Performance Enterprise
Hard drive manufacturers design drives that will perform well for their largest customers, or sets of customers. This is why “classes” of drives exist.
| Performance Enterprise | |
|---|---|
| Power On Hours | 24 hrs/7 days (8760 POH) |
| Write / Read Ratio | 60/40 |
| Block Sizes | Random |
| Seek Profile | RAID Striped w/Parity |
The “Performance Enterprise” class of drives represents the manufacturer's offerings where throughput, I/O (input/output) performance, and reliability are the highest possible given a volume production and pricing business model. Performance Enterprise drives using traditional HDD technology are either 10K or 15K rpm spin rate, SAS interface, and under 2TB in capacity (with most models being under 1TB).
Hybrid HDD/SSD technology has also been introduced in this class, and a growing part of the market is incorporating enterprise solid state drives (SSD). In addition to the snapshot of features below, Performance Enterprise class drives feature very robust componentry throughout their design.
