Pros & Cons

Pros

✓ 480GB fits Windows, apps, and a small game library on one drive
✓ 550MB/s read and 500MB/s write saturate the SATA 3.0 6 Gb/s link
✓ nCache 2.0 sustains write speed during heavy multitasking
✓ Standard 2.5-inch form factor drops into most laptop and desktop bays

Cons

✗ 2.5-inch only - no M.2 slot option for slim laptops
✗ Write speed (500MB/s) trails read speed (550MB/s)

Manufacturer description

The SanDisk Ultra II 480GB SSD is a 2.5-inch SATA III drive built for turning an aging laptop or desktop into something that boots without the wait. It runs on the SATA Revision 3.0 (6 Gb/s) interface, so it drops straight into any standard 2.5-inch bay, and delivers sequential reads up to 550MB/s and sequential writes up to 500MB/s. SanDisk rates it as a performance boost of up to 28x over a traditional spinning hard drive, and the practical difference shows up where you feel it: boot time, application launches, and large file transfers. The drive's nCache 2.0 technology buffers writes to…

Frequently Asked Questions

How fast is the SanDisk Ultra II 480GB SSD?

It delivers sequential read speeds up to 550MB/s and sequential write speeds up to 500MB/s over SATA Revision 3.0 (6 Gb/s). SanDisk rates the real-world uplift at up to 28x versus a traditional hard drive.

Will this SSD fit my laptop?

It uses the standard 2.5-inch form factor with a SATA 3.0 interface, so it fits any laptop or desktop with a 2.5-inch drive bay. It will not fit an M.2-only slot. Check your system's bay type before ordering.

What is nCache 2.0 and does it matter?

nCache 2.0 is SanDisk's write-caching technology on this drive. It buffers incoming writes to hold speed and endurance up when you are multitasking - streaming, downloading, and working at the same time.

Is the Ultra II durable enough for a laptop that travels?

It has no moving parts and SanDisk cites proven shock and vibration resistance, so a drop is far less likely to cost you data than with a mechanical hard drive. It also runs cooler and quieter and draws less power.
