Just finished - now I can get back to work. That's a record for me. Moving from a 2x5TB RAID to a single 10TB NAS drive.

Run Diskwarrior first, transfer second.



Saint Cloud, Minnesota, where the weather is wonderful even when it isn't.

8TB does not transfer in double digits of minutes. Hours is pretty good.

Not many people here with $ to blow on that type of setup. Sure, it's possible but not even with a very expensive 4x NVMe setup:

only 5GB/sec where Hal would have needed 6.5+GB/sec. Sustained including small files, not peak on those large files and on both sides of the transfer, read and write. Not gonna happen.

Sure, EVERYONE has a 10TB striped SSD RAID. I suspect you mistook TB for GB.

You can do upwards of 8GB/s with a SSD striped RAID. You can easily hit the 1000MB/s with fast platters. Sure, if you have a pair of 7200 rpms in a RAID 0 that is going to take a day, but it is pretty inexpensive to do it a lot faster.

I think you're having a nerd stroke.

Seriously - I was just posting my experience in transferring a bunch of data. It was a big deal to me. Yes - 2 7200 RPM RAID to a single drive like I said in this OP. Please think of me when you dump your 10TB SSD RAID for upgrade.

Single NAS drive. I was thinking he was moving to a larger NAS unit with multiple drives, but that was not the case.

I might have gotten the same drive, a Seagate Ironwolf 10 TB. I am averaging ~130 MB/s backing up to it over USB 3, estimated 5.5 TB in 10 hours.

Maybe in 6 years a 40 TB SSD will be cheaper than a similar capacity hard drive.
