eS3-PCIe24 - Key Features

  • Four eSATA (External SATA I II) ports (6Gbps - compatible with 3Gb PM bridge)
  • Support MAC 10.x built-in AHCI, WindowXP to Windows 2012, Linux Kernel 2.6.x
  • 4x lanes PCI Express V2 connection offering 20Gbps bandwidth
  • Supports Port Multipliers with FIS based switching or Command Base
  • Connect up to Twenty drives via SATAII or SATAIII Port Multiplier including SATA Drives, ODD or SSD
  • 6Gbps eSATA III External 4 Ports PCIe Gen2 or Gen1 x4 Lane Host Adapter
  • Support SATA Hot-plug capability, Native Command Queuing (NCQ). Windows and Linux OS booting

Using up to four lanes PCI-Express Gen 2, eS3-PCIe24 provides a 20Gb/s data channel that harnesses the total speed of up to twenty (20) hard drives, allowing manufacturers to take full advantage of the speed and plug-and-play convenience of external SATAIII.

Over 1300MB/sec transfers have been measured with four sBOX-eS configured as RAID0.
The eSATA ports on eS3-PCIe24 is a 6Gb/s port, fully compliance SATA III spec, making them ideal for connecting multi drive storage solutions through Port Multiplier bridge boards old 3.0Gb or newer 6Gb/s PM bridges.

Support for FIS Based Port Multipliers
The eS3-PCIe24 supports port multipliers using FIS based switching. Traditional SATA controllers only support CMD based switching which can only access a single drive at a time, limiting performance to that of the drive being accessed. The eSATA-PCIe8, based on AsMedia 106x chip-set, supports FIS based switching which accesses multiple drives simultaneously, effectively aggregating the bandwidth of all the drives, including CD/DVD/BD drives.

Our test shows 20x drive RAID0 via four sBOX-eS - SATA III Port Multiplier enclosure - read/write of 1300MB/a can be achieved

Our eS3-PCIe24 offers 4x independent 6Gb/s eSATA is an indispensable host controller that provides FAST and COST effective solutions for massive storage
