netgear readynas 日前停产全线nas产品，取而代之以全新产品线

readynas原产品线繁杂

家用系列有duo, duo v2, ultra，ultra plus四个系列
其中，ultra系列使用了atom单核处理器，前者使用了arm处理器
ultra plus使用了双核处理器

商用系列有nv+, pro等
其中pro全线使用了atom双核处理器

上周五，本人在美国amazon上看到使用atom处理器的readynas ultra 2居然只有$199
联系了代购，确定代购回国内只要￥1600RMB左右。国内taobao上售价最低也得2400多呢[/color]

大喜，今天准备下单，却发现价格又变回$289.99了。

疑惑中上readynas官网一看才发现，旧品已经没有了，新品出来了。

新品的特点是产品线简洁。
家用的只有2款产品，102和104（2盘位和4盘位）
商用的只有4款产品。

家用的使用了最新的arm处理器 Marvell® Armada 370 1.2GHz
这款处理器虽然主频只有1.2G，但是带有FPU浮点计算单元！且有乱序执行能力！
性能比原6282的2.0G主频的要强太多了。

商用的清一色的是atom双核2.1G的。

软件上也做了更新，版本上升到了6.0，内置的功能大大加强：
随机的应用有：
•Replicate
•Time Machine Backup
•ReadyDLNA
•ReadyDROP
•DropBox
•ReadyNAS Vault
•iTunes
•Tivo
•Anti-Virus
•Remote
•Plex
•Photos
•Surveillance

可供下载的应用有：

marvell 370 cpu特性：

The Marvell® ARMADA™ 370 is a highly integrated and high-performance ARM V7-based system-on-chip (SoC) suited for a variety of home and enterprise applications. With its on-chip floating point engine, 256K L2 cache, and multiple I/O peripherals, the ARMADA 370 provides new levels of performance, integration, and efficiency, while enabling a simple system design. The ARMADA 370 is suited for a wide range of applications, including SmartHub for Home, networked attached storage (NAS) devices, media servers, and wireless access points, as well as networking and education applications.

The SoCs integrate:
• High-performance, dual-issue, and out-of-order ARMv7 CPU with Floating Point Unit (FPU) operating up
to 1.2 GHz (3000 DMIPS)
• Single/double precision FPU (VFP3-16) IEEE 754 compliant
• 32KB-instruction 4-way and 32KB-data 8-way, set-associative L1 cache
• 256KB unified 4-way, set-associative L2 cache/SRAM
• 16-bit DDR3/L-1333 memory interface
• Two Ethernet networking MACs controllers
• Four SERDES lanes with versatile muxing options for SGMII, PCIe2.0, and SATA2.0
• Two x1 PCI Express 2.0 interfaces
• Two SATA Gen2.0 ports
• Two USB 2.0 host/device ports with integrated PHY
• Network security engine with various encryption algorithm support
• Two TDM channels
• SDIO/MMC, NAND flash, two SPI, two TWSI, Device Bus, I2S/SPDIF and two UART interfaces
• Two DMA/XOR engines with two independent channels per each engine
• RTC and thermal sensor
• 286-pin HSBGA 19 x 19 mm, 1 mm ball pitch, green-compliant package


    The innovative Coherency Fabric architecture provides a coherent interconnect between the CPU and the I/Os. The bus efficiency also enables a high-frequency, high-bandwidth, and low-latency access time throughout the CPU memory subsystem.
    The on-chip Mbus architecture, a Marvell proprietary crossbar interconnect for non-blocking any-to-any connectivity, enables concurrent transactions among multiple units. This design results in high system throughput, enabling system designers to create high-performance products.
