1. Introduction The Unigen Orion Series of Solid State Drives is designed specifically to address the demanding performance and reliability requirements of Enterprise‐Class storage and computing applications. 1.1 Product Overview Built with a SandForce 2281 controller, the Unigen Orion Series SSD is ideal for energy‐efficient computing, reducing access times, and provides a durable alternative to conventional hard disc drives with superior shock resistance. The proprietary space manager architecture in the controller maximizes read/write data rate performance to and from the host and flash memory, eliminating firmware delays during sector read and write operations. The SandForce flash processor, combined with tailored firmware, provides complete ATA disk emulation, which ensures complete compatibility with a wide range of operating systems. Designed for ultimate reliability, Unigen Orion Series SSD’s have an excellent 2.0 million hour mean time before failure (MTBF) ensuring reliability over long term usage and come backed by a 3‐year warranty and dedicated technical and engineering support for OEM clients. 1.2 Block Diagram
1.3 Architecture The Unigen Orion2200 Series SSD’s are designed to fully utilize the SATA III 6.0 Gbps bus and the 16 byte wide lanes of NAND Flash.

Description Raw error rate related to ECC errors. Correctable and uncorrectable RAISE errors are included in the error event count. (UECC + URAISE) Tracks the total number of retired blocks. Data is calculated as 100‐ (100*RBC/MRB), where RBC is the retired block count and MRB is the minimum required blocks. Also an indicator of remaining life. Count of hours in power‐on state. The raw value of this attribute shows total count of hours in power‐on state. This attribute indicates the count of full hard disk power on/off cycles. Counts the number of flash program failures. Counts the number of flash erase failures. Counts the number of unexpected power loss events since the drive was deployed. Returns the percent difference in wear between the most‐worn block and least‐worn block 4 bytes used to show the number of program failures there have been. (Identical to attribute 171.) 4 bytes used to show the number of block erase failures since the drive was deployed. (Identical to attribute 172.)

Description This attribute tracks the number of uncorrectable RAISE (URAISE) errors reported back to the host for all data access commands. Temperature assuming an on‐board sensor connected via ISTW interface to the SF‐2200. This attribute tracks the number of uncorrectable errors (UECC).
This attribute tracks the number of blocks that fail programming which are reallocated as a result. A measure of the estimated life left, based on a combination of PE cycles and available reserve blocks. 100 is a new drive, 10=replace as it has sufficient reserved blocks but the PE cycles have been used, 0=insufficient reserved blocks, drive is read only to allow recovery of data on the drive. Indicates the total amount of data written from hosts since the drive was deployed. This is stored in 4 bytes. The number stored represents the number of bytes written by the host to the drive, in 64GB increments. Indicates the total amount of data read to hosts since the drive was deployed. This is stored in 4 bytes. The number stored represents the number of bytes read by the host to the drive, in 64GB increments.
