Burn, baby...diskless inferno...
Cloning SSDs for Dell blades. My low-tech setup:
Understeer: You will hit the wall with the front end.
Oversteer: You will hit the wall with the rear end.
Horsepower: How hard you will hit the wall.
Torque: How far you will move the wall.
Gone hunting with Alec Baldwin and Dick Cheney. Back soon.

Re: Burn, baby...diskless inferno...
We run a bunch of high-density servers (12 blade computers in each enclosure) to host one of our products. Instead of installing and configuring the operating system and all of the server configuration a couple dozen times, I build a master image for one computer and clone the drive onto blank drives so we wind up a bunch of identically-configured machines.
There are software tools to do this, but I really like hardware cloning. I have another unit at the office that will clone three new drives simultaneously, but I only need to bust out 5 today, and it only takes about 10 minutes for each clone...

Re: Burn, baby...diskless inferno...
I feel like each one of these pictures is a puzzle. Tell us about Thermodynamics! (Actually, looks like you haven't cracked it yet...)
How often do you have to replace these Samsung drives on a Dell Blade? I have my editors & animators working together off of Qnap 8-bay diskless NAS servers. I'd say we replace a disk or two every year or two. Though, those drives see some serious writing, re-writing, and re-re writing at least 40-50 hours a week. Our "Art Server" is an array of 3x Promise Pegasus 8-bay servers (we do lotsa art ) and those drives seem to fail more often than on the Qnaps, even though the Qnaps are tuned for speed.

Re: Burn, baby...diskless inferno...
The thermodynamics textbook is a riser for my Macbook when I'm 3D printing crap - but I did bust it out to win an Internet argument several weeks ago (the comments section for “perpetual motion machine” videos is an incredible resource for finding morons). Mrs. S's great-uncle was an uber-nerd, and I wound up inheriting a few of his reference books (like a really cool handbook on gear train design).
The Samsung drives are oversized and the blades don't do a lot of disk i/o, so they tend to last at least a couple of years. I use a pair of 1TB 860 Pros as a RAID-configured read/write cache in each of our production NAS units; they last less than a year in that application.
We're in the process of migrating from the NAS units to a distributed filesystem I've been boring Gnat about for the past year. The Ceph cluster outperforms our Synology NAS units by 50-80x (not %!). Ceph is well-optimized for the way our application uses data. We wind up with a lot of duplicate files, which is typically really slow for NAS units. Duplicates in Ceph are metadata-only operations since there are already redundant copies of the file throughout the cluster, which makes file "duplication" almost instant.
