Sandisk SDSSDHII-240G-G25 (SDSSDHII240GG25, SDSSDHII 240G G25, SDSSDHII/240G/G25, sdssdhii-240g-g25) 240GB Ultra II SATA III 2.5 Internal SSD 

Store and access up to 240GB of your data, be it movies, photos, music, documents, or other files, with the 240GB Ultra II SATA III 2.5" Internal SSD from SanDisk. It is equipped with a SATA III 6 Gb/s interface that fits into your system's 2.5" / 7mm drive bay, and provides load and access times for files and programs that are faster than those of a traditional spinning hard drive. In terms of speed, this drive offers sequential write speeds of up to 500 MB/s, sequential read speeds of up to 550 MB/s, random writes of up to 83,000 IOPS, and random reads of up to 91,000 IOPS. In addition to its enhanced data transfer rates, this drive also offers a life expectancy of 1.75 million hours MTBF, nCache 2.0 technology, NCQ support, TRIM support, DevSleep, dynamic and static wear leveling, thermal throttling, and S.M.A.R.T. support.

With solid state drive technology, you benefit from load and access times for your files and programs that are faster than a conventional 7200 rpm hard drive. As SSDs have no moving parts, they are also more durable than traditional hard drives and are better protected against damage from drops and bumps. Having no moving parts also means that SSDs receive less wear and tear, as there are no read or write heads for the drive media to come into contact with. SSDs also help to deliver improved battery life and cooler operating temperatures.

Accelerate Your System with Read Speeds up to 550 MB/s

  • Get sequential read speeds up to 550 MB/s for improved startup and overall performance. Load and run applications, games, videos, and photos more quickly so you can spend more time doing and less time waiting.

Enhanced Speed Technology

  • nCache 2.0 technology helps optimize performance by writing everything into the drive's high-speed buffer before transferring it to the flash array. This architecture helps enables faster burst speed, and allows the drive to achieve sequential write speeds of up to 500 MB/s.

Durable Solid State Design

  • With no moving parts, the SanDisk Ultra II SSD is engineered to resist shock and vibration, helping to keep your data safe even if you drop your computer.

SanDisk SSD Dashboard

  • The SanDisk SSD Dashboard gives you real-time visibility into how your drive is performing. It includes cloning software to help you set up your new drive, tools for disk analysis, and alerts for firmware updates.

A More Efficient Drive

  • SanDisk SSDs are cool, quiet, and efficient, so your laptop battery lasts longer on a single charge.

NCQ Support

  • NCQ support manages the queue length for better multitasking and workload management.

TRIM Support

  • TRIM support and Background Garbage Collection free up unallocated blocks that once held data to help lower latency and boost performance.


  • DevSleep helps to further reduce power consumption.

Dynamic & Static Wear Leveling

  • Dynamic and static wear leveling help make the drive last longer.

Thermal Throttling

  • Thermal throttling helps protect critical drive components against extreme high temperatures to enable data integrity


  • S.M.A.R.T. support monitors the health of your SSD in real time to help prevent data loss.
