Performance vs. Transfer Size

ATTO is a handy tool for quickly measuring performance at various transfer sizes. While IOs in real world usually happen at specific sizes (mainly 4KB), it important to get a big picture of performance. The BP3 is able to keep up with read performance, but write speed is once again lacking. The SMART is unsurprisingly on par with Intel SSD 335, which is based on the same SF-2281 controller.

    The crucial mSata 256gb is pretty good for asrock z77-itx board and for intels h77 itx board.
    They allow for a small desktop. I would like the 3 mobos I used to allow sata III they only allow Sata II.

    Follow up

    I have these mobos

    ASRock Z77E-ITX LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Mini ITX Intel Motherboard

    Intel BOXDH77DF LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 Mini ITX Intel Motherboard

    ASUS Maximus V Gene LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard

    all are running with just the crucial msata 256gb ssds .

    I would not mind one with a Sata III slot , I do agree msata is not offered as viable option for the system builder.

    All I could find is that mSATA is only specified for SATA 1.5Gb/s and SATA 3 Gb/s, not SATA 6 Gb/s. Reply

    Forgive me if I missed it, but should there be a benchmark showing performance consistency when factoring 25% spare area? Given AT's recent affinity for such benchmarks, I now expect to see it in every SSD review.

    It's not something we test with every drive because for example all SandForce drives behave the same way. I've actually had these drives for nearly six months and tested them long ago but the write up was pushed back by more urgent reviews. I know I may sound lazy here, but I don't consider the BP3 or SMART to be the choice for many already given the fact that mSATA isn't very popular and I see the majority of buyers going with name brands, so I decided not to test performance consistency this time.

    The random write speed is rather slow to begin with, and it gets below 1MB/s when tortured.

    It would have been nice to see performance consistency benchmarks for the drive that used the Phison controller, especially since there are only a handful of options for ~250GB mSATA drives.

    It's great to see any sort of reviews of lesser known drives. At the same time, it's a little disappointing that the perceived popularity of these drives stopped you from doing a more complete review, especially if you've had them for 6 months.

    Yeah, I know it's not a proper excuse. This spring will be quite busy for me though, have plenty of SSDs to review and at the same time I should study for matriculation exams as well as university entrance exams.

    I know I shouldn't be making excuses, but I hope you can relate to my situation. I try to cut as few corners as possible but performance consistency is just PITA to test (well, the actual testing is fine but making the graphs is just painful because Microsoft can't make Office that's fully compatible with Office for Mac... Anand does the graphs on Mac, so I have to do too or they won't be identical). After that it's time for awful HTML editing which I suck at, so that takes way more time than it should.

    Well if this is the place where we ask you to do performance consistency tests before your exams I'm in :)

    I would just love to see how the most crappy SSD controller of all; the JMicron JMF602 fares in performance consistency.
    I think it would be a nice thing to look back at with what we know today.
    Shockingly SSD's based on such controllers are still being sold!

    Yeah I'd like to see the performance consistency for the lower end or even crap SSDs.

    Maybe even a few conventional spinning platter hard drives- low, mid, high.

    Unfortunately, I don't have any SSDs that old. The "worst" SSDs I have are Crucial v4, OCZ Agility 4 and Samsung SSD 470. I could definitely run something on the V4 and BP3 to see if Phison has done any progress in this matter. Reply
