E-Disks(TM) SUD35 and SCD35 Improve Random Access Throughput 1,000

Times More than the New Generation 15K RPM HDDs in NAS Environment

BiTMICRO NETWORKS today unveiled E-Disks(TM) SUD35 and SCD35 with up to 75.7 GB in 3.5-inch form factor -- the highest capacity and the fastest Solid-State Flash Disk in the world.

Rated at 9500 random I/Os per second (IOPS), 48 usec random access time and 34 MB/sec sustained random read and write transfer rates, the solid state E-Disks SUD and SCD are ideal for "Hot Files" caching.

"Hot Files" usually comprise less than 5 percent of application's database but account for more than 50 percent of I/O waiting time. By adding the SUD/SCD E-Disk as an architectural solution, overall system performance will improve significantly.

In general, the E-Disk SUD and SCD solid state storage devices are great I/O and throughput performance booster for DAS (Direct Attached Storage), NAS (Network Attached Storage) and SAN (Storage Area Network) architectures and RAID configurations -- by either replacing the hard disk drives used or acting as a cache or parity disk.

"Using the new generation of 15K RPM HDDs in NAS environment as baseline, Netbench 6.0 Random Performance Test results demonstrate that our Ultra Wide SCSI E-Disks dramatically improve random access throughput by more than 1,000 times," said Dave Bultman, VP of engineering and operations. "The test results are consistent and the random write throughput improvement becomes even more significant as the number of users increases," Bultman added.

Besides having higher performance, the desired small form factor, reliability (2 million hours MTBF), and ruggedness (16.4 G rms and up to 1000 Gs of operating shock), BiTMICRO's E-Disk offers additional security and data protection features required by these applications and not offered by any other flash-based SSD.

High-performance E-Disk brand of solid-state disks advantages compared to other flash-based SSD products include:

1. Intelligent auto-wear leveling feature that increases the

wear-out life by ensuring even distribution of the erase/write

cycles over the entire flash device.

2. Only flash-based SSD in the world that records statistics that

allow itself to "heal" from various failure types. The

statistics are also used to inform the host of potential

future hard failures before they become unrecoverable.

3. The PowerGuard(TM) option prevents data loss and corruption

due to ungraceful power degradation or failure.

4. Other features are: flash memory scrubbing, error-correction

code, failure monitoring, and automatic bad block re-mapping.

All of these features are transparent to the user since they work in the background without affecting the system's performance.

The E-Disk brand storage devices are fully compatible with Linux, Solaris, Windows, MacOS and LynxOS using standard drivers. It also supports AIX, FreeBSD, HP-UX, IRIX, NetBSD, OS/2, QNX, VxWorks, SCO Unixware and OpenServer, Solaris x86 and Tru64.

BiTMICRO E-Disk brand solid-state disks flash-based family: Highest storage capacity; 100% data integrity without battery or HDD backup; industry leadership in performance and reliability.

Available now, the high capacity 3.5-inch E-Disk SUD/SCD storage devices are ideal solutions for any mission critical application requiring performance, reliability, and/or ruggedness.
