For years there was a single reputable method to keep data on a laptop – employing a disk drive (HDD). Nonetheless, this kind of technology is currently demonstrating its age – hard drives are noisy and sluggish; they’re power–hungry and are likely to generate a great deal of heat throughout serious operations.
SSD drives, on the contrary, are really fast, consume a lesser amount of power and they are much cooler. They offer a brand new solution to file access and storage and are years in front of HDDs relating to file read/write speed, I/O performance and power efficiency. See how HDDs fare against the modern SSD drives.
1. Access Time
After the launch of SSD drives, data access speeds have gone through the roof. As a result of unique electronic interfaces employed in SSD drives, the typical data access time has shrunk towards a all–time low of 0.1millisecond.
HDD drives still work with the very same general file access technique that’s initially created in the 1950s. Although it has been considerably enhanced consequently, it’s slow compared to what SSDs are offering. HDD drives’ data access rate ranges somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the operation of a data file storage device. We’ve run thorough testing and have identified an SSD can handle at least 6000 IO’s per second.
During the exact same trials, the HDD drives proved to be considerably slower, with only 400 IO operations handled per second. While this may appear to be a great number, when you have a busy web server that hosts many sought after sites, a slow harddrive can lead to slow–loading sites.
The absence of moving components and spinning disks in SSD drives, as well as the current advances in electric interface technology have generated a substantially risk–free data file storage device, with an typical failure rate of 0.5%.
As we already have noted, HDD drives use spinning hard disks. And anything that utilizes many moving elements for lengthy periods of time is liable to failing.
HDD drives’ common rate of failure can vary among 2% and 5%.
4. Energy Conservation
SSD drives are considerably small compared to HDD drives and they lack any kind of moving parts whatsoever. As a result they don’t make so much heat and need much less energy to work and less power for cooling down purposes.
SSDs take in between 2 and 5 watts.
From the minute they were developed, HDDs have been quite electric power–ravenous systems. And when you have a server with numerous HDD drives, this will add to the month–to–month power bill.
On average, HDDs consume between 6 and 15 watts.
5. CPU Power
SSD drives enable a lot quicker file accessibility speeds, that, subsequently, allow the CPU to perform data requests much quicker and afterwards to return to different jobs.
The normal I/O wait for SSD drives is only 1%.
If you use an HDD, you will need to dedicate more time waiting around for the outcome of your data call. Consequently the CPU will be idle for additional time, waiting for the HDD to reply.
The typical I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
The bulk of Christian Web Hosting’s completely new web servers now use only SSD drives. Our very own lab tests have demonstrated that utilizing an SSD, the average service time for any I/O request while performing a backup remains under 20 ms.
Compared to SSD drives, HDDs provide much sluggish service rates for input/output requests. Throughout a web server backup, the average service time for any I/O query can vary between 400 and 500 ms.
7. Backup Rates
Speaking about back ups and SSDs – we’ve noticed a significant progress in the back up rate as we switched to SSDs. Right now, a usual server data backup requires solely 6 hours.
On the flip side, on a server with HDD drives, a comparable back up may take three or four times as long to finish. A full back–up of any HDD–driven server usually takes 20 to 24 hours.
