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

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

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.

First of all, I have owned and operated a computer business for over 20 years, so I have seen the good and the bad, and, probably just like the rest of you, I read the reviews of items before I buy them. For me as a business owner, I have to be careful what we buy for and sell to our customers, and this drive was just such item we ordered for a customer that needed a new hard drive as theirs had crashed. I ordered it one day and it arrived the following day. Packaging was nothing special and was what was to be expected. Going from a traditional, mechanical drive to an SSD was already a given that it was going to be an improvement, but what we did not expect was just how much of an improvement it would have been for this system. Keep in mind, the system itself was nothing special, decent processor and 8GB of memory. We installed this drive fairly quickly, used a flash drive to install Windows 10 on the system and the installation was rather quick, which caused us a little hesitation at first thinking that something went wrong since most times installation takes considerably longer, but this was done in roughly 10 minutes, if not less? We let things run as they should and the installation was perfect, however, what truly impressed us was the boot time of the system from cold start to full on Windows ready, which was roughly 10 seconds! We thought that might be a fluke, so we shut it down and restarted it from cold start, and the results were the same. Now, as a comparison, we used a similar sized traditional hard drive and performed the same installation on the same computer so that there was no room for error or saying that system A has this processor and system B had this much more memory. Installation took roughly 24 minutes on the traditional drive and boot time was about a minute and a half before you could do anything without the little circle basically telling you to wait. Let me say this, I could care less what the reviews others may provide here are, perhaps they got a bad drive, which happens, or something else happened, I do not know, but, when we see install times cut down to less than half the time and a 10 second boot time, that is impressive, period. Will this drive be perfect for EVERY installation and provide the same results EVERY time? Of course not, conditions vary, experience and skill level of the installer will vary from person to person, and if there is one thing that we have come to realize over the years in this business is that people are far more willing to blame a device than their own user error because that is far easier to explain. If we are at fault and did something that would cause an issue, we own up to it, and yes, we know that devices can fail during installation or you get a bad batch or device, it happens. But, for some people, before blaming the device for a failure, consider looking at the conditions before blaming the device, as there might be a good chance that the failure was due to user error before device error. Would we recommend this drive to others? Absolutely. Will we continue to use and install these drives in other systems? Absolutely. Are these the "magic sauce" that is going to put your system over the top and make everything perfect? No, but these drives will do the job and make you happy you bought them!

This Silicon Power A55 256GB SSD is a solid budget SATA drive for basic use. I used it for a small system/appliance-style setup where I did not need a huge drive, just something faster and more reliable than an old hard drive. Installation was straightforward, and the drive was recognized normally. This is not a high-end workstation SSD, but for operating systems, lightweight servers, older desktops, mini PCs, or general boot-drive use, it is a good value. The 2.5" SATA format is also convenient because it works in a lot of older machines and small systems. For the price, I was satisfied with it.

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 this ssd to make my laptop load things faster, and it did exactly what i bought it for, windows loads a lot faster, with other pleasant side effects like the battery lasting this tiny bit longer, and the laptop being this tiny bit quieter. its got good performance, not only windows loads faster, but games and other programs load faster than on hard drive. for the value of capacity to dollar, this is a good drive. using the ssd as a boot drive for windows 7, 476.94 gb is shown on the drive, not anywhere near the 512 gb on the amazon listing but it was a capacity upgrade from my old 500 gb hard drive, and most other ssds will have this effect too. overall, a great upgrade for any laptop with a spinny drive.

The SP 512GB SSD A55 has been a fantastic upgrade to my system! With 3D NAND technology and SLC cache performance boost, this SSD has significantly improved my computer's boot times and overall responsiveness. Programs load quickly, and file transfers are super fast compared to my old hard drive. Installation was easy—thanks to the SATA III 2.5" format, it fit perfectly into my laptop without any issues. The 7mm slim profile is a nice bonus for compatibility with thinner laptops. Plus, with 512GB of storage, there's plenty of space for my OS, applications, and a good chunk of games or media files. For the price, the performance is top-notch, making this SSD an excellent value. Whether you're upgrading an old system or looking for additional storage, I highly recommend the SP A55 SSD. It’s reliable, fast, and gives a noticeable boost in performance!

1TB for under $50 is a fair price for such a decently spec’d SATA SSD. I used this drive in my user upgradable MacBook Pro with very solid results. It installed without a hiccup and formatted without issues. It is a noticeable improvement over the standard rotating storage included as standard. I don’t know how long this drive will last but I have purchased other SSD’s from the same brand and they are still going strong 4-years and 7-years later. That doesn’t always translate into like performance and/or longevity but based on my previous experiences with this brand and the price of the drive I wasn’t concerned. Fast with plenty of storage space available at a relative bargain.

All is ok

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
