EC2 HA data storage backup solution EBS snapshots are an incredibly valuable tool if you can wait. But if you have any significant amount of data you need to restore you may be disappointed with the 4 megabytes per second recovery speed.
Scenarios in Which AWS EBS Snapshots Will Kill You
Resizing a EBS Volume — You are generating tons of space and you realized you need a ton more.
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.
So, for years I have used the FolderShare applications a P2P program that can securely sync folders across the internet. It has some limitations but is still worked great. Then, Microsoft purchased and everyone was worried that they were going to kill the program. Luckily they did not kill it– at least not right away. They renamed the stupid thing about 3 maybe 4 times.
(hope I didn’t miss one)
Each time they changed the name of the software you had to reinstall the software which was rather annoying.
Now they removed support for various operating system like Windows XP and some other server based operating system.
I logged into the program and was reviewing the new interface which forces you to use their cloud based storage service for the files that you want to share. Which again, kinda sucks because it ruins the whole p2p aspect of the program. On top of that it appears it did no migrate any of my old folders share were being shared from the last version of sync. This again, also sucks.
One more thing, they bundle the application with a ton of other crap, like messenger, photo gallery, bing bar, writer, and some email client. And even though you uncheck all the boxes that say don’t install this other stuff. It still installs all the crap anyways. [rant] None of this stupid shit has anything to do with why you want this sharing application. Why not just bundle it in a windows update if you want it installed on everyones machine so bad. I already have outlook that I don’t use; why do I need another shitty email client? [/end rant]
It kinda sucks now that I can share documents with my friends that still are on windows XP for whatever reason. Luckily there is other competition out there ready to take it’s place.
I ended up uninstalling the mesh and installed DropBox which appears to mimic many of the features without killing off support for your legacy users.
