Addonics Controller Overhead - 1 x 250GB on Port 0
Let’s run through the same battery of tests, but this time using the Addonics RAID controller. We should get a good idea of the overhead from the extra components.
First ATTO:
Notice that the performance is almost identical. There's no significant reduction in sequential throughput when we insert the RAID controller between the motherboard and the disk.
HD Tach shows a similar story:
Latency has increased by about 0.2 ms - that's 200 micro-seconds. That's almost nothing even in computer terms.
HD Tune Pro also demonstrates the same results:
The Addonics controller is not increasing the latency of the requests significantly. Throughput is also effectively identical with less than 1% separating one result from the other.

|70.114.239.xxx |2009-12-30 06:46:59 outcast2k - product review gaps?good start on covering some of the basics. some other detais that would be good to know:
1) how long does a RAID rebuild take?
2) how do you tell how far a rebuild has left?
3) how do you tell which disk failed?
4) does the software UI handle 2+ HDM-XA's in the system?
5) how do you recover the RAID if the HDM-XA itself has failed and needs to be replaced?
6) what's the biggest sized drives supported? 2TB?

|219.90.134.xxx |2010-03-07 23:17:32 TERRABYTEONE - ?? 3132 pciex1 card max output is 190mb/seciv tested this.. etc..
sil 3132 pci-e x1 card )(addtronics one) or jmb 363 or highpoint 4 port x1 2300 raid card.
max oot put is 190mb sec total.. and if using 2 ports its 95mb/sec..
tested this using 4x volir wd 300g hdd
(they get each 109mb/sec)
so if using both e-sata ports.. transfer maxes out at 190mb.sec..
if using 4 hdd in raid 0 etc... max output for 4x vr 300 on intel on-board raid (x48 chipset) 500+mb/sec..
on sil using this product is.. 90mb/sec.
als tryed 4x 1.5 tb 7200.11 hdd..max out at 90mb/sec
also tryed raid 5.. 90mb/sec.
2tb hdd supported. but hardware or nonhardware raid the sil raid gear does not support partitions bigger than 2tb.(old design)
to get 6 tb hdd spac out of in i raid 0 (4x 1.5tb)
i hd to make 4 partitions .. the software is limited in what size to make. it..it was tricky.. i had to make partitin/volumns 2+ then delet and recreat smaller ones. in aparticular order.
they need to update thar raid cards. (chan...
