- Storage Capacity: 4000 gigabytes (Measured in megabytes (MB), gigabytes (GB) and terabytes (TB), this is the amount available for storing files, music, movies, photos and more. The total includes the capacity of the hard disk drive and solid state drive if both are included on the computer.)
- Storage Drive Type: SSD (Traditional, mechanical hard disk drives are the most common type of storage because they're relatively inexpensive and offer huge capacities. However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
- Maximum Read Speed: 7300 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)

High end nvme for gaming needs
Excellent price for a high end nvme. I got this for my gaming laptop and it performed well. Specs is right up there with the best of the best. I was also able to get it during the sale and got it for pretty low price right before the new year. Prices for ssd are excepted to drop, but for now I should be good for plenty of games on my gaming laptop. Speed is very fast. See picture of the crystalmark. Definitely not the fastest at sequential, but the IOPs is out of this world and that is what really matters when you are doing a lot of small random files. I highly recommend this for anyone who wants the best right now for a reasonable price. My only gripe is this is a 2 sided nvme meaning there are flash chips on both sides of the board. This might not be a big issue for some but for me, it made the chip a bit chunky. I compensated on my laptop by not screwing it too tightly and use light threadlocker to prevent the screw from coming loose.

Will speed your system up more than anything else.
Okay, there is not much to review. Just pop them into your Gen 4 slot (Gen 3 will work but be slower) and away you go. It is super easy and if you have to force it, it may not be the right type. These things are rockets even compared to your SATA connected SSDs. It made more of a difference in speed on my system than did 64GB of RAM, or a top of the line Intel I9. This is the best upgrade you can put in your system as hard drives are a choke point for data. I recommend a small drive for your OS drive. 500GB will suffice in most cases even if you have a lot of apps but I went with a 1TB because that was the smallest I could get. I then put in two 4TB drives for DATA storage. The reason you want to keep the OS drive small is so you can make backups on the DATA drive. You can partition the large one down for the OS drive but be careful restoring the OS. If your system supports Gen 4 or Gen 3 these are a great option for speed!
