Wow!
I just got the drive (8TB U34 Bolt) , reformatted it to APFS.I used the cable that came in the box (although I bought another one just in case, a dedicated tb4 cable as I read it might be slow with the original cable.)Used black magic to test the speed and wow!Write 3083 read 2897 !!!!Now I need to see how it works when actually using it, I bought it to backup a MacBook Pro Max 16â 8TB (128Gb RAM).But really impressed with the speed.I wish 8TB NVME would be cheaper but I guess you get what you pay for and my other option was to get a WD SN850X 8TB NVmE and put it in an enclosure, would have probably cost 200 less but WD said they canât guarantee it would work, although it should but it needs to be connected to a motherboard.I donât want to take any risks and the casing on this U34 feels solid.

A real Thunderbolt external drive!
I have a new Mac Studio computer that has 4 real Thunderbolt4 ports, yet finding an external drive with a Thunderbolt4 is difficult to find. I did not want a Thunderbolt 3. I needed a 4TB external drive and this company had 2TB and 8TB on sale but not the 4TB. I would have loved the 8TB but it was expensive and overkill. I could not wait so I went ahead and bought the 4TB anyway. I am using it now for my Time Machine backups as my Time Machine had told me a 2TB USC drive I had was too small. I would not have needed a Thunderbolt 4 for Time Machine so if I later get a USB-C drive in 4TB I could use that for Time Machine and keep this drive for my photos and such. It was very fast doing a full first time, Time Machine backup. I am very pleased with it. It had good reviews but a couple mentioned how big it is. Itâs not tiny but still small, about the size of a deck of cards, maybe slightly thicker because of the rubber bumpers on it to protect it, but in no way big! My Thunderbolt ports are on the back of my computer and I just sit this behind next to my ports. I am thrilled with the drive just wish the 4TB would have been on sale as well.

Built like a Tank, Faster than a Ferrari
Pro’sThunder Bolt 4No Thermal ThrottlingNo Cache ThrottlingIncredible Drop ProtectionCon”sFor me, None, The drive performed as advertised.Out of all my SSD drives for Production this one is the fastest hands down. I have always struggled with drives slowing as they fill up or they get overheated, NOT this one.I did speed tests when it was completely empty and, then I dumped 4TB worth of Arri Raw files onto it via Offshoot. The speeds were still within 10% of each other, Incredible… I don’t plan on dropping my drives anytime soon however, this thing is built to take a hit… The entire housing is milled out of an aluminum block and covered in a silicone sleeve for protection and heat dissipation.

Catastrophic Experience – Lasted only 3 days
The drive looks well built and also very fast. I trusted the positive reviews… Problem is that it lasted only 3 days.. from my standpoint utterly unreliable. The problem happened when I was writing some metadata on some pictures and suddenly the drive locked itself in read mode. The drive can still be mounted and the data previously written on the disk is readable but only in read mode. Impossible to delete any file, to format or erase any partition also at low level because the drive report I/O errors. So I find myself in the situation where I have 350G of sensitive material that cannot be erased before returning and at the same time the drive cannot be used anymore because all writing is blocked due to the I/O errors. Support didn’t have any tool to do an internal diagnosis of the drive, just suggested, low level partitioning from Windows or Linux with Parted Magic which works as a dedicated bootable Linux distribution that I did but with no success as the HW failed. I would never trust it for any serious workload.

Fast and reliable
So far this hard drive is excellent. It is fast and I love the portability and bumpers. I shoot photography and video professionally for large clients and have used this for tethered shooting, backups and shuttling footage between servers with no issue. I’m extremely happy with it.

Thank god
I bought this and used it to backup my other Lacie drive. Well, that lacie drive crashed after about four years just yesterday. Glad this had my data. All my work was saved. It is FAST. Much faster than the thunderbolt Lacie.

Blazing fast!
Very pleased; drive is exactly as advertised. 1TB transferred (over USB4) in under 10 minutes. 4TB transferred (USB A – USB4) in just over 9 hours [more than half time of previous]. And, it never even felt more than slightly warm to the touch; and is whisper quiet.This is my first purchase of an Oyen product; and I am extremely pleased. I searched looooong for a high-volume SSD with the most current tech available. The U34 Bolt appears to be my answer. I’m unaware of any other product available (beyond self-build – at approx. 4/5 the cost) that even comes close to the specs offered by this SSD. 8TB USB4 NVMe2 PCIe4 for under $1K is a bargain, in the current market.I will stay alert of price drop (as others catch up), and re-buy at a greater deal.Bonus: über-fast shipping – arrived one week early!

So much better than others I have …
Oyen makes good products but I feel like one is exceptional. SUPEERRRRR fast and zero issues with data loss. Really happy with editing off of it … used it for hours with no hiccups in Final Cut Pro on my Mac Studio M1 Ultra. I have this 4TB and a 8TB and both are good.
