Seems like a good idea
on July 25, 2016
Posted by: Julio2r
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,

Hugely disappointing
on August 5, 2021

I've been looking at this adapter for some time now and finally decided to buy one together with two Western Digital 1TB M2 blades. I wanted it set up as JBOD so I can just see two 1TB volumes in a MacBook Pro. Both blades will work but only individually. Surely the RAID capability is this adapter's biggest feature but as others have found, it only works with another adapter. Why is this not made clear in your advertising blurb on Amazon? Now I have to repackage everything and get a refund. Abysmal product I'm afraid and Startech needs to up its game and deal with this issue.

Thank you for your feedback. We are very sorry to hear that you are experiencing difficulty with 25S22M2NGFFR.
Please note that in order to use 25S22M2NGFFR in JBOD mode, the SATA controller that It's connected to must support Port Multiplier. Without this feature on the SATA controller, the controller would be limited to seeing only a single drive.

Could of been great

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

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.

Nice RAIDZ and 1 copies!
on September 28, 2021

I already have 2. They're functional.
Haven't put them under significant load yet.
I've got two each with two 256GB SATA m.2 drives, and two additional 500GB SATA SSDs, in a RAIDZ
About what you'd expect. 500MB/sec per link.
I had to put them into RAID0 mode, because SAS doesn't support SATA PMP.
So they wouldn't work as JBODs.
