## Description

Express 1M2 - 1TB Ultra-fast, compatible, and reliable portable USB4 NVMe SSD. Build your own or choose ready-to-run solutions.

Review: Speed, Heat and Upgradability not as good as expected - There are multiple versions of this device with 1TB, 2TB, and 4TB SSDs pre-installed or you can buy a version which is an empty enclosure in which to put your own SSD. I purchased the 1TB version. This device is advertised as delivering 3000MB/s for both reads and writes when connected to an M1 (or later) iMac. Having tested the device with my own M1 iMac, I can confirm that it does achieve 3000MB/s reads, but it would only achieve slightly less than 1000Mbps write speed (see screenshot) with my iMac. If you aren't worried about the speed of data transfer, there are much much cheaper SSD enclosures available (e.g. Sabrent do a metal USB-C SSD enclosure which I bought on desertcart which is much smaller, runs much cooler and only costs about £10, but then it only delivers slightly less than 1000Mbps reads and writes). As I wasn't getting the write performance I was expecting from this OWC Express 1M2, I decided to return it. To be fair, I have seen other reviews which show this device achieving 3000 MB/s writes so perhaps I was unlucky or perhaps it is just an issue with M1 iMac compatibility. A couple of other points to note: 1. The case of this device does get very hot when in use. 2. The versions of this device supplied with an SSD pre-installed do not appear to be upgradeable as the case appears to be sealed with the SSD already inside. If you want to buy an OWC Express 1M2, you may be better off buying the version which is an enclosure only and putting your own SSD in it. That way you can always change the SSD if you want one with greater capacity later or you can replace the SSD if it fails without having to junk the enclosure as well. In summary, this isn't a bad device. If you are primarily interested in read speed, then this device is extremely fast. If however, like me, you have an M1 iMac and you want something that has a fast write speed as well, based on my experience of it, you may be better looking somewhere else.

### ⭐⭐⭐⭐⭐ Top Performance ideal für schnelle Datenübertragung
*by L***0 on 18 November 2025*

Das externe SSD-Laufwerk von OWC mit Aluminium-Kühlkörpergehäuse überzeugt auf ganzer Linie. Dank NVMe-Technologie sind die Übertragungsraten extrem schnell, ideal für große Dateien oder professionelle Anwendungen. Dabei bleibt das Gehäuse durch die integrierte Kühlung angenehm kühl selbst bei längeren Transfers. In Kombination mit der SAMSUNG 990 PRO (4 TB) als internes M.2-SSD erhält man maximale Leistung. Die SSD arbeitet zuverlässig, ist sehr schnell beim Lesen und Schreiben und eignet sich perfekt für Video-Editing, Gaming oder anspruchsvolle Office-Anwendungen. Kann ich absolut empfehlen hochwertige Verarbeitung, starke Performance und ideal für alle, die Wert auf Geschwindigkeit und Stabilität legen!
