Dell Constellation.2 SAS drives

This set contains ten new 2.5-inch internal hard drives from the Dell Constellation.2 line. Each unit delivers 500GB of storage on a SAS 6Gb/s interface spinning at 7200RPM with a 64MB cache. An R-series caddy is included with every drive for direct installation.

Suits PowerEdge server fleets

Administrators refreshing compatible Dell PowerEdge rack, tower or blade models such as the R610, R720, T410 or M610 will find these zero-hour drives a direct fit. Systems that lack a SAS backplane or HBA cannot use these disks.

Interface is SAS 6Gb/s

The 6Gb/s SAS connection is the single specification that determines compatibility; a SAS controller or backplane is mandatory for operation. Without it the drives will not be recognised by the host.

Questions about this item

Will the 64MB cache need any firmware updates or replacement over the drive's lifespan?

The 64MB cache is integrated into the drive electronics and has no user-serviceable parts; no firmware updates or cache replacements are required.

What limits the ST9500620SS during sustained 7200RPM operation?

The mechanical 7200RPM media determines the maximum sustained transfer rate; the 6Gb/s SAS interface provides more bandwidth than the platters can deliver.

How much heat and noise does the 2.5" SAS drive produce in all-day use?

As a 2.5-inch 7200RPM SAS drive, it generates typical enterprise-level heat and audible seek noise; the included R Series caddy helps direct airflow in compatible PowerEdge bays.
