Capacity and interface

The Crucial MX300 CT275MX300SSD1 is a 275GB internal solid state drive built for consumer laptops and desktops with a 2.5 inch SATA III interface. It uses Micron 3D NAND memory components to deliver solid-state responsiveness for everyday computing tasks. The 7mm height fits standard drive bays and slim chassis alike.

Sustained load behaviour

Sequential reads reach up to 530 MBps and writes up to 500 MBps on all file types while random performance holds at 92,000 read IOPS and 83,000 write IOPS. Dynamic Write Acceleration maintains faster saves and file transfers during prolonged workloads. The drive operates reliably across a 0°C to 70°C temperature range.

Build quality and daily implications

A 1.5 million hour MTBF rating and over 90x greater energy efficiency than a typical hard drive point to durable operation with minimal heat output. The SATA III connector and standard 2.5 inch dimensions allow direct replacement of mechanical drives without adapters. Acronis True Image HD compatibility on Windows simplifies migration and backup routines.

Questions about this item

How much power does the MX300 275GB draw compared with a mechanical drive when it runs continuously?

The drive is over 90x more energy efficient than a typical hard drive, so it adds very little heat or power load during all‑day operation.

What connection does my motherboard need to run this CT275MX300SSD1?

A standard SATA III port and a matching SATA power cable from the PSU are all that is required.

Will the 7.00 mm height fit in the same 2.5 in bay I use for my old laptop hard drive?

Yes, the 7.00 mm thickness matches the common 2.5 in form factor used by most notebook HDDs.
