The fastest and largest 2,5" form factor solution (with spinning drives).

Hi,

I'm looking for a fast 2,5" 4TB+ solution to copy 4K red rushes. SSD's are in use but they need to be offloaded at the end of the day and i'm looking for a portable solution that is reasonably fast. The average shooting day is 500-800 GB and this needs to copied twice.

I tested the Seagate Fast STDA4000200, a 4TB drive that reaches speeds of 200 MB/s.

I'm wondering if anyone knows what else is out there? Better or faster solutions?

Many Thanks!
K.

You didn't say how you're connecting your drives, but more importantly, you will never find a single spinning hard drive faster than the 200MB/sec you've already found. If you want faster throughout you'll need a RAID with two or more drives striped together. A good rule of thumb to remember is, every time you double the number of drives in a striped set you effectively double the throughput.

I concur with David - more spindles = better speed.

You don't mention how you wish to connect, but of you have a SAS HBA with an available port (4 channels), you could use something like this chassis from iStarUSA:
https://www.amazon.com/iStarUSA-SATA-Hot-Swap-Cage-BPU-350SATA-RED/dp/B003Y...

Populate 1-4 of the bays with that Seagate drive and stripe them. You would then connect the ports on the back of the chassis to the SAS HBA Port with a cable like this:
https://www.amazon.com/CableCreation-External-26pin-SFF-8088-Cable/dp/B013G...

Or, if you can go to 3.5" drives, you could use something like the SansDigital XR4T and get your storage out to 40TB and over 750MB/sec sustainable with Seagate's 10TB enterprise class drives (we use a number of these in our lab).
https://www.amazon.com/Sans-Digital-TR4X-Storage-Enclosure/dp/B002AKKDBY/
https://www.amazon.com/Seagate-Enterprise-Capacity-Cache-Internal-ST10000NM...

If you are limited by USB connectivity, you could use something like this as your chassis for 3.5" drives:
https://www.amazon.com/Mediasonic-External-Drive-Enclosure-HFR2-SU3S2/dp/B0...
Or This for 2.5" drives:
https://www.amazon.com/Noontec-TerraMaster-D5-300-Enclosure-Support-Diskles...

The iStar HDD cage that's mentioned by Tim is not an external device. It goes inside a PC cabinet and needs an SMPS to power it. and it uses 3.5" drives.

For 2.5" drives you could consider a 2.5" RAID case from Akitio which has removable 2.5" drives.
Like this one
Akitio Thunder2 Quad Mini
https://www.amazon.com/Akitio-TBQM-TIAA-AKTU-Thunder2-Quad-Mini/dp/B00VJ4IW...

It has no RAID capabilities, however.

There's the Promise Pegasus M4 which is tiny and supports 2.5" SSDs and drives.
