    Hi,

    I was thinking about upgrading my laptop to an SSD. The path I'd most likely take is to get an ODD caddy, put the current drive in it, and put the SSD in the primary bay. I am then planning to get an external ODD case and putting the blu-ray drive in it.
    The question is whether USB 2.0 is going to cut it for blu-ray movies, or should I rather look for USB 3.0/eSATA solutions? Input is welcome.

    I believe BDROM is about 4.5MB/pass, so a 6x BDROM should go ~27MB/s, I wouldn't try it on USB2.0.

    USB 2.0 = 480 Mb/s = 60 MB/s

    Blu-ray maxes out at about 54 MB/s so I read..

    This seems pretty close. Unfortunately external ODD cases faster than USB 2.0 are hard to come by on this side of the pond.

    If your USB2 ports can sustain 60MB/sec for 90 minutes then by all mean go ahead. Also tell me where you bought them because those are decent sustained speeds for USB3 (depending on what you're doing).

    Should be no problem. Blu Ray was around for a few years before USB 3.0 was out and there weren't any issues with it.

    I have read that even a 2x reader will play them, so that makes sense.

    Looks like I was worrying for no reason then. When it comes to SSDs, it seems that samsung 840 pro is quite a beast, except for 2 drives dying for the anandtech guys. Will that drive shine in P150HM?

    It's the fastest drive out right now, but also one of (if not the absolute) priciest.

    The Intel 520 series are also very good, and great reliability. The 840 Pro is pretty impressive though.

    I just checked and the price of 240 GB Intel one is the same as 256 GB Samsung. I'll wait until the Anandtech situation clears up though.

    Impressive drives, but is the premium in price going to give you that much more feeling of performance over say an M4?

    You all know that 840 are dying/melting faster than the current ones, they are based on TLC tech rather than on MLC.
    The good news about 840 is that it puts pressure on the SSD prices and drives adoption, in fact their prices should go
    down once they are adopted widely. The performance of 840 is just a marketing gimmick. But I might be wrong.

    Blu-Ray Movies require 54 M bps, that's Mega BIT per second not Mega BYTE per second. That's about 7MB/sec. USB 2.0 can easily handle those speeds. Even though max theoretical speed for USB 2.0 is 60MB/sec, realistic is about 40M B/sec but still, well above what is required.
