40Gbps M.2 NVMe SSD Enclosure, with Cooling Fan, M.2 Enclosure for M1 M2 Pro/Max, Compatible with USB3.2/3.1/3.0/2.0, Support SSD 2280/2260/2242/2230 B+M M-Key

Very effective and high quality ssd enclosure. it is very well made, easy to set up with whatever SSD you have. It has a metal body and ventilation ports with the addition of a quiet switchable fan: so temperature control should not prove a problem. It is future proof in spec and although not cheap I feel offers very good long term use at a reasonable cost.

This is a great external drive housing for a Mac Mini. Its Thunderbolt 4 connector means that it performs really well. Not quite as fast as the internal SSD but pretty close. It comes with a Thunderbolt 4 cable which is well constructed. Fitting the SSD was simple and took a few seconds. The case is metal and solid - it will survive the rigours of travel. My only criticism is that the fan needs to be switched on or off using a button. I would much rather that the fan is triggered when the SSD temperature goes above a certain level. I found the fan to be a little noisy but it is not far from me and it may be less intrusive in other setups.

Excellent enclosure - easy assembly, speed is excellent - around 3100MB/2900MB R/W. Temperatures have been great even WITHOUT turning on the inbuilt fan (when mac is under GPU load running LLM related workload - see screenshot): SMART/Health Information (NVMe Log 0x02, NSID 0xffffffff) Critical Warning: 0x00 Temperature: 32 Celsius Available Spare: 100% Available Spare Threshold: 10% Percentage Used: 0% Data Units Read: 1,977,041 [1.01 TB] Data Units Written: 1,804,176 [923 GB] Host Read Commands: 20,136,510 Host Write Commands: 14,040,961 Controller Busy Time: 230 Power Cycles: 52 Power On Hours: 59 Unsafe Shutdowns: 4 Media and Data Integrity Errors: 0 Error Information Log Entries: 0 Warning Comp.

This is a fantastic item, it’s reasonably small in size and the build quality is superb, light alloy with a switchable cooling fan that is hardly audible, I fitted this with a 2TB Samsung NVME 990 pro drive, and attached this to my Mac mini m1 and set it up to be the boot drive, this runs perfectly. I am getting faster speeds from this drive than I am getting from my Mac M1’s built in ssd hard drive. File transfers are so fast. It has never overheated even under continuous loads. I will be purchasing a second one in the future and have no hesitation in recommending it.

Excellent quality and great speed. Speeds are as advertised but will vary depending on the SSD drive of course. Great build and quality. Well worth it

I’m getting good results with this and a 4TB Samsung 990 PRO (I got in a sale) on my M1 Mac mini. The results are 3100 MB/s for sequential reads on 1Gb files and 2800 MB/s for sequential writes when using the Samsung Magician benchmarks. I get roughly the same results with BkackMagic benchmarks. But, weirdly, on AmorphousDiskMark the sequential write is cut in half to 1500 MB/s. I can’t find any explanation for this online, so I can’t be certain that the Acasis enclosure is not to blame (I used the supplied thunderbolt cable and two other branded cables as well). I was happy enough with the BlackMaguc results to keep it. The switchable fan is good, and I’ve stopped noticing the gentle whirring (putting it under my desk helps). Enclosure temperatures are good considering the reputation fir the SSD to get very hot.

Great prodect

I needed an SSD for video editing (to save were and tear on my laptop's internal drive). I paired this with a WD 2TB NVMe SSD and it flies. It's plugged into a TB4 port on my Caldigit TS4 and, whilst not as fast (according to the Blackmagic speed tester) as my MacBook's internal SSD, it's running at full Thunderbolt 4 capacity. No more stuttering when editing video (something I was starting to get with my Samsung T7). This enclosure has the advantage of a switchable fan - not needed most of the time and I only click it on when transferring large files to it, and when rendering final video (as that seems to be when it gets hot) - the solid aluminium box is plenty of heat sink for more normal use.

Su acabado es excelente , todo en aluminio, como indica ,no necesita herramientas para la instalación de la memoria. Todo se hace de forma sencilla y funciona eficazmente. He comprado un cable Thunderbolt 5 para garantizar la estabilidad de la transferencia de datos, (pues había leído que en algunos circunstancias, el cable que viene no garantizaba estabilidad, pero no he llegado a probarlo) , de momento solo puedo hablar maravillas . Velocidades muy rápidas apenas genera ruido y de momento en mi experiencia no se calienta apenas , tiene un ventilador incorporado que puedes conectar o desconectar que genera un poquito de ruido, pero yo no he tenido que usarlo. De momento muy satisfecho con la compra. Lo estoy usando con una memoria de Samsung la 990 evo plus de 4TB

Enclosure decisamente riuscito per chi vuole sfruttare un SSD NVMe esterno senza i limiti tipici dei box USB più economici. Con host e cavo adeguati, la differenza rispetto a soluzioni standard si sente subito: trasferimenti molto rapidi, buona stabilità e soprattutto prestazioni che restano costanti anche sotto carico. Il punto forte, oltre alla compatibilità con Thunderbolt 4/3, è il raffreddamento attivo. La ventola integrata aiuta concretamente a contenere le temperature dell’SSD durante copie pesanti, montaggio video o utilizzi prolungati, riducendo il rischio di thermal throttling, che su molti enclosure passivi arriva abbastanza in fretta. Apprezzabile anche la compatibilità ampia: funziona bene sia in ambiente Mac con M1/M2 sia con host USB-C compatibili, fermo restando che le prestazioni finali dipendono sempre dalla catena completa (SSD installato + porta del computer + protocollo effettivamente supportato + cavo utilizzato). Questo va detto, perché i 40 Gbps sono il limite teorico dell’interfaccia, non una velocità reale sempre garantita in ogni scenario. Costruzione solida, montaggio semplice e formato adatto a più tagli di SSD. Nel complesso è una soluzione molto valida per chi cerca un box esterno NVMe davvero performante, non solo sulla scheda tecnica ma anche nell’uso reale

Utilisé avec mon MacBook Air M1 pour du montage video, je profite de débit beaucoup plus rapides qu’avec mon Samsung T7. (Pratiquement 3000 en lecture / écriture avec un M2 Samsung 990 Evo Plus de 2To). D’après ce que j’ai compris, ça pourrait être plus rapide, mais c’est dû au contrôleur de la puce M1. Cependant, c’est largement assez rapide pour travailler sur Final Cut avec de « gros rushs », sans ralentissement (ce qui arrivait de temps en temps avec le T7). Je n’ai pas du tout remarqué que le boîtier chauffait fort, à tel point que je ne sens pas l’utilité d’allumer le ventilateur. Ce dernier fait un petit peu de bruit, mais il suffit de l’éloigner avec le cable plutôt long (par exemple le placer derrière votre écran) et le bruit devient vraiment très faible. Pour moi qui déteste les bruits de soufflerie et qui aime travailler dans le silence total, ce n’est pas vraiment gênant (surtout quand on fait du montage video, puisqu’on va forcément entendre du son des rushs). C’est donc un bon produit, peut-être un peu cher quand même à l’heure où le Thunderbolt 5 arrive, mais ça reste quand même intéressant quand on voit le prix du stockage chez Apple ou chez des vendeurs de SSD externe qui propose du Thunderbolt…

Das ACASIS 40Gbps Thunderbolt NVMe-Gehäuse hat mich voll überzeugt. Ich nutze es für schnelle Datenübertragungen und Backups – und die Performance ist beeindruckend. Dank Thunderbolt 3 erreicht es nahezu die maximalen Geschwindigkeiten meiner NVMe SSD. Besonders praktisch: Der SSD-Wechsel geht in wenigen Sekunden, ganz ohne Werkzeug. Auch das Anschließen am MacBook war plug & play – sofort erkannt, keine Einrichtung nötig. Pro: • Sehr hohe Übertragungsgeschwindigkeit (echte 40 Gbps bei passender SSD und Anschluss) • Werkzeugloser SSD-Tausch • Hochwertiges Aluminiumgehäuse, gute Wärmeableitung • Kompatibel mit Mac & Windows Kontra: • Wird unter Dauerlast etwas warm, aber im Rahmen Fazit: Top-Gehäuse für alle, die maximale Geschwindigkeit und einfache Handhabung suchen. Ideal für schnelle Backups, Video-Editing oder als portabler Speicher

Carcasa de muy buena calidad, construida toda en aluminio y con acceso al SSd sin herramientas. Ventilador con sensor de temperatura muy silencioso. Montada con un SSD WD 770SN, que no es de los más rápidos, obtengo una velocidad de lectura y escritura de 2600mb/s en un Mac Bock Air M1. Muy buena opción para ampliar memoria o trabajar con archivos muy pesados a buena velocidad y con la temperatura controlada.
