I recently purchased a Dell M6600 that came with a 512GB SSD Samsung PM830. Apparently the OEM version of these drives are not supported by Samsung and it appears to not support firmware updates, or they just are simply not released. I ran a bench mark for performance for a database class I am in and I found a staggering difference between the retail Samsung 830 128GB SSD and the Dell OEM Samsung PM830 SSD both support trim and are sata-3. The difference is mostly just on the 4k random write test.
For the two 830 4k random write results
512GB PM830: 8.49MB/s 2,173iops
128GB 830: 53.75MB/s 13,761 iops
This is a huge difference. The moral for me is don’t buy the OEM upgrade SSD drive. If you can’t update the firmware on SSD you in for trouble.
After failing to talk my school into registering for a free vmware school account so I could score VMware workstation 8 I decided to purchase it. I primarily wanted the feature that they somewhat promoted that allows you to share your virtual machine with other people.
It sounded like a really awesome idea however I couldn’t seem to find any video on the internet that would demo it so I put together a short demo of the sharing feature and how it works. Overall, I was pretty impressed. It would be a great function for school or having a shared machine on the job where developer could debug code at the same time or share the experience more seemlessly then a go to meeting.
