USB4 cases and docks

[Hardcore Games]

I have a recent Dell Latitude 5440 which supports USB4 so it can reach 40 gigabit speeds with devices such as 8K cameras and displays

I have 1 TB SSD in it and best it can have is 2TB. My machine uses M.2 2230 nas it is 14" in it a tad crampt.

I have a 12 TB WD hard disk uib a Orico USB 3.0 box which works at 5 gigabit speed which is enough for the hard disk. The vendor says the box can support up to 16 TB disks. I am thinking of getting some larger capacity hard disks but I see capacity limitations are common.

Anybody get a 24TB disk working in a USB box? Searching google finds lots of overpriced M.2 boxes.

Yes. I am surprised by capacity limitations - isn't the USB interface just a bridge to SATA ? At least that's how it works with Linux, and any SATA compatible drive should work. Maybe they just tested it up to 20TB at the time of the release.

Looking up online SATA uses 48bit for LBA addressing which ought to be enough for more than 128000 TB with 512B sectors.

I agree that LBA48 is standard but I am also wondering by LBA did not leap to LBA64 yet.

NTFS is still mired in 32-bit, ahj old USB 2.0 box choked above 8TB which is why have an Orico box which is USB 3.1 and operates at at least 5 gigabit

LBA22 emerged by WDC in 1994, so LBA48 surfaced in 2002. LBA48 evidently is 128PB but 64-bit makes more sense simply from a 64-bit platform troday.

Maybe simply because by the time we have drives with more than 128PB they will be using different connectivity. Judging by this datasheet, they were just recently extending M.2 ssd drives with support for 48-bit addressing:

I agree that 128PB is a tad bigger than the SSD in my Dell laptop

I was looking at all classes of storages such as USB sticks, USB hard disk and USB SSD etc, lots not forget about tape too
