Review: Light and Fast!! Does what its supposed to - Silicon Power is a good SSD no matter what some of the other comments here say. Its not the same say as Samsung but its close enough in terms of quality and speed, the two most important factors when deciding on a SSD. Hey if you really wanted a Samsung then you should go out, pay the fancy price and buy it. Yes I agree that Samsung reliability would be 100% but this ain't too bad either. I already own a Samsung SSD drive and wanted something budget friendly this time. Their Velox series is more for people who are exploring SSD's for the first time. This model Ace A55 is budget friendly mid range SSD which is good for laptops. The best part is that it is smaller in thickness and hence really low on weight. But it may lead to heating in the future as the thicker ones usually have better chip design and cooling built into them. I will know this summer. If installing in a laptop it will make a difference even if you already have other SSD's installed like the M.2 PCIe Gen 3 and have replaced your laptop DVD writer also with an Samsung SSD drive like me. Coming to the speed, a user here has already written an important and very helpful comment, you need to align the SSD partitions and sectors correctly if you want it to perform especially when cloning your old HDD and Windows partitions to it. I suggest the same thing and recommend using Mini Tool Partition to align the partitions to 1MB by default. I didn't need to do all this as its not the primary SSD in my laptop and not going to be the last one either but yes for my primary SSD I did need to. Where this SSD really boosts up speed is on a Macbook. Trust me when I say this but booting up MacOS using a SSD is going to feel supersonic as compared to booting up a HP Pavillion Windows 10. But yes die hard Windows fans a SSD is going to improve your loading and waiting times immensely. Its damn irritating waiting for all the tray icons to load even if you have 16 GB of RAM. For the geeks out there plenty of tests are available to check out the speed of this SSD and I think Silicon Power does not do too poorly in most of them for a mid range SSD. You can also download their ToolBox to test your drives health from time to time. They even provide a licensed cloning software if you dont have Acronis or Mini Tool. As with all my reviews I must post a little caveat, most low to medium priced SSD's including this one require some amount of system RAM to function correctly. So if you buy a SSD like this one 512 GB then be prepared to sacrifice at least 1 GB of RAM to the SSD for its caching tasks etc. That can make a difference on an old 4 GB RAM system especially if you share RAM with the inbuilt Graphics card as well. Therefore first upgrade the RAM on your old PC or laptop and then buy a SSD especially if you intend to use it for high processing power work later and really breathe life into your old system. On older systems a SSD does make a difference but where it really shines would be on a system with adequate processing power and RAM. Also please note 512 GB does not mean it will effectively show up as 512 GB for use on a Windows laptop. Its the way to do with the way the file system reports the effective space on Microsoft based systems when formatted for Windows use. On a Mac it will show up correctly as 512 GB as they have changed their operating system to report the space/size correctly. But its there on both systems as the effective size provided by the manufacturer SP has not gone anywhere. All in all go for this SSD if you want to bump your old Desktop or laptop by a notch when working or gaming by spending a little. If you want to know specifics suggest you visit the manufacturers website and look for Ace A55 which is the model number for this SSD. Its the starting model in their Ace series. For those looking to buy something more pocket friendly I suggest getting this. I am not going to explain 3D NAND etc as it does not matter to most users here but lets just say this does the job in the price you paid.
