Inexpensive NVME SSD for a laptop

I am purchasing an MSI Titan GT75 and want to add an extra SSD just for one particular game. I use a program called DriveImage XML to restore a backup from a thumb drive to this drive but the data is less than 16GB so it is fine to get a smaller SSD (a 128GB looks to be the smallest they sell these days).

Any good suggestions? Is it important to buy one with a heat sink on it?

Here is one for $49 for a 240GB that seems good, but i have no experience with this brand (XPG):

Here is an HP one for $35.99 for a 120GB but it is slower than the XPG above:

I haven't checked amazon yet, but open to suggestions if someone sees a good deal or a good product. I would like to keep it under $50 if possible.

Review

Obviously it's not the fastest, but it's not bad either, you wouldn't notice the difference other than in synthetic benchmarks as it's still an NVMe SSD afterall

 

The SX8200 is a great NVMe drive, really can't go wrong there. I picked up a 480GB for my XPS for around $70, there are deals to be had on them.

This is likely a stupid question, but why do some SSD's have two keys:


While others have just one key:

 

Not a stupid question at all. M.2 is the form factor of the drive. They can come in different interfaces (NVMe vs SATA). The different keys prevent you from installing a NVMe drive in a SATA only m.2 port.

For any SSD, doesn't matter if it's SATA or NVMe, you want to avoid capacities of less than 240 GB whenever possible. Such drives have much lower write speeds and flash memory endurance, plus their performance will degrade much quicker as they fill up unless you take away even more space for over-provisioning.

XPG is essentially the "gaming" brand for ADATA, and they're a well-established company. If all you need is 240 GB, $49 is a great price.

 

Thanks for your input everyone. I purchased the SX8200
