300 GB SATA II internal SSD

The Intel 320 Series SSDSA1NW300G301 is a 300 GB solid-state drive built for consumer PCs. It uses a SATA II interface and an Intel controller with 25 nm MLC NAND. The drive targets users who want faster boot and application load times without moving to a newer interface.

SATA II interface and 25 nm MLC NAND

The drive connects through a SATA II port and is fabricated with 25 nm compute-quality MLC flash. Sequential reads reach 270 MB/s and sequential writes reach 220 MB/s. Random 4 KB performance is rated at 39,500 IOPS for reads and 23,000 IOPS for writes.

Low heat silent operation and AES 128 encryption

With no moving parts the SSD runs silently and produces minimal heat in normal use. Full-disk encryption uses AES 128 bit technology and enhanced power-loss management protects data during unexpected shutdowns. Mean time between failures is rated at 1,200,000 hours.

Questions about this item

What does the 39,500 IOPS random 4 KB read figure mean once the drive is installed in a real machine?

It shows how quickly the Intel 320 Series can fetch small blocks of data during typical workloads such as booting the OS or launching applications.

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

The SATA II link limits sequential throughput to 270 MB/s reads and 220 MB/s writes regardless of the NAND speed.

The height is listed as 5 mm — what does it physically need to fit or mount?

A standard 2.5-inch drive bay or caddy that accepts a 5 mm thick SATA SSD.
