When I'm asked to recommend an SSD, either as a replacement for a boot drive or something to just store games, I generally only ask a few questions first: What's your budget, and do you need to write lots of big files all the time to the drive?
The former will determine what capacity one can get and if it's around the $140 mark, then you're looking at 2 TB of storage. To be honest, that's something I recommend anyway as even 1 TB can fill up very quickly with some of the latest games.
However, the latter is about determining whether the SSD needs to have a DRAM chip. Without going into a long story about how NAND flash storage works, DRAM is only important if you want to have the best performance while writing lots of big files to the drive. I'm not talking about just a few gigabytes here and there, I'm talking hundreds and hundreds, over and over.
In the old days of SSDs, DRAM was required to store the map of where all the data is located on the drive but modern SSDs all support something called Host Memory Buffer (HMB), which stores the map in a small part of your PC's system memory. It's still a little quicker to have it in some RAM local to the SSD but in general, it's now just used to support protracted and heavy writes.
And it's the latter question you need to ask yourself when choosing between these two great SSD deals. The first one is from Nextorage (a storage company that started life as a division of Sony) and is a brilliant drive. We've reviewed the DRAM-equipped version (NEM-PA) and it's blisteringly quick; thanks to the beefy heatsink, it also runs very cool.
This DRAM-less NEM-PAB version is just as speedy but won't be able to sustain that performance when being worked really hard for lengthy periods.
If that scenario is important to you, then for just a few dollars more, the WD Black SN850X is the one to go for. It's been our top choice as the best gaming SSD for a long time and for very good reasons. It's ridiculously fast, runs cool (though that will depend on your motherboard's SSD heatsink), and sucks up pretty much any data writing load you care to throw at it.
My main PC has four of them (one for boot and primary apps, another for development stuff, one for games, and a final one for documents). A tad excessive perhaps but the SN850X is an exceptionally good SSD and I don't regret spending the money one bit.
Both SSDs have been cheaper in the past but at the moment, SSD prices are generally on the higher side as flash manufacturers have been lowering production to improve profit margins. Fortunately, no matter whether you buy the Nextorage NEM-PAB or the WD Black SN850X, you'll have a brilliant SSD in your gaming PC and it'll serve you well for many years to come.
