Innostor Technology IS611 (Taiwan), this is a USB 3.0 SATA+IDE Bridge Controller, first release at
2013.
This brand
was a chip manufacturer of several USB Bridge Controller, up to the year
2019.
At that year the brand decided to end their activities, due the fact that their profitability shrink, because USB 3.0 products market this started to shrink too.
Innostor IS611
latest revision specifications cannot be found, their website this is not active anymore.
First revision IS611 (2013) this was supporting:
— Support for 2TB drives
— SATA II, 3Gbps and SATA I, 1.5Gbps
— ATA/ATAPI-7 Spec (PATA UDMA-6 133MB/s)
— Firmware update via USB port
— Hot plug support
— Simultaneous use of three drives
— Support for USB 1.0, 2.0, 3.0 (rev 1.0)
Nowadays, IS611 chip (remaining stock) this still circulates within several almost identical products of USB 3.0 SATA+IDE Bridge's.
The only difference this is revision of firmware in use, and the issue might be maximum HDD size support.
Old revision supported 2TB, a later revision supported up to 4TB, and in theory the latest revision supports up to 6TB.
While LogiLink AU0028A (product of 2018) this mention.
*Max. SATA HDD Capacity: 10TB
*Max. IDE HDD Capacity: Depending on the IDE HDD
Regarding USB 3.0 bandwidth, while the theoretical maximum, this is 5Gbps, this controller supports SATA II 3Gbps.
SATA II 3Gbps equates to about 300 MB/s theoretical bandwidth.
Real world MB/s for USB 3.0 this is 215 MB/s at USB 3.0, and 42 MB/s at USB 2.0 port (benchmark SSD Kingston SA400S37/240G (240GB)).

I have an eye to such a modern controller for some time, as I was looking to also buy a USB 3.0 capable controller.
Because my older USB 2.0 to IDE, this was having a great difficulty to support a stable connection with my 2TB WD Gold HDD.
Even so, my older USB 2.0 to IDE, this it did succeed to format both of my new HDD a year ago.
November 2024, I found at sweet price this controller and I did ordered one.
And soon I will be able to perform a detailed analysis.
Supported hardware:3.5" IDE Port = HDD , CD-RW, DVD-RW (with molex plug connected too)
2.5" IDE Port = HDD
SATA II port = HDD, DVD-RW?
Supported software: Windows format
HDD utilities Low-level format
Notes: * Innostor IS611 chip provides S.M.A.R.T. data only for SATA disks.
* IDE drives must be jumpered to "Master"
