This is a genuine Samsung 870 EVO SATA SSD, and it performs exactly as expected. Installation was quick and easy, and the drive was recognized immediately. Performance is excellent for a 2.5" SATA SSD, with fast boot times, smooth application launches, and consistent speeds. Samsung's build quality and reliability really show here. It's an excellent upgrade for older desktops or laptops and a solid choice for anyone looking to replace a traditional hard drive or a lower-end SSD. Overall, a dependable, high-quality SSD that delivers the performance Samsung is known for. ... show more

I got this Samsung 500gb 2.5" SATA SSD to upgrade from the 512gb HDD in an old HP Pavilion laptop (model HP 15-f233wm). It's a perfect fit and works great. It's made the old device MUCH faster and improved the overall performance immensely. I consider myself a functioning illiterate when it comes to computers. So, when I tell you that this drive was easy to install and get working you can believe it. Once I got the laptop open and ready it was an easy process to swap over the new SSD for the older HDD. With the ongoing phase out of Windows 10 I've decided to better educate myself on computer systems by tinkering around with this older laptop that cannot run the newer system (Windows 11). It was recommended to me that, given the outdated system and limited room for improvement, the best thing I could do to upgrade the old Pavilion was replace the original HDD with a newer SSD to improve overall performance. I was a little nervous as I've never done this type of thing before and I don't really have much tech savvy. I watched a few YouTube videos, ordered this Samsung SSD replacement, and got to work. It was a major improvement. The old laptop runs better than it has in years; faster, quieter, overall better functionality. It's still old and outdated but it works well for basic productivity. BOTTOM LINE: I think this is a great product and a wonderful value. I have no complaints at all and I highly recommend it. ... show more

    • Update: Two (2) years later ... The 870 EVO: The 4TB Unit Is An Excellent Drive. PERIOD.
Capacity: 4TB
Update: Two (2) years later. Upgrading (4) star score to (5) stars. All the 870s in both the 4(T) and 2(T) capacity have performed super-well with no performance issues whatsoever. I will also say the same for the 840s and 850s mentioned below. None of those drives have failed either. Nor have they experienced any performance problems. Still running the same file server with a 500GB 850, (2) 4T 870s and a 4T WD Red (mechanical). The Samsungs are outstanding drives. I routinely use them to backup 60-80 GB "image" files and never a hiccup. The file server is now about ten years old and even with TPM 1.2, I'm still running Windows 11 with all Certificates updated past 2026. There is no reason I can't get another five (5) years off the server and do not expect any trouble from any of my drives, either. While I have read of drives failing upon occasion, deeper research suggests to me that users (operators) were likely running those drives so hard, they got hot - really hot. So I would suggest users try and avoid hammering their drives. That said, I love these drives and will use them as long as there are no SMART issues; none to-date on ANY of my Samsung drives. Simply amazing. And I'm running them on every laptop, worlstatio and file server I own. And I'm running them on all my father's PCs as well. No issues either. ********************************************** Storage costs have been dropping recently and I was able to get my 4T unit for about 5.7 cents per GB. Not bad. Before users run out to buy they should be careful to not buy from questionable sources .. sources offering an unusually low price point. The reason being is they may be trying to off-load older 870 EVOs (02/2022 to 11/2022) with flawed firmware. These drives are in my view essentially junk and should be avoided. The firmware version that appears most readily is "SVT0B6Q". That out of the way, the 870 EVO is a great drive. I'm still running 840s, 850s and 860s and NONE of them have failed. Several purchasers have noted difficulty getting Samsung drives to properly authenticate their serial numbers, register as "genuine" or fully function with Samsung Magician (diagnostics, performance and Rapid Mode). What they may not be informing readers is that they are likely trying to utilize the drive from an either an external drive enclosure or a drive "strapping" device/adapter. The Samsungs (none .. including 840, 850, 860) will not fully register in those circumstances if the adapter's controller is NOT an Intel controller. Micron-based controllers are (e.g.) ubiquitous in any number or adapters or "straps" and Samsung SSDs will not fully register in those devices. That being said, adapters or "straps" are still perfectly fine for formatting (only) the drive. Adapters will (also) be unable to perform "Over-Provisioning". The drive will need to be internally installed to the PC (unless adapter has an Intel controller). Once installed, the drive will fully register and become available for all the Samsung Magician operability options. Later this year, I will be purchasing a second 4T unit to replace the #1 storage drive in my file server. Previously running WD "Red" magnetic drives, the 870 Evo consistently writes at 540 MB per second vrs the WD at 160. Since I don't game, faster backup speeds don't require ultra-high PCIe speeds for large file storage which I routinely do when taking multiple back-up images from the various PCs in the home office. Of note, I've had flawless SSD image performance with both Macrium and Acronis TrueImage (all paid versions) in the past. Other than improved time for large file backups, the SSDs also run about fifteen degrees cooler and use anywhere from 55-80% less power depending on state of use (running vs idle). For those looking to squeeze every year of use from an aging power supply, lower power demand likely translates to longer PSU life. I will eventually retain a single magnetic drive in the server but adding a #2 data storage 4TB 870 Evo makes good sense and will help me realize an additional 5-7 years of server life. In that regard, my goal is to get about twelve years before I do another rebuild. My form factor is mITX for those that wondered. You'll get great service from this drive and the price-point low is enough to get most off the fence for the upgrade. The very best of days to all. ... show more
