Ps just found another which is the top 4 port card that is the 88SE9230 its Syba which to be honest I think imports and rebrands IOcrest, but many do as how many companies where really Foxconn?
and £40 with free delivery is cheapest I have seen yet.
This one has some interesting options RAID 0/1/10 and AES Encryption 128/256-bit apart from the 6 port industrial one this is the top chipset in that series.
Also Marvell HyperDuo where you can pair up a ssd & hdd to make a 2 part hybrid drive which is extremely interesting as it always struck me that the ssd cache was always doomed to fail far before the hdd in a hybrid drive.
I just purchased one.
The Marvell HyperDuo offers a breakthrough embedded technology for new generation 6Gb/s SATA Controllers,
enabled on the Marvell 88SE9230 and 88SE9220. Based on years of research and patent-pending software and
hardware, HyperDuo enables 80 percent of the performance of an SSD at less than half the cost. Configured with
one hard drive and multiple SSDs, HyperDuo uses intelligent algorithms to automatically migrate hot data to the
SSD while enabling all data to be safely stored on a larger capacity SATA HDD for higher input/output operations per
second (IOPS), throughput and capacity.
The Marvell 88SE9235 and 88SE9215 can be used for embedded platform applications such as home NAS/media
servers, DVR/NVR and set-top boxes, or by HBA vendors to develop their own RAID software or in-box OS drivers.
Fully programmable on-chip transceivers support SATA, eSATA, and xSATA at 6 Gb/s and are backward compatible
to 1.5 Gb/s and 3 Gb/s. Built-in support for SATA Port Multipliers with FIS-based switching ensures maximum
performance. The small footprint of the device, and the few required external components, take up minimal board
space, easing system design and reducing cost. Embedded enclosure management via I2C protocol, further reduces
system cost.
