The Seagate Nytro 3332 7.68TB is a SAS solid state drive for servers and arrays. It uses a 12Gb/s link and sits in a 2.5-inch, 15 mm case. Seagate builds the 3332 line with scaled endurance, which means a lower write rating than mixed workload drives and a lot of space per bay.

What scaled endurance gives you

This drive is rated for 1 drive write per day. On 7.68TB, that is 7.68TB of new data each day. It uses 3D eTLC flash. That suits file stores, web content, backups and other jobs that read much more than they write.

What the SED version adds

SED stands for self-encrypting drive. The drive locks its data with a key, so a pulled or stolen drive is hard to read. This is the SED version, and Seagate marks it with 70094 at the end of the model number.

A lot of space per bay

At 7.68TB, a 24 bay shelf holds over 184TB of raw flash. That lets one rack unit replace a stack of hard drives. It also cuts the power and cooling load for the same space.

Find the right last digits

• XS7680SE70084 is the standard version.
• XS7680SE70094 is the SED version, and it is this drive.
• XS7680SE70104 is the FIPS version.
• XS7680SE70114 is the ISE version.

Speed for the capacity

Seagate rates this drive at up to 2,000 MB/s for reads and 1,650 MB/s for writes. Random speed reaches 240,000 reads and 80,000 writes per second. Seagate gives a mean time between failures of 2.5 million hours and five years of limited coverage.

Controller and key checks

• Your bay must take a 2.5-inch SAS drive that is 15 mm thick.
• Check that your controller supports SED features before you rely on them.
• Keep the key records in a safe place. A lost key can mean lost data.
