The difference between the speeds of hard drives and SSD is about the same as between them and floppy disks. So, what happened when I tried to access different files from the drive at the same time? Yes, things got worse. Right?
And now imagine that there are diskettes in the server with your site. As a result, only frequent brakes and irritation instead of quiet work.
THIS IS WHAT HAPPENS ON A SERVER WITH A CONVENTIONAL HDD
Many arguments on “RAID” reached nowhere; that RAID arrays and large amounts of memory solve the problem – but it’s not! The volume of the disk system will always be much larger than any amount of memory in the server. So it’s impossible to place the entire disk in the cache. Most of the files will still be read from the hard drives.
ON PRACTICE NOTES!
Any inexpensive hosting involves a large number of customers and a huge number of sites on a single server.
In reality, it turns out that more visited sites occupy all the cache of the server with their files. And all the rest get only “leftovers” – LOL. To give visitors the files from these sites, the server has to take them from the disk. But thousands of sites and at any time can require simultaneous access to dozens of different files, which total hundreds of thousands and they are all in different parts of the hard drive. And RAID arrays can only speed up the speed of linear reading, but not the speed of access.
It is here that the SSD drive shows its best side – almost zero access time. And no RAID arrays will help hard drives even approach this parameter to SSD.
On the Internet, you can find a large number of tests of various SSD drives, and everywhere in the webserver test, they show a huge gap from the usual HDD.
However, one must realize that are many things that depend on the site itself. If you use heavy cms scripts that perform a huge number of operations before each page return, then a lightning jump across pages (like this site) may not be there. But the positive difference in speed when switching from a server that uses HDD, you definitely will notice.
There is a stereotype that SSD is not reliable. But this applies only to cheap varieties on MLC cells. On our hosting servers, we use Intel E5-2680 & E5-2660 V2 SSD on SLC cells. For which you can write about 2,000,000 GB of information. But since on the webserver the main signals are the requests for reading, this limit will last for tens of years. So, will it be possible to run as many ordinary hard drives without fail?
Also, the stability of characteristics is very important. Many home SSDs can show significantly higher speeds compared to enterprise-class SSDs. However, over time, such a disk is filled with data and the write speed can drop so much that even ordinary HDDs can be faster. In server-based SSD, the emphasis is not on records, but on the constancy of speed. In the Intel E5-2680 & E5-2660 V2 we used, the recording speed remains constantly high at all times.
The server is only half responsible for the speed of loading pages. The other half is the Internet channel. Am I missing out on something?
Hence, by requesting a site located at the other end of the Earth, it simply cannot physically be loaded as quickly as if it were on a server within the same country. The access time to each file will be different tens of times. Thus, the difference in speed will be even more noticeable with the increase in the number of simultaneously requested files. For example, one page with text will be downloaded about as quickly from a server in the US and Ukraine. However, if there are many photos on this page, the difference will be much more noticeable.
Thus, if the main target audience of your site is in Asian or American geolocations, then hosting should be located in India.
In order not to make your visitors nervous from the slow loading of each page, it is advisable to use SSD hosting in India from Ideastack Solutions.
With us, you can choose the most suitable fare based on the size of your sites. It may seem a little at first glance, especially given how much today most hosts provide. But do not forget that the capacity of SSD is much smaller than usual hard disks and it is simply impossible to provide the same disk space as others. However, most small sites are simply not necessary anymore. And to be on the same server with large sites, the more you do not need anyone. Since they will take away most of the server resources, and your sites will not boot as fast as they could or used to.
Now many people offer web hosting with SSD disks, but be careful and specify which disks are used. Although you can guess yourself – when there is a lot of disk space, it is very likely that SSDs are used one of the cheapest, which often quite quickly fail even when used on home computers. Not to mention around the clock working with a high load server.
Also, do not forget that the channel on the Internet from the server is one for all users. And if you have a lot of disk space, then surely your neighbors on the server will handle large amounts of data passing through this common channel. So it can also become a bottleneck between your site and its visitors.
