lexar NM790 4TB is $329 in Pc case gear. pay $30 extra you can get fast speed and longer durability (3000 TBW), NM790 use NVMe 2.0 Technology
I think the ATL for that Lexar was about $240 in 2023. But $329 is a decent price. Hopefully see some downward movement on the SSD prices, although the declining Australian $ will cancel out some of it.
If using for external SSD purposes, then needs a good, external case with heatsink.
any recommended case?
I'm disappointed with Lexar's NM790 SSD because of its inadequate Linux support. Although some progress has been made, the drive still lacks full compatibility across all Linux distributions. I'd be willing to pay a bit more for better support.
I purchased $235 offer for Windows, but at a higher cost, I'd rather avoid the hassle of having to upgrade any Linux kernels below version 6.5.5 especially because i download and try more linux iso's 🐧 than linux iso's 🏴☠️
Not sure how that's Lexar's fault?
It is a Maxon MAP1602A controller issue and looks like Maxon has no interest fixing it. So for now, make sure you use a linux distribution with a new enough kernel.
Lacks compatibilty? Or lacks full performance?
SSD doesn't get detected during boot so cannot be used as a boot SSD on an linux machine running an older kernel (i.e. you need to use a slightly older linux kernel for work). You could compile your own linux kernel to add the workaround delay detect code change in if you want.
Linux kernel 6.5.5 or later has the workaround included so probably not an issue for most people.
@netsurfer: Not sure what you're talking about but I am booting into the latest Ubuntu OS fine with the Lexar NM790. I am using it as my second OS just incase Windows goes boom after an auto updates.
but I am booting into the latest Ubuntu OS fine
I didn't neg you (I don't neg comments, so I don't neg deals either). I did mention older kernel(s), furthermore, mantra did point out which kernel version (6.5.5) is the first one to add the fix / workaround. It was an issue in 2023 (when NM790 4TB was $255 or less so lots of people bought NM790 4TB SSDs).
Yes, for home use, we tend to run the latest build. However, for work, there are times you need to run older linux distributions. Work related setup may stick with stable / LTS kernels (6.5.x isn't LTS so if you needed the fix asap back in 2023, you had to run an non-LTS linux, or build your own kernel with the fix).
Not worth these prices without dram
I’m also sceptical. Apple tells me I’ll need $1500 to upgrade to this much storage. Surely Tim Apple wouldn’t steer me wrong.
His name is Tim Cook, the CEO of Apple
President Trump calls Apple CEO ‘Tim Apple’ instead of Tim Cook
Tim Cook is now Tim Apple on TwitterSince that comment is clearly sarcastic, Tim Apple makes it funnier / better.
Not Tim Cook, should be Team Crook. Charging 1500 for a SSD is daylight robbery.
He even changed his own display name on socials after Trump screwed up his name.
Was a good laugh.

This is a max $250 drive
Team have shrinkflated the specs hard cutting a third of the endurance, just under 10% of sequential read/write and the biggest red flag, dropped read/write IOPS entirely
The Maxio controller is not a heat monster meaning Team is rolling the dice with lower bin/reject quality YMTC flash

Possible, but not neccisarily.
A lot of cost comes from a products support window. Less warranty claims and less support staff for a shorter warranty.
You're right that the lexar drive is better value at this price, but anything else is guessing.
Since very few drives are used to that extent before replacement, we also don't know that lexar isnt inflating YMTC's numbers either; to look better in the market and 'hope for the best'.
Not sure how reliable this review is:
TEAMGROUP Z44A7 2TB M.2 NVMe SSD Review - Benchmarks
Linux based tests and 2TB version. My guess is Z44A7 benefited from a newer revision of Maxon firmware perhaps. Lexar NM790 does seem to over-quoting specs a bit. NM790 2TB results seem surprisingly low for some reason in linux. My NM790 is inside a PS5 so can't test it.
My subjective take on the lower specs, no IOPs specs and lower TBW is that approach opens the door for component swap later on. Less spare cells and/or slightly inferior grade NANDs are possible. I have cheap Kingston SSDs with factory pre-disabled bad cells (inferior grade Micron NANDs).
Do you know of some resource(s) to help people who don't really keep up with the SSD scene much (me, and presumably most commenters) to quickly parse how good a drive is (and so consequently evaluate SSD deals)? It feels like if the drive isn't in the ~10 most popular models (or easily comparable to them) it's really hard to figure out if it's a good deal or just "okay" without spending an hour researching the drive and several peers.
wow
