well apprently it has real dram: DRAM Cache: Nanya 128MB DDR3
but gen 3 is kind of…
Depending on what your board supports but yeah
but gen 3 is kind of…
Disagree, unless you actually need Gen 4 speeds, it won't make a difference
In fact, I would recommend a good quality gen 3 over a budget gen 4 any day
@Willy Bargin: See my test result for NM790 (without heatsink version) vs Tom's Hardware's MP34. Honestly, the performance difference isn't big enough to justify the $16 heatsink version of NM790. But, the non heatsink version is only $6 more. I fear that once you've seen the results, you will most likely lean towards NM790.
While I think for $6 more, it might be better to get NM790. As I mentioned in one of the earlier NM790 deals, as soon as I own an NM790 (which I now do), my advice to get NM790 can be biased. The reason I suggest NM790 is that it is known to be TLC, but I cannot be certain MP34 is still TLC (based on TBW, it should, but when Centrecom sold me a newer batch of an SSD which I thought to be TLC (coz. I bought an older batch from Centrecom, and it was TLC), even the SSD maker did not adjust the TBW and the new batch turned out to be QLC).
However, $/GB, neither SSD is all time best for TLC SSDs.
@Willy Bargin: If minimum power usage for desktop or laptop is a key factor, then it is simple, don't get either. Frankly, I find SSD power usage on desktop being a key factor perplexing. Surely on a desktop, SSD power usage is tiny compared to other components. Laptops, AnandTech did a test, at idle, most SSDs have roughly the same power consumption. Also, thinking saving SSD power usage will extend laptop battery life by a lot is wishful thinking. The display draws more power.
Produce less heat, if that is a big deal to you, get the heat sink version of NM790. If you find yourself thinking a lot about getting an SSD, then the answer is simple, you don't need one and the price is not low enough.
@AEKaBeer: yea i hate buying something then find a better+cheaper one 1 day later . part of the reason i use the 7/eleven app to luck in my fuel :)
It's not as clear cut. I am only able to test NM790 1TB on a PCIe gen 3 x4 system. Also, Tom's Hardware's result is on MP34 512GB version (so MP34's result won't be as good and NM790 result will be slightly better than 4TB in PCIe gen 3 x4.
PCIe gen 3 x4 Test (Note: not 4TB models and different sizes (not fair comparison)):
| Team Group MP34 512GB | Lexar NM790 1TB | |
|---|---|---|
| Sequential Read Q8T1 | 3472 MB/s | 3726 MB/s |
| Sequential Read Q1T1 | 2903 MB/s | 3230 MB/s |
| Random Read 4K Q1T1 | 13187 IOPs | 16875 IOPs |
| Sequential Write Q8T1 | 2103 MB/s | 3493 MB/s |
| Sequential Write Q1T1 | 1917 MB/s | 3104 MB/s |
| Random Write 4K Q1T1 | 43162 IOPs | 40354 IOPs |
Note: I do not recommend NM790 for NAS usage because DRAMless SSDs generally don't perform well in consistency tests. NM790 4TB's TBW is actually higher than MP34 4TB, but for NAS, it is not just TBW. NM790's large dynamic SLC cache is another plus. NM790 is not easy to beat unfortunately. NM790's test results in PCIe gen 4 x4 mode is most certainly even better.
My NM790 1TB PCIe gen 3 result:
NM790 1TB, PCIe gen 3 x4, direct to CPU m.2 slot Crystal DiskMark Results
I only saved the MB/s screenshot. I do have the data for IOPs saved in a text file so I was still able to compare with Tom's result for MP34.
I don't need it.

Thanks OP. Time to replace one of my Kingston A2000 drives.
2400 tbw, think this would do well in nas?
following
Why not?
3 in a raidZ1 would be pretty sweet.
For a low user count workload you could probably all but disable your ARC with ssd storage :)
I'm not really thinking about talking raid or zfs, more so as a single drive in a nas or as a VM datastore. from what I've read, zfs kills the nvme drives + kills performance.
Vm datastore would be fine.
The rest is a non-event, since most home users will have at absolute best 10GbE lan connections, and even a spinning disk array can saturate it.
Zfs doesnt do anything bad to ssd's.
They wont be "amazing" because of the synchronous nature of the zfs journal, and you'd be best to disable atime on your files (who uses that?!) But even with the worst possible config, you'll saturate your LAN before your disks.
@MasterScythe: Thinking about pulling the trigger, was looking at the 2tb wd red sn700 with 2500tbw, but this is very tempting
What Nas supports nvme or are you talking a DIY Nas?
I have a few in a NAS, working well so far.
I have one. Paid $400 about a year ago.
Great drive for my steam and epic games libraries.
Buy first think later - Ozbargain sprit!
Am waiting for @netsurfer to answer this and his opinion on the drive, until then do nothing. :))
LOL, my "subjective" view on this (note: it's subjective so it is biased).
^That's what i'm talkin' about! :)))
I will stick to my plan, the Lexar NM790 (non heatsink version) picking one up tomorrow. Needed a 4TB for a while now.
Go team netsurfer!
I couldn't decide NM790 or MX500 (M.2 or sata) here but think the NM790 is the way to go.
Both are good.
NM790 is faster Gen 4 and has single-sided PCB
MP34 is slower Gen 3 and double-sided PCB (so might not fit with laptops)
Both should be TLC
NM790 lacks DRAM while MP34 has 128MB - but DRAM is no longer really necessary for modern NVMe SSDs, especially if using it for games/storage.
Personally I'd get which ever is cheaper.
It's easy if the margin is $100
But at $6 difference… difficult to discern… I think it comes down to device compatibility like you said. 790 seems like definite laptop/PS5 drive. MP34 seems like good archive drive, good for older desktop machines. May run cooler as well.
The NM790 does seem to have some major haters though due to bad Linux support. It may also be better to get the heatsink version for a desktop which might bring the margin up enough to encourage buying the 34.
My desktop doesn’t have usb C or a spare Nvme slot (b450), so I’d like to use this in an external enclosure setup.
Any recommendations on a fast enclosure and usb c pcie expansion card? Hoping to get some decent speed out of it without spending a fortune
Best if you just use a pci-e adapter card
This is just for example, for an x4 slot
https://www.ebay.com.au/itm/195934545828.
You also got to be check since on B450 some slots are shared with the secondary m.2 slot. Meaning you can't use both at the same time
Thanks both; was hoping for the portability to my laptop too
Good call-out on the board; will double check the pcie and Nvme ports aren’t sharing resources
B450, the secondary NVMe slot is quite likely PCIe gen 2 x4. Also, your PCIe x4 (logically x4, physically x16) slot is likely gen 2. Good point on checking whether it is shared with the secondary m.2 slot (i.e. can only run one).
You could technically get the x1 version of the card, but at PCIe gen 2 x1, it is going to run at best a bit better than SATA. Also, if it is x1 card you are getting, I would consider AliExpress and buy a cheap one. You don't really need a heatsink if you run the NVMe SSD in x1 mode.
If you've got a spare x4 PCIe slot you can get a $20 adapter to put it in there.
This is better than the Lexar NM790 as it's guaranteed TLC and has DRAM? Wanting to store my large game library on this so it will get pretty full fast. I want to be able to maintain good load times.
Those who are wondering if you will get QLC if you buy this, the QLC version is called the MP34Q.
Also, if it is double sided, then it is more likely TLC, as if it was QLC, it would require fewer NAND chips!
The 128MB of DRAM is tiny. I use it as a storage drive, and it works fine. It does slow down a bit with Windows loading the file list etc when you use up 3.5TB of the 4TB, but otherwise, it is worth the low price.
That’s a decent TBW even considering it’s 4TB!
