Raid 0, 1GB per second read and writes

[denniS_redbeast]

How many 850 EVO's would i need in raid to have 1 gigabyte (not gigabit (I know that two are enough for 1 gigabit)) read and write speeds???

is Linus's solution with 8 drives the only way????

I have 2 raid in my laptop, it gets about 800 write 950 read. Megabytes per second.

Why do you need 1GB speed? Not sure how many drives you need but I'm sure you need a lot.

[anders_b]

proberly only 2 becuse 1 is 540 megabyte per seconond

Just get intels new ssd. multi gig r/w

According to various RAID 0 SSD benchmarks, 2x RAID 0 SSD's (Including Samsung 850 EVO) will achieve 800-900 MB/s reads and writes (Sequential of course).

 

If you want sustained 1 GB/s performance, I would sugged 4x RAID 0 SSD's, but 3x is probably sufficient under most circumstances to keep you at or around 1 GB/s.

Just adding more disks in to the mix might not help, you need to have a raid controller that can handle the speed and has a fast enough link to the rest of the system. Also if you really need that high speed you should really look in to getting a NVMe solution.

the 2 ssd's in my laptop get near gigabyte per second reads and writes. The on board intel controller dosent really have any problems with only 2 drives, but the more you add the less you will gain, sort of scaling with multiple graphics cards...

That's a good point. I had assumed the OP would consider this, but it's best to state it outright.

 

@denniS_redbeast The SATA controller may bottleneck, so to sustain 1 GB/s you'll likely want to use a dedicated PCIe RAID card for maximum performance. Especially if you're going to use more than 2x SSD's.

Make sure you back that thank up, RAID 0 isn't very safe if one of your drives fails you'll lose like all of your data.
