Used enterprise SSDs offer significantly higher TBW ratings (3000-5000+ TBW vs 300-600 TBW for consumer drives), more consistent performance under sustained workloads, and better cost-per-gigabyte compared to new consumer SSDs. Even after 20-30% of their rated write cycles, used enterprise drives often outlast brand-new consumer alternatives for typical home use. The author recommends considering this option for PC builders seeking reliability and value.

Sử dụng SSD M.2 NVMe qua adapter PCIe cho hiệu năng tương đương khi cắm trực tiếp vào khe M.2 trên bo mạch chủ, chênh lệch nằm trong sai số đo lường. Adapter PCIe hữu ích khi khe M.2 trên bo mạch đầy, bo mạch Intel giảm băng thông PCIe GPU do SSD Gen 5, hoặc khi dùng card phân chia (bifurcation) để triển khai RAID 0 tăng tốc độ. Giao thức NVMe hoạt động trên PCIe nên adapter không gây ảnh hưởng đáng kể đến hiệu suất trong sử dụng hàng ngày.
Lập trình viên nên đọc bài này để hiểu cách tối ưu hóa hệ thống lưu trữ cho ứng dụng phát triển phần mềm, đặc biệt là khi cần giải quyết vấn đề về không gian lưu trữ hoặc kết nối PCIe hiệu quả hơn khi sử dụng các adapter M.2 NVMe.
Firefly has launched the AIBOX-9075, an industrial Edge AI box powered by the Qualcomm DragonWing IQ-9075 SoC. It delivers up to 200 TOPS of AI performance via a Hexagon Tensor Processor NPU, paired with 36GB LPDDR5 ECC memory and 128GB UFS 2.2 storage. The device targets edge AI workloads including private LLM deployment, robotics, and computer vision. It supports popular AI frameworks (TensorFlow, PyTorch, ONNX) and LLMs such as DeepSeek-R1, Llama, and Gemma, achieving up to 22 tokens/s with Llama2-7B. Connectivity includes dual 2.5GbE with TSN, optional Wi-Fi 6, 4G/5G, and 8x GMSL2 camera inputs. The rugged aluminum enclosure operates from -40°C to 85°C. It runs Ubuntu and Yocto Linux and is priced at $1,239 from the Firefly store.
The Linux 7.2 merge window includes a fix for a PCIe bug where devices could be inadvertently restricted to 2.5 GT/s link speed after hot-plug events. The issue stems from a 2.5 GT/s speed clamp introduced in 2023 to work around PCIe link training failures, which could incorrectly persist for subsequently plugged-in devices due to an event race condition. The fix discards Vendor:Device ID matching in the failed-link retraining quirk and reverts to the original target link speed if final retraining fails. The patch is also slated for backporting to stable kernel versions. Additionally, Intel QAT, DSA, and IAA accelerators were added to the P2PDMA whitelist, and a new UltraRISC DP1000 PCIe controller driver was introduced.
The ASUS Vivobook S16 is on sale during Amazon Prime Day 2026 at its lowest price ever — $880 (down from $1,095). It features an AMD Ryzen AI 7 350 CPU, a 16-inch 3K OLED display at 120Hz, 16GB RAM, 1TB storage, and a 75Wh battery rated for up to 14 hours. The laptop is thin and light at 0.55 inches and 3.31 lbs, with integrated graphics rather than a discrete GPU. It includes a solid port selection: HDMI, two USB-C, microSD, audio jack, and two USB-A ports.
A hands-on review of the Gamrombo PS5 controller, a ~£40 third-party alternative to the official DualSense. It works out of the box on Linux via USB-C and Bluetooth, registers as a Sony DualSense, and supports touchpad gestures, vibration, speaker, and 3.5mm audio. Extras include programmable macro buttons and a turbo function. Downsides include no microphone, Windows-only firmware updater distributed via WeTransfer, no charging dock support, and a slightly cheaper feel compared to the official controller.
IBM has announced a sub-1nm (0.7nm / 7-angstrom) chip design that packs nearly 100 billion transistors onto a fingernail-sized surface — roughly double the density of its 2021 2nm chip — with up to 50% more performance or 70% better energy efficiency. The key innovation is a 3D 'nanostack' architecture that stacks transistors vertically rather than shrinking them further. A South African quantum computing expert, Francesco Petruccione of NITheCS and Stellenbosch University, calls it a genuine engineering milestone and highlights implications for AI workloads, data centre energy costs, and on-device AI. IBM also reports a ~40% improvement in on-chip SRAM, easing the memory bottleneck for AI inference. Commercial production is estimated within five years, though significant manufacturing challenges remain.
CHUWI has opened pre-orders for the UniBook, a 14-inch laptop priced at $449 (regular $499) powered by Intel's new Core 3 304 'Wildcat Lake' processor. The penta-core SoC is built on Intel 18A and features an Xe3 GPU and 15 TOPS NPU. The laptop ships with 8GB LPDDR5 RAM, a 256GB NVMe SSD, a 1920×1200 IPS display, Wi-Fi 6, and a 53.38Wh battery rated for up to 13 hours. Early PassMark benchmarks suggest performance comparable to Apple's A18 Pro. Shipping is expected to start July 20, 2026, making this one of the first consumer Wildcat Lake laptops available for purchase.
