SSD stands for Solid State Drive. Basically this is the latest type of data storage device and there are a number of benefits to using SSD Hosting but the headlines are that it is super fast and reliable.
Let’s look at SSD in more detail.
What’s The Difference Between SSD And Traditional Hard Drives?
Traditional hard drives work on the basis that data is stored on data platters (drives) that spin very quickly and data is written to and read from the drives by a data arm. They are often referred to as ‘Spinning Disks’ and despite recent enhancements they are essentially mechanical devices which operate on the same basis as hard drives used in the 1960’s and 1970’s.
SSDs on the other hand do not have any moving parts. They are 100% electronic. This means they are much faster than traditional hard drives.
How Fast Are SSDs Compared To Traditional Hard Drives
When it comes to speed SSDs win hands down. The best measure of speed is Inputs Outputs Per Second (IOPS). The most popular type of spinning hard drives currently in use are 7.2K SATA, 10K SAS and 15K SAS. The K refers to the number of revolutions per minute of the disk so 7.2K spins 7,200 times per minute and 15K spins 15,000 times per minute. SATA stands for Serial Advanced Technology Attachment and SAS stands for Serial Attached SCSI (SCSI stands for Small Computer System Interface).
The IOPS speed for a 7.2K SATA hard drive is roughly 80 IOPS. For a 10K SATA this increases to around 120 to 130 IOPS whilst 15K SAS drives operate in a range of between 180 to 200 IOPS.
A typical Datacentre ready SSD can operate at ranges between 4,600 IOPS (Random Writes) to 75,000 IOPS (Random Reads).
Why Is Disk Speed Important?
Disk speed is important for the simple reason that your website will perform faster. That means the pages will load faster when people browse them and if you are using a database then it will perform database functions much faster.
This results in a better experience for the person using your website. Of course there are many factors that make a website faster, but using SSD Hosting is one of the easiest and cheapest ways to speed up your website.
But having a fast website isn’t just about bragging rights. Google’s search algorithm measures many metrics when determining where to position a website in its ranking and one of Google’s known factors is speed. Simply put, if your website is faster it will help improve your search ranking and will help to bring more visitors to your website. It isn’t the only factor, but it will help.
Does Pickaweb Offer SSD Hosting?
Yes, we do.
Pickaweb´s SSD Hosting is offered on our Shared SSD Hosting, SSD Reseller Hosting, SSD VPS Hosting and Dedicated SSD Server plans.
What Types Of SSD Does Pickaweb Use?
Pickaweb only uses Datacentre ready SSDs. These are SSDs that are specifically designed to handle the more demanding needs of datacentre based systems. An example of the type of SSD that we use is the Intel DC S3500 SSD.
These SSDs are not to be confused with cheaper laptop or desktop type SSDs.
Why Is SSD More Expensive?
SSD technology is relatively new so that is one reason why it is more expensive than SATA or SAS hard drives.
Another reason is that they do not offer the same density of GB per disk. For example 3.5 inch 7.2K SATA drives can reach up to 8TB although they are normally deployed in the 1 to 3TB range. With SSDs the range is around 240GB to 480GB so they require more servers to offer the same amount of space.
How Much Energy Do SSDs Use?
Another area where SSDs offer an advantage of traditional drives is in terms of energy consumption. Typically they consume around 20 to 30% of the electricity than a SATA hard drive.
Aside from this they operate at much cooler temperatures than traditional drives. That is important because it means that they do not generate so much heat and therefore require less cooling in the datacentre which is a significant saving.
Is SSD Hosting More Reliable?
SSDs are more reliable than traditional drives because there are no moving parts. Traditional hard drives include mechanical parts moving extremely quickly and over time they can degrade and fail due to everyday usage.
The failure rate of hard drives is referred to a Mean Time Between Failure (MTBF) and SSDs can offer MTBF of around 2 million hours. SAS drives offer around 1.2 million hours whilst SATA are around 700,000 hours. It should be noted that these are averages and differences can occur between manufacturers and models.
