Your price

Boost your system performance by enhancing the capacity, speed and security of your data storage. This two-drive M.2 to SATA adapter lets you install two M.2 solid-state drives in a single 2.5” drive bay and configure a powerful RAID array.

Build a RAID array to enhance system performance

The dual M.2 to SATA adapter supports multiple RAID modes (RAID 0, 1, BIG) helping you to achieve greater SSD capacity or data redundancy, depending on your selected RAID mode. 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.

Maximize file transfer speeds

The dual SSD adapter lets you utilize the full potential of your SATA III controller. Using M.2 SSDs in place of a platter drive reduces your data transfer bottlenecks and gives you file transfer speeds of up to 6 Gbps. M.2 SSDs also save you money by reducing your power consumption over regular platter drives.

The M.2 NGFF SATA RAID adapter also provides TRIM support to enhance the stability and performance of your M.2 NGFF SSDs.

Get dependable drive protection

The M.2 to SATA adapter features an enclosed housing that helps protect your NGFF (Next Generation Form Factor) SSD. The added protection gives you peace of mind when you are using your M.2 drives in applications that require an added level of durability such as hot-swap drive bays, or external SATA docking stations.

The 25S22M2NGFFR is backed by a 2-year warranty and free lifetime technical support.


  • Add data redundancy to your system, by adding a mirrored SSD (RAID 1)
  • Increase the storage capacity of your system by adding an additional SSD in a RAID array (RAID 0/BIG)
  • Turn two unused M.2 drives into a regular 2.5in SATA solid-state drive
  • Retrieve/backup data from an M.2 (NGFF) drive using a standard SATA computer
  • Use M.2 drives in any 2.5 in. SATA application

Frequently Asked Questions


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 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

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.

Note: Not all 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 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 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.

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.

Seems like a good idea

By: Julio2r - 07/25/2016
I bought this adapter in hopes to utilize the sata m.2 drives that I had ordered instead of the pcie version. The idea seems like a good one, other than the fact you RAID 0 (2) M.2 drives capable of speeds of up to 540 MB/s and sequential write speeds of up to 500 MB/s to be bottle necked into a 600 MB/s interface? Why RAID for that sliver of performance? The drive seems extremely unstable in my laptop, not sure if it is jostling of being transported about or what ,but I'm having issues maintaining my data on it. I've had the laptop refuse to boot on 2 separate occasions do to "hardware issues", i.e. the drives moving around in their allotted slots or dropping of the partitions all together. Finding it difficult to justify this very expensive set up.

Hello, Thank you for reviewing our 25S22M2NGFFR adapter with RAID. We would like to offer some assistance. You are correct the maximum throughput supported by a SATA III interface is 600MB/s, and it does limit the advantage of using two fast SSDs in RAID 0 over a single SATA III connection. This unfortunately is a limitation of the SATA III standard. The enclosure does also support other RAID modes, including RAID 1 (mirrored), JBOD (Just a Bunch of Disks), and BIG (Spanning or Concatenation). The intermittent issue you’re seeing with the drive disconnecting is certainly not expected behaviour. Are both of the M.2 drives securely screwed into the enclosure, using the posts at the correct length for the specific SSDs you’re using? Also, is there extra space in your laptop’s drive bay that would allow the whole 25S22M2NGFFR to move around and possibly disconnect? We hope this has been helpful. In the event you need further assistance, please do not hesitate to contact support directly using any of the options available on the Support page linked above. Thank you, Customer Support

TRIM command does not pass through to connected SSDs in RAID 0. What is the point of splitting the interface into two SSDs without TRIM. Performance will be poor as times go.

Good adapter - Nice option for older system

By: Macphoto - 07/13/2017
Used this adapter in a fairly new Lenovo computer and found that the speed gains were impressive. This adapter is easy to use. This is partially because it is hard to mess us M.2 installs as they only fit one way. I set the jumpers to span as for this purpose I just wanted one big drive out of the 2 I installed. Everything went without a problem and I was running very quickly. Overall this is a good adapter

Great for M.2 Upgrades

By: Andrew11 - 07/14/2017
I always thought that upgrading a laptop with an M.2 drive would be a long way off, but it seems like you blink and it’s time! Now I don’t have to worry about what to do with that smaller drive, I can hand-me-down to another machine with a standard SATA bay. The adapter itself is very well designed and equipped; you can put any physical size ‘drive’ into either of the 2 slots, and it feels very sturdy and secure. I didn’t bother with the RAID ability since 2 drives suit me just fine, but it’s good to know it’s there available down the road! I received this product in exchange for an unbiased review

JBOD mode just doesn't work

By: Pablomep - 11/15/2018
I was so interested in using two different size, different manufacturer M.2 SSD's in my one SSD slot laptop. I thought it was just plug-and-play, but the second SSD never appeared listed in a windows installation session, even using DISKPART. So I thought it was a configure-first issue, and bought a SATA to USB adapter. Only a waste of money. The device can be configured and seen as SPAN (one large drive made of the sum of the two physical drives) or as individual drives if they're alone in any of the slots, but as soon as they're put together and configured in JBOD mode, only the drive connected in the slot #1 is viewed by the OS. Such dissapointing and a waste of time and money. Bought some time ago, I don't think I can return it

Sam, Customer Support on 11/16/2018 11:59:31 AM
Thank you for your feedback on 25S22M2NGFFR. We apologize that JBOD isn't working for you and want to help. Connecting multiple independent drives over a single SATA connection requires Port Multiplier. If the host SATA port you're connecting 25S22M2NGFFR to doesn't feature Port Multiplier, it will only be able to see a single drive in the enclosure. If you need a SATA controller which features Port Multiplier, we recommend an add-on card such as our PEXSAT32.

Good for Linux and Windows

By: RootAlex - 01/08/2019
This device is good for Windows or Linux computers but for Macintosh it is awful, I bought one and did the raid 0 on two Toshiba 128 gb with APFS and got and average sequential read speed of 8~9mb and 234mb write. But on my Windows I did get read speed of 1400mb and write 240mb.

Could of been great

By: Henmarty - 06/19/2019
I bought this for the sole purpose of running in an external caddy to be ran in jbod mode thinking that i could run drive 1 as an enterprise windows to go drive and to have drive 2 configured with microsoft deployment toolkit with other winpe based tools such a shame this is not possible as this would of been an otherwise excellent product such a shame

Matt, Customer Support on 6/24/2019 11:08:09 AM
We're sorry to hear our 25S22M2NGFFR was not suitable for your setup. For this enclosure to work in JBOD mode, the SATA controller that It's connected to must support Port Multiplier otherwise only one or neither drive will show up. Most external enclosures are designed to use a single drive so they will not have Port Multiplier support.

Does not work with anything but span

By: TW9YLLC - 06/26/2020
been toying this for several days even with the excellent technical support it will let me configure as Span used disk part & 2 different manufactures m.2 drives (2) 256 GB (2) 500GB when I set the raid in jbod mode raid 1 or concentation mode it reboots my PC have tried it on 3 different machines 15 year old machine 9 year old machine & a new machine im building same result it will see a single drive in the other raid modes in either slot but not in jbod or raid1 precisely why I bought these for the raid ability had them a few weeks am waiting for another brand to arrive today 06-26-2020 been purchasing startech products for as long as I can remember this has been a bust & a disappointment lots of hours wasted with no solution

Using hardware switches for RAID levels

By: JohnE - 04/10/2021
I bought this to set up a resilient RAID 1 system, and it works well. However, the only way to confirm it's working is to write to the array, shutdown, remove one drive, reboot and then see if the file you wrote is still there. Then, repeat for the second drive. The problem is that using hardware RAID means there is no way of knowing when one drive has failed - the only time you will know there is a problem is when both drives have failed and then it's too late. What's required is a simple utility program to show the status of the disks in the array. If that were available I'd be very happy with this product and give it 5 stars but now it is much less useful. Because of this I cannot give this a good rating. It works, but I need to know that it works!

By: JohnE2 - 05/07/2021
I have found that the Windows monitoring software for RAIDON GR3380-SB3 also works for this drive. So that solves my problem and I can now give 5 stars.
