When used in a system with HMB, the speed differences only really show up when reading and writing large amounts of files.
HMB is just system memory and is inherently slower than onboard cache. This also means that there's less system memory for doing other things.
HMB is not guaranteed, and most drives use it primarily for caching the mapping tables, not write data. This means lower write efficiency.
While HMB is better than nothing, onboard DRAM cache is much better than HMB.

Was it much cheaper previously? I'm tempted but if it's cheaper, I'll wait
Anyone who thumb me down, be helpful instead of being a dbag.

I never knew this was a thing to look out for when buying an SSD.
The Lexar NM790 does NOT have DRAM.
The closest Lexar model with DRAM is the NM800 PRO.

From what posters have said on here, it's best to buy a drive with a heatsink as opposed to buying a heatsink separately, to protect against potential heat issues.

Techpowerup's review of the MP600 Elite (identical hardware) shows real world performance near that of many current gen DRAM drives and even outperforming older DRAM drives. Unless you're connecting it to a system not using NVMe (i.e. USB enclosure) or very old NVMe specs, you will have HMB.
plan on using this in a external case and doing an weekly time machine backup
this is a gen2
So that should keep its heat potential down, right?

You don't need DRAM SSDs for gaming and other everyday tasks. Sure, DRAM-less SSDs are lesser and have shorter lifespans, but if all you do is game etc., it will take you many years before your SSD wears out. And, when it does, it just slows down to the point where you'll replace it well before it becomes read-only.
Either way, with normal use, you will most likely upgrade your storage to something bigger or next-gen tech before your SSD wears out.
I recently had to replace a 10-year-old SATA SSD because it wasn't big enough. Only after the upgrade did I notice that it had slowed down due to wear. It was still working fine but had gotten slow, which I noticed because the replacement SSD was snappier. On the other hand, I have another 10yo SSD (same make and model) that still performs close to when I bought it.
