Re: First experience with NVMe M.2 in enclosure - bad.
I got the OWC Envoy express today, and had exactly the same experience as with the other enclosure I tried. Everything works fine copying, reading, speed testing, until I get to about 25-30% occupied space; the disk and its volumes ejects, gives the eject error alert, and is difficult to reformat because it will self-eject very quickly after showing up in Finder.
So, I assume it's my Kingston 2TB NVMe M2 SSD that is at fault. I'll try to get them to replace it or give me my money back. The OWC enclosure was significantly cooler BTW, but also a little bit slower. 1300/1000MB/s read/write speed, vs 1500/1300 on the other one I tried.

Re: First experience with NVMe M.2 in enclosure - bad.
I’ve been using this for several weeks now…
Case, active cooling Thumderbolt 3 https://fledging.tech/products/shell-thunder SK hynix Platinum P41 https://www.tomshardware.com/reviews...p41-ssd-review It Blackmagic speed tests consistently at 2500 MBps or so consistently. In use it’s plenty fast. Big improvement over my EVO850 in an OWC barebones USB 3 case.

Re: First experience with NVMe M.2 in enclosure - bad.
The case is working well. I haven’t heard any discernible noise from it and it runs at room temp. The bottom of the MBP is much warmer though if I’m working in my place I bought a Svault cooling block (the block is a bit spendy but works well and looks good). The primary machine it’s used on is an M1 Pro Macbook Pro. I formatted it APFS so I’m not able to take it a Windows box directly unless it has Paragon or Mac Drive (and Thunderbolt).

Re: First experience with NVMe M.2 in enclosure - bad.
There’s a 95% chance I’ll make the switch from PC to MAC Studio max. Will have to have the 3-slot Sonnet case for my UAD Octo card, and I figured on 2 Samsung m.2 drives for my sessions.
Are these cards okay? SYBA SI-PEX40110 M.2 M-Key NVMe PCI-e to PCI-e x4 Converter Card |

Re: First experience with NVMe M.2 in enclosure - bad.
+1 for the OWC4M2 with 4x 2Gb Samsung 980 Pro’s set to RAID 0 which enables you to use all 16 lanes of Thunderbolt thru for transfers of ~2500 m/bits.
I bought four of them.

2500 Mbit/s is just what you get sucking over those 4 x PCIe3 lanes with RAID. If you had 16 lanes of PCIe3 access to those M.2 cards you would have many several times this amount of bandwidth. And when you don't use RAID, each drive gets 1 x PCIe 3 lane of throughput vs. the 4 x PCIe 3 lane it would get in a better implemented enclosure that uses a PCIe switch. And real world storage workloads may not be as good as RAID benchmarks imply. Still compared to a slow old rusty spinner these systems are fast. |

Ah, my mistake.
Their website seems to say it’s x16? https://eshop.macsales.com/shop/ssd/owc-accelsior-4m2

More Lanes = Faster Throughput Accelsior 4M2 was designed with a PCIe switch to let your computer address each of the M.2 NVMe drives at full x4 PCIe speeds instead of hard-limiting each drive to x2 PCIe speeds. When running in JBOD, where all four drives are typically not accessed at the same time, each drive has the unlocked capability to run at full speed. ... so I think this is a victim of OWC's naming conventions, where the 'Accelsior 4M2' card also requires a PCIe chassis/enclosure, Darryl was referring to their all-in-one '4M2' device, which lacks a PCIe switch, here (I stand to be corrected) ... https://eshop.macsales.com/item/OWC/TB3EX4M2/ |
