Frequently Asked Questions

Before You Buy

Although M.2 SSDs come in similar form factors, only an M.2 SATA drive with an NGFF B key will operate with this device. M.2 drives that are PCIe or have a different key position are not compatible with this device.

This device can adapt an M.2 SATA drive to standard SATA connections, which is not possible for a PCIe based M.2 drive. The key type refers to the connector type on the M.2 SATA drive. B key can be M.2 PCIe x2 or SATA, so it is important that you check the specifications of the drive to see if it supports SATA.

To determine if your hard drive will work in this enclosure, on the product page, click the Technical Specifications tab, and do the following:

  • Make sure that the enclosure supports the storage size of your hard drive. If the storage size of your hard drive is larger than what the enclosure was tested with, the hard drive will likely still work with the enclosure.
  • Confirm that your hard drive uses the same interface type as the enclosure. For example, IDE, SATA, or M.2.
  • Make sure that the enclosure supports the physical size of your hard drive, such as 2.5 inches or 3.5 inches.
  • Make sure that the enclosure supports the height of your hard drive. For example, 9 mm or 15 mm.
  • Verify that the power consumption of your hard drive doesn’t exceed the power output of the enclosure. If you’re using multiple hard drives, make sure that the combined power consumption of all of the hard drives doesn’t exceed the power output of the enclosure.

USB 3.1 is the most recent version of the USB (Universal Serial Bus) standard for connecting computers and electronic devices. It is capable of data transfer speeds up to 10Gbps, and while it can use the USB-C connector type, it can also use a variety of other connector types. To achieve USB 3.1 transfer speeds, your USB host connection, cables, and device must all support USB 3.1. USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). 

USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps).

USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios:

  • USB-B 3.1 cables are not compatible with USB-B 2.0 ports.
  • Unless you use an adapter, USB-C ports or cables will not work with USB-A or USB-B ports or cables.
  • Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or USB 2.0, or you might experience lower transfer speeds and impacted performance.
  • Bus-powered USB devices that requires more power than what USB 2.0 can provide are not compatible with USB 2.0.

To transfer data at speeds of 10Gbps, you need to confirm that the following components in your setup support USB 3.1:

  • The USB host connection
  • The USB cable
  • The USB device and any subcomponents (for example, a hard drive docking station and the hard drives in the docking station)

Note: USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). Devices that support USB 3.1 should have the USB 3.1 symbol on them. If the USB 3.1 symbol does not appear on your USB source or device, refer to the information provided by the manufacturer to confirm whether the USB source or device support USB 3.1.

The included USB cable for this USB 3.1 Gen 2 device has been tested and verified to perform at USB 3.1 Gen 2 speeds of 10Gbps.

USB-C is a type of USB connector that is capable of supporting the following:

  • Data transfer speeds up to 10Gbps, if you use USB 3.1.
  • Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
  • Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.

Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers.
