256GB Ultra Dual Drive Luxe USB Type-C - Up to 400MB/s - SDDDC4-256G-GAM46

Works good but gets hot. I wrote the same thing on a different one I bought and I still don't know if it's good or not but if I'm doing a real big file transfer and speed slows down I take some canned air upside down and give it a couple squirts of CO2 and the speed picks back up. I've had it for over a year and moved a lot of files and it still works.

seems pretty great so far - i did a speed test, included are the results. this speed test is on a 5Gbps USB3.1 Gen1 Type-A port on a Z-370 motherboard with an 8700K and 64GB DDR4 RAM (in case anyone was wondering) I realise the speeds will be lower in real workloads, and will as always, gradually go down over time. But, out the gate sequential speeds are faster than advertised, which is always great.

Very good & very fast. Runs hot

I bought this to carry on my key ring so that I could transfer demos and clips between my phone and my laptop on the go. I like this drive, but there's a couple things you should know. Build Quality ✅ - The drive is built well and very minimalistic. USB-A side is made of metal and the rotation between the two ports has a satisfying click. No sign of weak points, no complaints here. Speed ☑️ - Speed is relative, but it's plenty for me. USB-A side scored 382mb/s read speed and 152mb/s write, while the USB-C side scored surprisingly lower at 358mb/s read and 136mb/s write. The test was done on a TB4 laptop so not sure what happened here. It's possible the drive is optimized for USB A. Regardless, these speeds are good for me, but could be a deal-breaker to some. Thermals 📛 - The reviews scattered here are true. This drive got pretty hot after only one test and I'm a little worried about long-term reliability when it's cooking like this. To it's credit, running a test in its hot-state only dropped the speed by ~3mb/s. Luckily this drive cools pretty quickly as well. Size and features ✅ - Coming in at around 4.5cm, this drive is small. Not tiny, but small. The key ring addition was my main reason for purchasing and it seems nice. I do wish it had a quick-detach ability but I knew it didn't have that going into this so I can't dock any points. Overall not bad. Value ✅ - $25 is hard to beat for a 256GB flash drive from a reputable brand. Especially when you consider it's only $7 more than the 128GB variant. Add in the dual-ports, adequate speed, key ring attachment and all metal body, I think it's a pretty good value for people looking for something with these features, but if you don't need them, you may find better value elsewhere. Conclusion - This is a good quality drive with good speeds and a tendency to get hot. I won't be returning it but with that being said I will be watching it for any issues overheating.

Excellent usb drive. Very fast read/write speeds. Almost ssd level. And construction is high quality metal. Would recommend fully. Although it tends to run hot, like all metal usb flash drives.

I purchased this because of the size and space, I have a few 512 mb sd cards and usb thumb drives amongst others, I figured ok 1 tb would be a lot better , I was wrong,at least with this one , at first it looks nice , solid, metal makes you feel like it was worth it , then you use it, like I read other reviews ,first my computer crashed, ok thought nothing of it , it’s an asus gaming laptop , 3 month old, latest Ryzen processor all the best I could buy at the time , cost 3400. Should run anything I throw at it, well except this drive. Rebooted it worked shows the storage looked good, I wrote a couple files to it nice and quick. So I reformatted it , fat32 is what I needed , no problem took a min. Then I have to transfer my data, I do a lot of computer modding and video game modding , so loading 700gb it said 4 hrs , ok acceptable 7 hrs later says 3 hrs left and the gage was barely moving , I was like ok let me stop and start again from this point, well hot isn’t the word, this thing gets so hot I couldn’t hold it . I don’t know if it overheats and then slows down or if it isn’t great and screws up then over heats , point is for my use it does t work , I can’t transfer large files to it , I gets scary hot like it may cause damage to my laptop , and I also have to mention I tried this with the usb 3.2 ports and the usb c ports. Both caused extreme over heating, and then at that point you have to wait an hr or so before you can even delete anything . I am returning it and hoping to get my money back, I will look for some other small storage . Like I said I don’t know if it’s def. If I was just asking to much of it , maybe if you gave small files and just access it randomly it will be fine . But for me it’s going back.

I really like this drive it's reliable and hefty and solid--but it gets REALLY hot! I transferred 4-5k photos from an old phone to the drive and by the end i could only touch the drive for a second or two it was so hot, without it feeling like an iron. And if I leave it plugged into my PC consistently, it just gets really hot to the touch. I have the plastic variation of this drive and it is much flimsier technically but does not get even close to as hot. The metal body of the drive is basically a big heat sink! So, buyer beware!

This dual drive is incredibly useful! The all-metal design feels premium and durable. I love how easily I can move files between my iPhone 17 Pro Max and my laptop using the USB-C and USB-A connectors. It’s fast, compact, and very reliable for extra storage. A must-have for anyone on the go!

Very useful normal USB type A and type C. Very fast write speed.

Utmärkt !

çok kaliteli ve şık bir ürün

The write speed isn't above 100mbs/sec while the read speed is good around 360mbs/sec.

Brilliant small usb for my PC & iPad. Good quality
