Overview

The S358BU33ERM 8-bay removable hard drive enclosure lets you access eight individual 2.5" or 3.5" hard drives simultaneously using a single eSATA or USB port.

For fast performance and efficient data transfers when connected through eSATA, the HDD enclosure supports full SATA III transfer speeds -- up to 6 Gbps. For universal compatibility, the enclosure can be connected through USB 3.0 with transfer speeds up 5 Gbps plus support for UASP, which supports performance up to 70% faster than conventional USB 3.0 when paired with a UASP-enabled host controller to utilize the full potential of your SATA III hard drives. See our UASP testing results below for further details.

The HDD enclosure supports the fastest drive technologies including SATA III (6 Gbps), hybrid drives and solid state drives (SSD), helping save you time through optimized performance from your external storage devices.

To help protect your drives the HDD/SSD enclosure has a built-in fan that keeps your drives running at optimal temperatures. Plus, the metal drive trays ensure maximum heat dissipation. To ensure compatibility with your computer system, the drive enclosure is OS independent. 

Please note that in order to access multiple drives, the enclosure requires that your host device supports port multiplier. For desktop computers without port multiplier capability, StarTech.com offers the 2 Port PCI Express eSATA Controller Card (PEXESATA2).

Improved Performance with UASP

UASP is supported in Windows 8, Mac OSX (10.8 or above), and Linux. In testing, UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance.

UASP Speed Diagram

At the same peak in testing UASP also shows an 80% reduction in required processor resources.

UASP Speed Diagram

Testing results were obtained using an Intel® Ivy Bridge system, a UASP-enabled StarTech.com Enclosure, and a SATA III solid state drive.

The S358BU33ERM is backed by a StarTech.com 2-year warranty and free lifetime technical support.

The StarTech.com Advantage

  • Versatile connectivity options, through either USB or eSATA
  • Maximize performance, with SATA III file transfer speeds up to 6Gbps using eSATA
  • Save time, with file transfers up to 70% faster than traditional USB 3.0 when used with a UASP-supported host

Frequently Asked Questions

Before You Buy

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.

How to

To confirm that the Mac OS detects your USB device, complete the following:

  1. Click the Apple icon.
  2. Click About This Mac.
  3. Click More Info or System Report.
  4. Under the appropriate heading, confirm that your USB device is listed and that there isn't an error. For example, a network card would be under Ethernet Cards.

You may need to refresh the System Information page after you plug in your device.  To do so, press Command R with the System Information page open.

Your USB device is listed according to the name of the chipset. To determine the name of the chipset of your USB device, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.

Troubleshooting

SATA hard drive controllers require a feature called port multiplier to read more than one hard drive per SATA or eSATA port. The port multiplier feature is not standard on many SATA hard drive controllers.

If your computer is only recognizing one of your hard drives, you need to plug the eSATA cable into a SATA controller that includes the port multiplier feature. If none of your current hard drive controllers include this feature, you can add a hard drive controller that does support port multiplier in any available expansion slot (for example, PCI, PCI-Express, PCMCIA, CardBus, or ExpressCard). StarTech.com has hard drive controllers available that support the port multiplier feature. To view the hard drive controllers, click here: http://startech.com/Cards-Adapters/HDD-Controllers/SATA-Cards/?filter_PORTMULTIPLIER=Yes.

If you have a hard drive controller card that does support the port multiplier feature but it is only reading one hard drive at a time, update the drivers of the hard drive controller. To find the most current StarTech.com drivers, click here: http://www.startech.com/Support.

When you troubleshoot issues with a hard drive enclosure, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Cables
  • Hard drives
  • Hard drive enclosure

To test your setup components, try the following:

  • Use the cables, hard drives, and hard drive enclosure in another setup to see if the problem is with the components or the setup.
  • Use a different cable, hard drive, and hard drive enclosure in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test the hard drive and hard drive enclosure, it is recommended that you do the following:

  • To check Disk Management, press the Windows key + R, type diskmgmt.msc, and press Enter. Check to see if your hard drive is listed.
  • If the hard drive is listed with unallocated space, the hard drive needs to be reformatted. Right-click unallocated and click New Simple Volume. Follow the on-screen instructions to complete the reformatting.​

Note: Formatting a hard drive erases all of the data on it. Make sure that you back up all of your data before you reformat the hard drive.​

  • If the hard drive is listed as healthy but does not have a drive letter, for example, C:, right-click healthy and click Change Drive Letter and Paths. Click Add, assign a drive letter, and click OK.

Note: A formatted hard drive will not show up in Computer or My Computer until it has a drive letter assigned to it.

You should not upgrade your device's firmware if you do not have any issues with the functionality of your device. The only time you should consider an upgrade is if you are experiencing a problem with the device, and you have confirmed that the firmware addresses this problem.  You can confirm this is the case by reviewing the documentation included with the firmware or by consulting with our Technical Support team. Incorrectly upgrading firmware can result in diminished performance so it is best to contact StarTech.com if you would like to perform this operation.
