Disk Information

Information

Description

Disk Health Status

The general health status of the disk

  • Good: The disk is healthy.

  • Warning: QTS has detected an error. Run a full S.M.A.R.T. test and a disk scan.

  • Error: QTS has detected a critical error. You must replace the disk immediately.

Manufacturer

The manufacturer of the disk

Model

The disk model

Disk Capacity

The capacity of the disk, in both binary and decimal formats

Note:

  • Binary format assumes that 1 GB = 1,073,741,824 bytes. This is the true capacity of the disk and is used by computers and operating systems such as QTS.

  • Decimal format assumes that 1 GB = 1,000,000,000 bytes. This format is used by disk manufacturers and appears in advertising, on the disk's box, and in the disk's hardware specifications.

  • Due to differences in the number of bytes per gigabyte, a disk's binary capacity will be slightly lower than its decimal capacity. For example, a disk advertised as 500 GB (decimal) has a true capacity of 456 GB (binary).

Bus Type

The interface that the disk uses

Supported Bus Types

The disk types the drive bay supports. For example, an internal M.2 SSD slot might support SATA and NVMe SSDs.

Status

The hardware status of the disk

Current Speed

The speed at which the disk is connected to the enclosure

Maximum Speed

The maximum transfer speed supported by the drive bay or slot that the disk is installed in

Temperature

The current temperature of the disk

Disk temperature is retrieved from the disk's firmware using S.M.A.R.T.

Disk Access History (I/O)

  • Good: QTS has not detected any I/O errors on the disk.

  • Error: QTS has detected one or more I/O errors on the disk.

Disk SMART Information
Important:

If any of the S.M.A.R.T. attribute values reach the threshold set by the disk manufacturer or a predefined threshold determined by QTS, this field will change to Warning.

Estimated Life Remaining

The remaining life of the disk, as calculated by the disk's firmware. When the value reaches 0, you should replace the disk.
