The Daytona 256 is the first device to offer subnotebook users 256 MB of formatted storage capacity in a 12.5-mm-high drive for subnote- books and a 341 MB, 19-mm-high drive for notebooks. All four Daytona drives bring desktop PC performance to notebook computing with a fast internal data transfer rate of 36 Mbits/second. Daytona performance benefits from a common architecture shared with two Quantum families of high-performance 3.5-inch drives. Matching features include a multi-segmented adaptive cache, local bus support with fast multiword DMA and AutoRead and AutoWrite technology. The Daytona drives leverage most strongly off the design of Quantum's earlier GoDrive GLS line of 2.5-inch devices. They share GLS' highly integrated electronics, which consists of only five chips, as well as its firmware base. This leveraged approach to design eases qualifications and improves product availability. The Daytona drives feature exceptional ruggendness with a very high level of protection against non-operating shock. For energy efficiency, the drives comply with industry standards on power consimption, drawing only 0.2 watts of power in standby mode. Reliability Features ==================== ShockLock Pivoting Magnetic Latch --------------------------------- An innovative pivoting magnetic latch protects the drives from short- duration, non-operating shocks as high as 300 Gs, which is the high- est level of protection offered by 2.5-inch disk drives. The magnetic latch swings away from the drive's actuator to eliminate disturbances when inner tracks are read. Error Correction Code (ECC) On-the-Fly -------------------------------------- The Daytona product use a custom ASIC to implement a state-of-the-art error correction code that maintains data integrity at high through- put rates. Performance Features ==================== Adaptive Segmentation --------------------- The Daytona products feature Adaptive segmentation for more efficient cache use. With this feature, the buffer space needed for read and write operations is dynamically allocated, which yields higher throughput from a given buffer side. DisCache and WriteCache Firmware -------------------------------- DisCache firmware optimizes disk drive performance by speeding data access times and data retrieval, and increasing throughput. Quantum's proprietary WriteCache firmware allows the host-to-buffer transfer of data to occur while the buffer-to-disk transfer of a prior command is still executing. Upper 32 KB Buffer used for firmware. Power Conservation Features =========================== StackWrite Firmware ------------------- StackWrite firmware can save up to 13 percent of battery power while providing faster system response. The unique firmware accumulates write requests in buffer memory instead of directly onto the disk when the Daytona drives are in standby mode under battery power. AutoIdle and AutoPark --------------------- To conserve battery power, the actuator motor on the Daytona products can be shut down after five seconds of inactivity - without host intervention. With the new AutoPark mode, Daytona's heads are auto- matically parked over the dedicated landing zone when AutoIdle is initiated. ATA Compliance -------------- Daytona drives with an AT interface incorporate all the energy- efficient modes defined by ATA/CAM (AT Attachment/Common Access Method). Versatility Features ==================== MCC Compatibility ----------------- The Daytona disk drives conform to the latest standards of the Manufactures Compatibility Committee (MCC). As a result, the drives can easily slide into position and connect directly to a hard-mounted connector on a notebook's motherboard. AT Bus Cable Select Hardware ---------------------------- Automatic cable-select hardware simplifies disk drive installation by eliminating the need for a physical master/slave jumper. This is ideal for removable drive applications, when the same Daytona drive is a master in a notebook computer and a slave when used with a desktop computer. ********************************************************************** G E N E R A L ********************************************************************** QUANTUM ATA TIPS Comparing the Fast ATA and Enhanced IDE Disk Drive Interfaces ------------------------------------------------------------- Why are Fast ATA and Fast ATA-2 Important? Faster data transfer rates are important because a computer is only as fast as its slowest component. Today's 486, Pentium, and PowerPC-based computers offer processor speeds many times faster than only two years ago. Bus speeds have also increased with the inclusion of 32-bit VL and PCI local buses, which have a maximum data transfer rate of 132 MB/second. Faster buses mean that data can be transferred from the storage device to the host at greater speeds. Fast ATA and Fast ATA-2 allow disk drives to store and access this data faster, thus enhancing the other high-speed components in the system and removing the bottleneck associated with older ATA/IDE drives. In short, Fast ATA helps bring very high performance to desktop PC systems. In addition, when compared to SCSI, Fast ATA is the least expensive way to achieve faster disk drive data transfer rates and higher system performance. The implementation of Fast ATA through system BIOS provides performance without incremental hardware co sts. Older systems can support Fast ATA using an inexpensive host adapter. Fast ATA and Fast ATA-2 are easy to implement in either VL or PCI local bus systems. The hardware connection can be made using a standard 40-pin ATA ribbon cable from the drive to the host adapter. Direct connection to the motherboard further eases integration when provided by the motherboard supplier. Once connected, the high data transfer capabilities of Fast ATA can be enabled through the data transfer options found in most CMOS BIOS setup tables. Newer versions of BIOS provide automatic configuration for Fast ATA drives. Fast ATA can improve efficiency by allowing more work to be completed in less time because the computer moves data faster. Graphic, multimedia, and audio/visual software users will benefit most because the speed of those applications, which work with large blocks of data, are transfer-rate dependent. The Fast ATA and Enhanced IDE interfaces both use the local bus to speed data transfer rates. Enhanced IDE also uses the same PIO modes as Fast ATA, although a data transfer rate equal to the PIO mode 4 rate has not been announced for Enhanced IDE. The major differences between Fast ATA and Enhanced IDE are that the latter includes three distinct features in addition to fast data transfer rates. The additional features of Enhanced IDE are as follows: High-capacity addressing of ATA hard drives over 528 MB - a BIOS and device driver function. Dual ATA host adapters supporting up to four hard disk drives per computer system - a function of BIOS, operating system, and host adapter, not the drive. Support for non-hard disk drive peripherals such as CD-ROMs - a function of BIOS and the operating system, not the drive Each of these features supports improved functionality at a system level, a positive development for the industry and end users. However, support for all three features requires an extremely high degree of integration and revisions to operating systems and hard- ware, in addition to BIOS changes. Specific support is required not only for the storage peripherals but also for host adapters, core logic, the system bus, BIOS, and operating systems - virtually every major block of PC architecture. There is no central industry-supported standard that controls the features of Enhanced IDE. With no standard, some products sold as "Enhanced" may provide only one of the three features of Enhanced IDE. For example, fast data transfer rate support is be coming standard on mid-range and high-end local bus systems. This single feature could satisfy the users immediate requirements without the need for the other features of Enhanced IDE. In the future, if the same system is upgraded to add the remaining features of Enhanced IDE, users may be forced to purchase an Enhanced IDE package that contains a feature already installed. This could result in unnecessary costs, integration conflicts, and in- compatibility with original factory implementations. Fast ATA, on the other hand, represents only the fast data transfer rates for ATA hard drives (support for PIO mode 3 or 4 and DMA mode 1 or 2). Fast ATA and Fast ATA-2 data transfer rates can be easily achieved when the system BIOS and hard drive suppo rt the PIO and DMA protocols. BIOS that supports Fast ATA does not necessarily support high- capacity addressing, dual host adapters or non-hard drive peripherals. But these features are being introduced independently by system manufacturers in order to compete in the PC marketplace. All of Quantum's disk drives designed for PCs now support Fast ATA, and new products with Fast ATA support will be introduced in early 1995. The drives are also fully backward compatible with older ATA/ IDE (non-Fast ATA) BIOS. The Quantum drives support both the Extended CHS (Cylinder Head Sector) and LBA (Logical Block Address) addressing methods in overcoming the 528 MB DOS capacity barrier. Quantum drives can also be used with dual host adapters. Finally, there are no incompatibilities with Quantum hard drives that would prevent computer systems from supporting non-hard drive peripherals. Quantum drives that support Fast ATA include the following families: Quantum ProDrive LPS 170/210/340/420 Quantum ProDrive LPS 270/540 Quantum Maverick 270/540 Quantum Lightning 365/540/730 Quantum Daytona 127/170/256/341/514 Fast ATA and Fast ATA-2 are important technologies that can take advantage of the performance provided by the latest high-speed microprocessors and bus architectures. The high-speed interfaces are based on industry standard specifications and are the least expensive way to achieve faster disk drive data transfer rates. Fast ATA is not a group of features that requires an extremely high level of integration, and only represents the fast data transfer rates for ATA hard drives (PIO mode 3 or 4 and DMA mode 1 or 2). =====================================================================
