Raid 0 vs Single SSD

[Hipstair]

I'm looking at upgrading my storage solution for my desktop. My uses have changed since I originally built it, and SSDs have come down in price since then, so I figured it might be time to upgrade. I currently have an Intel 240gb 540 series ssd, which I plan on using for cache of my 2tb seagate HDD. I'm looking at Adata's SP550 as I used it in a build for a friend recently, and I've been puzzling over getting the 960 GB option or going raid 0 with 2 480 GB drives. Price difference is only $20 ($220 and $240, respectively). Thanks in advance!

There will probably be a difference in speed, as data is being written to two drives simultaneously compared to one drive. However, this also increase the likely hood of data loss as if one drive fails, you cant just pull data off the other drive. All data will be lost.

Don't raid 0 SSD  unless you are going to back more than just weekly.

I'm using the 2tb drive as a backup, so I don't think data loss should be much of problem

well first of all, you dont need the speed of two SSDs ins raid

you will get no improvement in anything, unless youre doing content creation as a daily job which I doubt

 

second, do not do software raid unless you want to spend a lot of time setting things up, losing all your data, then having to set things up all over again

 

third, dont use a SSD for cache

it will just increase the latency when you go to open a file and you only get a speed benefit when you open something multiple times, because it has to decide when to move it from the HDD to the SSD depending on how often you use that data

it also causes a ton of writes to the SSD unnecessarily decreasing its lifespan

i think its much more efficient if you just use the SSD as an independent drive and put the data you want on it yourself, so you get to decide what goes faster, not some software

 

fourth, get a larger SSD instead of two smaller ones

 

fifth, get an 850evo

It will just make your computer take longer to boot since the RAID controller has to initialize. There's no tangible benefit to RAID 0 SSDs unless you're transferring huge files all the time, and whatever device you're transferring to is also just as fast as your RAID 0 array.
