    • Excellent SSD, but DOA. Great Amazon return
Capacity: 8TB Style: SSD
This is the second time I've placed this order. The first time, it was damaged in the US, and Amazon had to cancel the shipment to Ecuador. I bought it again on June 1st (for the second time), but unfortunately, the SSD arrived with controller issues, and I couldn't initialize it. It was practically useless. I needed it urgently for music production work, to store libraries since my SanDisk Extreme is full. However, it wasn't all bad. Amazon, for their part, provided incredible service, and the return was very quick. Amazon was excellent, and I'm truly grateful. I plan to buy another unit (third time's the charm), and I hope it arrives perfect this time. I'll wait for Prime Day. They covered my shipping costs. Thank you, Amazon. I will buy from you again. For a moment, I even thought I would lose my $700. I was super distressed, really. Always be honest with the platform, and you will always have a good experience. ... show more

    • Easily upgraded the storage on my MSI Pulse gaming laptop.
Capacity: 8TB Style: SSD
This drive works perfectly in my gaming laptop! For reference, I installed it into an MSI Pulse 15 B13V. I did ultimately have to clone the current drive to this one via connecting a USB adapter as I ran into some problems reinstalling Windows (unrelated to this drive). Once I cloned the old drive via DiskGenius, it was plug and play. So as long as you know how to open up your laptop and swap out SSDs, you are golden. ... show more

    • Perhaps premature, but installed fine this morning and I will likely forget about it...
Capacity: 2TB Style: SSD
These are commodities these days. I'm sure there's some nuance between the brands, and some reports of issues on the Samsung 990 series led me to this one instead. Would it likely have been an issue? Nah, prob not, given the tens of thousands of reviews on each. Installed fine, detected fine, and formatted in about a second. Unexciting, but required upgrade (when you run out of space). ... show more

    • No regrets has room for tons of games.
Capacity: 4TB Style: SSD w/ Heatsink
Absolutely worth the money, I was scared to take my new ps5 apart, then I watched a video on utube saw how easy it was to install and got it on prime day on sale. Took literally 10 minutes from start to finish. Son bought one and had his installed without any problems what so ever. Great Buy.

Got for my fiancée for his birthday and he loved it. I don’t know a lot about computers but he chose this and seems really happy with it, and it seems to be a good value.

    • Bought it for my son's ps5
Capacity: 2TB Style: SSD w/ Heatsink
Why did you pick this product vs others?: Literally took 2 minutes to install, no firmware update needed. This definitely cheaper than the one listed as "ps5 official hd" and it's by the same company

    • Insane Speed & Extra Space – A Must-Have for PS5!
Capacity: 1TB Style: SSD w/ Heatsink
I recently purchased the WD_BLACK 1TB SN850X NVMe SSD with Heatsink, and I couldn’t be happier. Here’s my detailed review: Features & My Experience Blazing-Fast Speeds (Up to 7,300 MB/s): Claim: Ridiculously short load times and top-tier performance. Reality: This SSD delivers insanely fast speeds. My PS5 boots up quicker, and load times in games are almost nonexistent. Everything feels smooth and instant—just how next-gen gaming should be. More Storage, More Games: Claim: Up to 8TB capacity means you can download more games without deleting your favorites. Reality: I got the 1TB version, and it’s a game-changer. No more constantly deleting and redownloading games. Now, I can keep my library ready to play anytime. Built-In Heatsink for Peak Performance: Claim: Helps maintain speed during intense gaming sessions. Reality: My PS5 recognizes it immediately, and the built-in heatsink keeps it running cool even after hours of gaming. No overheating issues, just top performance. WD_BLACK Dashboard (Windows Only): Claim: Monitors drive health and allows RGB customization (heatsink versions only). Reality: While this feature isn’t usable on PS5, it’s great if you’re using it on a gaming PC. Still, performance on PS5 is flawless, which is all I needed. Advanced Gaming Features: Claim: Predictive Loading, Overhead Balancing, and Adaptive Thermal Management improve efficiency. Reality: While these features work in the background, what I notice the most is how fast and responsive my system feels. Games launch almost instantly, and there are no hiccups. Final Thoughts This WD_BLACK SN850X SSD is an absolute must-have if you want faster load times, extra storage, and top-tier performance for your PS5 or PC. Installation was quick and easy, and the difference in speed is noticeable immediately. If you’re looking to upgrade your gaming experience, this SSD is worth every penny! ... show more
