Three External USB And eSATA Blu-ray Burners Tested

By

The advent of affordable, high-capacity media could bring a renaissance in optical storage, but only if the performance is adequate. We tested a few of today’s fastest drives with USB and eSATA connectivity to find out where this technology stands.

BD-R Dual-Layer Write Performance

Verbatim’s dual-layer discs are also quite fast, though most drives can’t push these to the limit.

Asus climbs to 8x almost instantly and stops there, averaging 7.46x for the entire burn.

Using eSATA, LG’s BE12LU30 takes a little longer to reach 8x and settles for a 7.13x average using Verbatim’s 6x discs.

Plextor reports P-CAV, but appears to use Z-CLV for Verbatim’s dual-layer 6x media, resulting in a slower 5.55x average.

Dropping to USB 2.0 hurts LG a little, though at 5.48x average, it’s still nearly as fast as Plextor.

On the other hand, eSATA doesn’t help Plextor’s PX-LB980UE whatsoever.

    pirateboyno LiteOn device? why?The eHBU212 wasn't available yet when this roundup was initiated last spring. Sorry, other reviews had deadlines.

    Yeah, LG drive looks really cool and performs better, nice design and lavish looking

    Could you please add a chart about the quality of the burned data itself.
    (I do not know if this is possible?) A lot of people still burn audio CDs and for this the burn quality is normally essential

    dimarWhen do we finally get eSATAp?It's been replaced with USB 3.0, and neither of those has enough amperage to power these drives.

    Not true. http://en.wikipedia.org/wiki/ESATAp
    I already have the bracket for eSATAp where I have the power supply connected using the 12v/5v molex cable.

    dimarNot true. http://en.wikipedia.org/wiki/ESATApI already have the bracket for eSATAp where I have the power supply connected using the 12v/5v molex cable.That's fine, but it doesn't contradict what I said.

    Let me be more specific: USB 3.0 is primarily for portable devices, eSATA is primarily for stationary devices, and eSATAp is something in the middle that doesn't have enough power for "big" drives such as these.

    The purpose of eSATAp WAS to combine the convenience of USB 2.0 with the performance of eSATA. But the purpose of USB 3.0 IS to combine the convenience of USB 2.0 with the performance of PCIe. This is a was vs is debate, Windows XP is still great too but many people have simply quit using it.

    Hey, I remember external SCSI too!

    BTW, some of these drives DO support eSATA. Forget the P, a USB power connector won't power these drives!

    You don't get it. You actually connect the power supply power cable to the back side of the eSATAp connector. It gets the full 12v and 5v load.
