How many iops in a 15k drive

The former are better for sequential transfer and high capacity requirements. Midline drives are more resistant to rotational and operational vibration, so they are better suited for use in multi-drive configurations. HP Midline drives are for high-capacity applications such as external storage that may require increased reliability.

Like Entry drives, however, Midline drives are for use in moderate workload environments. We do not recommend Entry or Midline drives for mission-critical applications.

They are for mission-critical applications such as large databases, e-mail servers, and back-office. From a value point of view, one can often get better real world performance out of more SATA 7. You'll notice that larger buildouts like Backblaze use SATA and that's because the value is so much better and if you use multiple SATA drives, the performance can match for typical storage loads.

For example, the 1TB 7. Sequential read IOPs should be higher due to buffering at the server, adapter, raid card or controller as well as drive.

Most drives today have some amount of read cache even some of the lower cost SATA drives. Something else that will impact the IOPs are how much concurrency or activity being sent to the drive, granted the drive has to be able to support the activity.

Otoh, a drive that can support more IOPs may not be being pushed due to how much concurrent work being done. Other factors and considerations include the OS, queue depths, driver config, interface e.

Of course your millage will vary For a 10K disk, the expected aproximate range would be Sign In. Turn on suggestions.

How could we possibly know that? Thanks, I will look into it a bit more. It more more of how much performance difference would one see if you had the exact same SAN but 1 with 15k disks and 1 with 10k Thanks all for your suggestions. I will look into the SSD caching over the 15k disks.

It more more of how much performance difference would one see if you had the exact same SAN but 1 with 15k disks and 1 with 10k Also no way to tell.
