EL artículo es excelente, cumple con todas mis espectativas. Gracias.

Works as advised. Not quite the speeds listed but that could be more to do with my setup and devices.

My 2019 5K iMac had been crawling along on its original failing 2 TB Fusion Drive. Cold boot times were routinely 5–8 minutes, and even opening apps felt like 2010 all over again. I had heard success stories of opting for an external drive to replace the failing Fusion Drive and bought the ACASIS Thunderbolt 3 enclosure + Samsung 990 PRO 2 TB combo.Result:- Cold boot to login screen: 25 seconds- Fully usable desktop: 40 seconds- Parallels Desktop now runs Windows 11 + Debian Linux side-by-side with zero lag (impossible before)- Large file transfers are instant- Maintained 2 TB of storageInstall was straightforward: cloned my drive, set the external as startup disk, and it just worked. The built-in fan is whisper-quiet but keeps the 990 PRO cool even under heavy load. Build quality is excellent – solid aluminum, short Thunderbolt cable included, and the little fan toggle is a nice touch.If you have an older Intel iMac that’s dragging its feet, this might be the single best upgrade you can make in 2025. Zero regrets – my six-year-old machine feels brand new again.Highly recommended!

Purchased this to house a Samsung 990 PRO 2TB SSD attached to a Mac mini m4. Easy to set up and it works great. Connected to a TB4 port in the back of the Mac mini (using the cable that came with the enclosure), I find the read/write speed to be very fast. This allows me to run Lightroom and photoshop, as well as other large apps on the external drive and keep the small internal drive of a base Mac mini freed up. LR and PS open very quickly and run smoothly. I attached one of the heat strips (thicker one) that came with the enclosure to the SSD and I run the fan on the enclosure. The fan is very quiet. The enclosure sits on my desk, behind a monitor and I don't notice it running. Without the fan, the enclosure did get a bit warm (I wouldn't say hot). With the fan, it stays pretty cool and the SSD temperature seems to drop 10C with the fan running. I am very pleased with my purchase.

I put a Samsung 990P 2TB in my 401 Pro case. Everything was a breeze except that it took me a moment to read the instructions and put the little rubber grommet in to hold down the SSD drive; otherwise it wanted to angle up.Plugged it into my Mac, it said it was unreadable and offered to initialize it, which opened up Disk Utility. Not entirely obvious but it seems Erase is the command you choose to format a drive. That took less than a minute. After that MacOS volunteered to back my internal drive up to this via Time Machine, and I acquiesed quickly and set it to use no more than 1.25TB of the 2TB.I was pleased to see that the enclosure apparently has no less than 3 temperature sensors (again, this is the Pro version with fan, so I don't know about the normal version nor about previous Pro versions if any). They don't show up on most of my utilities, but they do show up on TG Pro.So far the drive has been running for an hour solid and the highest of the 3 cases temperatures (Top Case) is 44 C. The enclosure specs and the drive specs both say max 70 C, so I'm pretty happy with 44 C--in fact, the highest sensor on my internal drive is reading the same.I am wondering how long I can expect the drive to last. I won't be doing A/V work, but I will move my massive Photos library to the drive, in addition to Time Machine. I'm guessing maybe 5 years is a pretty safe bet? I expect SSD storage to drop further in price by then.BTW, I am assuming that if the enclosure dies I just move the SSD to a new enclosure. Of course, if the SSD dies, the data is gone, but that's why this drive is for backups, local copies, and other non-crucial things.
