Raid 0 vs ssd question

Which has faster reads, wd6400aaks in raid 0 or Kingston SSDNow V-Series SNV125-S2BD/64GB? Which one will be faster in a year? 2 years? Does anybody know if trim will become available on the kingston drive in the future?

here is the link to the kingston drive: http://www.newegg.com/Product/Produc...82E16820139006

here is the wd6400aaks: http://www.newegg.com/Product/Produc...Tpk=wd6400aaks

fyi: I, um, slightly miscalculated and actually have an extra seagate 500gb disk lying around. So, I now have 2 x wd6400aaks disks. I plan to either go ssd and raid 1 with the spindle drives or go raid 0 with the spindle drives and wait for the gen 3 drives next year.

Apples and oranges. SSDs are about access time more than throughput, though throughput is quite good. "Faster" depends on what you are wanting out of the drive.

You are comparing a 64GB drive to basically a 1.2TB logical drive. Do you need more than 64GB?
 
RAID-0 anything mechanical does not compare to any decent SSD.

It might get some higher benchmark numbers, sure, but in real world use, it's going to be far behind, as access times & read speeds are extremely nice w/ SSDs.

Write speeds for large files will be much faster with a RAID-0 setup than any Intel-based SSD, but i don't see why anyone would regularly be copying large files onto their OS drive.

IMO, if you have the money for an SSD, get it.
I can't recommend Intel/Indilinx-based SSDs enough to people.

Edit: that Kingston you linked to isn't the Intel-based one is it?
Don't get an SSD unless it's one of the Intel, one of the Kingston Intels, or Indilinx.
Samsung if you can get a great deal & don't mind poorer performance for some stuff

So just as a thought... moving from a decent Raid 5 to SSD's in my main system... the differences were noticible because the Raid 5 setup was faster at some things. On the other hand, 2x 7200rpm consumer drive in raid 0 on an onboard controller is a bit different than an 8x 15k rpm 2.5" drive Raid 5 with an IOP348 based controller (since even that raid 5 setup would yield 4-5x the sequential reads of the OP's proposed setup.)

All that being said. I'm 100% on the all spindles in servers, all SSD's in PC's that I physically sit at. No vibration, little heat, no noise, and great performance (assuming you get Intel/Indilinx/new Samsung controller).
 
I don't know if that kingston drive is intel-based or not. I read anand's article about ssd's the other day so went looking for the 40gb kingston drive that he mentioned. That drive was sold out at newegg but the 64gb drive was there.

Based upon nothing more than intel's odd drive sizes I would guess that it is NOT intel. I'll do some more research and report back here. If any of you guys find out please post as well.



edit: by the way, WHY should you only get intel or indilinx based ssd's? Do the others have horrible failure rates/terrible performance/kill small animals when operated/etc?

intel/indilinx controllers are the only good ones. samsung controllers are slower.

also intel/indilinx now have TRIM capable firmware. not sure about samsung
 
I know all about trim. However, the kingston intel-based controllers are not trim-capable (at least not yet). the specific 64gb kingston drive that I am considering shows to have the same read/write speeds as the 40 gb intel-based units (100 read/80 write), though I that is just the newegg posted stats.


ok, here's something weird. newegg has two intel x25 m drives, one is just x25m, one is the x25 m mainstream. both have the same posted specs. the mainstream unit is $45 cheaper. WTF?????

it is intel, but severed: half of chips and channels and no TRIM. so it is low-end SSD that has read/write performance lower than faster 7200 rpm drives, and has no latency unlike them
 
nm, I just bought the intel 80 gb for $215 fs.

of course, now it appears that I won't be able to raid 1 my two spindle drives, at least for now. fortunately, I don't typically use much of my drives and what I have I can temporarily dump onto the 1tb external hard drive when intel pulls their heads out of their asses and figures out how to enable raid AND trim at the same time.
