Intel 520 Series 480GB SSD

The Intel 520 Series Cherryville is a 2.5-inch internal solid-state drive with 480GB capacity. It uses MLC flash memory and a SandForce controller to deliver consumer-grade performance. The drive fits standard SATA drive bays with a 9.5mm height.

SATA III 6.0 Gb/s interface

The drive connects through a SATA III interface rated at 6.0 Gb/s. On this interface it reaches up to 550 MB/s sequential read and up to 520 MB/s sequential write. On a SATA II link the same drive tops out at 280 MB/s read and 260 MB/s write.

480GB capacity and endurance

The 480GB capacity provides space for operating system, applications and active project files. Random performance reaches up to 50,000 IOPS read and 42,000 IOPS write for mixed workloads. MTBF is rated at 1,200,000 hours and the drive operates from 0°C to 70°C.

Questions about this item

Should I choose the 480GB MLC version or a smaller capacity for my SATA III system?

The 480GB model uses MLC NAND and delivers up to 550 MB/s sequential read and 520 MB/s sequential write on SATA III, plus 50,000 IOPS random read and 42,000 IOPS random write, making it the highest-capacity option in the 520 Series with full SATA III speed.

What do the 550 MB/s read and 520 MB/s write figures mean once the drive is installed in my PC?

Those are maximum sequential speeds over a SATA III link; real-world throughput depends on your controller, cable quality, and workload, but typical large-file transfers will approach the rated 550 MB/s read and 520 MB/s write when the port runs at 6.0 Gb/s.

The drive uses a SATA III interface — what does that cap in practice?

SATA III caps the link at 6.0 Gb/s, so sequential transfers cannot exceed roughly 550 MB/s read or 520 MB/s write; random 4K performance reaches up to 50,000 IOPS read and 42,000 IOPS write within the same interface limit.
