I'm going to wait to see what the Mac mini 5 new features are but I might replace my Studio with an M5 Studio. This would make for some nice, fast storage.
I don't really get this, as it competes directly with their very own Envoy Ultra, which is also a TB5 drive. Maybe it's just that the 1M2 is more easily user serviceable ie, its an enclosure rather then a complete drive, unlike the Envoy Ultra which comes as a complete 'sealed' unit (even though it can also be easily opened via 4 screws and SSD replaced/upgraded)......
Either way the 1M2 are fantastic drives - I have a couple of 8TB units that I may be tempted to sell in order to upgrade to the faster drives!
I would only get the empty enclosures though - especially if OWC still prefer to use the Aura IV drives, which are from 2022 and starting to show their age a little......stick a 990Pro or a SN850X into these enclosures and they fly!!
I think that OWC has sold a ton of the 1M2 enclosures as they generally get rave reviews at Mac forums that I visit.
They are also really nice if you have, say, an M1 Max Studio with an OWC 1M2 and a Samsung 990 Pro and you upgrade to an M4 Max Studio. If you really want TB5, you can just buy the enclosure and move the 990 Pro from the TB4 enclosure to the TB5 enclosure and then sell or repurpose the TB4 enclosure.
You could make the case that they don't need the Envoy Ultra anymore too, as they usually give you more storage options on the 1M2.
Maybe more for the mobile market where these things will be moved around lot and placed in laptop carrying backs where stuff can get in. Its odd, because we're not talking about a hard drive with spinning platters where dust can cause a head crash. I think its more marketing then anything else. As for the cable its, not soldered into the logic board, its replaceable if the need arises. I watched a teardown and while its unnecessary, its not the end of the world to replace it. My use case is such that it sits on my desk and doesn't move.I guess you could also say the Envoy Ultra is for a slightly different target market - it's a IP67 sealed unit with a 'built-in' cable, so its waterproof and dustproof etc - ie, more hardwearing.
I recently bought one of these for use with a Samsung 990 Pro 4TB and am getting around 6000+ MB/s transfer speed between it and my Mac Mini M4 Pro's internal storage using a rear TB5 port 👍🏻 Very pleased.
The Samsung does test the best IMO, but I wanted a higher capacity so went with the 8TB WD SN850x.
Apparently the WD drives run a bit cooler than the Samsung, and hold longer before any throttling kicks in during really heavy usage. But I doubt you'd notice in day to day usage, unless you're really doing large file transfers.
Just passing along what I read in a different place some time back. I was told Thunderbolt 5 certification needs to be given based on the device with the drive inside of it that it will be sold with. Therefore, an enclosure that has TB5 capabilities but is sold without a drive is likely to be labeled USB 4 V2, not TB5, but an enclosure with the drive inside as sold may be labeled TB5.
I'm curious how the SSD temp.s will compare to the Envoy Ultra. The review Ifti linked for us sounds good on thermals.
Ah that's good to know, thanks!
I rarely measure temps TBH - I like to just go ahead and use the drive in my daily setup (mainly for editing via FCPX). I have had absolutely no issues with the Envoy Ultra or the 1M2.
What I have noticed is my original 1M2's (40Gbps versions) do run hot to the touch - I can put my hand on the top after some editing and exporting, and it physically feels very hot - not caused any issues and no throttling that I have noticed, but enough for me to feel uncomfortable enough put my desk fan on over them for a few minutes at times! This isn't a bad thing - it shows the heatsink is doing its job in drawing heat away from the SSD and dissipating to the outside.
On the flip side, the 1M2 80Gbps as well as the Envoy Ultra hardly heat up at all - was quite surprising - barely warm to the touch after the same use (and that using the same internal drive in the 1M2)......they hardly seem to break a sweat!
For those after more storage, or a RAID solution with multiple SSDs, OWC have also just updated their 4M2 enclosure too. This time round though, the fans only ramp up when needed - unlike the previous version they do not stay on all the time (I've never heard them spin up at all in fact, thanks to the internal heatsink). So this is another great drive - although its a USB4 enclosure at 40Gbps. I would have loved a TB5 version of this drive, but your explanation RE the TB5 certification going on a complete drive solution makes sense - either way, an 80Gbps version of this 4M2 would be great! Hopefully it'll come next!
I mean, look at the size of the internal heatsink in this thing!
That is a really neat device. A few issues to note:For those after more storage, or a RAID solution with multiple SSDs, OWC have also just updated their 4M2 enclosure too.
That is a really neat device. A few issues to note:
1.) The version without SoftRAID is roughly $240, but with it roughly $380 direct, and while Apple offers a free Apple RAID option, from what I've read before and hardly recall I got the impression many people would prefer SoftRAID. Still, for an enclosure that can hold 4 SSDs, not bad!
2.) Holding 4 SSDs and with the RAID option, the question which be which RAID version. I think most would opt for RAID 5, so if you use 4 SSDs you effectively get to use 3 with the capacity of 1 sacrificed for 'parity' (redundancy; so if 1 SSD fails, you can replace it without losing any of your data - but if 2 SSDs fail you lose it all).
3.) Which creates a problem. With most RAID arrays, the RAID system treats all discs as though they had the same capacity as the smallest of them. So, if you had 4 discs (SSDs here, but could be HDDs in a different unit), and their capacities were 1 terabyte, 4 terabyte, 4 terabyte and 4 terabyte, the RAID would treat them all as having 1 terabyte of capacity each.
4.) So if you buy this, you need to think about whether you want to start buying 4-terabyte or 8-terabyte SSDs. If you opt for 4 in a RAID 5 array, you're looking at 4x(4-1) = 12 terabytes usable space. Opt for 8 and you get 24 terabytes, but have to pay more up front. Per a quick Search you could start out with 2 drives in a RAID 1, later add another and migrate to a RAID 5, so you don't have to buy 3 or 4 up front.

The 80Gps has more mass.
1M2 40G 5.2" x 2.8" x 0.9" @ 253 grams
1M2 80G 5.2" x 2.8" x 0.9" @ 280 grams
Replaced the drive in mine with a WD SN850x 8TB - and the results are slightly above those in the video. The thing flies!!
Presumably they identify as USB4 v2 in System Information.

macOS’ identification of these drives confuses me.View attachment 2582684Yes they do.
Even TB certified drives will identify as USB4 v2 in system profiler, such as the Envoy Ultra. It's just how Apple chooses to do it.macOS’ identification of these drives confuses me.
