AnandTech Storage Bench 2011 - Light Workload

Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).

The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:

Our light workload remains Samsung's safe haven with the 840 Pro. OCZ's Vector does improve performance considerably over the Vertex 4 (+25%) but Samsung manages a 16% performance advantage here with the 840 Pro.

    Its way too large for a msata drive, so it wouldn't fit anyways.

    Why is there an mSATA connector on the PCB anyway?

    The PCB is far too large for an mSATA drive anyway, so why have the mSATA connector?

    That's likely a custom debug port, not mSATA.

    Take care,

    Actually that connection is indeed a physically identically sized/compatible m-SATA connection. The problem is it's inability to actually plug in due to the SSD's general size or whether it's able to communicate with the typical m-SATA ports on mobos. should give a decent example.

    might be a sign of something else in the works from ocz like an msata cable to plug into it or something, maybe something even more awesome like double the band width by connected it to a ocz pci break off board. i guess we will see

    I have a Vertex2 256GB SSD.
    Is it worth upgrading to a Vector or a Samsung840 Pro SSD ?

    If you've got a motherboard with SATA 6Gb/s you would probably notice a difference. Whether it's worth it is up to you - do you do a lot of disk-intensive work to the point where you wish it were faster? While I'm the difference would be noticable, it might not be huge or worth spending $200+ on.

    Are you often waiting for your disk to finish tasks? If not it's not going to be worth it.

    It's going to take more than a nice type written letter to resolve the many product and service issues at OCZ - if they stay in business over the next six to 12 months.

    FYI- A five year warranty ain't worth the paper it's written on if the company no longer exists. In addition a five year warranty does not mean that a particular product is any better than a product with a one year warranty. For each extended year of warranty, the product price increases. So you're paying for something you may or may not ever use.

    In addition it's useful to read the fine print on warranties. Most state that you will receive a refurbished or reconditioned replacement if your product develops a defect. If you've ever seen some of the "reconditioned" or "refurbished" mobos from Asus or similar products from other companies, you'd never install them in your PC.

    People reach many untrue conclusions about product quality based on the warranty.
