SSD Throttling Speed?! Help Please!!!

[PeterHanz]

Tom’s forums have answered years worth of my computer problems, but now, it seems a ton of the current problems I’m having are from 2011 or even older which make it very outdated. I’m going to get right to it:

All my SSD’s are throttled at the 400/395 read/write speeds. This is no where close to the speeds I should be getting for any of my SSD’s. Current SSD’s: Samsung 850 EVO 500GB | PNY CS2211 480 GB.

Attached are the speed tests, with the appropriate boxes to label the ssd’s. Another thing- if it were the port, I know where they should be connected (SATA 3). I have updated all the SATA drivers available for my motherboard, and I’ve also turned on Rapid Mode as well as put on the optimization for maximum performance on my Samsung drive and the numbers shot through the roof (so I’m pretty sure it’s not a defective SATA Port, or a defective SSD- what would be the chances of having 2 different companies with two different SSD’s throttling unless I allocate RAM with the Samsung magician program, and then a 3rd part program for my PNY? Very unlikely).

I hope I don’t come off ignorant or pissy, but I’m very upset that I get pretty sick SSD drives, and then for them to be under 100 mb/s advertised & capable speeds. Maybe it is my motherboard? Maybe it’s something else. Please, any and all help will be greatly appreciated! I do tons of work, and my career is based on this machine, so the better the speeds, the quicker I can do my tasks.

Here are all the specs I currently have (I’m going to list everything as my experiences have sent me through the biggest problems being really wacky solutions of parts I thought were not important):

MOTHERBOARD: ASUS Maximus V Extreme LGA 1155 Intel Z77 Extended ATX Intel Motherboard

CPU: Intel Core i7 3770K Ivy Bridge OC’d to 4.6GHZ

RAM: (4 x 8GB) G.Skill Trident X Series 8GB 240-Pin DDR3 SDRAM 2400MHZ

SSD #1 (OS and software is on this drive): Samsung 850 Evo 500GB

SSD #2 (Files and Storage on this drive): PNY CS2211 480GB

HDD: Western Digital Black WD2002FAEX 2TB 7200RPM 64MB Cache SATA 6.0Gb/s

COOLER: Corsair Hydro Series H100i Extreme Performance Water/Liquid CPU Cooler

CASE: Rosewill THOR V2-W Gaming ATX Full Tower Computer Case, White Edition

POWER SUPPLY: FirePower ZX Series 1250 W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX1250W

1) that test image shows you have an 840 evo, not an 850 evo.
2) ssd drives are fastest when they are new. speed does degrade over time. those speed tests are very likely correct if they were purchased in 2011. they are most likely at the end of their lifespan.
3) the more full an ssd is the lower its performance will be, in short.
4) have you tried a different benchmark program?
use samsung magician to set the best performance settings for that drive and use their benchmark. then post results.

Hey there, Peter.

What's the SATA mode of your SATA controller, is it AHCI or IDE? It should be AHCI, you should also check if you have TRIM enabled. This is an OS (operating system) function, which deletes residual data from the memory block of your SSD so that you can use the drive at its optimum performance throughout its entire life. It really important that you have TRIM enabled. Also, do you have any space left for over-provisioning (OP). This is space left for reorganizing the data on your SSD (which is done automatically as well) and you can't use that space for the partitions of the SSD. Most manufacturers recommend 5-10% of the drive's capacity to be left for OP.

It's normal for you to have such boost performance wise when you have enabled Rapid mode as this utilizes some of your RAMs capacity and it's used to speed up things overall.

Check out this article with useful tips for SSD users: https://www.maketecheasier.com/12-things-you-must-do-when-running-a-solid-state-drive-in-windows-7/. Even though it's for Windows 7, those recommendations are also viable for the newer versions of Windows as well.

Hope that helps.
