G-Tech’s G-SPEED eS Pro system of hot-swappable, large-capacity drives solves these problems in a sleek and cost-effective package. Available in a variety of configurations, the eS Pro series includes an aluminum enclosure design that houses four slots of removable 7200 rpm, 3.5-inch SATA II drives, each with up to 1.5 TB of capacity. Add this up, and each enclosure supports up to a massive six terabytes of space for video and files, with eS Pro technology available for 12- or 16-bay rackmountable chassis, which means daisy-chaining support all the way up to a massive 192 TB.When used with the optional, two-port G-Tech PCIe x8 IOP RAID controller (with 512 MB of on-board DDRII memory), RAID 0, 1, 3, 5 and 6 configurations (as well as JBOD) are available for tailoring disk arrays to the needs of a production. RAID 0 (striping) will alternate data between the drives for faster read and write times, clocking in on the eS Pro units at 424/395 MBps, respectively, with one unit and an incredible 833/786MBps with two bays (according to G-Tech’s lab trials).
If worried about data redundancy, the lab results also get impressive numbers at RAID 5, with 317/296 MBps on one unit and 664/663 MBps on two. Basic RAID 1 mirrored settings also are available for each unit, as well as parity and striping options with RAID 3, 5 and 6 for balancing the performance of the units with the absolute safety of files.
Storage capacities are available at up to 6 TB per unit, which is scalable up to 12 TB, and each terabyte holds up to 84 hours of HDV at 1080i, 17 hours of DVCPRO HD 1080/60i, 10 hours of ProRes 422 HQ or 2.25 hours of HD in 1080/60i. Performance itself is ideal for video-editing applications with transfer rates that are better than high-speed Fibre Channel rates, thanks to the locking 12 Gb mini SAS port and included two-meter SAS cable.
SAS architecture also supports multistreaming, and a single-enclosure eS Pro offers multistream playback of ProRes 422 HQ when used with four 7200 rpm, 3.5-inch SATA II drives in RAID 0 mode. Or the unit can run a single stream of uncompressed 10-bit HD, while two units (eight drives) in RAID 3 or 5 protected mode can produce two simultaneous streams of uncompressed 10-bit HD, or a single 2K resolution DPX digital-intermediate sequence.
Managed via a browser-based GUI, the software controls configuration and management through the web via any local Internet browser. Access is as simple as clicking on a URL, and the software monitors power-supply voltage, fan rpm and the temperature of the RAID controller and hard drives. Auto-rebuild is built in to cover a possible problem, and an e-mail can be sent to alert up to four recipients of a problem as well.
The units are Mac-friendly for intuitive operation with Final Cut Pro, with HFS+ formatting right out of the box, as well as support of Final Cut Pro’s ProRes 422 codec. Installation is as simple as plugging in a G-Tech PCIe x8 RAID controller to an available Mac Pro slot and plugging in the mini SAS cable to the drive. The units also are PC-compatible with support for Windows 2000/XP/Vista.
The enclosure keeps itself cool with thermoregulated cooling fans, designed to operate quietly, and the drives are sleek and compact with a small footprint of 8.25×4.9×6.5 inches. There’s a three-year warranty with unlimited, free technical support. Pricing starts at a list price of $1,999 for one unit with 4 TB of storage (without the RAID controller) or $2,999 for 4 TB (with the PCIe x8 RAID controller card). A G-SPEED eS PRO XL series also is available, with a 2U, 12-drive or 3U, 16-drive rack-mount enclosure, starting at $6,999 for a 12 TB system. Spare drives are available in varying capacities from 500 GB and up, starting at around $115.
