SSD`s RAID 0 and DCS - Yes or No?

[Falcon_S]

Guys, what do you recommend?

 

Is it worth it?

[GGTharos]

Hi falcon, your SSD Ajay provides such an enormous step up from a regular HDD that using RAID0 is pointless - your risk of losing data of one of the disks fails is greater, and I imagine you'll never actually see a practical performance boost ... Just not worth the money IMHO.

[Falcon_S]

I've read a lot and mostly everyone says it's not worth it. I just wanted to hear the advice from our world, DCS World :) .

 

I agree with you GG...

 

Thanks.

you would be better off with a m.2 drive then raid.

[Johnny_Rico]

not worth it , better with M.2

mine benched close to the one listed above

[Falcon_S]

I agree with you, OldE24 !

 

But, this toy is still too expensive for many of us in this region (Balkan). That is problem :)

stay away from intel-ichr based raid-0 is my absolut best advice !!!!!!!

 

you may do raid-1 and see how often it looses sync after a bsod etc.. with a raid-0 this would have been instant death/data loss.

 

rather get a nvme, that speeds up w/o the risc of raid-0 loosing sync

I used to run dcs on a striped array and it was fast but I then went to an ssd which blew the raid out of the water. One thing I discovered get biggest size possible. Small ssd s under 120Gb are not worth having when they get fuller than about 50%

I was convinced of this, definitely a small capacity SSD should be avoided.

why do I read these posts? Am I going to have to buy an M.2 now?? LOL

Lately I ventured into Crypto Mining and found out, that without a SSD drive, even better NVMe drive, you better dont even try syncing an Ethereum Wallet with full Blockchain. The constant r/w on the drive is beyond what a HDD can do, you will just hardly ever sync and stay synced. This was new to me, a mandatory SSD for a "wallet". Since then I value my NVMe very high, you can clearly see the advantage over Sata-SSD once you open more than 1 wallet and that things starts to scream like an eagle. I/O is everything

If you've got a new enough motherboard you can give Intel Optane a try, it uses a specialized small but super fast M2 drive for caching your most recently used files. It's a lot cheaper than a second entire drive, and if it dies the system should keep chugging instead of losing everything the way a RAID 0 would. You should still keep backups of course, there are very cheap cloud backup services available now.

Weird, I figured that the main bottleneck with syncing a full copy of a blockchain would be your internet bandwidth, not your hard drive bandwidth.

It depends on the wallet, BTC core client will suck up all your bandwidth when you sync from scratch for days.

 

ETH has such a fast pace, that it's damn hard to sync with a HDD and keep synced. Their specific forum says "dont do HDD, it's a SSD thing"

 

Luckily , ETH Blockchain is only <50GB, BTC BC is going close to 200GB now, that fills a complete 950evo-nvme-250GB...ehhhhh NO ! not now. I moved that wallet to a HDD and it works, just dont multi-task that drive.

 

I never thought that running like 5 full-core wallets would tilt a PC,...well, it can !

 

 

Are you doing this new fancy Timetravel and Tribus algos ? Man, they rock hard, money wise ;)

 

My buddies all venture into mining, LOL, we are competing vs. each other but share the knowlwdge we gain as well.

 

 

BTW, the newest NV driver from yesterday kills CCminer, stay away, I lost 1h mining due to that BS.

Interesting. I just built a new rig with a 1080ti, what's a good thing to mine with that? I was mining LTC and Doge a few years ago with R9 290s but the scrypt coins got killed by ASICs.

I have two 960EVO's in RAID 0 with DCS on the installation. I have definitely seen a performance increase. Prior installation was M.2 NVME single drive. However, as they all stated above, its very expensive to do with a lot of risk should one drive fail. One NVME will provide amazing performance.

Since 1 NVMe already tilts your PCH, both use PCIe-4x. there is not really any lane left for a 2nd NVMe to go to full speed. It will work, but 2 x PCI-4x devices will need to run over 1 x PCIe-4x bridge. This is less than optimal, as it flodds the PCH that much thzat I would fear other devices being blocked if your NVMe-Array spools up for the party ;)

 

Your Raid-0 should read soemwhere between 5.5-7 GB/sec and write at roughly 2.5-3GB/sec.

 

There is no way the Z370-PCH will do that, you will not get back out with Z370 what it could actually do with a proper board.

They are also making optane drives large enough to use as primary storage, but require a regular PCI slot: https://www.anandtech.com/show/11953/the-intel-optane-ssd-900p-review
