The PM chips spec out at ~250MB/s.Does this enclosure reach the 250MB/s throughput? Would be a nice addition, if not replacement for my current box.
I've got a similar 4 bay enclosure but it levels off at 115MB/s. Cost 160 without eSATA card.![]()
The box itself can actually get close to that (4 disks, not 5; check here). If you take a closer look at the graph, you'll notice 2 models. Those are kits, and the only difference is the eSATA card in the kit (the SIL3132 is slower, while the other, based on a Highpoint 2314 <Marvell chip>, gives much higher throughputs). What do you expect for a super cheap card...?
Your card is the suspect, not the box.
You may want to consider the Newertech card that supports PM chips, as it's cheaper than the Highpoint 2314, and uses a Marvell controller chip as well <6.0Gb/s btw> (OWC has it on sale).
