It sure does. I'd believe Samsung Magician. In that case the SSD is fine and nothing needs to be done.
@Brian K, would you believe that the culprit is Shadow Defender! When enabled it clobbers my SSD's throughput. The clue: It dawned on me the Samsung Magician benchmark (above) was run without SD, while others were run with SD enabled. HERE ARE COMPARISONS WITH AND WITHOUT SHADOW DEFENDER (all other conditions are the same): ATTO Benchmark with SD enabled. ......... ATTO Benchmark without SD. AS-SSD Benchmark with SD enabled. .................................. AS_SSD Benchmark without SD. Brian, do you think this huge 'SD performance hit' could be due to Intel RST, or do you think it's universal?
Cruise, That is amazing detective work. I'm impressed. I've never been a SD or an Intel RST user so I can't answer your question. I recall (maybe) one of your threads from a few years ago where there was a backup/restore issue with Intel RST and I made a mental note to exclude it from my system. But I thought Intel RST was only to reduce startup time. It isn't Intel Rapid Storage Technology which I do use and is functional. How does your OS "feel" with SD disabled?
I typically use SD to trial an app (or run a benchmark) as I can be assured of no 'leftovers' after a restart. I can't honestly say I've noticed a performance issue (before) with SD enabled, but after this revelation you can bet I'll be much more observant. To answer your question, my notebook seems to be performing well enough. It's just that I never experienced a performance 'wow-factor' after upgrading my original HDD to the Samsung SSD. So maybe AHCI wouldn't make much of a difference?
Your current figures imply AHCI is enabled. Those speeds are great. I've swapped HDs out of laptops and installed SSDs. You should see a significant reduction in boot time and apps should load faster but I wouldn't regard these changes as "wow". Do you still have the old HD with the OS? Maybe a comparison if you have the time. Recently my boot time and apps loading time increased and as it happened gradually I didn't notice the slowing for over a month. It took that long to sink into my brain. Malwarebytes was the culprit. After uninstalling MWB my computer was snappy again. Boot time went from 45 seconds to 15 seconds and apps loaded in a third of the time.
I believe your original 7.9 disk rating (fastest possible in that evaluation) was due to your li'l SSD cache, not the HDD itself. Now you have an SSD which should look the same as the original as far as the 7.9 evaluation is concerned. No HDD alone ever gets that 7.9 reading. As far as AHCI is concerned, I would try your Intel RAID config without a RAID configuration... RAID requires an AHCI queued interface.
It is likely that my original 7.9 rating was due to the 30GB (cache) SSD cache and I have since disabled the RAID configuration (please see posts #1 & #39). Nevertheless, every indication is that AHCI is deactivated and as I told Brian....
