The G-Technology's 4TB G-SPEED eS 4-BAY RAID Array with four 1TB Enterprise Drives is an economical, high-performance, high-storage solution designed for professional video content creators. The compact and whisper-quiet G-SPEED eS sports a 3Gbit eSATA interface great for transmitting the large amounts of data demanded by video files. It also features four 1TB hot- swappable Hitachi Ultrastar 7200 RPM SATA drives for the memory you need to store video and to speedily and easily access it for streaming.
Since an eSATA host adapter for connecting the unit to your computer is not included, you have two options for deciding on one. If you decide to use another company's port multiplier aware eSATA host adapter, you can configure the G-SPEED eS as only a software RAID or a JBOD. As your second option, if you use G-Technology's PCIe 4x RAID controller, you will have a much greater variety of RAID options. The controller allows you to configure your G-SPEED eS as a RAID 0,1,5,10 or JBOD. As such, you have more flexibility in choosing the right configuration for your work, whether you need more storage, extra reliability, simultaneous access to video files, or some ratio between the three.
When used with this controller, it supports multi-stream SD, ProRes 422 and uncompressed HD workflows. For example, a single G-SPEED eS used with the G-Technology controller supports up to four simultaneous streams of ProRes422 HQ or one stream of uncompressed 1080/60i. Moreover, in terms of just storage capacity, one terabyte of memory holds up to 84 hours of HDV 1080i, 17 hours of DVCPRO HD 1080/60i, 13 Hours of 8 bit SD, 10 hours of ProRes 422HQ, 10 hours of 10 bit SD and 2.25 hours of HD 1080/60i.
When used with G-Technology's controller, you can setup your RAID configurations and monitor your system via an easy-to-use, web-based graphic user interface. Accessed via any internet browser on your computer, this simple GUI can easily keep track of your RAID's performance and, in the event of a disk failure, have the G-SPEED eS alert you via email.
Along with this safety mechanism, the G-SPEED eS features locks for each drive, a sturdy aluminum casing and two internal fans for preventing the hard drives from overheating. In addition, the G-SPEED, itself, will sound audible alarms in case a disc fails, the internal temperature nears 140deg.F, a fan stops, a fan spins too slowly to cool the system, or when the enclosure is improperly disconnected from the G-Technology PCIe RAID controller. Beyond all these exceptional features, should you ever decide 1TB of memory isn't enough, you also have the option of scaling up in a few different ways.
You can replace all of the drives in the G-SPEED enclosure with 2TB drives (because you can't mix and match them) for 8TB per enclosure. In this case, you can still use another company's host adapter or the G-Technology PCIe RAID controller. With the latter, you can also both upgrade your enclosure to 8TB and connect up to four G-SPEED eS enclosures at once. With another company's host adapter, you might be able to connect up to four, depending on what their card allows. If you do go for the maximum amount of scalable memory using at least the G-Technology controller, you can connect four enclosures of 8TB apiece for a total of 32TB of memory! All told, the 4TB G-SPEED eS is an economical, high-storage, high-performance RAID hard-drive array designed with all the right features to keep you, the professional video content creator, busily at work!
