Samsung Magician 4.5 RAPID Mode – Evaluated With Demonstrated Speed Increase

TSSDR TEST BENCH AND PROTOCOL

For today’s testing we will be using our current test system that has been optimized with our SSD Optimization Guide. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch.  We even provide links to most of the benchmarks used in the report.

BENCHMARK SOFTWARE

To test RAPID the software we will be using for today’s analysis include Samsung Magician, BootTimer, PassMark AppTimer, and PCMark 8. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.

SAMSUNG MAGICIAN 4.5

To start off our testing we chose to use Samsung Magician’s built in benchmarking tool to compare the performance of the drives. The darker blue bars are the results before RAPID was enabled on the system. The light blue bars are the results after RAPID was enabled.

Samsung 850 EVO 1TB RAPID Before & AfterBased on this synthetic test, performance seems to be night and day when comparing the drive with synthetic tests. Random read IOPS shot up to over 2x and write IOPS increased by 50%. Sequential reads and writes improved to 10-11x. From these results, impressive is an understatement. Now, let’s move forward to startup and application load times.

STARTUP WITH BOOTTIMER

In order to test the startup time we used a simple program called BootTimer. BootTimer gave us consistent results on how long each system boot took over the course of testing.

RAPID on vs off Start up time

Numbers don’t lie. Over the course of 5 system reboots, enabling RAPID results in slower boot time…while only slightly, it does have a detrimental effect.

APPLICATION LOAD TIMES WITH PASSMARK APPTIMER

For testing application load times we used PassMark AppTimer. AppTimer can measure the time it takes to open an application and automatically run multiple iterations of opening the application one after another. It then creates a log file with the results. Each application was launched for 5 iterations. Below are the results from launching popular software applications.

RAPID Mode off application load time RAPID Mode on application load time

 

 

 

Based on these results it seems like Window’s default caching system already caches the programs into the cache after they are first launched. There is essentially no difference in application load time whether RAPID mode is enabled or not. So, we then rebooted the system and tested again, RAPID mode is supposed to retain the previously cached files after the system is rebooted, unlike the default Windows behavior which is to flush them.

Rapid Mode Average app load time

We also noted when testing that RAPID will work 45 seconds after the system is booted and waited thus to begin testing again. This delay for RAPID mode can be seen in the memory tab of the task manager under Non-paged pool. Without RAPID the value is around 125MB in our system. Once RAPID begins working, the value changes to 1.3GB.

After testing multiple times, the results above bring us to the conclusion that RAPID does not in fact speed up application load times. Windows already does a good job at caching these files itself. However, one thing to notes is that while Windows already caches program files, Samsung’s algorithm is supposed to do it more aggressively to frequently used files. Let’s put that to the test.

RAPID Mode off Document load time RAPID Mode on Document load time

 

For this we re-ran the iterations over 3 system reboots to ensure RAPID would have enough time to cache the files. The final reboot’s results are what are displayed. We can see that RAPID was able to load the Photoshop file initially after reboot a little faster than when RAPID is disabled, however after the first load time, it actually takes longer for consecutive load times.

RAPID Mode average Document load time

Overall, the averages were practically the same.  We are not seeing this claimed “almost 1.8x performance gains at Windows start up and application loading.” This is a bit of a disappointment as that is what they are essentially marketing RAPID to do. Startup times are slower and application load times were unaffected. Now, there is still more testing left, hopefully RAM caching will help in our next segment.  Let’s move on to running light and heavy workloads to see if it really does increase performance in real world tasks.

Took 1.5GB I guess out of my 8GB pc. RAPID is really nice but I think I can live without it too. All that matters is that one has to move from a HDD to SSD for atleast the boot drive. Have the 850 Pro myself. Team RED we are 🙂

Hi Sean, what are your thoughts on RAID 0 Mode? I have 2 Samsung 120GB 850 EVOs. Should i leave them separate, first one being the system disk with RAPID enabled and second one for programs or should I RAID 0 them? I don’t care for the safety of the data, just speed. I do some prepress design and gaming. When in RAID 0 mode, Samsung Magician doesn’t seem to recognize them. Thanks for your help.

It is my understanding that the EVOs were never meant to be used in RAID configurations, which is probaby why the MAgician software is not recognizing them. For that reason, and better reliability, I chose to stick with the 840 Pro and 850 PROs.

owner of a 840 Pro, if you raid them you can’t see them in magician and trim is always disabled(stripe 0,1 etc) <<—no matter what model you have, same applies to 850 PRO

Trim has been supported for ssd raid arrays since 7 series motherboards (z77).. download the intel raid driver for your os and your golden. (driver can only be installed once in raid mode)

???????????? ?.
Guest
???????????? ?.

NOT in raid 0,1,5 ..ONLY raid mode but as single disks (TRIM is useless if you use RAID 0(stripe), or raid 1(mirror))

Do your homework and come back 😉

P.S. IDE, AHCI, RAID modes but nowdays only AHCI and RAID modes available

This
article clearly states that trim is indeed supported for raid 0 arrays
on 7 series motherboards. Ive already done my “homework” sir.

Well that’s great, in the past the only thing intel did was to manage single drives in “raid mode” if they manage raid0 in 2 drives then kuddos to intel. Too bad you need specific motherboards to do that..

For me, I would set up which ever way is easiest for you. I would personally set them up in RAID 0 and store both the OS and programs on the same volume. Just make sure you do routine backups and you should be golden. Samsung Magician does not detect the drives as you have noticed, it is normal. I personally don’t bother with installing Magician in my own system.

you cant use RAPID in RAID…tried it

It might work if you use Windows ‘spanned volume’ ? So that’s not RAID, but essentially the same as RAID 0 (combining two disks without redundancy).

Gary Noah

Spanned Volume is not the same as RAID 0. Spanning just writes to one drive at a time. Raid 0 uses two or more drives as one, so reads and writes are faster. A good two drive RAID 0 setup should increase throughput by 60%. So 540 transfer with one becomes 864 with two in RAID 0. A real good setup should almost double reads, writes, and transfer speeds. Spanning will not increase speeds.

my friend has a gaming pc with 2 1tb ssds in raid0 he said its the fastest storage he has seen (and he is a professional it technician). but it all depends on the type of raid controller. if its virtual raid I don’t think you should do it unless you really want all your space to be unified. but if its hardware raid you would probably get a faster write and read times.

just my opinion

Unless you are in an enterprise scenario. The raid 0 doesn’t affect real life performance, as most the time the SSD’s bandwidth isn’t your bottleneck. I have done a raid 0 with 850 pros and looked into upgrading my 850 pro to a 950 pro. Benchmark wise yeah the speed performance is way higher. But when i comes to boot time and application speed there is very little difference. Plus with raid 0 your data isn’t safe, and with Rapid Mode’s low latency, it becomes more of a want then a should. shabammm

Hi, so if the RAPID tech is ON, then I can get some performance gain in PC games for example or not really? 🙂 (I mean if these games are installed to this SSD & also this games are very often loading textures & other datas from this SSD where the RAPID tech is ON.)

Dan Kaschel

Definitely not if you’re using a gaming computer. Textures are loaded into VRAM (memory on the video card itself) which is much faster than system RAM or the SSD.

Even machines without a video card will cache as much texture data as possible in System RAM.

I have 28 GB RAM on a HP Envy 700 430 qe. When I use the rapid drive, I get scores of 3700+ MB Read and 2400+ MB Write. Is that real? The computer is very fast with the 850 Pro 512.

In RAPID mode you are basically using a RAM drive that gets synchronized to disk as quickly as possible. Your RAM is very much faster than the SSD. But you risk losing the data in RAM if your computer loses power.

That’s what a laptop battery is for. To have no interruption when mains power is lost. I have a business class HP Workstation with two batteries on it for double security. On the workstation there is a lot going on to insure data loss is avoided. It is the perfect environment for the RAPID Mode, especially with 32GB RAM installed and a second SSD in the Optical Drive Bay. The way I work on a laptop makes data loss minimal too. Any data I lose will likely be progress since the last save. I am contantly saving my progress and… Read more »

I have only 4GB RAM (DDR2) on a 6+ years old Lenovo Laptop (Core2Duo). The SSD is connected via SATA2 port. Even I got 1800 MB/s read & 1300 MB/s write speed, when rapid mode is enabled. But practically there was no other benefit other than the benchmark results (Other benchmarking tool revealed similar result too). So, finally, I disabled it as it took too much RAM space from my 4GB RAM.

You don’t really ‘lose’ that RAM, it’s actually a small RAM disk speeding along your computer. Even one with a SATA-1 MB would benefit, that is, it’s it’s an AHCI enabled one. Samsung tends to be picky, Intel SSD’s less so. The RAPID app only uses 20-25% of your available RAM, depending on if it’s the 840 or 850 series, and in real world testing, I’ve found the RAPID app help SATA-2 computers more so than SATA-3, which usually has other built in features to boost performance. With 4GB, at the most, RAPID will use 1GB RAM, and take my… Read more »

RAPID mode causes crashes–Windows 7,SP1, Samsung 850EVO. I enabled RAPID mode two months ago and ever since I have seen weird hangs and crashes every three or four days. Disabled RAPID two weeks ago and have seen no crashes since.
