I will second Sager, I have been very pleased with my Sager NP8255-S (aka Clevo P157SM). I is going into its 2nd year now. I ended up choosing the Sager because:
1. strong i7 cpu
2. up to 32gb ram
3. supports four hard drives
Actually "four hard drives" for this model means 2 x 2.5" and 2 x m2 slots. Which is huge, compared to the alleged mainstream performance workstations like Dell's Precision line or HP's z-books or Lenovo's W-series.
I'm running 3 x 400gb ssds in a raid 0 and I find that disk-intensive workloads are pleasingly
I am getting the following in PassMark's Performance Test 8.0:
overall disk score: 5,558
seq read: 715 MB/sec
seq write: 523 MB/sec
random rw: 300 MB/sec
(just for the record, I run regular backups because because of the potential fragility of raid-0).
Why not a 4-drive raid? I figured I'd save a 2.5" slot for a multi-terabyte disk some day for on-board archives once I fill up the ssd's. (And I still have the optical bay to drop a caddy in if I need more storage).
Until 8x pcie ssd devices are available in laptops, raiding SATA together seems like the best way to boost lugable disk performance.
It loosk like the NP9752-S
is the current model of this machine.
Now... if if you're looking for insane
power in a laptop form factor, take a look at Eurocom's Panther
If you really need crazy CPU cycles, this seems like a good choice:
PassMark for xeon E5-2687W v2
Here are the specs; I didn't go with the Panther because the cost-curve didn't work for me (money actually is an object in my case).
