Product Description:
When it comes to data storage capabilities, which do you prefer, raw storage capacity or scorching performance? With Sonnet Technologies' Tempo SATA E4P, you get the best of both worlds! This card offers unprecedented scalability through its support of port multipliers - it can handle up to twenty drives! Used with high-performance drive enclosures like Sonnet's Fusion 500P, port multipliers manage the data flow of up to five drives in one enclosure through a single cable. Using today's highest-capacity drives, you can connect an astounding 10 Terabytes (10, 000 Gigabytes!) of storage!Tempo SATA E4P delivers performance previously unattainable with mainstream technologies. The PCI Express interface offers huge bandwidth for data throughput, so the card never slows you down. For the utmost performance, you can create multiple RAID arrays to capture and process uncompressed high definition video, or conquer other high-bandwidth applications. For fantastic flexibility, you can work with 20 drives individually and hot-swap them out as needed. You can even work with a combination of RAID arrays and individual drives - your choices aren't limited. When your storage needs have outgrown standard solutions, get a Tempo SATA E4P - it'll give you room to grow and blazing performance for the most demanding applications.

I have used other e-sata cards and had trouble in Leopard Mac OSX. This card has been working great

Great card, but one significant complaint, April 28, 2007
By M. Caswell
I'm using this card in a Mac Pro. Performance is fine, and the card does pass SMART data and temperature to OSX (several other cards that I tried don't). Unfortunately, drives connected to this card never spin down. Doesn't matter if the computer has sat idle for hours (with the internal, and Firewire drives having spun down), the eSATA drives keep spinning. Same thing when the computer is put to sleep, or when the drives are unmounted from the desktop.

Sonnet tech support confirmed that the card blocks HD sleep commands.

It's not a deal-breaker, but still a disappointment.

Fast, Reliable, Flexible, February 20, 2007
By R. B. Currier (Sunny California, USA)
I've been using the E4P for over a year in a Mac Quad G5 system, controlling both a small single-drive enclosure and a 10-drive RAID system.

I was a bit hesitant to go with a port-multiplier system, thinking that it would adversely affect performance. But both disk subsystems perform extremely well, with the RAID able to sustain uncompressed 1080/60i HDTV without a problem. You could probably get a bit more performance by not using the port multiplier, but then you are limited in the number of drives you can connect, since the densest SATA controller I know of is just 8 ports.

I'm satisfied enough with this that I'm ordering another to install into a new Mac Pro (Intel-based) system.
