Frequently asked questions

What are the sequential read and write speeds of the Crucial m4 128GB?

The CT128M4SSD2 delivers sustained sequential read speeds up to 500MB/s and write speeds up to 175MB/s using the SATA 6Gb/s interface. These speeds represent a significant improvement over mechanical hard drives, enabling faster boot times and application launches. Random read performance reaches 45,000 IOPS for responsive system behavior during multitasking.

Is the Crucial m4 compatible with my laptop or desktop?

Yes. The m4 uses a standard 2.5-inch SATA interface found in most laptops and desktops manufactured in the last 15+ years. The 9.5mm height accommodates standard drive bays. Crucial offers installation kits with USB-to-SATA cables and data transfer software for easy migration. Verify your system has a 2.5-inch SATA bay or 3.5-inch adapter bracket availability.

What type of NAND flash does the m4 use and why does it matter?

The m4 uses Micron's high-speed synchronous MLC (Multi-Level Cell) NAND flash technology. MLC provides better endurance and reliability than SLC while offering higher capacity density than SLC. This makes the m4 suitable for intensive consumer and professional workloads requiring consistent performance and data durability over extended periods.

How much power does the Crucial m4 consume compared to a hard drive?

SSDs consume significantly less power than mechanical hard drives due to the absence of moving parts. The m4's low power consumption extends battery life in laptops and reduces cooling requirements in desktop systems. Exact power specifications vary by workload, but typical idle consumption is under 100mW with active read/write operations drawing proportionally more.

What operating systems does the m4 support?

The Crucial m4 is compatible with Windows, macOS, and Linux operating systems. As a standard SATA drive, it requires no special drivers or firmware beyond what the OS provides natively. The drive works with any system featuring a 2.5-inch SATA interface, making it universally compatible across consumer and professional platforms.

Does the m4 come with installation accessories?

The base CT128M4SSD2 model includes the SSD only. Optional variants are available: CT128M4SSD2CCA includes data transfer software and USB-to-SATA cable for laptop installation; CT128M4SSD2BAA includes a 3.5-inch adapter bracket and SATA cable for desktop integration. Check your system requirements before purchasing to determine which bundle suits your installation needs.
