How big of a difference between Intel gen 2 and gen 3 (320/510 series)?

post #1 of 15
Thread Starter 
I purchased a 40gb Intel X-25v for $60, I'm thinking about getting another one and setting up in raid 0 to use as a gaming drive.

But then I'm thinking, if I spend potentially over $120 on older gen 2 ssd's, I might as well buy one new 320 series ssd instead. But would there be any sort of increased benefit or noticeable performance difference if I opt for intel 320 series instead of x-25 gen 2 series in raid 0?

In other words, two of these in raid 0

Or one of these

Remember this wouldn't be a boot drive, I already have one for that.

Any thing else I should consider?

Thanks!

The 320s are faster, but probably not worth the hassle for performance alone. The other difference is the 320 series supports hardware level encryption. The 510 is quite a bit faster, it's also SATA 6gb/s. They're also quite a bit more expensive, though.

Keep in mind that by RAIDing your SSDs you lose TRIM.
Why upgrade?

couldn't have put it any better tbh.

The major difference between the X25-M G2 and the 320 is in the firmware and the usage of 25nm NAND Vs. the 34nm NAND. The X25-M G2 did not have GC so degrades quite significantly in RAID. The 320 does however have GC so it basically does not need TRIM.
Keep in mind that the 25nm only is rated for 3000 Write Cycles Vs. 5000 cycles for the 34nm variant which is still being used on the 510.

If you want to run RAID0, I would recommend to ditch your X25-M and go all 320 or all 510. If you have a SATA III interface, go with the 510. I would not recommend raiding the X25-M.

X25-M: 34nm NAND, Intel Controller, no GC, TRIM, SATA II
320: 25nm NAND, Intel Controller, GC, TRIM, SATA II
510: 34nm NAND, Marvell Controller, GC, TRIM , SATA III

Nice answer. Only problem I see with the 320/510 are there low random write speeds, since that is where you want the speed for real word day to day computing. You are not always copying huge files for sequential speed. There it seems the Vertex 3 is king of the roost

Another bonus is that the 320 now comes with 5 year warranty

I'm loving my 320! Its supposed to be a mainstream SSD as opposed to the performance 510, but it is still blazing fast....

Did you come from mechanical drive to SSD. Then it is fast. But as far as benchies go they do lag behind on random reads.

Do you have the 160GB 320?

Sorry not for replying sooner. Masterm: You might want to read actual tests. The IOPS provided in the specs are not exact. I think different manufacturers quote different queue depth as their 4k IOPS and it causes discrepancies. As an OS drive, the typical queue depth you will see will of the order of 1-8 and most of the time 1-4. The Intel drives are not nearly as bad as the specs would suggest.

Sorry perhaps I was not clear with my post the X-25M has slightly better benchmarks than the 320. And not the 320 to the to the 210. Well that is according to what I have

Check this review. The 4k and Iometer are all very close and seem to be a bit behind but all the real life application benchmark have the 320 crush the X25-M for some reason
