The Mac Mini with an internal HDD was getting slow.

- Reviewed in the United Kingdom on 27 December 2019Style Name: X8 Portable SSD (Up to 1050 MB/s)Capacity: 500 GBVerified PurchaseStraight out of the box a Blackmagic speed test gives read and write speeds of around 900mbs, perfectly acceptable if slower than advertised, I copied 150gb of photos which set off at speed but after 10 mins the drive got very hot and slowed down incredibly, that I canceled it. I then attached my 1tb LaCie ssd (£140 on Amazon) and copied the photos to each of the drives at the same time, The LaCie copied in around 8 mins, this Crucial drive was still copying after 25 mins!!!!
Very disappointed in it.
It works and is fine for copying in small doses, but for proper jobs, buy the LaCie drive.

5.0 out of 5 stars Soporte de Sistema Operativo de iMac
Style Name: X8 Portable SSD (Up to 1050 MB/s)Capacity: 500 GBVerified PurchaseHola. Pues compré este disco para instalar en él el sistema operativo de un iMac de 21" de 2015 que iba lentísimo. Fue formatear el Crucial como disco de arranque y elegir en el iMac que arrancara desde él y... ¡ordenador nuevo! Va mucho más rápido que recién comprado. Es una maravilla. El caso es que en las pruebas que le hice no pasa de unos 400Mb de lectura/escritura para traspasar ficheros, pero en la realidad va rapidísimo y con mucha estabilidad.
Si tienes un ordenador viejo al que no le puedes cambiar el disco interno de arranque, te lo recomiendo sin ninguna duda. Por cierto, después de las diversas actualizaciones del SO del Mac, sigue funcionando estupendamente con Big Sur. Pues eso un 10 de 10.

5.0 out of 5 stars C'est l'affaire du moment.
Style Name: X8 Portable SSD (Up to 1050 MB/s)Capacity: 500 GBVerified PurchaseUpdate : 5 étoiles compte tenu du rapport qualité/prix.
Modèle 500 Go (115€) Installé sur un Macmini 2018 comme disque de travail pour mes RAW.
Quelle rapidité (bien supérieure à mon Samsung T5), même si on n’atteint pas les 1050 Mo/s annoncés.
Certes il n'est pas TB3, dont l'intérêt principal est la capacité de chainage.
Quand à la vitesse offerte par le TB3, il faut vraiment en avoir besoin (pour la vidéo ?).
Pour la gestion du trim impossible pour le moment en usb sous OSX, je n'ai jamais subis de ralentissement avec mes vieux ssd en usb, donc je considère que ce n'est pas un point bloquant.
Au pire on passe le ssd sous W10 qui le gère.
Le X8 bénéficie d’une très belle construction en métal avec un cable un peu court (voir si ce n'est pas trop court derrière un iMac).
Le seul point négatif c'est la chaleur dégagée (surtout lorsqu'il est sollicité).
Mais comme ce problème est inhérent à ce type de ssd, et pire pour les ssd en TB3 (Samsung X5 et LaCie Bolt 3), je lui laisse 5 étoiles.
Selon moi, le X8 c’est le bon plan du moment, surtout en 1 To (moins cher qu’un X5 500 Go).

5.0 out of 5 stars It is very portable, solidly built, and uber fast until the SLC cache is used up.
Style Name: X8 Portable SSD (Up to 1050 MB/s)Capacity: 500 GBVerified PurchaseIt is one of the fastest USB 3.2 Gen 2 external SSDs out there. It is small but solidly built like a paper weight. It works just like any other external SSDs/hard drives. The writing speed can be as fast as 800ish MB/s until it hits the SLC cache ceiling. It will then drop to hard drive speed. It will then pick up and drop again The phenomenon is especially obvious when larges files are being transferred. It is normal behavior for all external SSDs. Some profiles give you the faster overall speed than others.
One thing to add. The X8 only comes with a USB C to USB C cable with a USB A adapter. The adapter somehow reduces the speed to USB 2.0 territory. I test it out with another USB C to USB A cable and it works at USB 3.2 Gen 1 (or USB 3.0 if you wish) speed
