paid 2300USD for this laptop just for this

Does phone Storage count?

No, 8x Seagate 600 Pro enterprise SSDs in a RAID 0
Connor Cooper

Enjoy your shitty access times
Adrian King
lolwut?
Josiah Taylor
Isn't the whole point of RAID0 to have faster transfer speeds and access time?
Wyatt Taylor
SSD's in RAID 0 looks good in benchmarks, almost double the seq read. But the RAID controller, whether software or hardware, will add overhead to the near-instant access times you'd get with a single good SSD

This, fuck and think people use cheap RAID controllers

I'm going to implement my own raid standard and call it RAID K
It's basically mirroring but reads from both disks
So
DRIVE0---------DRIVE1
0-----------------------0
1-----------------------1
1-----------------------1
0-----------------------0
1-----------------------1
1-----------------------1
1-----------------------1
Both drives are mirrored identically, giving you parity, but by reading data from both of the disks using striping, you double the read speed.

Pretty sure RAID 1 doesn't double your read speed mate
Caleb Rodriguez
It always has.

That's for multiple reads accessing the disks at the same time, the type of speed from striped reading is talking can be done with Linux's md software raid with raid1 in far layout for example
Nathaniel Rogers
>I dont understand what a stripe size or block size is
William Sanchez
Pretty sure you just explained RAID1, you can configure it exactly like you explained it...
Levi Roberts
What's there to understand? For sequential single thread read the normal raid 1 (near on the graph) performs twice as slow as raid 1 in far layout
