SSK 512GB SSD External Hard Drive, Portable SSD Up to 550MB/s Fast Solid State Drives External, USB 3.2 Gen2 for iPhone 15/16 Pro, Win, Mac, Android with LED Light, Trim, Smart Supported
Why the Full Capacity is Not 512GB For a New Drive?
Display capacity of 512GB SSD often appears as around 465GB on Windows. MacOS typically shows full 512GB. This display capacity reduction is from algorithms differences in which 1GB is interpreted as 1024MB on Windows and 1000MB on SSDs
Why I can’t Reach 500MB/s
The Crystaldiskmark testing speed for 6Gbps is expected to reach 500+MB/s. You can use CDM testing tools to verify this. In daily use, actual transfer speed depends on factors such as interface, protocols, cables, computer performance and files
Why Runs Hot When Using?
Heat generation is a natural occurrence in high-performance SSDs during intensive read/write tasks. This phenomenon is exacerbated during warmer seasons, much like how smartphones tend to heat up more in summer due to higher ambient temperatures.
Data Safety Reminder
To prevent data loss, please perform safe eject operation on your computer before unplugging the SSD and Wait until you hear the prompt before removing the device. Do not unplug the SSD during a file transfer task. Unplug it when transfer finishes.

SSK brand — SSD drive
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 postLoving 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.
Blazing Fast and Ultra Reliable!
The SSK 1TB Portable SSD is an incredible little powerhouse! Transfer speeds are lightning-fast—up to 550MB/s—and it works flawlessly with my iPhone 15 Pro, laptop, and Android devices. The sleek design with an LED indicator is both stylish and practical, and it stays cool even during large file transfers. Super compact, plug-and-play, and impressively durable—this SSD is perfect for anyone who needs speed, portability, and reliability on the go. Highly recommended!
Works great with my Osee Duet 8 ISO video switcher
The hard drive comes with a USB-C to USBC with an adapter converting to a USB type A. Very convenient size and weight. The drive is formatted in ExFat for compatibility with either Mac or PC. Easy plug and play operation. Metal case is durable.I use this for my streaming switcher which can save the videos. The read and write speed is adequate for recording eight individual video files in 1080P30.So far highly recommended for the performance and convenience. The drive has wide compatibility with many different operating systems.
Great quality build and works perfectly.
This is a very nice drive. Transfer speeds are quite adequate for my use. I use it to back up data from my desktop to take with me when I travel with my laptop. It does not seem to overheat. It was instantly recognized by both PCs. The size is perfect for tossing into my laptop case, and the price was great as well.
Perfect! Small and portable with the connecting cable.
Just what I needed and it works well. I will be ordering another one with more terabytes. Even came with a connecting cable
Good for saving computer space
I bought this so I can transfer the photos that are taking up space on my computer and phone to something else. It has worked very well and does not generate heat if plugged in for a long time. It is a very good size and seems to be pretty durable (I have not dropped it yet luckily) but I do recommend this item
Great product
The SSK 256GB SSD External Hard Drive was exactly what I needed to convert my files to a new laptop. It comes with all required connections. It was very fast in saving and transferring my files. It was very easy to set up.
