Dear fellow eSATA user
Has anyone got the
IOT-SATA102 eSATA card working successfully with the
Welland ME740J: USB2/eSATA 3.5" HDD enclosure or some other external device?
Love to hear your feedback!
After doing some research, we contacted the suppliers & manufacturers, however they could not confirm if the two had been tested and have not yet supplied a HCL (Hardware Compatibiliy List) for alternative devices.
Our view is that the card was either faulty or incompatible 
. For testing purposes, we purchased a different card, which worked straight away without any issues
Lycom ST-113e Low Profile Serial ATA PCI Card
which uses:
Silicon Image SiI3512 chipset:
Here is a basic performance comparison between USB & eSATA,
with our results showing that eSATA is significantly quicker (almost 3x):
Code:
hdparm -Tt /dev/sda1
USB:
Timing cached reads: 1396 MB in 2.00 seconds = 697.47 MB/sec
Timing buffered disk reads: 84 MB in 3.02 seconds = 27.78 MB/sec
eSATA:
Timing cached reads: 1372 MB in 2.00 seconds = 684.90 MB/sec
Timing buffered disk reads: 226 MB in 3.01 seconds = 75.11 MB/sec
eSATA also works with
SmartMonTools
To display HDD status:
Code:
yum install smartmontools
smartctl -d ata -a /dev/sdb1
...
SMART overall-health self-assessment test result: PASSED
...
More information:
The Welland ME740J uses the
SATALink SPIF215A-HF021
(USB2.0 to SATA Host Bridge):
We chose this model, since it received the best
review out of nine enclosures,
refer to the
Vantec NexStar3 NST360SU:
Hope this info helps someone out there.
