OCZ's Flagship SSD: Vertex 4 256GB Review

  1. "Once formatted in Windows, the original 256GB is converted to 239GiB, though Windows shows this as 239GB, so it seems like 7% of the original capacity has been lost."

    Drive capacity is base 10, 1 GB = 1000 MB, 1 MB = 1000 KB although a Byte is still 8 bits.
    Windows is using base 2, 1 GB = 1024 MB, 1 MB = 1024 KB and 1 Byte = 8 bits.

    256*1000^3=256,000,000,000 Bytes
    256,000,000,000/1024^3 ~= 238.4 GB

    1024^3/1000^3 ~= 1.074 aka the 7% difference seen.
     
  2. I have read in other reviews that the initial release of the 256GB Vertex 4 was to have 1GB of DRAM but only 512MB "turned-on" with later models to have simply 512MB...I didn't see that mentioned here or unless something changed between then and now. I also want to add that the controller in the V4 is actually a Marvell controller...the OCZ peeps over at their forums seemed pretty agitated when finally breaking down to confirm what a bunch of us already suspected; hence the phrase "Indilinx infused".

    ^ Call it whatever you want.
    Once again, OCZ's SSD's rick roll anything Crucial has to offer, especially for OS load time, game load time and multitasking.
    And the 5 year warranty puts a nice 'we just kicked your butt again' stamp on it.

    Vertex 4 and Octane use OCZ's Indilinx Controller with Marvell firmware, and the 1.4 firmware took the write speeds of the Vertex 4 to the next level for OCZ. The Vertex 4 256GB will be mine... oh yes... it will be mine.

    Indilinx Controller, Marvell modified firmware.
     
  6. Other than the price coming way down, great news as SSD's are now selling in volume.
    The read and write speeds aren't anything to write home about in today's market. Flagship model?
     
  7. Nice. Although I have the 512GB in my system, I only have one complaint and that's the firmware updating. Having to connect another drive and boot off that just to update the OCZ firmware is a pain in the butt.
     
  8. I don't know for Vertex, but Intel are good. I have 2 180gb 330 series and the 3 year warranty is for read/write 20gb/day. As for the 350 series, the warranty is 50gb/day for 5 years. Unless you are using it for data storage (which is small for that feat), it's still pretty good.

    You don't have to connect another drive to flash it. I flashed my 512GB Vertex 4 using the linux live tools for OCZ SSD's while it was the only drive plugged into the machine (other than an optical drive to boot from).​

    Future OCZ firmware upgrades will be non-destructible as well.

    I've got the Vertex 3, can I upgrade my firmware without wiping windows off the drive?

    Burty - I think it matters what your current firmware is. When I went to flash mine it told me that it was going to be destructive.
     
  13. My only complaint, no Vertex 3 performance included in that long list of SSD's for comaprison. Other than that, cool review.

    No Vertex 3 firmware update I've used has been destructive. They usually recommend secure erasing but unofficially you don't have to for any of them.

    Thanks Guys, I will cross my fingers, my Firmware was last updated when I first got the drive last year september time, I haven't actually checked to see if there is an update I just thought I'd ask the question just in-case I had to format the drive, thanks for the info.

    Using what measure? I hope you're not looking just at the sequential read/writes.

    damn your good! lol
     
  21. What the tests fail to distinguish is how the drive performs with less than 50% free space. From what I've read (Tom's Hardware), OCZ has a special optimization technology that is in effect when the drive has more than 50% free space. Once the 50% threshold is crossed, the I/O drops back from "performance mode" to "storage mode", negating the advantage over the competition.

    OCZ has been boasting "fastest SSD" by this little caveat. It really would have been useful to see benchmark tests with more than half the drive occupied with data.
