Silicon Power 256GB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5" Internal Solid State Drive SU256GBSS3A55S25AH

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!

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!

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.

Performance is quite good and predictable for a drive of this price point, much better than some more expensive drives from better known manufacturers. Read speeds are about the theoretical limits of the SATA bus, depending on factors like your file system, file size, etc. of course. Writes are slightly lower in burst, and substantially lower in sustained writes that overrun the SLC. However, I did find that they were able to sustain much faster write speeds than the budget line of a *major* SSD / memory manufacturer. These drives are also rated at almost twice the write durability. So, pretty good value for money. Silicon Power chose to cut cost by forgoing metal in the SSD case, these are plastic, so these drives will not sink heat off very efficiently. However, they do run on the cool side even with this handicap, so long as they're not in an unventilated hotbox of a system, they should be OK. As of these writings, these drives are not in the smartctl database (7.3/5671), so expect reduced telemetry on systems where you don't install their bloatware. It'd be very nice (and go a long way towards their credibility) if Silicon Power made the SMART info for their drives public.

Cloned original hard drive as a backup. worked beautifully!

Be warned, this drive is incredibly slow. After an initial burst of speed, once the SSD's cache is expended, transfer speeds fall off a cliff, quickly going down to about a sustained 25 - 30 MB/sec.... making this several times slower than the smaller TeamGroup 1TB SATA SSD that this Silicon Power SSD was meant to replace as an upgrade in my PC. While I appreciate the higher capacity of the Silicon Power 4TB SATA SSD at an affordable price, I think a physical spinning platter hard drive would give me faster transfer speeds at a cheaper price per terabyte than this SSD. I never thought I would see the day when an SSD would be slower than a 7200 rpm hard drive, but apparently Silicon Power proved me wrong. Now I kind of want to open up the Silicon Power SSD and see if there is just an SD card inside or something, because the speed of this drive is so incredibly slow, I am having a hard time believing that this SSD drive is real.

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.
