990 PRO SSD 4TB PCIe 4.0 M.2 2280 Internal Solid State Hard Drive, Seq. Read Speeds Up to 7,450 MB/s for High End Computing, Gaming, and Heavy Duty Workstations, MZ-V9P4T0B/AM

I am using two of these 1TB drives in a custom NAS box I put together running TrueNAS. I have two 12TB HDD drives, two slower SSDs, and two of these great Samsung 1TB NVMe drives. While the majority of my backups are on the mirrored HDD drives, and the TrueNAS boot drives are the SSDs, I use these two Samsung NVMes as a high-performance NVME pool for storing apps, containers, metadata, VMs, databases, and PLEX metadata. This is ideal because the ZFS mirror offers redundancy for critical app data, low latency and high IOPS making it a great place for TrueNAS apps and datasets. These drives are the biggest real-world performance area of my NAS so I use it where speed matters most. The TrueNAS OS and temp jobs/work stay on the SSDs so they don't wear out these NVMes quickly. These drives are nice and fast for PCIe 4.0. They also were a great price at the time because of holiday pricing and they were on backorder for a bit, which caused the price to drop for a week, too. So the value couldn't be beat at the time. Samsung drives like these have never failed me, and some of my M.2 drives get quite a workout on my main desktop build! The only thing I would recommend with these drives is using a third-party heatsink on them that has a fan on it. It keeps these drives nice and cool during high loads. Without them, you run the risk of overheating and heat-related speed throttling, causing your drives to slow down while hot. So keep these drive cool by slapping a $20 M.2 heatsink+fan on there and never worry again! These drives were perfect for my new NAS, or for your next desktop PC drive replacement! They work great and are trouble-free for me so far. I will update if I ever run into any problems with them.

Used this new drive as a larger replacement for my C:/ drive (OS drive) in my Dell XPS 8930 desktop system. So far, this thing works great and is amazingly fast. My system originally came with a 256GB PCIe NVMe M.2 SSD drive. But, I was very close to the max limit on that drive and I was having trouble finding anything more to move to my secondary data drive. I also didn't really relish the idea of having to do a fresh windows 11 install and having to reload all my apps, data and everything else. I keep my system throughly updated and cleaned up, so I wasn't dealing with an old, bloated, slow install. I went with Samsung for this new SSD, for two reasons. First, I've bought Samsung drives before and was always impressed. But, most of all, because I was familiar with the Samsung Magician software that you can download free to do the data migration (cloning), as well as other ongoing drive maintenance. This free software will only allow you to transfer to a Samsung drive, so it's a no-go if you buy a different brand of drive. As expected, the Samsung Magician software is very good (now in Version 9.0) and it made the cloning of my old C: drive an easy and quick job. My old drive had nearly 220GB of data to be migrated to my new drive and it all happened in a little more than an hour. It copies and transfers every single bit of data from the original drive. Once it says the transfer has completed, you just shut it all down, transfer the new drive into your original C: drive socket and power back up. Everything is exactly the same as it was when you started. I had to use a UGREEN NVMe M.2 enclosure plugged into my computer through a USB port for the cloning operation, as my Dell desktop computer only has one NVMe M.2 slot. That was also purchased through Amazon for less than $20. So far, this new SSD drive is super fast and hasn't missed a beat since it was powered up. I highly recommend Samsung drives. One last note.......if you have questions or problems installing your new SSB, Samsung has a great customer service telephone help desk. Within 5 minutes of placing my call, I was talking to a very knowledgable computer expert that immediately answered my questions, made a couple of good suggestions and had me all taken care of. And, believe it or not, this guy sounded US based and was very easy to understand. All together, my problems were resolved in less than 10 minutes total, including a short wait to be routed to the correct product specialist. Way to go Samsung!

Fast speeds reliable- basically no data loss! And very easy to install! Samsung's ssd is always my go-to!

Really blistering fast SSD. I do software development and work with lots of large databases. The 990 PRO shows up and delivers with very low latency and excellent speeds. It's easy to find benchmarks online, from places who can better measure and compare so I'm going to do that here. One aspect I like is the Samsung Magician software, as well as the software they'll give you to transfer data to your new drive. The Magician software is super easy to use and helps you keeping an eye on the SSD, lets you know what temperature it's running at and if the SMART values are OK. It's easy to use and read, no need to be an expert. Let's you update the SSD firmware if there's a new version. It's all-in-one and works extremely well; I can only speak for Windows use here, not Linux or other OS. There have been very few firmware updates.. I remember one when the drive just came to market and there was an issue about longevity rating but that has been fixed long ago. A new drive will already have that fix on them. Just a sturdy product with no surprises. I've ran the 2TB version since it came to market, and added the 4TB one a few months ago. Nothing ever went wrong, and that's why I mostly buy Samsung SSDs.

My expensive workhorse laptop was running very low on the primary drive capacity, needed bigger SSD and after extensive search and reviewing reviews I settled on this one. I bought SSK M.2 NVME SATA SSD Enclosure along with, and the drive came with the cloning sofware. First timer to do this but the whole operation went very smooth, no glitchs. Noticed the the first 99% of the operation went fast but to go to 100% took a bit longer time likely to finsis data and close the cloning operation so be patient for the last 1%. It is faster the the older one, doe not heat up although I did not buy the heat sink with it, Does not disappoint and worth every penny

Samsung's 990 PRO storage is great doing what you ask of it. The speed of the storage is more than I need, and it holds all of the terabytes (4 of them). I used this is my boot drive and that likely helps the rapid boot times, and it hasn't had any connectivity issues in the enclosure. Pros: -Samsung performance, lifespan, and quality -Fast -Huge amount of space (4TB) Cons: -Price hurts a little I like it, I use it, it's invisible in that works so well I don't care about it.

This Samsung 990 PRO 2TB NVMe SSD turned out to be one of those upgrades that quietly changes everything about how the PC feels. The small M.2 stick takes up almost no space on the motherboard, but it adds a huge amount of fast storage that makes the whole system feel cleaner and more modern. For size and storage, the 2TB capacity is a sweet spot. It is small and slim enough to disappear under a heatsink or alongside a big GPU, yet spacious enough to hold Windows, a big game library, and work files without constantly worrying about what to uninstall next. It feels like finally having “breathing room” on the main drive instead of constantly managing space. The design is simple and professional, with no unnecessary bulk or gimmicks—just a clean-looking drive that fits right into any build, whether flashy RGB or a more minimal setup. Day to day, the quality and performance really stand out: the PC boots quickly, games and apps launch almost instantly, and large file transfers finish much faster than before. It feels reliable, fast, and well built, and easily deserves a full five stars.

I'm no fanboy but when it comes to storage, I love Samsung. It used to be Western Digital when I was young but something has happened to them over the years. This is one of their better drives. They do have newer ones targeting AI but unless you're decking out your machine for LLM and have hundreds of gigs of RAM to support it, this will suffice for basically everything except maybe the actual amount of space. So, buy a couple or look for an 8TB. These drives work well. I have a lower model in my desktop by mistake. Honestly though it's so fast compared to "faster" models from other brands, I can't tell I bought the wrong one. This one is in one of my laptops. The laptop mount wasn't correct so I had to make a rubber washer for UNDER the SSD which is unusual. Otherwise it mounted fine. Not the drive's fault but the computer. It was recognized perfectly but one note: If your computer has Intel RST/VMD and you intend to use linux, you may need to disable it. This may prevent Windows from booting until re-enabled. Luckily for me, I just deleted Windows. Problem solved. This is a side-note for those of you purchasing these for dual-boot to hopefully save you some headache. Anyway ... 4tb ... super fast .. I have it luks encrypted, full-bore. You simply cannot tell. That's why I love these drives. I work on sensitive projects. Some legal. Some health. Some security. Etc. I run full disk encryption on my project storage and active machines with different keys each obviously and other security measures we won't get into but with this sort of NVME the performance loss is absolutely negligible. For example the "AI" nvme is absolutely not needed in my case. I actually do a lot of AI code. Financial predictions to massive patterns that I can't explain here without breaching contract but the point is, the drives are never maxed out even while fully encrypted. My GPU, NPU or CPU always bottlenecks first. The same with Video Games. Even VR games. Basically, there are few cases where this drive will not suffice. You'll know if you truly need better. If you aren't sure then, this drive will probably be perfect but it doesn't hurt to double-check.
