Update:Added a real word 22+GB large file transfer screen shot. It is being transferred from NVME drive to the SSK that is formatted as NTFS USB 3.2 gen 1. It gets a solid 300+MB/s write speed the enter transfer after the small cache runs out. There is a couple of short dips in speed as I was doing things in the background while running the copy test. A real-world speed test. It's nice to see it really is as fast in real-world as it is with synthetic benchmarks. Not all USB flash drives sold can do this. Also note the random read/write speeds are a good deal faster than most USB flash drives! Last, this review shows that it is as fast regardless of if formatted FAT32, exFAT, or NTFS. A lot can do this speed but only format as exFAT or FAT32. Format it the other way and the speeds drop a bunch. Again, a nice surprise as not all the USB drives, I have tested could do that!Original Review:SSK 128GB Dual USB is as fast as stated in product description, all the while having a really reasonable price to match! You may notice my benchmarks are about 100 to 130MB/s slower than the drive's rated speed of "Up to 550MB/s". This is due to my PC is only USB C 3.2 Gen1, not Gen2 the drive speed is rated. If my PC had the Gen2 type CF then it would ease to match the stated speed advertised. I also test the drive formatted FAT32, and exFAT with little difference. It was easily within margin of error. The only thing that seems to really cause this drive to slow down by a very large margin is USB A by a factor of 10x. Also, make sure if you a testing the speed of the drive to change it in device manager to faster performance, not fast withdraw. See my screen shot to see the settings.Summary, an easy 5 stars for a fast reasonably price USB C drive which backwards compatibility of USB A.

Lightning Fast!!!This SSD Jump Drive is solid, and love the dual ends USB-A and USB-C- Drive Format Supports: exFAT or NTSC.However, I bought it to play MP3 Music in my new 2025 Subaru.My Subaru : (- Only Recognizes up to 128 GB Drives- Must be FAT32The SSK 128GB Flash Drive:- Is made of metal, so very durable.- It is nicely boxed, (no blister=anoying plastic pack to cut open)- It also comes with a closeable slip-cover with key-ring.

I love the sturdy feeling of this flash drive. the dual side is great if you use Macbook and PC so I can use either USB C or the USB.

This is hands-down the fastest drive I own. I'll show you the actual winsat results below. Also, the construction is durable metal, so it's perfect as a keychain drive. I would HIGHLY recommend this one.Test for Type-C port:PS C:\WINDOWS\system32> winsat disk -drive EWindows System Assessment Tool> Running: Feature Enumeration ''> Run Time 00:00:00.00> Running: Storage Assessment '-drive E -ran -read'> Run Time 00:00:00.16> Running: Storage Assessment '-drive E -seq -read'> Run Time 00:00:01.78> Running: Storage Assessment '-drive E -seq -write'> Run Time 00:00:02.11> Running: Storage Assessment '-drive E -flush -seq'> Run Time 00:00:00.70> Running: Storage Assessment '-drive E -flush -ran'> Run Time 00:00:00.72> Dshow Video Encode Time 0.00000 s> Dshow Video Decode Time 0.00000 s> Media Foundation Decode Time 0.00000 s> Disk Random 16.0 Read 430.99 MB/s 8.2> Disk Sequential 64.0 Read 514.64 MB/s 8.1> Disk Sequential 64.0 Write 437.66 MB/s 8.0> Average Read Time with Sequential Writes 0.431 ms 8.1> Latency: 95th Percentile 0.675 ms 8.6> Latency: Maximum 4.094 ms 8.6> Average Read Time with Random Writes 0.410 ms 8.7Test for a Type-A port:PS C:\WINDOWS\system32> winsat disk -drive EWindows System Assessment Tool> Running: Feature Enumeration ''> Run Time 00:00:00.00> Running: Storage Assessment '-drive E -ran -read'> Run Time 00:00:00.16> Running: Storage Assessment '-drive E -seq -read'> Run Time 00:00:01.42> Running: Storage Assessment '-drive E -seq -write'> Run Time 00:00:02.23> Running: Storage Assessment '-drive E -flush -seq'> Run Time 00:00:00.86> Running: Storage Assessment '-drive E -flush -ran'> Run Time 00:00:00.89> Dshow Video Encode Time 0.00000 s> Dshow Video Decode Time 0.00000 s> Media Foundation Decode Time 0.00000 s> Disk Random 16.0 Read 292.54 MB/s 8.1> Disk Sequential 64.0 Read 399.62 MB/s 8.0> Disk Sequential 64.0 Write 333.65 MB/s 7.8> Average Read Time with Sequential Writes 0.502 ms 7.9> Latency: 95th Percentile 0.770 ms 8.5> Latency: Maximum 4.049 ms 8.6> Average Read Time with Random Writes 0.519 ms 8.7> Total Run Time 00:00:05.63

I am an older lady who is not computer savvy so brought it to my son-in-law to show me what I need to do to download all of my photos to one spot (the memory stick). The size, the carrying case, and hopefully ease of use when I learm is what I need to do to get photos transferred and safe, Iwill eliminate a lot of my photos. Thank you, Sharon

I absolutely love this drive, I purchased 2 of them. I keep one in my pocket at all times when I’m at work on show sites. Very versatile.

Coolest USB drive ever. With a mix of computers, printers, and other stuff it is nice having this simple double end drive to transfer stuff. Mainly used for files I want to move from a scan off by All-in-One over to a computer to email a physical document I need to transmit. Works like a charm.

Value for money:great product for the money.Storage capacity:512 gb good for most storage optionsEase of use:all formatted and ready to go
