For years there was one trustworthy way to keep information on a computer – having a hard disk drive (HDD). However, this kind of technology is already demonstrating its age – hard disks are actually noisy and sluggish; they’re power–ravenous and have a tendency to produce a great deal of heat for the duration of intensive operations.

SSD drives, however, are swift, take in much less power and are also far less hot. They furnish a whole new strategy to file accessibility and storage and are years in advance of HDDs in terms of file read/write speed, I/O operation and power efficiency. Observe how HDDs stand up up against the newer SSD drives.

1. Access Time

After the release of SSD drives, file access rates have gone tremendous. With thanks to the completely new electronic interfaces made use of in SSD drives, the common data file access time has been reduced towards a record low of 0.1millisecond.

HDD drives still utilize the same fundamental file access concept that was originally created in the 1950s. Although it was noticeably improved since that time, it’s slow in comparison to what SSDs are providing. HDD drives’ data file access rate ranges in between 5 and 8 milliseconds.

2. Random I/O Performance

Due to the very same radical approach which enables for speedier access times, it is possible to appreciate better I/O efficiency with SSD drives. They will conduct two times as many procedures during a specific time compared to an HDD drive.

An SSD can manage at the least 6000 IO’s per second.

With a HDD drive, the I/O performance steadily raises the more you employ the hard drive. Having said that, right after it reaches a particular cap, it can’t get faster. And due to the now–old concept, that I/O limit is noticeably less than what you can have with a SSD.

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

3. Reliability

SSD drives are built to have as fewer moving parts as is possible. They utilize a comparable technique to the one found in flash drives and are generally much more efficient when compared with regular HDD drives.

SSDs offer an average failing rate of 0.5%.

HDD drives work with rotating disks for storing and browsing data – a concept dating back to the 1950s. And with hard disks magnetically suspended in mid–air, rotating at 7200 rpm, the probability of anything going wrong are generally bigger.

The common rate of failure of HDD drives varies amongst 2% and 5%.

4. Energy Conservation

SSD drives function practically noiselessly; they don’t produce extra heat; they don’t involve additional cooling down options and take in considerably less energy.

Tests have indicated the average electrical power consumption of an SSD drive is between 2 and 5 watts.

As soon as they have been designed, HDDs have invariably been very electric power–heavy equipment. When you have a server with several HDD drives, this tends to raise the regular monthly power bill.

Typically, HDDs use up somewhere between 6 and 15 watts.

5. CPU Power

Because of SSD drives’ higher I/O effectiveness, the main server CPU can easily work with data file requests more rapidly and save time for additional operations.

The normal I/O delay for SSD drives is exactly 1%.

In comparison with SSDs, HDDs enable reduced data file access rates. The CPU will need to await the HDD to return the inquired file, saving its assets in the meanwhile.

The regular I/O delay for HDD drives is around 7%.

6.Input/Output Request Times

It’s about time for several real–world examples. We, at arunared, produced a complete system backup on a server using only SSDs for data storage purposes. In that process, the standard service time for an I/O call remained below 20 ms.

With the same server, however, this time built with HDDs, the effects were completely different. The common service time for an I/O call fluctuated somewhere between 400 and 500 ms.

7. Backup Rates

Talking about backups and SSDs – we’ve witnessed a great progress in the back up speed since we moved to SSDs. Today, a regular hosting server backup can take just 6 hours.

We applied HDDs mainly for a couple of years and we have pretty good comprehension of how an HDD functions. Creating a backup for a web server equipped with HDD drives will take about 20 to 24 hours.

Should you wish to right away add to the general performance of your websites and not having to transform any code, an SSD–operated website hosting service is really a excellent option.
