SSD RAID 0 or 2 Seperate Drives

[LongBigBronzeElephantFish]

I've just gotten 2 Intel 730 480GB SSD to upgrade my current Intel 520 240GB SSD.
Would it be better to run both drives in RAID 0 or 2 separate drives?
Like OS in one drive, applications, games, data, scratch disk etc... in the other drive.
Or just RAID them and get one big 1TB drive?

I'm a game developer/software developer/web developer/gamer.

For sata connection, you don't benefit from raid 0 as speed is bottleneck by sata3 600mb/s limit.

SATA 3 600MB/s limit only applies to single drives.
Means each drive in the RAID array can have a maximum of 600MB/s speed.

say i have a 2 year old WD blue 1tb

if i get a brandnew WD blue 1tb will it work safely for raid 0?

U sure ur mb is correct??

Anyway for ts. Have to dig out my old post lol since you don't do the digging.

Raid 1, 0, 10

if your SSD read/ write speed is 200MB/sec
2x RAID 0 , becomes 200MB/sec x 2 = 400MB/sec

The downside of raid0 is that one disk fail everything gone.

I used to run raid0 2x256 SSD for boot drive. Now I am using a single 500gb SSD. The raid0 setup runs faster in booting up.

If you are running RAID 0 make sure you have backup for your data. I am running 4 x 256GB RAID 0 now. But I have another 256GB used as backup.

Intel 730 is specifically design for raid 0 performance.

Tweaktown did a review on both single drive and raid 0 drives for intel 730 and samsung 850 pro.

On single stepup 850 beat intel 730 hand down, but when they are on a raid setup, the opposite happen. intel 730 raid 0 thrash 850 pro raid. . Do note that samsung drive alr see significant improvement with raid but was nowhere close to intel 730 raid.


Tt rate it as a raid champion. I guess the answer is clear for u alr.

Intel did alot of advertisment with their specifically fine tune raid setup for 730

Intel 730 suffer badly in Benchmark as mentioned by TT, but in day to day real life stimulation usage it actually triump the 850 Pro RAID 0.... It is used to compared even to Intel P3700 NVMe SSD.

Read the full review to understand what is going on.

We consider steady state bandwidth (the blue bar) to be our test that carries the most weight in ranking a drive/array's performance. The reason we consider steady state performance more important than TRIM is that when you are running a heavy-duty workload, TRIM will not be occurring while that workload is being executed. TRIM performance (the orange and red bars) is what we consider the second most important aspect when ranking a drive/array's performance. Trace based consistency testing is where true high performing SSDs are separated from the rest of the pack.

Even though our 850 Pro array was able to dominate our synthetic testing by easily winning every test, quite the opposite occurred when we moved to real-world simulations. In this, our most important test, our 850 Pro array was unable to keep pace with our top arrays.

We have seen this before, so it's not really much of a surprise. Granted, this result is better than all but one consumer based PCIe SSD (Samsung's XP941 m.2 drive) running on the AHCI protocol, but in the end, it's somewhat disappointing. The 850 Pro in RAID 0 does not like the incompressible mixed random workloads that this testing simulates, and that's our measure of true performance.

We were hoping to see a new RAID champion crowned today, but that's just not in the cards for the 850 Pro.

Here is the quote from TT

But PCMark is not a real life simulation, just a benchmark. What makes you think 730 is not optimised for PCMark?

Furthermore, TT is using Z87 mobo...... They should use a RAID controller card to bypass the DMI bottleneck.

That is true but still the Z87 is use on both the pro and 730 hence it is considered same relative performance...


I cant really tell since I dont own a raid 0 of either 850 or 730, but I have seen afew TT review where they always used it to compare against 730 Raid 0 config because they claim it as RAID champion.

Anyway other review have also indicate massive performance boost once 730 is paired together in RAID 0, with performance jump >60%.

I am hoping they could perform more realistic tests like loading times, copy times etc....... Eg. how long it takes to load windows, load games etc.....

I don't know about benchmarks but sequential performance does affect copying large files.

 

[Gattberserk]

Either way no say we shld buy a pair of 730 for raid, but since TS has already got 2, you might as well as raid it...



Unless of cos if data integrity is very impt.

I need to go dig up those review I saw with raid 0 730s...

 

[Piezoq]

Note for an OS drive there are not many occasions where large files are opened sequentially. Speedup is most readily observed in such situations.

Let me illustrate. I recently swapped a Samsung 840 with an old Intel X25V on a Haswell laptop. The Samsung has 2x the throughput and capacity. Bootup was a little slower, and sometimes I felt the machine was a little laggy compared to before. But I wasn't turned off by the experience and if I were honest, I probably won't be able to tell for sure which SSD was installed in a blind test.

Usage I can think of where a Raid array makes a big difference is in video/graphics/3d production and high-end gaming.

 

[weap0nx]

Just do a poll of how many users still Raiding their SSD and you'll come to the realisation that it's not worth it. It made a big diff for first gen SSD on first gen SATA, now you're just making a refined product complicated with no practical gain to yourself

One SSD vs Two in Raid 0

base on this article seems like there isn't much real world performance gain to go raid 0, plus the risk of data loss if one ssd fails.
