Samsung 1TB 840 EVO SSD Review

Samsung 840 EVO 1TB SSD is one of the best values in a high performance SSD. We used it to upgrade a workstation class notebook in two ways. First, we used the included Samsung software to migrate from the existing SSD to the 840 EVO. Next we swapped out the Seagate Momentus drive for the Samsung 840 EVO.
We run multiple video editing programs and the entire Adobe CC suite on our portable workstation. As anticipated the biggest impact was seen after we replaced the 7200RPM with the 840 EVO. A typical editing project may range from a 200GB-600GB. Having the speed of the 840 EVO to more rapidly open, preview and jump around the timeline was certainly worth the added expense.
The 840 EVO does get fairly warm to the touch in operation. Nothing that impacted performance but that speed generates heat. The 1TB features sequential read/write speeds of 540/520 MB/s which is very good and competitive with the highest performing consumer drives available.
Flash memory technology is maturing and manufactures are using creative ways to cram more memory in the same amount of physical space. The 840 EVO uses triple level cell memory. Think of it as an apartment complex with more people living in each apartment. More people in each apartment means more light switches can be turned on and off simultaneously. Of course when you have so many people living so close together things can sometimes go wrong. There's less room to breathe so to speak. That's kind of the argument of why 3D memory might not be as robust SLC or single level cell memory.
The argument is becoming moot as all manufactures are on this tack to reduce costs and stay competitive. Basically, Samsung has found a way for those people, or Bytes of data to peacefully coexist and even thrive in the same amount of space. The 1TB 840 EVO offers a 3 year warranty which is decent for non critical use. With over provisioning and using less of the drive's actual capacity we anticipate good reliability.

Convergent Design Odyssey7Q Review
Published: Monday, 09 June 2014 22:27
The Odyssey7Q combines a high quality 7.7 OLED monitor with an SSD based recorder to allow the capture of high bit rate quality codecs such as ProRes, DNxHD, Sony FS700 Raw, Canonc500 4K Raw and other options available via pay firmware upgrades. We used it with the Sony FS700 to capture ProRes HQ at 220Mbps.
The file based workflow is all about flash memory. On our shoot we utilized a variety of flash memory. The Odyssey7Q requires Convergent's branded SSD. We also recorded the native FS700 files to an SD card inside the Sony, glad we did and more on that shortly. The DLSR and Sound Devices recorder used compact flash.
The OLED display on the Odyssey is very nice. It's large enough Before we go any further we have one work of advice for any file based acquisition day, redundancy. We recorded audio to both cameras and the Odyssey7Q as well as the Sound Devices Mixer. We recorded video to both cameras natively and Odyssey7Q.
Our shoot was a series of sit down interviews. Pretty straightforward. Once we were setup we let it rip and then it became more about data management. The Odyssey7Q recorded in chunks of 3.94GB for every 2:45 worth of roll. So after each interview we'd have about 8 files to assemble and cut. The 7D records in 3.99GB chunks for every 13:05. So a couple of files per interview and we'd interrupt the flow periodically to reslate. With a couple of SSDs it's easy to keep rolling while transferring files. We highly advise having a system with USB 3.0 to transfer the files and we're looking forward to Thunderbolt in the future. After a full day of shooting on the two cameras plus redundant files we had 600GB of data to manage.
The Odyssey7Q was easy to figure out and worked seamlessly for the most part. The 7.7 inch OLED makes for a good size touch screen. However, all is not sweetness and light. We encountered corrupted files for a portion of two of the interviews. Just flat out corrupt files. This is the gotcha in the file based workflow. When it goes bad it's just gone. It's not a few hits in an analog tape. The good news is we had the second camera and the native codec from the FS700 as a backup. However, for a field recorder that's approaching $3K in cost this is not acceptable. It's been years and years of SxS and P2 with and we've never lost a file to corruption. Devices like the Odyssey7Q need to be just as robust. And from our initial field test it appears they're not.
Our advice isn't to shy away from the Oddyssey7Q. This is where things are headed and we expect the folks at Convergent and industry as a whole to make these types of external recorder/displays as rock solid as P2 and SxS. For now remember our keyword for the day, redundancy. As you embrace new technologies that enable you to capture the most brilliant images possible, have a plan in place to capture at least an image, in case you happen to lose a few a long the way.
