    Is the 120GB Samsung SSD that came with my M4400 considered slow by comparison to other SSDs now? I can't find any particular specs or comparisons that use this drive, but when I see other drives getting 200MB+/second, I know I'm not getting anything near that.

    Also, is this a "first generation" drive that doesn't take advantage of Trim in Windows 7, etc.?

    Also, I've tried searching for new drivers and firmware, but I don't see anywhere. I have Windows 7 64 on it now, and I've experienced a few BSODs, which is why I'm looking into possible driver/firmware causes. (Though I was also getting these occasionally in Vista 64.)

    Not as fast as an Indilinx or an Intel, but still faster than any conventional notebook HDD. Furthermore, unless you're doing some really disk-heavy jobs, you probably won't notice a significant performance difference between an RBX and a faster drive. I know I don't.

    And no, the drive doesn't support TRIM, but it doesn't really degrade all that much over time. I'm not sure if you can update the firmware, but I'm betting your BSoDs are a Win7 issue, and not one with the drive.

    Do you have any sources or benchmarks on that? I just got what I thought was a PB22-J chipset samsung ssd that turned out to be an older RBX series drive, and I need to decide whether I want to pay a restock fee to send it back. If it's not going to stutter (never perform worse than a HDD, even for small writes on a "dirty" drive), then I'll just keep it. If it is, I want to send it back.

    It's like 90/70 MB/s sequential R/W and about 4-5 MB/s random 4KB writes. I say it's not a fundamental issue with the drive (though if the drive is defective, it's a different story) as I've been running a 7 and an XP desktop (the XP desktop even runs 24/7) on RBX MLCs for months now without any problem.

    Thanks for the help! +rep. I got a good deal on the drive anyway, so I think I'll just stick with it. Save some money both on the restock fee and on buying a new, more expensive drive.

    Looks like a few other people here with the RBX drives say they work great too, so I shouldn't be worried. I figure it'll beat the pants off a 5400rpm laptop HDD regardless. Thanks. :)

    Yeah, I feel like the RBX gets an unfair amount of bad press due to it's age and the relatively (compared to Indilinx and Intel) poor performance of the PB22-J... back in the day it was the X25-M of its generation, the drive with which you couldn't go wrong.

    Generally, I still don't think there was/is a noticeable performance difference between my old SLC RBX and my X-25M G1, at least not in day-to-day computing. They're both much better than conventional HDDs, to the point where, practically, faster just doesn't mean that much.

    I see similarly 90/70 MB/s of read/write speed on my RBX 128G. I know it's much slower than new SSDs from Intel and others, but I think for most workloads the difference in spec won't lead to real-life difference. It's because seek time (0.1 ms) is the most important metric in most usecases (like browsing, document, programming, small graphics task, not-so-heavy multimedia, etc).

    A firmware update with trim support for the Samsung PB-22J is now available here.

    I'm generally happy with my PB-22J. Read speeds are impressive and power consumption is low. However, the time to hibernate is no better than with a HDD.

    Um, the RBX series is not a PB22-J chipset. So no TRIM.
