Crucial’s T700 PCIe 5.0 SSD can throttle to HDD speeds without a cooler
ComputerBase’s recent tests of Crucial’s T700 and Corsair’s MP700 NVMe SSDs could further convince consumers that they should strongly consider paying extra for the heatsinks retailers offer with new drives. Their impressive read speeds, normally sitting in the neighborhood of 10GBps, completely evaporate if the SSDs get too hot.
EU Warns Apple About Limiting Speeds of Uncertified USB-C Cables for iPhones
It was rumored in February that Apple may be planning to limit charging speeds and other functionality of USB-C cables that are not certified under its “Made for iPhone” program. Like the Lightning port on existing iPhones, a small chip inside the USB-C port on iPhone 15 models would confirm the authenticity of the USB-C cable connected.
“I believe Apple will optimize the fast charging performance of MFi-certified chargers for the iPhone 15,” Apple analyst Ming-Chi Kuo said in March.
In response to this rumor, European Commissioner Thierry Breton has sent Apple a letter warning the company that limiting the functionality of USB-C cables would not be permitted and would prevent iPhones from being sold in the EU when the law goes into effect, according to German newspaper Die Zeit. The letter was obtained by German press agency DPA, and the report says the EU also warned Apple during a meeting in mid-March.
Given that it has until the end of 2024 to adhere to the law, Apple could still move forward with including an authentication chip in the USB-C port on iPhone 15 models later this year. And with iPhone 16 models expected to launch in September 2024, even those devices would be on the market before the law goes into effect.
The report says the EU intends to publish a guide to ensure a “uniform interpretation” of the legislation by the third quarter of this year.
It is worth emphasizing that Apple potentially limiting the functionality of uncertified USB-C cables connected to iPhone 15 models is only a rumor for now, so it remains to be seen whether or not the company actually moves forward with the alleged plans. iPads with USB-C ports do not have an authentication chip for this purpose.

New Version of Rust Speeds Compilation With Less Debugging Info By Default
Phoronix highlights two new improvements:
In order to speed-up compilation speeds, Rust 1.69 and moving forward debug information is no longer included in build scripts by default. Cargo will avoid emitting debug information in build scripts by default — leading to less informative backtraces in build scripts when problems arise, but faster build speeds by default. Those wanting the debug information emitted can now set the debug flag in their Cargo.toml configuration.
The Cargo build shipped by Rust 1.69 is also now capable of suggesting fixes automatically for some of the generated warnings. Cargo will also suggest using “cargo fix” / “cargo clippy –fix” when it knows the errors can be automatically fixed.

New 256GB Mac Mini and 512GB MacBook Pro Have Slower SSD Speeds Than Previous Models
A teardown of the new Mac mini shared by YouTube channel Brandon Geekabit reveals that the 256GB model is equipped with only a single 256GB storage chip, while the same configuration with the M1 chip has two 128GB chips. This difference explains why the new model has a slower SSD, as multiple NAND chips allow for faster speeds.
We have confirmed with the Blackmagic Disk Speed Test benchmarking app that SSD read and write speeds for the new 256GB Mac mini are each around 1,500 MB/s, which is anywhere from 30% to 50% slower than read and write speeds for the equivalent previous-generation model, although benchmark results and real-world performance can vary.
Customers who are looking for the fastest SSD speeds should ensure they configure their M2 Mac mini with at least 512GB of storage to avoid this issue. A slower SSD can impact file transfer speeds, and overall performance can also take a slight hit since Macs temporarily use SSD space as virtual memory when physical RAM is fully used.
As for the higher-end Mac mini with the M2 Pro chip, the base model with 512GB of storage appears to have two fewer NAND chips than the Intel-based model it replaced, according to a teardown shared by MacStadium’s Brian Stucki.
13-inch MacBook Pro and MacBook Air models with the M2 chip and 256GB of storage also have slower SSD speeds due to a single NAND chip, and evidently Apple has not decided to change course with the new Mac mini.
In a statement shared with The Verge last year, Apple claimed that M2-based Macs have “even faster” performance for real-world activities, but it’s unclear if the statement was referring to SSD performance or overall system performance:
Thanks to the performance increases of M2, the new MacBook Air and the 13-inch MacBook Pro are incredibly fast, even compared to Mac laptops with the powerful M1 chip. These new systems use a new higher density NAND that delivers 256GB storage using a single chip. While benchmarks of the 256GB SSD may show a difference compared to the previous generation, the performance of these M2 based systems for real world activities are even faster.
We have reached out to an Apple spokesperson for additional comment on the matter and will update this story if we hear back.
Update: As noted by 9to5Mac, the new MacBook Pro also has slower SSD speeds when configured with 512GB of storage due to a reduction in NAND chips.
