Vastly increase system performance by adding a dual mSATA SSD RAID array into any 2.5" SATA HDD application with the 25SAT22MSAT mSATA to SATA adapter.

Utilize the full potential of your SATA III controller, with mSATA SSDs reducing your data transfer bottleneck with file transfer speeds up to 6 Gbps. mSATA SSDs also save you money by reducing your power consumption over regular platter drives.

You can achieve greater SSD capacity, or data redundancy with the Dual SSD controller supporting multiple RAID modes (RAID 0, 1, BIG). The SSD adapter also supports non-RAID operation (JBOD) when paired with a port-multiplying SATA controller, so both drives can be used independent of one another.

Help protect the health of your drive with an open-frame design ensuring maximum heat dissipation.

The 25SAT22MSAT is backed by a StarTech.com 2-year warranty, and lifetime technical support.

Frequently Asked Questions

Troubleshooting

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.

 

Before You Buy

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.

Disapointing

By: Bogdan - 08/05/2017
The electronic board is not fixed in the metal frame at the oposite end of SATA connector and RAID feature is a joke. RAID 0 is 2 times slower than a single drive instead of being 2 times faster! It doesn't worth the money. You will spend 50$ or more for nothing.

Hi, Thanks for your feedback. We're sorry the card did not perform as well as expected. In our testing, we saw closer to 500 MB/s when using 2 drives in RAID-0. We would be happy to discuss and troubleshoot your configuration, please reach out to us by chat, phone, or email using our support site: https://www.startech.com/support Thank you.

Quite Disappointing

By: mixmup - 09/11/2017
I bought this for the RAID feature. It's a joke. I am able to use about half of the available bandwidth of my SATA 3 port. 2 identical Samsung EVO 850 drives as RAID-0 top out at just under 3 Gbps. A single drive performs almost 2 x faster. Using this product represents a waste of about $400AUD Suspect the bottleneck is the crummy J-micron controller.

Fake product

By: nihon79 - 10/12/2018
500 MB/s is the speed of regular ssd. People buying your product expect twice faster speed with RAID 0. This is a fake product unless you tell us that we are wrong and the RAID 0 built with your product can be something closer to 900 MB/s

Works great

By: FFried - 12/16/2018
Used this to install two Samsung 860 evo mSata drives into my 2012 MacBook Pro. Works fine right out of the gate, no problems whatsoever. I have them configured 'RAID 0', which theoretically is the fastest setup, but, Blackmagic speed test shows read/write at ~450 MB/s, no faster than individual disks would be. But the computer feels faster than it did with a single SSD, so possibly the Blackmagic test doesn't perfectly reflect what's actually going on.

Good for Apple Mac computers

By: marty - 12/29/2018
For my SATA external SSD I wanted to try a modern small size RAID Adapter Converter. So I have found the StarTech unit. The initial test with 2 mSATA 500GB SSD showed 2 individual "Drives". Changing to RAID1 was not successful until I formatted each SSD properly to HFSe. After that it was necessary to reformat the Converter. Formatting showed "JMicron RAID1", wich was successful. Afterwards the Converter was usable for backup with the TimeMachine. The "25SAT22MSAT" allows to build an inexpensive , but very small SSD memory up to 2TB. Proper Formatting is the secret!
