[Chris Pearse] “I’m sorry to hear about your luck with these SSDs. I would certainly suggest using one of the recommended SSDs to guarantee compatibility. Unfortunately speed is not the only factor when using these disks with video data.

We have just last week performed some testing with the 128GB version of the Vertex 4, and indeed it seems to drop frames pretty quickly even with DNxDHD and ProRes on the HyperDeck Studio. I’m afraid we don’t know why this problem occurs, but we will continue testing SSDs for compatibility.”

Chris, thanks for the answer.
I offer again to send you a Vertex 4 256Gb for testing and debuging.

The 128GB is slower than the 256 and 512GB, so you have to test all of them.

I really don’t understand the “speed is not the only factor” sentence.
I can imagine the official ratings of the SSD are in “best state case” with max compression, but a lot of people tested out the Vertex 4 even without any compression, on a raw sequential write and almost beat the claim of OCZ.
On my side, the BlackMagic Disk Speed Test tool, with the SSD connected to a SATA 2 and a 5GB file test is OK for 10 bits RGB 4:4:4 writing, which is far more than the Shuttle should need. And this is with a SATA2 connection, limiting the bandwidth… A native SATA3 should do better !

I don’t want to make any harm to your business, and I’m willing to help, and it is MY fault if I ordered the wrong SSD, but still, I just don’t understand why it is not working… and I’m sure you’ll find a way to make it work !

Just don’t go for seagate drives, unless you don’t want to use RAID on your drives. I’m having problem with firmware and seagate don’t want to hear about it.
My advice : wait for some time to have 2To drives on the market and go with WD or Hitachi.
Then, put them internal if you can, or find an external enclosure – maybe with 4 plugs : Firewire 400/800, USB and eSATA.
Have a look at ProavIO or Enhance tech chich are making really good and cheap RAID enclosure.
