I wonder how fast is will be.

Should be slower than HDD. Write all 400GB will take quite a bit of time 😛

Even at max speed, it will take more than an hour to write the entire SD card once. For normal photos, it should take around 2 hours to import 400GB data from this card 😀

Anyway, this may be a good reference on how fast the card can go.

Could still be useful as a Time Machine or manual backup. A lot cooler than spiiner HDD's too. Someone should make a PCIe adaptor for 10 of these cards . .. 😛

That would be very cool... You could RAID 0 them all.... 😀

Any device where 4kB block read and write goes as far down as show in the table from h9826790 is no fun. I'm using SD in some old Indy Workstation with an SCSI2SD Adapter. While the SCSI Controller is limited to 10 MB/s, even this tiny link can't be saturated by the SD cards performance. However, regarding noise and heat, it's a good solution and the old Indy Workaround is not about speed at all. 🙂

So if anybody is expecting SSD like speed from an SD-Card … well, don't.

Stranger things have happened . . . not so long ago Ultra SCSI was God .. then RAID . . SATA SSD's . . then M.2 PCIe blades . . . recently ASUS released a 4 blade M.2 PCIe board - end of spinner HDDs for me at least.

What's next ?

Power management & case heat too . .my previous 2,1 cMP was so expensive to run power wise so the cMP's from 2009 suddenly had much smarter power management.

Perhaps someone somewhere is busily reverse engineering some cool alien technology 😵 . .

I just cannot imagine the specs for 2025 desktops . . . .
