Now, measuring performance of a Hyper-Duo combo system is different because the usual benchmark tests only tell you what speed the regular hard drive is achieving, not the combo.

So, for somewhere around $100 you could buy a SYBA controller card plus a 60GB SSD and combine them with your existing regular hard drive and have a modern, fast system even on a 4 year-old SATA II motherboard. We put a Seagate hybrid in our laptop and it's quick & snappy!) Hyper-Duo works with any size SSD. (You can buy an SSD-Hybrid drive with 1TB capacity but the included SSD chip on hybrids is limited to around 8GB.

Basically, it lets you install Windows and all your apps and games on a regular hard drive, and it copies all frequently used files onto the SSD for fast loading. The SYBA SD-PEX40054 (and some other add-on cards) also include an optional Marvell "Hyper-Duo" SSD-cache feature (similar to Intel Smart Response).
Installed on an ASUS P6TD Deluxe motherboard (Intel X58 chipset, Socket 1366, PCI-e rev.2.0, onboard SATA II only), the SYBA card plugged into an x4 slot.Ī Sandisk Extreme 240GB SSD (8 months old, 42% full) achieves the following max. Regarding the Marvell 9230 controller chip and, in particular, the SYBA SD-PEX40054 add-on card, i can provide the following from personal experience. (you lose something in "overhead" there). Put two SSDs in RAID 0 configuration on an x2 controller card and you can get around 750MB/sec., maybe up to 800MB/sec. Some add-on controller cards also offer RAID. A SATA III SSD (most of them come with a SATA III cable).ĭepending on which SSD you have you may expect maximum sequential Read/Write speeds of around 500MB/sec. so you will be using the x4 slot or higher, NOT the x1 slot.ĥ. However, most motherboards have x1 or x4 or x8, etc. 2 lanes of bandwidth means the add-on card needs an x2 slot. An add-on SATA III controller card with at least 2 lanes of bandwidth (or more).Ĥ.

not enough bandwidth for full SATA III speed.ģ. An x8 or x16 slot is also OK.Īn x1 slot peaks at around 380MB/sec. If your computer has only PCI-e rev.1.0 you'll get roughly SATA I speed.Ģ. Check your motherboard's specifications ! (PCI-e rev.2.1 is also OK.) If you want SATA III speed from an add-on controller card you MUST have the following:ġ. So, he could have bought any add-on SATA III controller card, even a $1000 model, and he still wouldn't get the results he hoped for. But, the Precision 490 was a 2006 model with PCI-e Revision 1.0 that has only half the speed of PCI-e Revision 2.0 (which became available later in 2007). The add-on card was installed in a Dell Precision 490 - a good workstation PC. He felt he was suckered into buying the card and others chimed in saying the controller chip is basically crap, etc.īut everyone missed the OBVIOUS explanation. Having bought an add-on controller card to get better performance for his SATA III SSD the poster was unhappy that he actually got lower performance than his onboard SATA II ports offered.
