256GB SATA III MLC Internal SSD
The Crucial RealSSD C300 is a 2.5-inch internal solid-state drive with a 256GB capacity. It connects through a SATA 6Gb/s interface and uses Micron MLC NAND flash with a Marvell controller. The drive delivers sustained sequential reads of 355MBps and writes of 215MBps on a SATA 6Gbps link.
Suits 2.5-inch SATA bays needing MLC endurance
This drive fits laptops and desktops with a standard 2.5-inch SATA bay. The MLC memory and 1,200,000-hour MTBF serve workloads that value write endurance and reliability. Systems limited to SATA 3Gbps will see reads capped at 265MBps, while builds requiring an M.2 form factor or a different capacity cannot use this model.
355MBps SATA 6Gbps sequential read
The headline figure is a sustained sequential read of 355MBps when the host runs SATA 6Gbps. That number decides whether the drive meets the throughput target for a given workload. On a 3Gbps port the read drops to 265MBps, and write throughput stays at 215MBps regardless of link speed.

คำถามเกี่ยวกับสินค้านี้
Will this 2.5 inch SATA III SSD fit in a standard 2.5 inch drive bay or laptop caddy?
The drive measures 3.95 inches wide by 2.75 inches deep by 0.37 inches high, matching the standard 2.5 inch form factor for internal bays and caddies.
Does the SATA III interface work on an older motherboard with only SATA 3Gbps ports?
Yes, it is backward compatible; sustained sequential read drops to 265MBps on a 3Gbps port while write stays at 215MBps.
How can I verify the drive is healthy and performing at its rated 60000 read IOPS after installation?
Use a SMART monitoring tool to check the health status and run a 4k random read benchmark to confirm speeds near the 60000 IOPS specification.
