no, it utilizes hmb3 caching
from a review
What this drive has that’s generally better than older designs is that it supports HMB 3.0 and Dynamic SLC Caching, enabling it to achieve and sustain high levels of performance using the RAM of the host system and the ability to convert NAND to cache memory dynamically.
For those with plenty of RAM and lots of space free on the drive, it is possible to sustain write speeds for large files without exposing the underlying speed of the MLC NAND on the drives to the user. An added bonus for the drive maker is that this avoids using expensive DRAM to perform the caching, which also consumes additional power.
How can you check if your system supports HMB3? It seems like a good solution for a budget system but so far seems like a gamble to see if my system will run it.
HMB was introduced in NVMe 1.2 which is 7 years old.
It's supported by Win 10/11 and Linux.
I believe if your system fulfills these requirements it's automatically supported.
@McFly: Thanks! Thought it was much newer than that since I've only recently heard of it with these new SSDs.
@Alzori: Using HMB has been around for a few years now. It's been a common technique for DRAMless SSDs. Basically, it takes a small amount of your system RAM (64MB) to compensate for not having a DRAM on the SSD. It does have two disadvantages:
DRAMless SSDs generally show their weaknesses in long running consistency benchmark tests. However, in general day to day use, most people don't really use their SSDs that way. For people who do have such need, they generally have the budget to justify SSDs with DRAM.
@cyrax83: No, it's baked into the SSD firmware. If it is possible, reviewers would have tested larger HMB.
See my comment below (regarding NM790 vs P5 Plus). At 1TB, NM790 should be quite impressive.
I got this on last deal $79 & using for OS very quick this replaced my 500g Samsung & a noticeable speed upgrade very happy with it & shipping from BPC.
And the 2Tb's @ $149 and is included in this $5 off lexar promo and free delivery. Therefor the 2TB NM790 is $144 delivered.
Updated thx
Code not working on the 2TB version. Still a very good price without the discount so I ended up just ordering one for my PS5.
And the 4TB is on its way, arriving on the 4th of next month. It is $299 and is also included in the $5 off lexar promo and free shipping weekend. Therefor $294 delivered for 4TB.
Im guessing the Lexar is better than this Crucial as its using HMB?

Most, if not all DRAMless SSDs use HMB. P3 has / uses HMB as well. I don't know why when NM790 deals get posted, there are fanboys posting a HMB 3.0 comment. It's generally not a big deal. HMB is pretty standard nowadays.
Performance wise, NM790 is better that why the retailer is pricing it higher. P3 is QLC so P3's 4TB even at that discounted price is overpriced. However, we all want 4TB SSDs so we tend to raise our "acceptable price" and trick our own brains to think QLC vs TLC difference isn't significant at 4TB.
Thanks for the info much appreciated!
Could also be that many of us find SSDs a little complex. There are so many variables, not helped by companies switching out components during a products lifecycle (not just limited to SSDs as well on this last point). So many just look at headline details because that's as much as they want to try and understand without spending more time trying to break apart all the variables… at least, all of the above is me anyway :)
i personally prefer with dram. i was only copy pasting .. explaining what these offer and what the offer also works on
Where does it say included ? ?
Do you need to be logged in in order to apply the discount? I've tried both "LEXAR5" and "lexar5" in cart and it says both are invalid
I have the same issue
Code not working for me for $5 off. Tried on the 1TB.
Can confirm code not working.
same same
@Weshouldgetsushi: Managed to get $10 off using afterpay pulse rewards code. So grabbed the 2tb for $140.
@Robbo014: soz i meant do you have to buy through app or they give u a code? I got a $10 one atm but no code so assumed u had to buy through app passthrough
Thank you for posting. is Lexar NM790 better than Crucial P5 Plus?
P5 plus has Dram iirc so it's better? Coz ps5 doesn't support HMB so NM790 won't perform at its optimal.
Depends on what you are after and the size of the SSD. I don't own either SSD so I am basing on the reviews I saw and for NM790, since there is insufficient data, I used a mixture of Acer GM7 and ZhiTai TiPlus7100 review data to approximate NM790 performance.
It's great that BPC imported these for us, so we have a choice to purchase decent YMTC NAND based SSDs here. However, as these were imported earlier and BPC does have to factor in some buffer for warranty so the prices are no longer that great. If you don't get hyped up by CrystalDiskMark results and realise most of us don't have the ability to properly max out these SSDs, there are cheaper SSDs out there at the moment. Also, based on a previous comment from an OZBer, BPC's default warranty policy for SSDs may not be ideal for some people (that OZBer indicated it was store credit).
BPC does have to factor in some buffer
I see what you did there!
What if I don’t really care about max thoroughput, but only about “snappiness” while using windows, speed opening small files etc? Should we be looking for the fastest 4K random read/ write?
Also does having DRAM help in this case or does it not matter that much?
To clarify, performance wise, under general usage, NM790 1TB is at the same level as WD SN850 and Samsung 980 Pro, that includes random reads/writes. You also need to remember these DRAMless SSDs use HMB (so they take a small portion of your system RAM to use). One potential weakness of DRAMless SSDs could be writing small files but no SSDs are great at writing lots of small files.
If you are uneasy about DRAMless SSDs, then get a flagship SSDs with DRAM.
I don't own a NM790 (I am somewhat keen to get one, but I have too many SSDs already). Using Acer GM7's result:
https://cdn.mos.cms.futurecdn.net/uMZzDbyEYHT3e2b7g2nqim-970…
You can see the 1TB version does really well. One thing to bear in mind is that DRAMless SSDs borrow some DRAM from your system and as a result, they operate in a mode as if they have DRAM.
If you are getting a 2TB SSD, then getting a DRAM flagship PCIe gen 4 x4 latest SSD makes sense. For 1TB, as much as I want to tell you to get a DRAM PCIe gen 4 x4 SSD, NM790 1TB does surprisingly well. You can interpret that result chart in two ways: (1) at 1TB, NM790 does really well, beating 980 Pro or (2) you really want the best 1TB SSD and go for a latest gen flagship SSD.
Too many SSD deals not sure which to buy lol. Using in pci-e x3 slot, 2TB-4TB (probably 2TB), boot drive + some games. How much difference does dram make? Are we talking like 5% in real world speed or something - because then ill just opt to save the ~$50 and buy something like this?
Would this work in a PS5 if I bought an extra heatsink?
Yes.
The coupon code "LEXAR5" is not valid. for 2TB
QLC?
TLC, if this is QLC, people would have trashed it in the comments by now.
ha, cool! Thanks. I'll get the 4TB one when it's in. I know it doesn't have DRAM (I'll be writing to the drive a lot), but this HMB3 thing seems like a good alternative.
"No RGB!!!"
LEXAR5 NOT WOKRING
updated . Was that just on the 2TB?
It says the coupon is meant to last until later but it's already not working on 2tb either.
Never worked in the first place
lexar5 (in lowercase) just worked for me on the 2tb.
looks like it's working now. Now to decide on 2TB for $144 or 4TB for $294?
Ordered one, worked for 2TB :D
Note for US buyers that Lexar SSDs are blacklisted in the US because they're based on stolen technology and made in China by a state-owned company. I wouldn't buy this if you're not comfortable with that.
https://finance.yahoo.com/news/tech-war-us-blacklisted-ymtc-…
Amazon USA should stop selling all YMTC NAND based SSDs first. Amazon USA still have quite a few of them listed.
This is not the only OZB deal with YMTC NAND based SSDs and whether we like it or not, the latest gen of YMTC NANDs do perform fast. It's not a carbon copy of Samsung's NAND, it actually has other technologies. My interpretation on the issue is that Chinese government might have subsidised YMTC so it has an unfair advantage. Common consensus is YMTC's way to create their high end NAND isn't cheap.
This combination is the currently the only combo of a cost effective DRAMless PCIe gen 4 x4 SSD that reaches Sony PS5 recommended speed. It begs the questions why Samsung, WD, Seagate, Kingston etc… don't release competing products and want people to buy their flagship SSDs instead.
Warranty could be an issue.
Not too difficult to imagine why.
Remember the days when the market hasn't been flooded with the chips manufactured by Chinese companies? Whenever the supplies were tight, there were always some sort of "incidents" (fire, power outage, etc.) with the factories of Hynix, Samsung or Micron, which lifted the prices even further. Unfortunately for them, those days are gone now so that they no longer the only players in the arena.
The price per TB actually are in the $50s range for DRAMless 4x4 ones with TLC in China now ($260CNY for 1TB, and the fx rate is 4.79/aud as at now = $54AUD… pity they don't sell them directly to AU…). Most likely Samsung WD Seagate etc doesn't want to sacrifice their profit margin to compete in this section of the market, so that the only place left for them is to sell their flagship models.
p.s. And yes, in some cases, warranty could be an issue with some brands.
Hi p3rsonally：
In your link it doesn't show that Lexar has been blacklisted, can you give me the source where it says "Lexar SSDs are blacklisted in the US because they're based on stolen technology" so I can investigate.
Otherwise I believe it's a false statement because I know we are doing exceptionally well in USA. In fact we just sold 500+ pallets of our external SSDs to Costco in USA, it's available in every Costco store in USA.
BTW, I am a 15 years+ OZB user, this year it happend that I am in charge of Lexar ANZ operation, so I registered this new account just to be transparent.
Sweet got the 2TB for $134 with lexar5 and Afterpay $10 pulse reward. Replacing an old Intel 240GB SSD
Does this have Dram?
