New Solid State Drives Approaching Top Speed
New Kingston Raw Pawns are getting close to the limit of what they can do with PCIe 4.0.
This week, Kingston pulled the plug on two of its fastest solid-state drives ever: the KC3000 and the Fury Renegade. Both tags reported transfer speeds of 7000MB/s — or more.
These speeds require their own bandwidth, and therefore we are talking here of course about NVMe PCIe 4.0-based SSDs. Even with this fast data bus, these speeds weren’t normal, but now both better controllers and better memory have found their way to the market.
Confused? See our glossary at the bottom of the issue.
The fastest SSDs we’ve tested so far were around 7000MB/s for reading and 5000MB/s for writing. With the new generation of SSDs, it’s basically the writing speed that gets a boost.
The fact that the reading speed does not increase in turn is due to the fact that one has reached, so to speak, the maximum that is possible with four PCIe 4.0 lanes, where the theoretical maximum transfer speed is 7877 MB / s.
In fact, the development was rather fast. Especially considering that the fastest SSDs are arguably a niche product to date, even though AMD got this in place for PCIe 4.0 with the Ryzen 3000 series two years ago.
But in hindsight, Intel also came up with processors that support this, and the PlayStation 5 also uses it, so there are more and more PCs that can use ultra-fast memory sticks like the Kingston ones here.
The two new models from Kingston have nearly identical specifications. Both come in capacities from 500MB to 4GB and are normally only available in M. 2 format – so they will usually be installed directly on the motherboard.
From what we can understand, there are no physical differences between the two SSDs, as long as we ignore the heatsink design. The fact that the two models have different characteristics is due to the fact that the controller is programmed to give them that.
|7000 MB/sec||7300 MB/sec|
|7000 MB/sec||7000 MB/sec|
|Million (read/write)||Million (read/write)|
|Which ends in E18||Which ends in E18|

|1600 TB||2000 TB|
|3200 TB||4000 TB|
|1.8 million hours||1.8 million hours|

To us, it appears to be primarily a marketing ploy. First, the focus of sales is on usage, and the other is on the users themselves.
In the above table, we have listed some of the most important features. We should also mention that write speed does not apply to all capacities, first with the 2TB models we get full credit.
We note that the Fury Renegade is run to be a bit faster and is said to hold more with a higher TBW number. TBW stands for Total written bytes And it says something about how much the disk has to hold when writing to it.
For the two new Kingston models, this number is relatively high and in this sense appears to be fast and powerful than the SSDs we are dealing with.
Variants of one terabyte or more have such fast write speeds that they could be able to do the job as additional PlayStation 5 storage.
When it comes to choosing between the KC3000 and the Fury Renegade, we imagine it wouldn’t be much of a difference in practical use, but we’re still told that the Fury Renegade will be a bit more expensive. This may have been a factor explaining why they performed poorly.
Strictly speaking, we should not pretend that this is a stupid strategy. Western Digital does just that with its WD Black SN850, which also topped our SSD assembly test our spring.
Kingston isn’t the only manufacturer releasing new SSD drives these days. Teamgroup has at least revealed the T-Force Cardea A440 Pro, which will have speeds of 7400MB/s read and 7000MB/s write.
