ChaitanyaAny wording on the price?
My bad, I missed that wasn't included in the press release, I've added pricing at the end now.
Got a review coming of the F4-425 Plus, but it wasn't possible to get it done for the announcement.
Overall it's a pretty solid upgrade over their older models.

Pricing especially for that 4 bay model is quite decent given the feature set. If it performs well then it should be a good goto NAS for good chunk of users.

Let's put it this way, my only real gripe is the lack of 10 Gbps Ethernet.
TerraMaster has worked out most of the kinks I've pointed out in previous reviews.

The three M.2 will be only Gen3x1 or 2xGen3x2 + Gen3x1 at most. 2x5GbE eats up two lanes, same as 2-4xSATA (probably two native ports on F2, costing one lane each, and ASM1164/JMB585 with 4-5xSATA @Gen3x2 on F4), leaving just 5 lanes.
While some Alder Lake-N/Twinlake NAS-boards connect ASM1166 to just one lane, I don't think Terramaster would do that. Either way, Gen3x1 nearly saturates 10GbE or 2x5GbE with Link Aggregation.

I would prefer a Gen3x4-slot to plig in an AIC with 10GbE+2xM.2 like QNAP offers, though.

They're all PCIe 3.0 x1. This is very common on all NAS devices based on lower-end SoCs, but it's not an issue, since the Ethernet interface is the bottleneck, not the SSD.
PCIe 3.0 x1 isn't fast enough for 10 Gbps.

TerraMaster doesn't have any current "desktop" models with expansion slots that I'm aware of.

No, even on this device the Ethernet is not necessarily the bottleneck. If you use a Switch with 2.5/5GbE- (very rare) or 2.5/5/10GbE-ports and link aggregation, you can get the same speed with 2x5GbE as with 1x10GbE and that is ~1.1GB/s, while Gen3x1 is only 985MB/s in theory, but below 900MB/s in reality.
I don't know how these SSD are handled normally on NAS, if they are used as SSD-Cache. Are they put into RAID0 or RAID1 or JBOD?

No, but QNAP and even Synlogy do have some comparable, if older NAS. QNAP TS-x62 and TS-x64 have one Gen3x2-slot, which is perfect for 10GbE, DS723+/923+/1523+ have a upgrade-port for 10GbE, which is essentially the same, but proprietary. DS725+/925+ scraps this port, of course, because why should they be any good, only 1525+ keeps it.

QNAP TS-x62A will be x62 with x64's SoC, but will apparently scrape the Gen3x2-slot, sadly (of course, without upgrading the M.2 ports, just wasting lanes), as does the (china only?) Qu50x-series with N355.

QNAP TS-x73A uses the same SoC as DS925+/1523+/1525+, but offers a Gen3x4-slot, which is enough for 2x10GbE (and even 1x25GbE). I don't know how the 2xM.2 are wired, but the V1500 SoC has 16 lanes Gen3 and 2x10GbE MAC, while the R1600 has 8 lanes only. So all those DS72x/92x/152x and even TS-x73A don't even use half of the SoC. They could offer a Gen3x8-Slot on the V1500 plus 2x10GbE and still have enough lanes for 2x5GbE and 2xM.2 Gen3x2 plus up to 6xSATA.
But they should switch to Ryzen embedded V3C14 already with 20 lanes Gen4 plus 2x10GbE.

I just hope QNAP will release a real TS-x64-successor with Twin Lake and keep the Gen3x2-slot.

Well, Asustor has an upgraded version of the AS5404T with dual 5 Gbps ports coming and as they have working SMB multichannel, you should indeed get close to 10 Gbps speeds, in some scenarios, but as shown in the review, it doesn't always give you a performance benefit. Even so, with overheads etc. you're not likely to get more than those 900 MB/s out of the new models either.

Indeed and I guess that's some kind of business decision, as even Asustor has some models with expansion slots. Having had a look at TerraMaster's enterprise models, it seems like there are no expansion slots on those either, which is a bit odd.

QNAP does seem to be the best option hardware wise if you're looking for a NAS you can add various features to, but they seem to be somewhat behind software wise, but it could be that the TS-432X I reviewed is just an oddball and hopefully they use a more recent Linux kernel in their x64 based models.
