Exhibiting more than just ultra speeds, the PCIe SSD 250S delivers unbridled performance, low latency, and high stability for advanced video editors, gamers, and software engineers. Built with the PCI Express® Gen 4 x4 interface, 3D NAND flash, 8-channel controller, and a DRAM cache, the PCIe SSD 250S is ready to put excellence in your hands. Stunningly fast Transcend's PCIe SSD 250S complies with the latest NVMe 1.4 standard, supporting the PCIe™ Gen4 x4 interface, meaning four lanes transmit and receive data simultaneously. Its 8-channel controller delivers sequential R/W up to 7,500/6,700 MB/s, and IOPS up to 540K, delivering captivating performance and response time for desktops and laptops like never before. Level up with new-gen PCIe 4.0 The PCIe SSD 250S features the new PCIe 4.0 specification. It supports a bandwidth of 16 GT/s per lane as opposed to 8 GT/s per lane for PCIe 3.0. Downwards compatible with PCIe 3.0, PCIe 4.0 unleashes a higher processing speed for your computer and guarantees lower system latency. For content creators and gamers, this means a more seamless and immersive experience! As cool as always The PCIe SSD 250S has an integrated ultra-thin graphene heatsink to effectively improve the heat dissipation of the compact-sized SSD. The high conductivity of graphene quickly cools the system down, ensuring stable device performance. Small in size, large in capacity The PCIe SSD 250S comes in an M.2 2280 form factor. Despite its slim appearance, its capacity comes to 4TB, making it a great way for gamers, video editors, and software engineers to expand storage space! Better endurance, higher reliability Transcend's PCIe SSD 250S is engineered with LDPC (Low-Density Parity Check) coding, a powerful ECC algorithm, to keep data secure. Engineered with a dynamic thermal throttling mechanism, the temperature is precisely monitored and controlled for the PCIe SSD 250S, delivering superior endurance and stability for high-end applications. SSD Scope software Transcend SSD Scope is advanced, user-friendly software that makes it easy to ensure your Transcend SSD remains healthy, and continues to run fast and error-free by determining the condition and optimizing the performance of your drive. Guaranteed quality The PCIe SSD 250S is covered by a five-year limited warranty. To ensure the utmost level of quality, Transcend SSDs undergo rigorous testing at all stages of production, including tests for vibration, temperature and humidity, speed, and functionality.
