance of HDDs in relation to file read/write speed, I/O efficiency and also power effectivity. Find out how HDDs stand up up against the more recent SSD drives.

1. Access Time

Image

With the launch of SSD drives, data access rates have gone tremendous. Thanks to the brand new electronic interfaces employed in SSD drives, the standard data access time has been reduced into a record low of 0.1millisecond.

Image

HDD drives continue to make use of the exact same basic file access concept that’s originally created in the 1950s. Although it has been noticeably upgraded since that time, it’s slower compared with what SSDs are offering to you. HDD drives’ file access speed varies between 5 and 8 milliseconds.

2. Random I/O Performance

Image

The random I/O performance is important for the general performance of any file storage device. We have carried out in depth lab tests and have confirmed an SSD can handle at least 6000 IO’s per second.

Image

With a HDD drive, the I/O performance progressively increases the more you use the hard drive. Even so, right after it actually reaches a particular limitation, it can’t proceed quicker. And due to the now–old technology, that I/O limitation is noticeably less than what you might receive having an SSD.

HDD are only able to go as much as 400 IO’s per second.

3. Reliability

Image

SSD drives lack any moving components, meaning that there is far less machinery included. And the fewer actually moving parts you can find, the fewer the likelihood of failure are going to be.

The standard rate of failing of any SSD drive is 0.5%.

Image

As we have already observed, HDD drives rely on rotating hard disks. And something that employs a number of moving components for prolonged periods of time is more likely to failure.

HDD drives’ average rate of failure varies between 2% and 5%.

4. Energy Conservation

Image

SSDs do not have moving components and need not much chilling power. Additionally they need not much power to perform – tests have shown that they can be powered by a normal AA battery.

As a whole, SSDs take in amongst 2 and 5 watts.

Image

HDD drives are renowned for being loud; they can be liable to overheating and when there are several disk drives in a hosting server, you will need an additional a / c unit used only for them.

All together, HDDs consume between 6 and 15 watts.

5. CPU Power

Image

The faster the data file accessibility rate is, the sooner the data file demands will be processed. Therefore the CPU won’t have to save assets waiting around for the SSD to respond back.

The regular I/O wait for SSD drives is actually 1%.

Image

By using an HDD, you need to dedicate time anticipating the outcomes of your data file call. As a result the CPU will remain idle for much more time, waiting around for the HDD to react.

The common I/O wait for HDD drives is around 7%.

6.Input/Output Request Times

Image

In the real world, SSDs perform as admirably as they did during the testing. We ran an entire platform data backup using one of our own production machines. Through the backup operation, the common service time for I/O queries was basically under 20 ms.

Image

Compared with SSD drives, HDDs provide much reduced service times for input/output queries. Throughout a hosting server backup, the regular service time for an I/O call varies somewhere between 400 and 500 ms.

7. Backup Rates

Image

Another real–life improvement will be the rate with which the backup has been developed. With SSDs, a web server back–up now requires under 6 hours by using our web server–designed software solutions.

Image

In the past, we have got employed largely HDD drives on our web servers and we are well aware of their efficiency. With a web server equipped with HDD drives, a full server back–up normally takes about 20 to 24 hours.
