Tempo SATA E2P
2 Port 3Gb/s eSATA PCI Express Host Adapter

Are you planning to incorporate external data storage in your computer setup, but need a SATA host controller card to make the connection? Install a Tempo™ SATA E2P-it's an affordable solution for adding external SATA ports that enable you to hook up single2 and multi-bay SATA drive enclosures for your mass storage needs.
Why the Sonnet Tempo SATA E2P?
SATA drive enclosures offer flexibility not found in fixed drive installations inside a computer. Many offer swappable drive trays, which are perfect for managing daily backups and multiple projects, and most are portable. Some enclosures, like Sonnet's Fusion™ D500P and Fusion D400Q, feature port multipliers, which enable up to five hard drives to communicate with the host adapter through one cable. Not all host adapter cards support port multipliers, but Tempo SATA E2P does-through its two ports, this card can handle up to ten1 drives!

Tempo SATA E2P is versatile. It is Mac OS X, Windows Vista, and Windows XP compatible and supports the RAID features2 of Mac OS® X, Windows XP Pro, and Windows Vista. It also supports hot-swapping of drives3under Mac OS X. Installation is simple-just plug in the card to any available PCI Express® (PCIe) slot, start your computer, and install a driver. When you need to add flexible, portable storage to your setup, Tempo SATA E2P gets you connected.

  1. Support for 10 drives requires the use of drive enclosures employing port multipliers (like Sonnet's Fusion D500P, Fusion D400Q, or Fusion R400P). When using an enclosure without a port multiplier, Tempo SATA E2P will support 2 drives.
  2. SATA drive hot swapping is not supported in a desktop or server PC running Windows XP, Server 2003 or Vista. A SATA drive appears to the system as a not-removable hard drive and there is no mechanism in Windows to prepare the drive for removal.
  3. Sonnet Tempo cards are compatible with most external SATA storage. However, external hard drives with USB 2.0/eSATA dual interface based on the Oxford Semiconductor OXU931DS storage controller chip may not be compatible with Mac OS X when connected via SATA. Known issues are kernel panics occurring when the drive is connected, or the drive not being recognized by the operating system.

Rating: 5/5 Excellent addition! January 27, 2019 This is the mid-range PCIe card that added e-SATA capability to my 2012 MacPro six-core. It was a simple plug-in and use item. My real-word data transfer time using 256mB files was 90mB/sec, which was 3x faster than FW-400 or USB 2.0. The card appeared to be well-built, and had a clean layout.

I would recommend this item to a friend! Customer Videos:

Rating: 5/5 Still supports Power Mac G5 (with PCIe slots) October 22, 2014 I have an old Power Mac G5 from "late 2005" (dual-core with PCIe slots), which I still find quite useful (and reliable), running Leopard. It's great that I can add this new capability to an old PowerPC Mac, running an old OS. The current price tag is a bargain. This is now my first Mac with eSATA ports.

It works with OWC's Voyager S2, which is an older version of the hot swap "dock" for SATA drives (with USB 2.0 and eSATA connections). File transfer speed is at least as fast as between internal hard drives on built-in SATA I bus (far faster than USB 2.0). It may be faster, but my testing was limited to timing the transfer of a large file from an internal hard drive to the eSATA drive, so the bottleneck was probably the internal SATA I speed. But that's fast enough for my purposes...

I also tried with a newer Voyager Q ("quad" interface including eSATA), which I recently bought for use with my "other" Mac. With either eSATA device, I was able to unmount the hard drive's volume from the system, physically "eject" it from the dock, and then re-dock it, "on the fly."

The OS sees connected devices as being "Parallel SCSI." Volumes connected through eSATA cannot be used as the startup disk. Unlike USB and FireWire, the eSATA port does not supply power, so any connected eSATA device must have its own power supply.

I would recommend this item to a friend!

Rating: 5/5 This is the one to get if you want to hot swap December 20, 2011 I had purchased the NewerTech one at a similar price at the same time I purchased the Voyager Quad interface "toaster" for using my loose external SATA hard drives- no need to run installer- great. The NewerTech esata pci addition to my Mac Pro requires a system restart when changing the hard drive in the enclosure. That means I need to close all 10 or 15 programs that are running and reboot the computer just to do a fast backup using the esata connection.

With this Sonnet Technology card installed I can eject my hard drives just as easily as when the usb or firewire connections are used. It can be used easily for all backups but cannot be used for system startups because the Mac system apparently doesn't allow external esata drives to do that.

I would recommend this item to a friend!

Response from MacSales.com, Marketing December 23, 2011 Regarding "the NewerTech one" referenced: On a Mac, Hot Plug/Hot Swap is supported in OS X 10.7.2 and later. Due to a bug in Apple's AHCI implementation, previous OS versions do not reliably support this feature.
