ACASIS 40Gbps M.2 NVMe SSD Enclosure with Cooling Fan Aluminum

I inserted a 4TB Crucial P3 Plus SSD into this and it was fairly simple to set up. It is very solidly build and has a premium feeling weight to it.The included fan can be useful for large transfers and it is very quiet, barely audible more than 2 meters away. The speeds are great too, often time averaging around 2GB per second. One thing to note is that this enclosure is more aimed at a static setup where you don't want to be swapping drives too often as it only includes two thermal pads which are needed for optimal performance but tricky to take off once installed.Overall, I recommend it and am happy with the purchase.

Needed some extra hard drive space without paying the Apple Tax on SSD so after researching wnet for this along with a 4TB Crucial P3 stick of SSD. I'm getting about 1400MB/s write and 2100MB/s read, and I was hoping for more in the region of just over 2000MB/s write, consdering the set up and via Thunderbolt 4. However, it may well be due to it being plugged into a Caldigit TS4 dock and also having a Thunderbolt 3 monitor attached as well as numorous other hardware attached to it, which is bound to reduce the bandwith, but that still appears to be slow. Strangely when I look at the system report, it is connecting at Thunderbolt 3 speeds. I am going to change things around to see if I can improve those speeds by plugging direct into the MacBook, which I have tried before, but still not getting the speeds I expected. As for putting it together, that was a breeze. From unboxing to up and running was 5 - 10 minutes max and I have had no issues withoverheating, with the fan being on most of the time, you dont really notice that much noise. It was stilll a cost effective way to add SSD to the Mac and in farness, even the speeds I am geting now is fine for what I am using it for, mainly for FCP and theres been no issues yet, but be good to improve them. Price for the enclosure was also good, on offer at the time, which often happens, look for those vouchers and the build is good, nice and sturdy, though it can possibly be a bit to eay for the top to become loose, but I dont plan on using it as a portable drive but more of a permenant fixture with the dock. I'm 75% happy with it, though if I was building anoter one, which i probably will, I'd probably try a different brand just for comparision of speed.

Excellent enclosure - easy assembly, speed is excellent - around 3100MB/2900MB R/W.

Fairly easy to setup. The thermal pads supplied are very thin and not suitable for a non-heatsinked Samsung 990 drive. 2x seperately purchased 1.5mm thick thermal pads, doubled up to 3mm, were required instead. This allows contact with the metal enclosure, but still allows the case to close securely. You may require different thicknesses depending on the drive you install.Transfer speeds are excellent and haven't had any issues so far with the two I purchased. Allows me to actively edit and playback 6K ProRes footage on my Macbook Pro with no problems at all.Worth getting the fan version IMO - the enclosure will get hot when you're actively working with it or doing lots of data transfer. It's about the same volume and pitch as a generic laptop fan on medium speed - not too intrusive. Shame you can't tweak the fan speed slightly, as the default speed keeps it plenty cold enough. Maybe there's a way of modding it?

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.

I like the compatibility, and the thermal with the fan and the thermal pad. The fan is silent and I think it starts/stops as it needs (I have other enclosures as the UGreen and the difference in sound and start/stop is noticeable by far). On the other hand it is really expensive (120Gbp when I bough it) for a REAL TB3 intel chipset (really stable, I have it 24x7 connected without issues) with a top speed of max 3GB/s even sold as 40Gbps (due TB3 specifications!)

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.

What a brilliant little device this is. So easy to use, and unlike my previous enclosure I tried, it just gets warm.Truly ‘tool free’ to put your NVMe chip in, use the rubber stopper and apply the thermal tape. Clip on the cover and you are good to go.There is a push button switch that turns the fan on and off. When the fan is running it’s very quiet, and very efficient at cooling. I leave the fan off and it is just warm. Perhaps under heavy data use the fan would be required.If I had to complain about one thing, the fan could be temperature controlled?Fully recommend this enclosure.I used a Samsung 990 Pro 2TB NVMe chip.

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

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…

Ich habe eine schnelle und zuverlässige externe Speicherlösung gesucht, um meinen Mac Mini mit zusätzlichem Festplattenspeicher zu erweitern, da die interne 512-GB-SSD für meine RAW-Bilder in Lightroom einfach zu klein ist.Zunächst hatte ich mich für ein anderes, sehr bekanntes Gehäuse entschieden, aber leider funktionierte es mit meiner SSD nicht wie erwartet. Meine Samsung SSD wurde nicht als Samsung-Laufwerk erkannt, die eigene Samsung-Software fand die SSD nicht, und die Übertragungsgeschwindigkeit lag konstant bei nur etwa 950 MB/s , weit unter den Erwartungen. Das war ziemlich enttäuschend.Daraufhin habe ich das Acasis 405Pro M1 bestellt und meine Samsung 990 Pro eingesetzt. Das Ergebnis: sofort Übertragungsraten von über 2800 MB/s – genau so, wie es sein sollte. Beim Arbeiten mit Lightroom bleibt das Gehäuse maximal handwarm. Bei größeren Datenübertragungen wird es zwar wärmer, aber nicht heiß und das alles, ohne dass der Lüfter laufen muss. Besonders praktisch finde ich, dass der Lüfter manuell ein- und ausgeschaltet werden kann. Neben einem lautlosen Mac Mini wäre ein dauerhaft laufender Lüfter störend. Nur wenn ich viele große Dateien übertrage und das Gehäuse spürbar wärmer wird, schalte ich den Lüfter für 2–3 Minuten ein. Danach kühlt das Gehäuse schnell wieder ab.Einen kleinen Punkt habe ich dennoch angepasst: Das mitgelieferte Wärmepad habe ich ersetzt. Im Lieferumfang sind zwei Pads enthalten (ein dünnes und ein dickeres). Ob diese für die Samsung 990 Pro ausreichen, kann ich nicht sicher sagen. Anfänglich hatte ich beide übereinandergelegt, habe mich dann aber für ein GELID-Wärmepad mit 2 mm Dicke entschieden, das vermutlich eine bessere Wärmeableitung an das Gehäuse bietet.Insgesamt bin ich mit dem Acasis 405Pro M1 in Kombination mit meiner SSD sehr zufrieden. Das Gehäuse arbeitet lautlos – außer, wenn ich den Lüfter bewusst zuschalte. Dieser ist zwar leise, aber auf einem sonst ruhigen Schreibtisch durchaus hörbar, allerdings immer noch leiser als meine externen 3,5"-Festplatten.Von mir gibt es dafür 5 von 5 Sternen. Zwar ist das Gehäuse nicht gerade günstig, aber vergleichbare Modelle liegen preislich in einem ähnlichen Bereich. Wer eine leistungsstarke und leise externe SSD-Lösung sucht, ist hier meiner Meinung nach sehr gut beraten.

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.
