    • SSK brand -- SSD drive
Capacity: 1TB
UPDATE - 10-6-2025: Super impressed with this external -- copies 50GB from another external -- the 1TB SSK drive connected to the C port, while the 500GB NVme connected to USB 3.0, the transfer of the 50 GB folder took just under 5 minutes. That may not be fast for some but for me and my past experience with transferring large file, this is fast. Figuring this speed in real time use, It should take approximately 50 minutes to transfer 500GB -- 10-03-2025 first post Loving this little guy -- fast enough, and by that I mean it is acceptable --- not slow, but not a rocket either. Anyone who had dealt with the over blown claims and actual use on you pc. At first blush I have to say, I love this 1 TB, actual -- 953GB -- as we all know, all of the drives, hard or flash, over rate the storage space you think you get to use. There always seems to be around 100 mb used on the drive that you cannot use. Kinda like car manufactures selling cars they say will get a certain mpg, a figure you, as owner, never seem to get. Anyway, this is a sweet little SSD drive -- SSK brand, has a pretty good reputation, from what I have seen on internet reviews. The price is outstanding. Being an SSD drive is a couple of steps above a standard Flash drive. I have a 500GB NVME drive I took out of a laptop and put in an enclosure, making it and external drive. It runs hot, makes for a good hand warming during cold times, but not so much in the summer. This SSK, almost 1TB, seems to run much cooler, and physically is less than half the size. The one thing I do not like is that you have to use a cable -- well, you don't have to, but this is what it comes with, a 10" cable to connect to pc. I have order something much shorter and a direct connect so no dangling wire. So far so good. I have tried it on a couple of different laptops and it works flawless. I might mention that the packaging is triple A, very nice high end-- too bad to, as it will go to the trash -- sad -- but the first sign of quality, both in and out of the box. This was truly a plug and use, and it seems to run cool -- it gets warm, but so far not HOT, unlike the NVME drive. Love it. I will repost if anything goes sideways. Time will tell. ... show more

    • Great value
Capacity: 512GB
I’m very happy with this drive. It’s fast, compact, and feels well built, making it easy to carry around without worrying about damage. File transfers are noticeably quicker compared to traditional external hard drives, which saves a lot of time when moving large files. It plugs in and works right away with no setup issues, and it stays cool and quiet even during longer use. The sleek design is a nice bonus, and the storage capacity is perfect for backups, schoolwork, or media on the go. Overall, it’s a reliable, high-performance external SSD that offers great value for the price. Highly recommended. ... show more

    • easy to install
Capacity: 128GB
My brand new computer didn't have anough memory. Our IT guy suggested that we get an SSD device and we found this one. It's nice and compact, very easy to install and easy to transfer the gazillion pictures that were taking up too much space. Now our computer works better. Thanks SSK!!

    • Works as Advertised (cable may be faulty though)
Capacity: 512GB
I got this external SSD for hooking up to a Raspberry Pi 5 as a media center. I was going to go with an external HDD but wasn't sure if the Pi could supply sufficient power, but anyways; Yeah the SSD works great, it was a lot smaller than expected but that's on me haha. I did have one issue with it though... I though it was DoA because it wouldn't show up on my PC, nor in the partition manager. Not even an indicator light was on. After a bit of troubleshooting I realized it was the USB cable it came with that was broken. It worked right away after using one of my own cables. Maybe I just had bad luck, but if yours doesn't work either, try swapping the cable. ... show more
