\t\t\t\tYour SSD-based IT environment encounters long load times, it is unresponsive, and generally, it slowed down so much that it is hard to keep your sanity?<\/span><\/p>\n

Well, such a situation makes finishing even simple tasks really frustrating. Apart from the obvious steps like turning the device off and on again (cheers to Roy from IT Crowd!), checking your internet connection, and identifying apps that slow down your computer, you should definitely crack on your drives. Of course, enterprise data storage solutions administrators cannot let their environments waste any time on rebooting the server, as such users need constant availability. So, no Roy, we haven’t turned it off and on again, but we recommend some SSD testing.<\/span><\/p>\n

Checking your HDDs vs SSDs<\/span><\/h2>\n

If you use a <\/span>hard disk drive (HDD)<\/b>, defragmenting your HDD might be helpful. What is the process about? At some point, the collected data might be strewn around the disk. Due to this, the system finds it difficult to localize all the pieces of data required e.g. opening an app, which over time leads to a slow down. Defragging your HDD quickens the process of bringing the pieces of data back together, which helps the system localize the exact data.<\/span><\/p>\n

But, if you use a <\/span>solid-state drive (SSD)<\/b>, there\u2019s no need for defragmenting it, as the technology is completely different from the one used in HDDs.\u00a0<\/span><\/p>\n

So what should you do if you suspect that your SSD might be the reason for the decrease in the speed of your system? In such a case, we recommend testing your SSD\u2019s performance. We even have a ready <\/span>step-by-step guide on how to properly run the SSD performance tests<\/b>.<\/span><\/p>\n

Basics of SSD Performance Tests<\/span><\/h2>\n

Take a look at a series of articles that explain the principles of SSD performance testing and how to interpret the results of such tests.\u00a0<\/span><\/p>\n

In the first part, we\u2019re giving you a background for SSD performance testing, so there\u2019s a simple recap on SSDs. Go to the <\/span>Basics of SSD Performance Tests [1]: Recap on flash memory<\/b><\/a> article.<\/span><\/p>\n

The second part is all about handling the situation when your SSD runs out of free pages. Look at the <\/span>Basics of SSD Performance Tests [2]: Garbage collection<\/b><\/a>. <\/b>What the SSD actually does during garbage collection is rewriting all valid pages from a particular block to a new one.<\/span><\/p>\n

Next, we\u2019re highlighting the issue of performance testing, what \u201cpurging the SSD\u201d is, why it is necessary to run preconditioning, as well as what follows the preconditioning process. Read the <\/span>Basics of SSD Performance Tests [3]: Test, filter, precondition<\/b><\/a> article.<\/span><\/p>\n

Last but not least is, of course, the summary, and we encourage you to also read the <\/span>Basics of SSD Performance Tests [4]: <\/b>In a nutshell <\/b><\/a>article. <\/span><\/p>\n

So, to cut the long story short – what do you definitely need to remember before you start testing the performance of your SSD?<\/span><\/p>\n
