Interface and speed comparison
Interface type
The Intel 660p 1TB NVMe M.2 SSD uses a PCIe NVMe 3.0 x4 interface. This allows for direct communication with the CPU, bypassing the traditional SATA bottleneck. The Intel D3-S4510 240GB 2.5-Inch SATA SSD relies on a SATA 6Gb/s interface. This older standard connects through the motherboard chipset. The NVMe connection in the 660p offers significantly higher bandwidth potential. This makes it better suited for modern systems that support M.2 slots. The SATA drive remains compatible with older hardware that lacks NVMe support.
Sequential speeds
Sequential read and write speeds define how fast large files transfer. The Intel 660p 1TB NVMe M.2 SSD achieves 1800 MB/s for both reads and writes. The Intel D3-S4510 240GB 2.5-Inch SATA SSD does not list specific speed figures in the provided data. However, SATA drives are generally capped near 550 MB/s. The 660p’s published 1800 MB/s rate is roughly three times faster than typical SATA limits. This difference is noticeable when copying large video files or game assets.
Storage capacity
Capacity determines how much data you can store. The Intel 660p 1TB NVMe M.2 SSD provides 1 TB of space. The Intel D3-S4510 240GB 2.5-Inch SATA SSD offers 240 GB. The 660p holds more than four times the data of the D3-S4510. This makes the 660p a better choice for users with large media libraries or extensive game collections. The D3-S4510’s smaller capacity limits its usefulness as a primary drive for modern workloads.
Form factor
Physical size affects installation options. The Intel 660p 1TB NVMe M.2 SSD uses an M.2 2280 form factor. It is a small stick that plugs directly into the motherboard. The Intel D3-S4510 240GB 2.5-Inch SATA SSD uses a 2.5-inch form factor. It requires a SATA data cable and a power connection. The M.2 drive saves space and reduces cable clutter. The 2.5-inch drive is easier to install in older desktop cases or laptops with dedicated drive bays.
NAND type
NAND flash type impacts endurance and performance consistency. The Intel 660p 1TB NVMe M.2 SSD uses QLC (Quad-Level Cell) 3D NAND. QLC stores four bits per cell, offering high capacity at lower costs. The Intel D3-S4510 240GB 2.5-Inch SATA SSD uses TLC (Triple-Level Cell) 3D NAND. TLC stores three bits per cell and typically offers better endurance than QLC. The D3-S4510 may be more suitable for heavy write workloads, while the 660p prioritizes capacity.
Which Intel SSD fits your needs best
Users needing large storage for modern systems
The Intel 660p offers 1TB of space, which is significantly more than the 240GB option. It uses PCIe NVMe 3.0 x4 for faster data transfer. This drive suits those who store large files or games. The M.2 2280 form factor fits directly into motherboards. You get high capacity without needing extra cables or drive bays.
Budget buyers with older SATA-only computers
The Intel D3-S4510 uses a standard SATA 6Gb/s interface. This ensures compatibility with older desktops and laptops that lack M.2 slots. The 2.5-inch form factor is widely supported in legacy systems. While capacity is lower at 240GB, it provides a reliable upgrade path for basic computing tasks without requiring new hardware.
Those prioritizing speed and modern connectivity
Speed matters for quick file transfers and system responsiveness. The 660p delivers 1800 MB/s read and write speeds. This is much faster than the SATA limit. The NVMe protocol reduces latency by communicating directly with the CPU. If you have a modern motherboard, this drive maximizes performance potential for everyday applications and media editing.
