Just got a second 128GB 840 pro and put them in RAID 0 for my system disk. Restored from backup. Here is performance (obviously not RAPID).
Also, some people suggest that using RAID slows your boot time due to initialization of the array. This did not change when I put these in RAID0. I also have two 1TB blue drives in rad0. My reboot time (full reboot cycle measured by reastart_time.vbs) is still 16 seconds.
here is old and new for my rig.
massive bench improvement from 830 to 850 pro, real world improvement is not so big, I mainly brought the 850 pro as I wanted a bigger ssd and to give my 2nd rig (testing win10) a ssd.
I don't think this drive is performing as well as I thought it would - Samsung 850 Pro or at least not what it claimed in the ad and now on the box.
It is quick to boot but again I am using my new Asus G750JM which is a bit of a screamer but this was not what I expected.
John, there is nothing wrong with those numbers. The Sequential could be a little higher, but not much. You are still at the limit of Sata III. The 'Practical" limit is around 450-525 for Sata III. It can't go any higher than that. That's why you are seeing some Sata express starting to come out that run off of PCIe lanes which are faster. They have reached the limit of sata III. Plus the fact that you will probably never actually use the Sequential number. Most OS drives use the 4KB read speed and access times about 95% of the time. Those are the only numbers that really matter, and they are pretty good.
Ok Steve I know you have told me that before but it has a hard job sinking in. I was comparing the figures to GeneO's and thought heck what am I doing wrong, plus this is the new laptop I said I was getting. It runs lie a cat with it's tail on fire but the 840 EVO I had in it prior to this 850 which promised all sorts of lightning speeds etc
Oh by the way the new lappy is just the bees knees except for some slight keyboard changes I am having to get used to.
There is suppose to be a slight speed increase with the 850 Pro, but probably not a nickels worth to be honest. The 850 Pro, however, will last you until you get tired of it........it has a ridiculous life cycle because of the type of Nand they use in it. Also, the other Samsung drive, the 840 Evo......are you running the Microsoft SATA controller on it as well? You can tell when you open it in AS SSD as it says "msahci" in the top left-hand corner of the program.
I don't know mate as I think I am going to have to put back the original drive (a 5400rpm spinner) with 8.1 on it because the 7 drivers for that machine require the BIOS to be updated - and guess what that has to be done through a USB stickand yes you have it right the USB ports do not work except for the mouse and charging because the drivers cannot be updated - so even if I were to try that BIOS update I can't.
So after a very frustrating day having to reinstall this main machine the weekend is not going that good and the least of my concerns are the SSD's of which I have a drawer full now.
Sorry about the rant but I think Asus have got this one very wrong.
I wouldn't buy that drive because you think it's going last longer , pretty much any top notch drive you buy today will typically last far longer than you are likely to want to keep it .
The ten year warranty is just a sales gimmick , how many PC enthusiast do you think will stay with the same drive that long even if they could ?
I don't even know anyone who would stick with the same computer that long lol.
Drives outlast computers. I have SSDs I've had in 3 or 4 computers and they still run just fine. I have 2 ND Generation SSDs that I still use and they work pretty well. So, sure a 10 year warranty does mean something to many people, like me. Plus, I think it is refreshing to see a company actually stand behind it's products.
