Random Read/Write Speed

This test writes 4KB in a completely random pattern over an 8GB space of the drive to simulate the sort of random writes that you'd see on an OS drive (even this is more stressful than a normal desktop user would see). I perform three concurrent IOs and run the test for 3 minutes. The results reported are in average MB/s over the entire time:

Random write speed looks to be a bit better with the new firmware. The 80GB G2 being a little faster than the 160GB version for some reason. With enough free space, the Kingston SSDNow V performs similarly to a non-TRIM enabled X25-M G2.

    Do what I did. Buy a Gen 2, clone your drive, and sell the Gen 1 on ebay while it's still worth as much as it is. You will easily get close to $200 for the 80 gig version. I lost $30 upgrading, which was very worth it for TRIM support and the newest hardware.

    I must be misunderstanding you so please let me make sure I have this right...

    Someone bought your USED G1 for $30 less than you paid for your NEW G2!?!

    what cloning software did you use?

    I guess I couldn't switch to another SSD at the same time due to needing to clone the drive and using the same drivers between both SSDs?

    I used Carbon Copy Cloner on the mac, but Acronis TrueImage would work fine on PC.

    Acronis True Image is probably the easiest for Windows, especially if you're cloning to identical sized drives. With the trial you can do this for free, I believe Seagate and WD have simplified free versions if you have one of their drives installed.

    Don't mess with any of the backup/restore options, go to the Utilities and choose Clone drive, then select destination and source drives. Takes about 10-20 minutes depending how much data you have and is effortless.

    OK, Thanks!!

    sudo dd if=/dev/da0 of=/dev/da1

    Boot up into Knoppix and it is legitimately free.

    No kidding. I clone my drive every once in a while on my fileserver with dd. Why it's made so difficult in every other OS is beyond me. I really shouldn't need to buy software in order to make a copy. It's a pretty basic function, really.

    Just that the aforementioned software isnt primarily a cloning software but a backup and image software. Cloning a disk is just a minor function of it. And no, cloning a disk isnt a worthwhile backup strategy for most people.

    That said, I backup my system and data on a daily basis, but I only clone a drive once maybe twice a year. I wouldnt mind if it was built into windows, but its far from a necessity.

    This is nothing new, it has been well known for many years that there is a price to pay by being an early adopter.
