Its a SCAM. 3224 kickstarter patreons waiting out hyperdisk moire than a year.with no project update since last may. The doesn't want refund money.

Also, if you look at the dimensions, the 2TB hyperdisk version is slightly larger than a typical external enclosure.  The site says:
"2TB HyperDisk is 90g and 134.73mm*37.9mm*10.76mm"
Icy Box IB-1817M-C31 says it is 105x40x15mm, which is much shorter.
I guess only the 512GB/1TB HyperDisk benefits from the smaller size and half the weight:
"45g and 66.73mm*37.90mm*10.76mm"

In the past, the Intel 660p 2TB NVMe SSD was selling for only $180.  With an additional $40 for the Icy Box, you could have a full 2TB external drive for only $220, which is cheaper than what HyperDisk wants, and you can build it yourself DIY immediately.  But recently the 660p 2TB has gone up to $250 probably because of the factories in China shutting down for quarantine.

I searched for some reviews with benchmarks and could only find this one:

At the 300 second mark, the guy uses CrystalDiskMark, but the top speed is stuck in the 400MB/s range.  It seems odd.  Maybe he's using a notebook that only has USB 3.0 and not USB3.1?
If you look at Anandtech's myDigitalSSD M2X NVMe external enclosure review, it shows USB 3.1 in the 900MB/s range, and USB 3.0 in the 400MB/s range.

Also they had a previous Kickstarter campaign for the same drive.  They haven't seem to deliver it yet.  The updates say that production is delayed because of quarantine measures.

There also seems to be very little special about this drive - it's just another USB 3.1G2 to NVMe bridge chip with an attached off-the-shelf m.2 SSD, just that they are using the slightly smaller 2242 standard rather than the more common 2280. I would definitely not back this, as I would want a company with actual warranty service and an established track record behind any storage device I use.

Quotealthough there is also a 2TB variant which apparently upgrades to DRAM instead.

Wow, that is a massive misreading - or does the author not know the function of DRAM in an SSD? Their Kickstarter does present it in an odd way, but I would expect a minimum of technical knowledge from a news writer covering this for a serious tech site like NBC. It is used for caching infrastructure data letting the SSD work faster through not having to read and write this to/from flash. Most SSDs have a DRAM buffer, but not low-end ones. All they are saying is that the 512GB and 1TB SKUs are based on DRAMless SSD designs, i.e. quite low end designs.

2TB of DRAM would cost tens of thousands of dollars and would need 12-16 tightly packed DIMMs like in a high end server. It definitely wouldn't fit in something like this. Also, DRAM is volatile, erasing all contents on power loss, so... not exactly ideal for portable storage, eh?

I just came here from reading the Anandtech comparison of USB 3.2 gen2 portable SSDs, and I got to say this definitely looks less compelling than their indiegogo page would make seem. They compare their device's speed to that of a microSD card, a hard drive, and an USB 2.0 thumb drive? Do they think their audience is stupid?

The price point looks very competitive... if only it were for a product available today. Having to wait three months (if they keep their schedule) and still with no independent tests makes it less palatable.

The "smallest" tag would be so much better if you could use it like a thumb drive, but no, you have to plug a cable into it which still makes it nearly as cumbersome as any other slightly larger SSD.

I also don't believe that this product will use Thunderbolt 3 despite the Notebookcheck article. The indiegogo page only mentions "3.1 Gen 2" at "10 Gbps" and also "M.2 NVMe" which I assume means that it's a 2232 or 2240 NVMe SSD plugged into their custom USB adapter board using an M.2 slot.
