SP Silicon Power 4TB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5'' 7mm (0.28'') Internal Solid State Drive (SP004TBSS3A55S25)

With the ridiculous prices of memory right now this was still a good buy. It’s not huge, but def gets the job done. No issue with installing/mounting.

Works great and is much faster than the previous drive in my laptop computer it had a disc drive. It was a simple upgrade for a fairly cheap price. My computer boots up really fast now and I have a ton more storage. This drive is also silent unlike the old disc drive

This is big bang for the buck. It works as promised. There were no issues. I had it running in 30 mins. Flawless. Pros: 1. Works as promised. 2. Comes with free Software called ECHO 3. You can download this software from SP website. The key for this is printed on a sticker on the back of the SSD device. People have used it successfully. I have no idea how it is. I used Macrium Reflect to clone. Just wanted to document here that it comes with a free software for cloning. 3. Results are fantastic. I moved from 85/63 to 510/467 MBPS ! Well most most SSDs give that. Just documenting here that it delivered advertised speed. It could give more may be, but I have a small capacity machine. 4. Look and feel is solid. It is of no value anyway. 5. Price point is excellent. I got 512GB for $57. You would get Samsung 256GB for this price as of Jan/2019. Cons: None so far. Reliability - I have to wait and watch. Other thoughts: 1. SSD Management software is available for free download. But my antivirus stopped it saying unsafe. Read on reviews that it contains TROJAN. So I would not recommend it. You can install something free like Crystal Disk Mark but it would not monitor SMART and other things. It is better to be safe than sorry. However I appreciate them offering something for this price range. 2. I had tried Samsung Data Migration and Macrium Reflect earlier on a Samsug EVO SSD 256GB. It never worked, I had to return it. This one was very easy, it was a breeze. And costs 1/2 the money you would pay for Samsung brand. I think Samsung is just brand marketing. There is nothing much. 3. I need 2TB-4TB SSDs for NAS. I would wait for sometime for prices to fall. I would recommend this product.

This is a great Boot SSD for linux and custom NAS systems. Just like any brand I've got maybe one bad drive, but the team over at Silivon Power handled it fast an efficient!!! I highly recommend this brand for any project, like I said I have several of these in different NAS Systems and Laptops

I bought this Silicon Power solid state hard drive to use in an old HP TouchSmart 600 all-in-one that I bought back in 2011. The short story is that I was able to get it work. However, it was not a straightforward as will other brands. As I mentioned, I bought this computer in 2011. It had Windows 7 on it. In 2021, the hard drive was about to die, so I replaced it with a modern solid state hard drive (Samsung brand). Because the newer drives are smaller than the one that came with the computer, I used a 2.5" to 3.5" caddy to hold it. I installed Windows 10. I just followed the install wizard and everything went smoothly. Last week, the power went out and my computer wouldn't boot up. Everything (including the hard drive) passed the checks, but it was super, super slow. I tried to run restores from USB and DVD. They would kind of run, but so so slow, I was unable to troubleshoot. I also tried to install Windows again, but it failed each time. I decided to buy the same Samsung HDD thinking it would be cheaper now (3 years later) but it was actually $10 more. There was a suggestion for the Silicon Power brand (same size and everything) and it was half the price. I have 5 or 6 USB sticks from Silicon Power and I like them, so I bought this one instead. It was just as easy to install into the computer, but the Windows installation did not work. The wizard would not allow me to choose any partition. They were all GPT (and needed to be MBR). I googled and read about some fixes and then watched a couple videos. Basically I had to pull up the command prompt (shift F10) then enter disk partition mode (diskpart), list, then select the disk, clean it, and then convert to mbr. Once this was done, then I refreshed the wizard and it allowed me to choose a partition. And then Windows 10 installed without an issue. I did not have to do any of this when installing Windows 10 on the Samsung hard drive (same computer) three years ago. The issue for this Silicon Power hard drive is that it came as GPT (not MBR) and it was already partitioned (4 partitions). I don't know if this is how all of them come. Maybe this was a used hard drive, returned, and then resold (without reformatting it). I am not sure. But it seems odd that it would come with 4 partitions. The drive is working fine. I am typing this on that computer right now. So I would give the hard drive 5 stars, if not for the way it came (which required extra time to research and stuff). I believe that could be an issue for many people. note: I wrote this review a long time ago, but it appear I never clicked the submit button, so submitting it now.

I bought two of these years ago and have had no issues with them. Just upgraded my sons board to a Gigabyte Z790 EAGLE AX. His existing Samsung 2TB SSD would not be recognized by the board or Windows 11. I tried my backup SSD also a Samsung, nothing. So, I bought him one of these and had no issues.

I got this drive after my main 128GB SSD started failing, had to get a budget option and my buddy recommended this brand to me. He's been buying from them for 4 years now (2 nvmes and a few ssds) and is very happy with them, like to boast their speeds in our discord. Decided to get this as a replacement. Shipping was quicker then expected, but Amazon has a thing for over-calculating shipping times, at least on my end. Went straight to installing it into my PC. Preforms great after nearly a month of using, already threw The Division 2, Apex Legends, Rust, and a few others on it. It runs perfectly. The first CrystalDiskMark (orange backround) was taken on 2020-Aug-14, after I got Windows 10 Pro installed/fully updated. Great reads, great writes. The second CrystalDiskMark (black backround) was taken as of writing this review on 2020-Sep-4. Nothing was running but a single Firefox tab where I am currently writing this review. Third CrystalDiskMark (white background) was taken before editing this review on 2023-Oct-9 Rebooting the PC yields a roughly 40 second boot time, from clicking restart to logging into Windows. Your experience may vary. Overall, I can highly recommend this drive, or any of Silicon Power's other drives for those who need a cheap yet reliable SSD. I was on a very tight budget when I got this and I am very satisfied with the results. Edit 2023-Oct-9: The drive is still going strong as my main drive. I accidentally ripped off the plastic L that the SATA data pins are supported by (thank you locking SATA cable connectors, very cool) but I just carefully shoved them back into the cable and secured it with a copious amount of electrical tape, and it's been working fine like that for around 2 years. I've uploaded a new CrystalDiskMark screenshot to compare with other results.

It's been 3 months since I installed this 4tb ssd into my brand new pc. It has failed. :( I shut down, unplugged everything, and unplugged all 4 ssd's. Plugged back in and everything turned back on, and voila! The drive is seen again! Yay! Tried playing a game from the drive, and the game crashes everytime. Alright, restart PC, drive is gone. Noooo. Okay, restart into bios, drive is not detected again. Ordered new sata cables, didn't work. Since it's the weekend silicon power won't help until Monday.😔 2 stars until something is done. Edit: started RMA replacement. Edit: Finally received the new SSD. Once I actually got it shipped out it only took a few days to receive. 👍 Being in California is a huge plus. Thanks! Hopefully lasts this time, Would buy again.

All is ok

Excelente ssd, aún despues de 7 años lo tengo y funciona de maravilla.

Have had this for a few years now working very hard & is still working well would buy this again

it's a mess - it keeps disconnecting whenever I am editing a video on my computer. I have another ssd drive and no problem at all. it's written 3 years warranty: hope it's true..trying to contact seller now

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.
