LTT Forums SSD Performance Database

[T.Vengeance]

So I recently got the idea of having an SSD database here since buying an SSD today (while much cheaper), many still consider it an investment.

 

So here's what you guys do:

 

1. Download ATTO here http://www.techpowerup.com/downloads/1749/atto-disk-benchmark-v2-46/
2. Post a screenshot of your benchmark in this thread.
3. Post your 4k read/writes and maximum read/writes in this google docs https://docs.google.com/forms/d/1dkj4MtWLogf2ExLSFLEAqWDiZadajgWY3wMoY_sFvgI/viewform?usp=send_form and link your post with the benchmarks screenshot there.

 

Here's the results: https://docs.google.com/spreadsheets/d/1aCj2GKakRlTlx6HxAP0vzx5uRhHA8xiv4G60ngXrl5c/edit?usp=sharing

I'll let you add me because I'm lazy. I also don't get this shit, can somebody tell me which one of these is 4k? or do you mean just "4000" value.

It's the write speeds for a 4.0 bar on the top left. TBH that's the great thing about community submissions. It's everyone doing a small part instead of the OP/mods doing a whole bunch. So while yeah you're only one submission and I could enter you in, I'm not gonna start if it's going to be a pattern for everyone who's lazy.

Both identical model drives, different file systems.  The OS drive has Approx 41% free space.  I'll post their average in the 4k doc.

Though, I don't think you'll want my stats since they're on an older mobo.

Samsung 840 EVO 1TB

OS drive in laptop with 24GB RAM, RAPID enabled

Overprovisioning of 10% [Default], 931GB usable

S.M.A.R.T. reported +~25GB Host writes on each of the benchmark runs (I did 3 runs just to be sure. The other looked very similar)

 

This probably shouldn't count in the database but I thought it would be interesting to share. Can someone explain what's happening with those larger transfer sizes and the write amplification indicated by S.M.A.R.T. (I doubt the benchmark intended to write ~25GB)?

 

As a suggestion, could you add a field in your database for comments about the system config? Perhaps change the "Do you RAID?" to "SATA2/SATA3/mSATA/SAS/PCIE2/3(number of lanes)/RAID controller? ... e.t.c". That would help explain odd benchmark results (e.g. ^ on SATA2?). Also having results in MB/s I think would be easier to read and compare (too many numbers, the last few are within margin of error anyway), though I guess it's not too hard to convert mentally.

o0, nice topic.

 

Will participate when I'm home (unless I forget)

Are these read/writes good?
