Today, all of the brand new computers are equipped with SSD drives as an alternative to HDD drives. You’ll notice superlatives on them everywhere in the specialised press – that they are a lot faster and operate better and they are actually the future of home computer and laptop computer manufacturing.

Nevertheless, how do SSDs perform inside the web hosting community? Can they be responsible enough to replace the successful HDDs? At Valitan, we’ll aid you much better see the distinctions between an SSD and an HDD and decide the one that best fits you needs.

1. Access Time

With the launch of SSD drives, data accessibility speeds have gone over the top. On account of the brand new electronic interfaces used in SSD drives, the common data file access time has been reduced towards a record low of 0.1millisecond.

HDD drives continue to make use of the same basic data access concept that was actually developed in the 1950s. Although it has been vastly enhanced consequently, it’s sluggish as compared to what SSDs are offering to you. HDD drives’ file access rate varies somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

The random I/O performance is important for the efficiency of any data file storage device. We’ve conducted in depth trials and have identified that an SSD can manage no less than 6000 IO’s per second.

Having an HDD drive, the I/O performance gradually enhances the more you employ the disk drive. Nonetheless, as soon as it reaches a particular restriction, it can’t get swifter. And due to the now–old concept, that I/O cap is noticeably below what you might get with a SSD.

HDD can only go as much as 400 IO’s per second.

3. Reliability

SSD drives are created to have as fewer moving parts as feasible. They use a comparable technology to the one found in flash drives and are much more efficient compared with traditional HDD drives.

SSDs offer an normal failure rate of 0.5%.

For an HDD drive to work, it must rotate a couple metallic disks at a minimum of 7200 rpm, keeping them magnetically stable in the air. They have a good deal of moving parts, motors, magnets along with other devices packed in a tiny place. Consequently it’s obvious why the average rate of failure of an HDD drive ranges in between 2% and 5%.

4. Energy Conservation

SSD drives work practically silently; they don’t make excessive warmth; they don’t involve additional chilling options as well as use up much less energy.

Trials have indicated the normal power usage of an SSD drive is between 2 and 5 watts.

HDD drives are famous for being loud. They need further electrical power for chilling reasons. On a server that has a number of HDDs running constantly, you will need a lot of fans to ensure that they’re cooler – this will make them a lot less energy–efficient than SSD drives.

HDDs consume in between 6 and 15 watts.

5. CPU Power

The quicker the data file access speed is, the faster the data file demands will be adressed. It means that the CPU won’t have to save resources waiting for the SSD to respond back.

The common I/O wait for SSD drives is merely 1%.

HDD drives support sluggish accessibility speeds in comparison with SSDs do, resulting for the CPU having to hang on, whilst saving resources for the HDD to locate and give back the requested file.

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

6.Input/Output Request Times

The vast majority of our completely new web servers now use simply SSD drives. Our own lab tests have indicated that with an SSD, the typical service time for any I/O request whilst operating a backup stays below 20 ms.

Sticking with the same hosting server, but this time built with HDDs, the outcome were totally different. The normal service time for an I/O call fluctuated somewhere between 400 and 500 ms.

7. Backup Rates

Referring to back–ups and SSDs – we have noticed an amazing advancement in the back–up speed as we switched to SSDs. Today, a normal server back up will take merely 6 hours.

In the past, we’ve got utilized principally HDD drives on our machines and we’re familiar with their effectiveness. With a web server pre–loaded with HDD drives, a full hosting server backup usually takes about 20 to 24 hours.
