No, there's very little demand for MLC NAND in the enterprise/datacenter market. The endurance and performance of TLC SSDs is usually adequate when used in large quantities. For the rare cases where there's a need for significantly higher performance or endurance on a per-TB basis, Optane and Z-NAND drives usually make more sense than MLC.
Bought mine some months ago, then saw it fill up in days...
Put a couple of older SATA SSDs into a RAID0 just next to it to create the 2nd tier and would really like the control and flexibility back, I had with 4-8x hot-swap SATA...
I guess I'd want M.2 to U.2 trays for pennies and a switch/retimer for Dollars, but I fear they'll cost an SLC premium.
What annoys me, is that none of the flexibility they have as a manufacturer to create SLC/MLC/TLC/QLC out of the same controller and flash is passed on to the customer...
At these sizes, fixed functional allocation really is no longer cutting it, specially when most PCs don't have a whole array of M.2 slots nor the switch to manage them (things were so easy with SATA!).
I *know* which files/directories/partitions will be read-mostly and where there are hot-spots best kept in SLC or stuff that fits into MLC or TLC. Actually there is a lot of stuff or blocks that naturally migrate from SLC to QLC or even beyond, like transactional data in a RDBMs, but I want to decide when to do that.
So why not pass the control to the OS and thus ultimately the user? It *really* is just a setting on the controller most likely already managed at the erase block level...
Just discovered that I want is (cheap) NF1 trays and enclosures for my NVMe M.2 modules...
Problem is, that there seems to be nothing intermediate, like an 8x-12x chassis with 2-3x PCIe switch and retimers integrated that fits into the good old 5 1/4" HH slot where the CD-ROM used to be... (that currently has the 4/6/8x SATA hot-swap bays).
Current offerings from SuperMicro talk to high-end enterprise or HPC, but between NUCs and that stuff there is plenty of space for something intermediate, I think.

Is there a server version of this?Billy Tallis - Saturday, April 27, 2019 - link

I *literally* bought the 1TB version yesterday. You can thank me later for triggering this release!abufrejoval - Friday, April 26, 2019 - link

If you were one of my customers you would demand a refund and shlt on the counterNotmyusualid - Monday, April 29, 2019 - link
I was about to pull the trigger this evening!My new machine arrived today, and thought dam, only 1TB, but no other option.
Well, this is right on time (sung in the tone of Black Box) for me.

It's all here, Marvel 88NR2241 Intelligent NVMe Switch, found on this site (https://www.anandtech.com/show/12577/marvell-launc...so where can I buy it affordable...

"Nixiang lists the SSD for ¥8888 ($1,320), which means that the price of the drive in the US would be around $1,200."Need to get your numbers straight. ¥ 8888 (JPY) is approximately $80 USD at current exchange rates.

Nixiang is a Chinese retailer, ¥ is used for both JPY _and_ CNY/RMB. But feel free to correct them, I'd love to hear how that conversation goes. :-)halikarnas - Saturday, April 27, 2019 - link
Since when Chinese retailers started to use Japanese yen for transactions ? ¥ 8888 (CNY) is approximately $ 1,320 at current exchange rates.Valantar - Saturday, April 27, 2019 - link
So when's the 3TB TLC EVO version of this coming?Morawka - Sunday, April 28, 2019 - link
$1200 for 2TB?! that's about 4X the price of a 970 Pro 1TB ($350 USD) drive for 2X the capacity. The price will have to come down before I bite.Notmyusualid - Monday, April 29, 2019 - link
Here in Thailand, at one of the big retailers 'Banana IT', I priced the 1TB Pro at 20,900 THB ($654 USD) just yesterday.It mattered not to them what it cost at other places or countries.
