Silkland Releases 4ft USB4 Cable: 40Gbps Data Sync, 240W Rapid Charging

[TheLostSwede]

Silkland, a tech brand specializing in cables and accessories, has once again raised the bar with its new 4ft USB-IF Certified USB4 Cable. This latest cable delivers unmatched speed and convenience, and works seamlessly with all Thunderbolt 4 / 3 / Type C devices, making it an essential tool for professionals and everyday users alike.

Silkland's latest offering stands out as the longest USB-IF certified USB4 cable, measuring at 4ft. This means users can now enjoy a longer reach without compromising speed and efficiency compared to the standard 3.3ft cables. Fully supports the latest features to future-proof your setup. Backward compatible with USB 3.2 Gen 2, USB 3.2 Gen 2 x2.




One of the unique features of this USB4 cable is its small interface. Unlike the bulky designs of others, it ensures compatibility with cased devices. Moreover, its Netbraid-48 construction enhances both softness and durability, promising longevity and sustained quality through extensive use.

Beyond convenience and durability, the Silkland 4ft USB4 Cable is 2x faster than the previous generation USB4 cable, delivering up to 40 Gbps bandwidth. With this speed, users can copy 14 hours of high-definition video or 25,000 photos in just one minute, saving valuable time and effort.

In addition to its data sync capabilities, the Silkland 4ft USB4 Cable offers rapid charging up to 240 W (48 V/5 A) power supply. It is also backward compatible with 100 W, 140 W, and 180 W in Extended Power Range (EPR), making it a versatile and reliable charging solution. Equipped with an E-Marker chip, it ensures safety, stability, and battery protection for worry-free use.

For professionals, the cable offers a single 8K@60 Hz / 5K@60 Hz / 4K@144 Hz or dual 4K@60 Hz display support. This feature allows users to connect their laptop or dock to a monitor and get a crisp detail and full-color gamut view. The cable also supports MST Daisy Chain, improving work efficiency and project professionalism.

Weird how I've totally missed the whole USB4, or is it just a rebranded version of that craziness of rebranding all the USB3 stuff?

I mean USB3 was hyped to the moon back in the days.

No re-branding, it's technically Thunderbolt 3, but better.
I'd suggest you read this.

USB4 is Coming - Everything You Need to Know

USB4 is the next evolution of the USB standard, but it's quite different from its predecessors as it brings with it support for DisplayPort connectivity, as well as optional PCI-Express and Thunderbolt 3 support. It tries to fix some technical issues, but adds a few of its own, but at least the...

USB3 deserved some of its hype considering how horrible USB2 was for external drives. But then it turned into a complete clusterfuck of different speed ratings and charger support.

USB4 is unfortunately little better. You have USB4 Gen 2 (10 or 20 Gbit/s depending on single or dual lane), USB4 Gen 3 (20 or 40 Gbit/s), USB4 Gen 4 (80 in dual lane, or 120 Gbit/s in assymetric lane). A cable/port marked 10Gbps can be using anything from USB 3.2 Gen 1x2 to USB4 Gen 2x1. Also it may or may not tunnel displayport or pci express, and apparently power delivery is required (good question if the cable supports it or not).

So it's the same insanity as USB3+ connectors. It's only use right now is being a dedicated phone cable.

USB3 deserved some of its hype considering how horrible USB2 was for external drives. But then it turned into a complete clusterfuck of different speed ratings and charger support.

USB PD is an independent part of the spec and has nothing to do with the data part of the USB standard.

USB4 is unfortunately little better. You have USB4 Gen 2 (10 or 20 Gbit/s depending on single or dual lane),

So far, there are zero devices that support anything slower than 40 Gbps and the 10 Gbps speed is some kind of fall back and will never be a speed grade for USB4. The slowest data rate is 20 Gbps.

USB4 Gen 3 (20 or 40 Gbit/s),

Sorry, but this is just plain USB4, regardless of what the mode might be called and it's 40 Gbps. As above, there's nothing slower than 40 Gbps today.

USB4 Gen 4 (80 in dual lane, or 120 Gbit/s in assymetric lane).

This was developed to compete with Thunderbolt 5 and yes, it's a bit odd, but the asymmetric mode is only for displays and not meant for data, at least not right now. This is still using the same cables.

A cable/port marked 10Gbps can be using anything from USB 3.2 Gen 1x2 to USB4 Gen 2x1.

No it can not, as there are no 10 or 20 Gbps USB4 ports. A 10 Gbps cable might work with USB4 though, but at reduced speed, in fall back mode.

Also it may or may not tunnel displayport or pci express,

Only end devices are limited, host controllers and hubs have to support PCIe tunnelling, but host controllers don't have to support DP tunnelling.

and apparently power delivery is required (good question if the cable supports it or not).

No it's not. USB4 is only required to deliver 7.5 W and Thunderbolt 15 W. Yes, USB4 is USB PD compliant and most cables support at least 100 W, although as you can see, more recent cables do 240 W, but it's not a requirement, even if it's a good thing that most cables so far do support USB PD 3.0 or 3.1.

So it's the same insanity as USB3+ connectors. It's only use right now is being a dedicated phone cable.

Not really, since all host controllers today are 40 Gbps and delivers PCIe and DP tunnelling, so there are currently exactly zero issues.
You've been drinking the Intel cool aid which says Thunderbolt is superior, which is funny, when USB4 technically is an improved version of Thunderbolt 3/4 which supports 40 Gbps of data, instead of 32 Gbps.
Also note that USB4 cables are compatible with Thunderbolt and vice versa.
Please don't spread FUD about something you clearly haven't read up on or understood properly.
I'd suggest you read my USB4 primer article as well.

$100 or cheaper?

The cable is $25

It's a 1.2 meter cable, i.e. they've managed to certify a 20 cm longer cable than anyone else so far.

Oh. And it showed a 20% coupon for me.

Ordered one. Thanks for the link.

So, you're saying that if I took a m.2 nvme enclosure with USB4 it'd be faster than the sam exact drive in a Thunderbolt 4 enclosure? I was always wondering about that, I knew that the 40Gbps with Thunderbolt was BS (like how wifi routers advertise their speed by combining all frequency bandwidths instead of just telling you whats the fastest a single connecrion can achieve....which, BTW, is kind of difficult information to find when shopping for a router) and that it added in the 8Gbps for DP protocol and such and I assumed USB4 was doing the same BS, but the 40G is on USB4 could be used entirely for data?

USB4 is literally the data part of Thunderbolt 4.

Almost. The data sequencing protocol is a bit different.

To people outside America they are different things

So it's the same insanity as USB3+ connectors. It's only use right now is being a dedicated phone cable.

And don't forget that USB3 or 4 does not carry a lot of power unless it is marked with PD/power delivery. And then it is usually either 60W or 100W.
That for example is a problem for my Quest 3. I had to buy a jank cable with a seperate power connector, since most mainboards, even wth USB4, don't carry above 7,5W power over USB.

It's a 1.2 meter cable, i.e. they've managed to certify a 20 cm longer cable than anyone else so far.

On the german Amazon page they sell upto 3m or 10ft, BUT it is NOT certified. Only upto 4ft.

The 4ft is 21,99€ down from 24,99€ and has a 30% discount on top....bought one for 15,39€.

Yes and no. There appears to be some limitations in the current hardware implementations so you won't see much over 4 GB/s, rather than a theoretical max of 5 GB/s. Then again, Thunderbolt 3/4 should deliver 4 GB/s in theory, but only delivers just over 3 GB/s.

Only if you speak English, as we spell it meter in Sweden and it's the same in Norwegian and Danish, which is also why I write meter sometimes in English, even though I should know better.

Same in the US, but anything not certified is unlikely to work at 40 Gbps.

As long as we stay away from binary gi-bi-bits per imperial second, and BTU per hour for USB power delivery, satellites won't start falling from the sky.
