  • Great for Micro PC Upgrade
Capacity: 1TB
I recently installed the Fikwot FX991 M.2 SSD 1TB NVMe SSD in my micro PC, and the performance has been nothing short of exceptional. The installation process was straightforward, and the drive fit perfectly in the compact setup. The read speeds of up to 7100MB/s and write speeds of up to 6100MB/s have drastically improved the overall responsiveness of my system. Boot times are almost instantaneous, applications load incredibly fast, and multitasking feels seamless. Even with heavy workloads, the SSD maintains high performance without any noticeable slowdowns. The thermal management is impressive too. Despite the limited airflow in my micro PC, the drive stays cool, thanks to the built-in heat dissipation features. This ensures consistent performance even during extended use. For anyone looking to boost their micro PC’s performance, the Fikwot FX991 M.2 SSD offers excellent value. Its speed, reliability, and ease of installation make it a top choice for enhancing any compact system’s capabilities. ... show more

  • Good ssd!

This works great in my PS5 I bought the 4 tb version and now have more space then I’ll probably ever need! Installation was straightforward and easy. I’m very happy with the product and it was a great price as well. I have had this ssd installed for awhile now and it’s working well and doesn’t seem to have any overheating issues, still very happy ... show more

  • Legit
Capacity: 2TB
Speeds are great, no issues whatsoever, legit product. Also, my cpu only supports pcie 3.0, so this is running at pcie 3.0 speeds. The only thing that’s lower than other speed tests I see online of this specific model is the very largest file transfer of crystaldiskmark, this caps at about 3200 MB/s which is basically fully saturating the pcie 3.0 interface, however for smaller files this is just as fast as running in pcie 4.0. I didn’t upload the screenshot of crystaldiskmark cause people will think that’s its full speed, but basically I’m getting around 3000 MB/s for every test except random4k, which is 52 read and 145 write, which is very good for pcie3.0 I will note this is a QLC drive, which is a newer technology but theoretically is less robust than lower layered drives. Basically for every cell of storage you have 4 “layers” of bit storage, so while an SLC drive will have one layer that is just two voltage levels to record data, this has 4 levels of voltage measurements, that means any degradation or slightly off with the voltages and you’ll lose storage, however to actually “burn out” a cell, you’d need to basically be using it full time every day for like 10 years to even come close to the theoretical wear required to degrade them enough to become unusable. So, I think I’ll save the money and in 10 years when this tech is probably going to be practically obsolete anyways just buy another one instead of worrying about that. ... show more

  • Works Great However...
Capacity: 4TB
So the unit works great in PlayStation 5 however just understand that it's not 7,300 Mbps it's only 6,000 Mbps for reading as that is what PlayStation is identifying it as. With that said the quality is great the space is truly 4TB which is fantastic!, unlike other brands where they cheat you on a few gigabytes. In terms of gameplay the PlayStation works perfectly fine the games work perfectly fine there is no lag there's no problems whatsoever. I do recommend this product. I only gave it a 4 star rating because the company is not telling the truth with regards to the read speed. ... show more

  • Well I'll be darned!
Capacity: 2TB
I got me 2 of these gen 4 nvme SSDs. a 1tb and a 2tb. Windows detected them both right out of the box. The 1tb took a clone of my old boot SSD just fine, and booted up just fine. The 2tb that holds all my games or misc items also works fine. Thankfully the speeds are as advertised! I was a tad iffy in these guys. As I had never heard of this brand before. But it was worth the gamble. These are some good SSDs I paid 100 for the 2tb on a deal. And 60 bucks for the 1tb. If you see these guys at that kind of deal. I'd definitely pick up some. My only complaint is that both SSDs smelt like they came out of a chemical plant. ... show more
