Oyen Digital U34 Bolt 2TB (USB4 40Gbps) NVMe Thunderbolt 4 (USB-C) Portable SSD, Up to 2800MB/s

I haven't had a problem (touch wood) with the two 4TB I purchased late 2024. Ridiculously fast, and they don't get hot. My opinion - and I have at least 20 SSDs from SanDisk to Samsung in all sizes and speeds. All have been excellent, but none can beat the speed of this drive. It's like having an extra disk in your Mac Studio, Mac mini, or Desktop. Stunning performance. Compact with an excellent rubber buffer, you won't be disappointed. Okay, my desk needs a clean-up already. :)

Woah this thing is fast! Tested on my MBP M2 Max and a Mac Studio M1 using 5GB (large file) setting using blackmagic's testing tool (avail. on the app store). The picture is the MBP but about same results for the Studio (though note that you have to use the ports at the back; the ones at the front only allow transfer up to a little over 300Mbps) Cable is provided (that's important). The drive comes formatted as HFS+. First screenshot is with the original HFS+ partition, second is after re-formating as APFS. HFS is for compatibility with older MacOS pre-Sierra and is less optimal for SSDs, especially for smaller files. Also while APFS is not PC-compatible, neither is HFS so there is little to gain for keeping it as HFS for the regular Mac user. Other big plus: the drive is small (basically the part not covered by the rubber thing in the middle is slightly smaller than a credit card in surface, so the whole thing is just a nudge wider than a credit card) and relatively thin. Fits in a jeans pocket like a pretty full wallet would (not that I would carry it like that, but it means it fits easily in a front pocket of a backpack) NOTE: External SSDs have a bad tendency of failing (just bought this after my Kingston failed within 6mo - granted manufacturer warranty is good for 3 years for these type of devices) so will come back in ~6mo to confirm everything is fine.

Much faster than usb 3. I ran a full backup with an external usb 3 hard drive that took over 30 minutes. I ran the same backup with this drive in just over 6 minutes. Be careful to use the proper cable length. The 10ft Thunderbolt 4 cable that I bought did not work with this drive. The supplied 1.5ft cable works great.

I bought a few of these, They are super fast , I was impressed. However keep in mind Black Friday is coming up and these drives were always listed at $399.00 but I see now just a few weeks before back Friday is here and I hope they don’t say ok it's On sale for Black Friday and take it back down to the regular price instead of discounting it? Even though it is worth the $400 going above that is not too realistic. They should put ti on sale around $350 or less instead of pushing the price up to $499.00 then dropping it to $399 or more. I hope they don't do that. but we will see shortly Black Friday is coming in just over a week. Be aware.

This Bolt HD works well with my PC Thunderbolt 4. As far as I can tell, it comes close to living up to the speeds quoted. I like the sturdy, shock absorbing, case! The phone support is the best of any company that I have called! A knowledgeable person answered - right away. Had a very friendly and informative conversation. That is nearly unheard of these days! A very welcomed experience.

Lack of marking indicating that the unit is 4TB ssd One year after purchase before a vacation trip, I grabbed this unit thinking it is a power bank and finding out too late later that it is an ssd. Otherwise the unit functions as advertised.

Maybe the one I bought was defective — I’m not sure. It worked great for about three months, but now it causes my computer to lock up. I’ve tried it on multiple computers, and each one freezes until I unplug the drive. Its only purpose was to store music samples and instrument libraries. It sits on my desk plugged in all the time and never gets moved around. One day it just stopped working.

Lightening fast with MacBook Pro 2.7-3.0 GB direct in Mac and 2.6- 2.9 through Anker Dock.

Had my first one for over a year , working perfect . this is the second one I just bought . I have a MAC mini M4 & using apple thunder bolt 4 cable made by ( CalDigit ) , I get faster speed than advertised on some files . this device has been reliable & super fast . I would give it 9 ⭐️⭐️⭐️⭐️⭐️⭐️⚡️⚡️⚡️.

Great drive. Ok price, but for TB3-4 I guess its worth the price. The drive is fast.

Es súper rápido!! 100% recomiendo

lo uso para ampliar la memoria de mi Mac mini y funciona de maravilla. Lo recomiendo mucho
