Seagate Momentus 7200.1: ST910021AS (100GB)

As this review is a debut of Seagate’s 7200.2 series in our tests we will also include a model from the previous 7200.1 series into it for the sake of comparison. Like the other HDDs, it has two platters but the lower recording density limits its maximum capacity to 100GB. The cache buffer is 8MB large.

160GB storage capacity

 
200GB storage capacity

The new 7200.2 series of Seagate’s drives is represented in this test session by two models, 160GB and 200GB in capacity. As you will see later on, the two differ quite a lot in firmware algorithms.

The new series is a worthy opponent to the other brands’ products. Its high-density platters ensure a storage capacity of 200GB in a dual-platter design. The largest-capacity model is equipped with a 16MB buffer, and the others, with 8MB of buffer memory. The interface is SATA 3Gbps. Generally speaking, 7200rpm 2.5-inch HDDs are premium products in each brand’s line-up and the developers try to show their full manufacturing potential in them.

This series includes two versions of HDDs of each capacity that differ in the presence or absence of the letter G at the end of the model name. This letter denotes G-Force Protection technology that shuts the HDD down quickly if the latter falls, thus ensuring additional protection for the stored data.
