OCZ Vertex 4 SSD on Fedora Linux Benchmark

Posted on 2012/10/26 by Luke Hollins

I needed more space for something so I grabbed a 256GB Vertex 4 to replace a 128GB. Looks promising so far , write speed is much faster , almost 100MB/s over the 128GB . See OCZ Vertex 4 128GB

OCZ Vertex 4 SSD Benchmark on Linux

Posted on 2012/05/11 by Luke Hollins

Just got one of these OCZ Vertext 4 SSDs to replace an Agility model which was pretty amazing. The write speed is advertised as slower but more consistent with different kinds of data. bonnie++ run:

Note you should update the firmware on this drive before using it, they doubled the write speed on some models recently. I installed version 1.4RC before formatting the drive. You can get it here: http://www.ocztechnology.com/ssd_tools/OCZ_Vertex_4/ The only bad part is they don’t have an updater for Linux or iOS, I had to use a friends windows box to run it.

If you have never used an SSD I would look for a cheap SF-2281 or Indilinx 60-64GB they can be found for $50-70 now. Assuming you aren’t lacking in RAM or have a five year old CPU, its the single biggest noticable upgrade you can make to a computer. A browser loading in a split second becomes the new normal. Copying an 8GB virtual machine image? Don’t go get a coffee, its done in 20 seconds.

OCZ Agility 3 SSD on Linux (Fedora, benchmark too)

Posted on 2011/12/15 by Luke Hollins

This is the 60GB OCZ Agility 3 SSD , with an ext4 fs. I have been using it as my root disk on Fedora 15 for a while now. This one’s an RMA replacement , the first one was BSOD city on another machine and wouldn’t even get detected by my machine’s BIOS. This one has had so issues and supposedly OCZ’s fixed their SF-2281 based drives.

It gets 480-500MB/s with iozone. But I think it was using RAM caching (some tests got 8000MB/s).

I just got one of these, it’s ripped out of a GoFlex drive.Had to use parted , delete mbr with a gpt table then create fs. This was using ext4 of the whole disk

Steve Jobs Was Right

Posted on 2011/06/16 by Luke Hollins

I hate to agree, but Flash sucks, it’s always sucked and it will never stop sucking. It doesn’t belong on any low-powered device where battery life is a concern and leaking memory is unacceptable. Flash is the only thing that consistently crashes my phones. I’ve overclocked them 150% , installed questionable kernel versions and test apps that I was sure would cause a crash. But again and again, Flash on websites always crashes.

But what does work amazing? Not apps. The open web. Yeah it doesn’t look that great in many cases. But mobile apps are a step backwards. Remember when the PC/Mac app users gradually moved to using the web instead of apps? The gradual move away from vendor-lockin, multiple compilers/targets, inability to view your own data and general incompatibility is bound to come to phones as well. The question is how long will it take?
