Overzicht

De S3520BU33ER 2-bay RAID-behuizing biedt een krachtige externe opslagoplossing, waardoor u een veilig RAID-array met twee 3,5” SATA harde schijven kunt bouwen, met de mogelijkheid deze via een beschikbare USB 3.0- of eSATA-poort op uw computer aan te sluiten.

Voor snelle datatransmissie en een efficiënte prestatie van uw SATA III-schijven ondersteunt de RAID-behuizing volledige SATA III-transmissiesnelheden (tot 6 Gbps) en volledige USB 3.0-transmissiesnelheden (tot 5 Gbps). Wanneer de behuizing via USB is aangesloten, ondersteunt de behuizing UASP en werkt daardoor tot 70% sneller dan conventionele USB 3.0, als deze wordt gecombineerd met een voor UASP geschikte hostcontroller (zie onze prestatie hieronder).

De behuizing ondersteunt JBOD, Spanning, RAID 0 en RAID 1 en biedt verschillende mogelijkheden die u in staat stellen uw schijfopstelling naar wens aan uw opslagvereisten aan te passen. 

Voor zowel maximale duurzaamheid als betrouwbaarheid beschikt de externe RAID-behuizing over een kwalitatief hoogwaardige aluminium constructie met een ingebouwde ventilator voor een betere ventilatie en een betere werkomgeving voor uw schijven.

De HDD-behuizing biedt een veelzijdige oplossing om de opslag-/back-upmogelijkheden van uw computer te verhogen en ondersteunt harde schijven met grote capaciteit (getest tot 4 TB).

Om de compatibiliteit met uw computersysteem te garanderen, ondersteunt de S3520BU33ER alle toonaangevende besturingssystemen, inclusief: Microsoft Windows® (8/7/Vista/XP/Server 2008/Server 2003), Apple® OSX (10.9/10.8/10.7/10.6), Linux en Google Chrome OS™.

De behuizing wordt gedekt door een 2-jarige garantie van StarTech.com en gratis levenslange technische ondersteuning.

Verbeterde prestatie met UASP

UASP wordt ondersteund in Windows 8, Mac OSX (10.8 of hoger) en Linux. Uit tests blijkt dat UASP 70% sneller leest en 40% sneller schrijft dan traditionele USB 3.0 bij volle capaciteit.

UASP Speed Diagram

Bij dezelfde volle capaciteit bleek uit de tests dat UASP ook 80% minder processorvermogen nodig heeft.

Veelgestelde vragen (FAQ)

Voor uw aanschaf

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.

Note: Not all StarTech.com devices support each of the RAID modes described below. For more information on the RAID modes that your device supports, refer to the manual or the StarTech.com product page.

Redundant Array of Independent Disks (RAID) is a virtual disk technology that combines multiple physical drives into one unit. RAID can create redundancy, improve performance, or do both.

RAID should not be considered a replacement for backing up your data. If critical data is going onto a RAID array, it should be backed up to another physical drive or logical set of drives.

The following are terms that are normally used in connection with RAID:

  • Striping: data is split between multiple disks.
  • Mirroring: data is mirrored between multiple disks.
  • Parity: also referred to as a checksum. Parity is a calculated value used to mathematically rebuild data.

Different RAID levels exist for different application requirements.

Refer to the following table for the list of RAID modes offered by some StarTech.com products:

RAID mode Description Operation Advantages Disadvantages Recovery
RAID 0 Striped disks Data is split evenly between two or more disks. Large size and the fastest speed. No redundancy. If one or more drives fails, this results in array failure.
RAID 1 Mirrored disks Two or more drives have identical data on them. A single drive failure will not result in data loss. Speed and size is limited by the slowest and smallest disk. Only one drive is needed for recovery.
RAID 3 Striped set with dedicated parity Data is split evenly between two or more disks, plus a dedicated drive for parity storage. High speeds for sequential read/write operations. Poor performance for multiple simultaneous instructions. A single drive failure will rebuild.
RAID 5 Striped disks with distributed parity Data is split evenly between three or more disks. Parity is split between disks. Large size, fast speed, and redundancy. The total array size is reduced by parity. A single drive failure will rebuild.
RAID 10 1+0; Striped set of Mirrored Subset Four or more drives are made into two mirrors that are striped. Larger size and higher speed than RAID-1, and more redundancy than RAID-0. No parity. Only one drive in a mirrored set can fail.
JBOD Just a Bunch Of Disks Any number of drives are accessed independently by the operating system. Software RAID modes can be used. Hardware RAID may have better performance. N/A
Big Spanning or Concatenation Data is written on one drive until it is full, and then the next drive(s) until it or they are full. Creates a very large and simple array.

No redundancy.

N/A
Clone RAID 1 + Spare

Two drives have identical data, plus one drive is used for rebuilding in case of a primary array failure.

Seamless operation when one drive fails in a RAID-1 array. Spare drive is not accessible to the user. Only one drive is needed for recovery.

 

Hoe gaat u te werk

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.

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.

Note: Any data currently on the drives will be lost during this process. You need to back up all of your data before you set a RAID mode.

To set a RAID mode, complete the following:

  1. Use a USB cable to connect the hard drive enclosure to a computer.

Note: Your computer needs to be turned on while completing these instructions.

  1. Turn off the hard drive enclosure.
  2. Set the RAID switch to the RAID mode that you want to set.
  3. Press and hold the Set button and turn on the hard drive enclosure.
  4. When the enclosure is turned on, release the Set button.

Note: When you change the RAID mode again, complete the steps above to set the unit back to JBOD before you set a different RAID mode.

In order to rebuild a RAID array, you need to replace a physical drive with an identical drive on the same RAID controller. Although standard RAID levels are generally agreed upon throughout the industry, the implementation varies between manufacturers. RAID arrays are typically not accessible when they are moved to another controller, and data may be unrecoverable if the drives are out of order or have been formatted or accessed by another RAID controller.

If a RAID controller has failed, you should get the exact same model of RAID controller.  

Note: If a drive or drives were damaged, it is possible that the RAID array may be permanently unrecoverable.

RAID should not be considered a replacement for backing up your data. If critical data is going onto a RAID array, you should back up the data on another physical drive or logical set of drives.

Rebuild a RAID array

With the following RAID modes, recovery is possible using the same StarTech.com product. Refer to the following table for the appropriate method to use to recover your RAID array.

RAID mode Max # of failed drives Procedure
RAID 1 Only one drive is needed for recovery.
  1. Determine which drive is operational by using the RAID management utility (if available) or test each drive individually on a different hard drive controller (for example, a hard drive docking station or SATA controller).

  2. Replace the failed drive with an identical hard drive.

The array will rebuild and is accessible during the rebuilding process.

RAID 3 Single drive failure will rebuild.
  1. Determine which drive is defective by using the RAID management utility (if available) or with diagnosis LEDs on the controller or enclosure.

  2. Replace with an identical hard drive.

Note: Do not change the order of the drives.

  1. The array may be accessible during the rebuild, but you should let the controller rebuild without interruption so that performance is not compromised.

RAID 5 Single drive failure will rebuild.
  1. Determine which drive is defective by using the RAID management utility (if available) or with diagnosis LEDs on the controller or enclosure.

  2. Replace with an identical hard drive.

Note: Do not change the order of the drives.

  1. The array may be accessible during the rebuild, but you should let the controller rebuild without interruption so that performance is not compromised.

RAID 10 Only one drive in a mirrored set can fail.
  1. Determine which drive is defective by using the RAID management utility (if available) or with diagnosis LEDs on the controller or enclosure.

  2. Replace with an identical hard drive.

Note: Do not change the order of the drives.

  1. The array may be accessible during the rebuild, but you should let the controller rebuild without interruption so that performance is not compromised.

 

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 from 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.
