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 ### ⭐⭐⭐⭐⭐ Amazing budget SSD, reliable after 3+ continuous years of use. *by on Reviewed in the United States September 4, 2020* 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-9Rebooting 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. ### ⭐⭐⭐⭐⭐ Worked far better than expected *by on Reviewed in the United States November 16, 2019* 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! ## Frequently Bought Together - Silicon Power 256GB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5" Internal Solid State Drive SU256GBSS3A55S25AH - Silicon Power 256GB NVMe M.2 PCIe Gen3x4 2280 SSD (SP256GBP34A60M28) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/597246979-silicon-power-256gb-ssd-3d-nand-a55-slc-cache-performance](https://www.desertcart.ec/products/597246979-silicon-power-256gb-ssd-3d-nand-a55-slc-cache-performance) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-07*
