Introduction

The Seagate Barracuda ES family represents the third generation of Seagate SATA drives that officially target the entry-level server market where cost and high capacity outweigh raw IOps performance requirements.

Leveraged from the first 3.5" design to incorporate perpendicular recording (the desktop-oriented Barracuda 7200.10), the Barracuda ES manages an impressive flagship capacity of 750 gigabytes delivered across four platters. Seagate specs the ES with an 8.5 millisecond seek time and equips the majority of the family with a 16-megabyte buffer, though less-capacious members are also available with a smaller, 8-megabyte cache. As always, the firm backs the drive with a 5-year warranty.

Seagate has dropped the "NL35" designation, a brand initially established as an enterprise-oriented alternative to the consumer-targeted "Barracuda 7200" series. After a year of marketing the 400 GB NL35 and 500 GB NL35.2, however, the company felt that it was leaving behind a name that carries weight and signifies quality in the business sector.


Top of the driveAs a result, Seagate has chosen to revive the Barracuda name for its nearline class of drives with an "ES"suffix, presumably signifying the drive's EnterpriSe orientation. Seagate aficionados may recall that the original Barracuda drives, of course, featured SCSI interfaces and that the final two 36 GB models of that venerable series were called the "ES" and "ES2" to differentiate them from the then recently-introduced ATA series. Obviously, today's Barracuda ES shares little in common with the old SCSI ES except the name... this ES features over 20 times the capacity, after all!


The following performance tests feature the Barracuda ES and other similar SATA drives with NCQ enabled. One can usually toggle SATA NCQ functionality via the controller's driver interface. In the past, we have presented results for drives with NCQ enabled and disabled as not all SATA controllers supported the feature. These days, however, NCQ-enabled controllers are the rule and not the exception.

Let us see how the 750 gigabyte ES stacks up against the following:

Hitachi Deskstar 7K500 (500 GB) Previous-generation consumer-oriented unit
Maxtor MaXLine Pro (500 GB) Previous-generation competing unit
Seagate NL35.2 (500 GB) Predecessor of the review drive
Western Digital RE2 (500 GB) Previous-generation competing unit
