- Huawei claims backup compression ratios reaching an extraordinary 90:1 level
- Patented algorithms sit at the centre of Huawei's reduction strategy
- Four separate reduction stages shrink data before long-term storage
Huawei has unveiled a hardware compression card claiming a data reduction ratio reaching as high as 90:1 under suitable workloads.
The figure applies specifically to backup data carrying high redundancy, such as daily full virtual machine backups accumulated over time.
Huawei says this result sits 20% higher than the leading alternative currently available across the enterprise storage market.
A patented algorithm built around a nonlinear transformationThe card forms part of Huawei's all-flash OceanProtect Backup Storage systems, including two newly announced models, the X8100 and X9100.
Compression relies on a proprietary algorithm family Huawei calls HZU, described by the company as using a fast nonlinear transformation paired with lightweight context prediction methods.
Huawei says this approach outperforms the long-established Lempel-Ziv compression paradigm, boosting the achievable compression ratio by roughly 30% under comparable conditions.
The dynamic technique is patented, covering both the deduplication and compression methods used throughout Huawei's wider backup architecture.
Selecting the most suitable algorithm depends heavily on the specific backup policy and underlying data types involved in each deployment.
Earlier generation OceanProtect systems achieved a comparatively modest 72:1 reduction ratio, meaning the newly announced generation also runs up to 50% faster.
Reduction pipeline relies on dense SSD deploymentReduction happens across four distinct stages, beginning with preprocessing designed to clean incoming data before further processing occurs.
This is followed by multi-layer, inline, and variable-length deduplication, then HZBC compression, and finally byte-level compaction applied to whatever data remains.
The compression card additionally offloads up to 22% of processing demand away from the backup system's main CPU during operation.
That offload matters because OceanProtect systems rely on all-flash media rather than cheaper disk-based alternatives for storage.
Huawei specifically uses QLC storage media paired with an adaptive SLC zone reserved for frequently accessed hot data.
This combination is intended to support faster data recovery once backups eventually need restoring during outages.
Since SSD capacity costs considerably more than disk per terabyte, squeezing more effective storage out of the same physical drives directly improves the economics of an all-flash backup system.
In that sense, the compression algorithm and the SSD architecture work together, with the algorithm doing the actual reduction and the flash media determining why that reduction pays off.
Prospective customers will likely need to test the OceanProtect platform directly against their own backup data sets.
Whether customers experience reductions approaching 90:1 will likely depend heavily on datasets, retention policies, and real-world deployment conditions.

If you want to up your coffee game at home, the Breville Bambino Plus is a fantastic addition, being compact enough to fit into any kitchen, while also being more than capable of brewing a delicious shot of espresso.
And right now it’s received a huge discount of AU$230 at Amazon, bringing it down to AU$499. That’s a great price, and normally I’d be singing its praises from the rooftops, but you can save even more by getting yourself an exclusive code from our dedicated Breville coupon page, then head directly to the maker and apply that unique one-time code at checkout.
Follow those steps and you can get the Bambino Plus for the even lower price of AU$449.10. Do note that the biggest saving only applies to the Stainless Steel, Black Truffle and Sea Salt colours. You can still get other colour options from Breville for AU$494.10 using the same discount code.
The Breville Bambino Plus is incredibly simple to use, and can take care of most of the coffee making process for you. Grind some beans into the porta filter, insert it into the group head and use the one-touch controls to brew. It also has a hands-free milk texturing system for expertly frothed milk, while ThermoJet technology means the machine is ready to use in seconds. There's very little you need to do to simply enjoy the results. View Deal
If you’ve ever thought going hands-on with an espresso machine would be too difficult to master, then the Bambino Plus is here to bust that myth. While it may look like a manual machine, it’s realistically a semi-automatic model.
You will need to adjust the grind size depending on whether you want a single or double shot, and then tamp the coffee grounds yourself, but Breville has preset the machine to grind the optimum amount each time.
To make things even easier, it benefits from the company’s Auto MilQ system to automatically foam milk, whether it be dairy or plant-based. To be honest, I was a little surprised to learn it had this feature, as I thought it would have been reserved for Breville’s more expensive models.
Our Breville Bambino Plus review gave it a strong 4.5 stars out of five when we originally put it through its paces. We called it a “fantastic machine that’s packed with smart features to help you make the smoothest and professional-looking coffee around”. We appreciated the fast heat-up time and the level of customisation on offer.
As with any coffee machine, you’ll need to keep on top of maintenance to keep it working at its best, and it won’t suit pod users, but that’s all there is to criticise. For many people, it’ll be one of the best espresso machines you can buy if you want a capable and more affordable choice compared to some premium options.
Update: Now Prime Day's over, the mini PC has risen in price. The cheapest I can find the K13 is $590 (was $900) at GMKtec.
That's twenty bucks more than its previous low price for most of the Prime Day sale. But still a significant saving. I've updated the deal block below with the new price and a link to the now expired Amazon deal. Alternatively, at Amazon, it's now priced at $680. That's the same as on Newegg, too.
In the UK, the K13 mini PC is still £539 with voucher (was £729) at Amazon.

Looking for the best value mini PC deal for Prime Day - then this is it. The GMKtec K13 just dropped to $540 (was $950) at Amazon.
I've checked, and that's its lowest ever price. I was price-checking my live Prime Day home office deals hub when I spotted the change - previously it was priced at $570 before it got the new $540 tag.
The system itself comes equipped with Intel Ultra 7 256V processor, 16GB LPDDR5, and 512GB SSD that's expandable up to a massive 16TB thanks to dual Gen4 NVMe slots. When we benchmarked the AI mini PC in our review, we found it "a thoughtfully engineered slice of modern computing" that showcases the best of what Intel does.

During tests, the K13 from the ever reliable GMKtec proved to be a powerful little system, especially for local AI. It's a uniquely portable and compact design, too, coming in a rectangle rather than the usual square box.

In my guide to the best mini PCs, I included the K13 in the 'Also Tested category, where I highlighted its particular excellence as a mini PC for local AI and data speeds. The system is capable of 115 TOPS total AI.
There's also an ultra-fast 5 GbE LAN port and dual USB4 ports capable of daisy-chaining accessories like eGPUs, storage arrays, and capture cards.
With the RAM soldered to the board, expandability it limited to the storage - which supports dual 8TB lanes. Still, for anyone who needs 16TB total SSD capacity, this is golden.
In the final verdict of our review, we said: "if your use case is modern, efficiency-focused desktop computing, perhaps content creation, AI experimentation, clean-desk professional work, or a powerful behind-monitor media machine, then K13 makes a compelling argument. There is plenty to like here, and relatively few reasons to avoid this machine, not least the price."
Doubly so now the K13 hits a new low $540. I don't expect this one to stay at that price for long.
