Connect an ultra quick external SATA device to your computer with this 12-inch SATA to eSATA cable! This cable features an internal SATA connect for connecting to your motherboard and an external eSATA connector so you can add an SATA device such as external hard drive to your computer!Features/Specifications:

Most CRU products come with all the data cables that they can make use of. But if you need extras or replacements, we have you covered. CRU has cables in many lengths and connection types to fit your unique set up. These cables are identical to the ones your product was developed and tested with, so you know you're getting the connectivity you need.

Optiplex 755 + new WD My Book 1TB drive. Seen via USB2 but not via 3rd party SATA cable to backplate + eSATA cable to drive. BIOS External SATA set on (this option only appears to be displayed when the drive is connected - does not need to be powered on) ==> drive ID shown as unknown (not sure how significant this is).

Here you will find the top quality and reliable Serial ATA cable that we specially picked considering the regular usage and connection requirements. Moreover, you can use these cables for multiple storage devices such as HDDs, SSDs, Optical drives, and so on. Not sure how to pick the right SATA / eSATA Cables, then feel free to contact us.

SATA has become the ubiquitous connection to hard drives in both laptops and desktop PCs. SATA is available in two basic forms, internal and external (eSATA). Both forms use seven conductor cables with two balanced pairs and grounds between the pairs. In addition, eSATA can be used for runs up to 2m in length and adds shielding to the cable. Many laptops and desktop computers have an eSATA connector to be used with an eSATA drive. Current data rates of 3.0Gbps can transfer data up to 10x the speed of USB 2.0 drives. Unlike the ungainly parallel cables, SATA and eSATA cables are thin and flexible, and relatively easy to handle.

SATA and eSATA transfer data at 3.0Gbps, or 300Mbps. The eSATA signal is usually derived from a standard internal SATA port. This signal is propagated down a PC board and sent to an eSATA connector. Many hosts do not have the drive capabilities to accommodate the losses of the board, connector, and cable.

The MAX4951BE overcomes the issues of mating an eSATA port to a SATA connection. The MAX4951BE drives the eSATA cable and enhances the signals in both directions through equalization. Input equalization (EQ) and output preemphasis (PE) both improve the signal quality. Both board traces and cables exhibit a lowpass filter characteristic; a typical board or cable can exhibit a -3dB point at 600MHz. Since the board or cable losses are frequency dependent, the ideal match would be a device that compensates for the high-frequency losses. With eSATA, the system must deal with signals moving in two directions: one signal goes from the host to the storage device, and one returns from the storage device to the host.

Figure 1 illustrates a typical placement. The controller hub (host) is several inches from the MAX4951BE. The host drives several inches of board or cable to the eSATA connector, and then a 2m eSATA cable to the hard drive. The signal from the host may just pass internal specifications; the signal can be as small as 400mVP-P. It then travels over from 3in to 9in of board to the connector. Sometimes this signal is connected to the board with a flex or ribbon connector, and losses of 1dB to 7dB are not uncommon. In that case. a 400mVP-P signal will no longer pass eSATA output level requirements. In addition, the high-frequency rolloff will introduce dependent jitter (DJ).

The signal in Figure 2A easily meets eSATA requirements. If the signal needs to drive ribbon or flex cable or a long FR-4 run to reach the connector, it will need help. Ribbon and flex cable make a nonideal link for 3.0Gbps; they introduce more losses, high-frequency rolloff, and jitter. The MAX4951BE has an optional setting to add PE to the output. PE improves the high-frequency response of the signal after it leaves the chip and travels to the connector. PE adds amplitude every time that a bit transitions from a 1 to a 0 or a 0 to a 1. See Figure 2B. Each time a transition bit occurs, the MAX4951BE supplies extra energy to this bit with PE enabled. The extra high-frequency energy helps to overcome high-frequency losses in the connector and cable/socket assembly; it should be used if the MAX4951BE must drive a difficult run to the connector. The designer can plan the board with a pullup resistor to pins 8 and 9. If the eye at the eSATA compliance points in the eye diagram is closed, then add the pullup resistor. If the signal shows a great deal of overshoot at the socket, then PE is not needed and the pullup can simply be removed. The MAX4951BE has internal pulldown resistors so these pins do not need resistors to ground. For the signal return to the host, there is no compliance point. A good "rule of thumb" would be to use PE if there is > 5in between the MAX4951BE and the host, or if the signal must traverse several vias. The "bump" in Figure 2B shows the increase in high-frequency content for a transition bit. The oscilloscope screen shot shows excellent performance for driving a long board run or cable.

The SATA/eSATA connector contains three ground pins, pins 1, 4, and 7. To automate power-down, simply lift one of these pins (e.g., pin 1) from ground and tie pin 18 to it. When a cable/hard drive is connected, then our example pin 1 will be grounded through pins 4 and 7, thereby enabling the MAX4951BE (Figure 4). If there is concern about the high-frequency portion, the designer can simply put a 5nf capacitor from pin 1 to ground, thus AC grounding the pin. When no cable is connected, the MAX4951BE is operating at nearly zero current; with a hard drive plugged in, then the MAX4951BE functions normally.

This article describes how to use the ReadyNAS backup job manager to back up data from an external disk connected via eSATA cable to your ReadyNAS. The disk connected via eSATA cable is referred to here as an eSATA disk. This process can be useful if you have an eSATA disk with a lot of data that you want to copy to a share in your ReadyNAS.

The SanDisk Extreme does not come with bundled software to help users transfer files from their old HDDs to the SDD. This means users will have to do this using an eSATA cable before or after installing the drive. I would probably do it before, and back the data up to a third drive, in case I muck up the transfer. 041b061a72
