Seagate Savvio 10K.1: ST973401SS – 73GB

 

It’s a kind of a rule that no HDD review can be done without Seagate’s products. After all, it was the Seagate Savvio 10K.1 series that first implemented a spindle speed of 10,000rpm and a SAS interface in the 2.5-inch form-factor. The recording density used to be very low then. This 73GB model has two platters to deliver its storage capacity.

After a while, Seagate introduced the Savvio 10K.2 series with double recording density. The senior model now had a capacity of 146GB.

At about the same time as the 10K.2, Seagate released its first series of compact HDDs with a spindle rotation speed of 15,000rpm which was appropriately named Savvio 15K.1. Of course, the increased speed of the spindle did not come for free. The recording density had remained the same as that of the previous-generation 10,000rpm products, so the dual-platter model offered 73GB only. You just can’t have all at the same time. At each stage of technological progress the manufacturers have to balance between high spindle speed and high recording density (i.e. storage capacity). And users have to define their disk subsystem requirements clearly and realize that they have to compromise.

Again we have to admit that we don’t have the full selection of products in our today’s test session. Talking about Seagate’s models, we don’t have those of the three newest series. These are the 10K.3 (it has the same specs as the 300GB Hitachi), the 15K.2 (two times as large as its predecessor in terms of storage capacity), and the recently announced Seagate Constellation, which is a representative of the new breed of HDDs – 2.5-inch drives with a SAS interface but with a spindle rotation speed of 7200rpm.
