Specs and Performance Comparison
Interface generation
The GIGABYTE AORUS Gen5 12000 1TB SSD uses a PCI Express Gen5 x4 interface with NVMe 2.0 support. This newer standard allows for wider data lanes and higher bandwidth potential compared to previous generations. The GIGABYTE AORUS Gen4 7000E SSD relies on a PCI Express Gen4 x4 interface with NVMe 1.4. While Gen4 is still very fast for most users, it represents an older generation of connectivity. If your motherboard supports PCIe 5.0, the Gen5 drive can utilize that extra bandwidth. Otherwise, it will fall back to Gen4 speeds. The Gen5 interface is technically superior for future-proofing.
Sequential read speed
Speed is where the difference becomes most apparent. The GIGABYTE AORUS Gen5 12000 1TB SSD offers sequential read speeds of up to 11700 MB/s. This is among the fastest speeds available for consumer NVMe drives today. In contrast, the GIGABYTE AORUS Gen4 7000E SSD does not list a specific sequential read speed in the provided data. However, as a Gen4 drive, its theoretical maximum is significantly lower than the Gen5 model. For tasks like loading large game assets or transferring massive video files, the Gen5 drive will complete these operations much faster due to its higher bandwidth capabilities.
Sequential write speed
Write performance matters for saving large files quickly. The GIGABYTE AORUS Gen5 12000 1TB SSD provides sequential write speeds of up to 9500 MB/s. This high throughput helps maintain performance during sustained large file transfers. The GIGABYTE AORUS Gen4 7000E SSD does not specify its write speed in the given specifications. Generally, Gen4 drives cap out well below 9500 MB/s. The Gen5 drive’s ability to write data at nearly 10 GB/s gives it a clear advantage for content creators who need to move heavy data to the drive rapidly without bottlenecks.
Cache type
Both drives use different methods to manage data caching. The GIGABYTE AORUS Gen5 12000 1TB SSD includes a dedicated DDR4 DRAM cache. This separate memory chip helps manage mapping tables and improves consistency under heavy loads. The GIGABYTE AORUS Gen4 7000E SSD does not have a dedicated DRAM cache. Instead, it supports Host Memory Buffer (HMB) technology, which uses a small portion of your system’s main RAM. While HMB is effective for many users, a dedicated DRAM cache is generally preferred for high-end performance and stability in demanding workloads.
NAND technology
The internal flash memory differs between the two models. The GIGABYTE AORUS Gen5 12000 1TB SSD utilizes 232-layer NAND. This high layer count allows for greater density and improved performance characteristics. The GIGABYTE AORUS Gen4 7000E SSD is described as using 3D TLC NAND flash. While TLC is a reliable and common type for high-speed SSDs, the specific layer count is not provided in the data. The Gen5 drive’s 232-layer NAND represents a more advanced manufacturing process, which often correlates with better efficiency and speed potential compared to older NAND technologies.
Which SSD matches your specific needs
Users with PCIe 5.0 motherboards
You need the highest possible bandwidth. This drive delivers up to 11700 MB/s read speeds via PCIe Gen5. The included heatsink manages heat from the 232-layer NAND. You get dedicated DDR4 DRAM cache for consistent performance during heavy workloads.
Owners of PCIe 4.0 systems
Your motherboard likely supports PCIe Gen4. This drive uses that interface for reliable high-speed transfers. It uses Host Memory Buffer technology to save space while maintaining good throughput. It is a stable choice for standard gaming and creative tasks.
Those wanting included cooling
Thermal management matters for sustained writes. This model comes with a heatsink included in the box. It covers the 232-layer NAND chips to prevent throttling. You do not need to buy a separate cooler. This simplifies installation on compatible motherboards.
