Solid feel, speedy transfers!
I’ve always owned SanDisk or Patriot flash drives, and hesitated on purchasing this one—even at a great Prime Day price. I didn’t fully understand about it being a SSD (not a typical) flash drive, and the mentioned (very fast) speed of transfers. Plus, there weren’t many reviews. But I bought it, came yesterday, and WOW!First, this thing feels extremely ‘quality-made’. It’s metal, and does get warm, but not ‘ouch’ hot like my SanDisk, which eventually cooked itself into oblivion.Second, this is the fastest drive I’ve ever owned. I didn’t test it, but I transferred 30 years of teacher files (@700 gb) from my desktop in a short evening. I am seriously impressed!Finally, this thing just feels right. It’s a bit heavy, and it’s not small like my dearly departed SanDisk, but its sturdiness lends confidence that it is a survivor. It has both USB C & A plugs, and the latter has a cap. Not to worry, it fits tightly.The final touch is a nice case to attach to a key ring.Am I satisfied? You bet. As to longevity, I don’t know. My Patriots had the best warranty on the planet, and if I hadn’t lost them, I wouldn’t have needed this one. But this is one fine, fast, quality, drive. My only regret was not getting the two terabyte model!
Great drive
very fast. Need to turn on write caching for full speed but once you do it sustains about 800MB/s speeds. Love the feel and weight of it and the carry pouch is perfect for EDC on keychain.
Very very fast. Very hot as well.
Firstly, this flash drive is really fast. I was getting advertised speeds on my MacBook Pro. Copying large images, videos, documents, etc, the drive performed flawlessly. The metal housing makes it easy to stick in my purse. It’s super small and light weight.However, it got really hot. It was to the point that I couldn’t really touch it because the casing is metal so like picking up a hot pan or something. If the heat level was less, I would give it a 5 star and automatic recommendation to everyone. But as it stands, 4/5.
Eventually Not Responding
At first the disk was great. However, after a while the disk started to transfer slowly. After a week or so of this, now it will not access files/folders without getting a “Not Responding” message for over 5 minutes. Eventually, the disk will either respond (but only for a minute or so) or it will disappear from the system altogether. Running Windows 10. I have tried reformatting the disk (lost some data) and I get the same thing.I have contacted ssk customer support twice regarding warranty on this item and another and have not heard back from them. Very poor customer service.I would avoid this brand.
Only transferred at about 36MB/s. I tried reformatting in different formats (NTFS/exfat) and sector sizes. My other USB transfers at over 100MB/s. I sent this one back for refund. Refund went through quickly.
Se percibe de material pesado y duradero, con la entrada tipoC la velocidad de descarga fue rápida(55gigas los descargo en 5 min, con la entrada tipoA el mismo volumen lo recibió en 15 min aprox) me parece muy práctica y funcional. Aplica para la unidad de 1T y para la de 512 Gigas.
