I have an old HP Envy x360 with AMD FX 7th generation processor and a very slow 5400rpm 1TB disk. Once I upgraded this to Windows 10 several years ago, I really felt the impact of the slow disk during the Windows 10 start up time. Also when multiple applications were accessing disks (such as multiple Windows updates downloading and one is getting installed), the whole laptop came to the grinding halt.I debated purchasing a new laptop, but with already a work system, tablet, and a phone, I did not really want to spend a money in buying a new laptop just to use it once in a while. So, the next option I pursued was to look at upgrading the hard drive.I looked at hybrid disks first but they all seem to come with 5400rpm disk as the main storage, and I had enough of slow disk. When I started to look at SSD's, I read up on all of articles and reviews, and all roads seem to lead to Samsung SSD's for consumer uses. However, Samsung SSD's never seem to go on a sale and they had higher price tags than others.I came across Hynix SSD's by chance. Many of reviewers highly recommended Hynix Gold SSD's after they put Hynix Gold line SSD's against those from Samsung and Micron, and the results were looking pretty convincing. I knew Hynix as high quality memory manufacturer and Hynix Gold 1TB SSD was priced just low enough for me to be tempted. Amazon running a pretty aggressive discount was just an icing on the cake.I placed the Hynix SSD in the external drive case and used the Hynix clone tool (read Macrium) to make a copy of my slow 1TB disk. It went without a hitch in about 2 1/2 hours, and, after few choice swearing words during taking HP Envy apart, I replaced the disk.My work system is high end with SSD, so I am used to the fast boot time. However, when my home system booted up for the first time with the Hynix SSD, it was such a night and day compared to the old 5400rpm disk. I actually thought that I booted up my work system. Once I logged in, I saw the enough lags to realize that I was using my home system. That's right. Hynix SSD can speed up your old system, but it cannot make up for a slow AMD CPU :)I ran few different benchmarks to confirm the numbers many reviewers were seeing. I have included an output from one of tools, but these numbers are pretty consistent across different tools. So,- If you are still running an old magnetic disks (especially those 5400rpm ones) on your laptop, then do yourself a favor and get yourself an SSD.- Hynix SSD seems to have pretty darn good performance number to back up its "gold" label.- With the current Amazon sale, it makes Hynix SSD's cheaper that low performing SSD's from no name vendors.It used to be that spending $100 - $150 to add more memory to your system was the trick to revitalize your old system, and it seems like the new trick is to replace your slow magnetic disks with SSD's. I am ecstatic with the initial performance so far.
