Intel 320 Series 40GB SATA II SSD

This Intel 320 Series drive is a 2.5 inch internal solid-state drive with a 40GB capacity. It connects via a SATA II interface and uses MLC NAND flash memory built on a 25nm process. The drive includes a height of .3 inches and weighs 2.89 oz.

Suits older SATA upgrades.

This SSD suits users upgrading older laptops or desktops limited to a SATA 300 interface. The 40GB capacity fits a boot drive for a lightweight operating system. Buyers needing more storage space or faster sequential transfer rates should look at larger or newer drives.

SATA II interface with 200 MB/s maximum read

The single specification that decides fit is the SATA II interface rated at 300 MB/s. Maximum read transfer rate reaches 200 MB/s while maximum write transfer rate reaches 45 MB/s. Random 4 KB reads hit 39,500 IOPS and writes hit 23,000 IOPS. Full disk encryption uses AES 128 bit technology.

Questions about this item

Which capacity should I choose for the Intel 320 Series SSD?

The Intel 320 Series is available here in a single 40 GB capacity, built with 25 nm Intel MLC NAND flash memory.

What does the 39,500 IOPS random read figure mean in everyday use?

It shows the drive can handle up to 39,500 small 4 KB read operations per second, speeding up OS boot, application launch and multitasking compared with a mechanical hard drive.

What does the SATA/300 interface limit in practice?

The SATA II 3 Gb/s link caps sequential throughput at roughly 300 MB/s, so this drive reaches its rated 270 MB/s read and 220 MB/s write without hitting the interface ceiling.
