The rollout of AMD’s PCIe 4.0 Ryzen platform has accelerated releases of PCIe 4.0 x4 SSD drives. Team Group this week introduced its versions of SSDs based on Phison’s PS5019-E16 controller. Interestingly, unlike competing drives using the same chip from other makers, Team Group’s T-Force Cardea Zero Z440 do not feature an aluminum heat spreader, but relies on a different cooling system.

Set to ship in 1 TB and 2 TB configurations, Team Group’s M.2-2280 T-Force Cardea Zero Z440 SSDs use 3D TLC NAND. As far as performance is concerned, the drives promise up to 5000 MB/s sequential read speeds, up to 4400 MB/s sequential write speeds, as well an 750K peak read/write random IOPS, which is in line with competitors.

Unlike most of drives featuring the Phison PS5019-E16 controller, Team Group’s T-Force Cardea Zero Z440 SSDs does not use a massive aluminum heat spreader, but comes with a graphene copper foil heat dissipation module that is only 1 mm thick. The use of a very thin cooler makes the drive compatible with upcoming laptops featuring a PCIe 4.0 x4 interface that will be available in the future. Meanwhile, according to Team Group, the graphene copper foil heat dissipation sticker reduces controller’s temperature from 61.8°C to 56.5°C when compared to the lack of any heat spreader.

As far as endurance and reliability levels are concerned, Team Group’s T-Force Cardea Zero Z440 SSDs are rated for up to 1800 or 3600 TB written over a five-year warranty period, depending on the drive's capacity.

    "...a graphene copper foil heat dissipation module that is only 1 mm thick."

    The marketing statement of the century. Someone give the clowns at Team Group a cookie for inventing a new flavor of snake oil. I'm sure the 30 something Lego-loving basement dwelling man children running RGB-festooned "battle stations" off mommy's power outlets will drink it up.

    What's wrong with liking Lego? x2

    IHS of the ssd. same shit, same shitty result except it might help to dissipate if we have ssd shield?
    Graphene was incredible at spreading heat around. Can I get a test of this ssd with and without the foil under same mobo & ssd shield?

    What's wrong with being moocher?

    You paint with a rather large wide brush.

    I really thought that would be a pretty specific, limited subset of people. I must report with some disappointment that I was wrong and the brush strokes were indeed wide.


    Except for shabby. Mooching is great for some people. I married a moocher at one point and put up with mooching for close to twenty years. Now some unsuspecting woman in another nation is supporting the ex-moocher that never grew up. I hope those Lego skills land a great paying job someday so I can finally get a child support check or two out of that deadbeat, but it's been a few years already and I suspect that minimum wage is optimistic at best.

    Was that who you were describing in your original post, your ex husband? I'm going to say yes since the correlation between graphene copper foil and Lego-loving basement dwelling man child is pretty slim.

    It's a sticker, not a heat spreader. So they put a little copper foil in their sticker, that doesn't make it a real

    Thank you. Yes, my inarticulate, bitter rampage about the computer industry and the suckers that get preyed upon by "clever" sales techniques that anyone with a couple of business college courses would see through was intended to point that out.

    It's just a sticker. It doesn't have significant mass or substantially increase the surface area which are both helpful in dissipating heat generated by electronic components. It could be made of rainbows and Harry Potter's dandruff OR graphene (apparently the newest marketing magic product differentiator) and copper and it would still do the same thing which is merely serve as a place on which to display the company's logo and name. Swinging a sticker as thermally beneficial is flirting with the line between sales speak and false advertising. The legal department's lawyer(s) must be sleeping in the wheelhouse if that claim is actually out of Team Group's product advertising.

    If I were advising them, I would have pointed them at any number of class action lawsuits that demonstrate the considerable risk the company is accepting at this point. Basement dwelling adult moochers aside, there are some fairly sophisticated consumers that purchase individual components. They could run convincing tests that will most likely debunk the thermal performance claims being made. It would have been much safer (although still shady as f*ck) to simply state the materials in the sticker and not proclaim a benefit. Buyers already falsely convinced that graphene = magic cooling would make the assumption on their own that the sticker is beneficial and Team Group would accept no increased risk of legal entanglement. Doing what they're doing now is just flipping stupid.
