Guys, I am having issues here with the samsung evo 840 120 GB SSD. First of all, updating the firmware didn't help, I used the performance restoration and things are the same.

Hardware is core i7 4770, gigabyte h97m-d3h, 8 GB 1600 MHZ RAM, plus seasonic 520w, r7 265 video Card and 3 old sata HDDs. 2 750 GB samsung hd753lj and one Seagate 300 GB.

One thing that happened is the probable dying of one of the samsung, it ceased to be recognized by the bios and system after that. Drive still plugged, will be removed later.

Using Windows 8.1 64 bit. Boot takes at least a minute, very slow. Benchmarks say reading is 400, 450 MB/S and writing 200. Some people had over 500 in the benchmark. HD tune says ssd is ok. I also disabled some things to increase performance. Nothing.

It should be noted I already had Windows installed in this drive. Then I got a vírus and decided to format it. Used diskpart to clean the disk while booting with Windows install disk. One more thing is that I could not simply format any partition using Windows 8 install disk. It kept saying gpt whatever. Diskpart worked. The first install created 3 partititions.

I believe there's some secret way of installing Windows to improve boot time and the speed of this drive in benchmarks, but I have no clue what to check in the bios. Perhaps it has something to do with this UEFI thing. I am a total newbie in this area.

Or maybe this SSD is slow and I got a bad unit? Still, that doesn't explain the slow boot. If I remember correctly it was fast while booting the HDD (this old drive had Windows 7/8 32 bit in it).

Or maybe Windows 8 is incredibly slow?

Any thoughts? I am out of ideas.

I've got the same SSD its fine. Boots into 8.1 in about 9-10 secs.

Altho I've enabled UEFI and secureboot in the BIOS. Dont know if that makes a diff or not tho. But if yours isnt on UEFI now, I wouldnt change it.

Otherwise it wont boot at all

Altho I dont have 5-6 hdd's in the case. Only thing in it is this SSD

It maybe one of those hdds. If one them is failing, or has errors or something. When you turn the system on it maybe having probs reading one of them.

I would say this would slow booting into windows down

I had a BSOD * and then the click of death started. Eternal loadings for boot and even Windows. Then turned PC off and on again. Started fine. Hours later, click of death BUT this time Windows was not affected. Just the faulty HDD disappeared from bios and everywhere else.

* reason given was irq less equal and perhaps zone alarm was responsible for this. Then again the PC was infected by malwares, and no new bsods appeared after formated and reinstalled. No signs of anything wrong, just the speeds.

Is this the reason things are slow? I will remove this HDD later, but I didn't know a HDD that isn't even being used for the OS could affect performance.

BTW what is this UEFI thing and what difference does it make when installing Windows?

Now everything it's OK. BOOT and Windows taking seconds to load, benchmark with proper speed... After removing the dead SATA HDD. So if a drive dies everything is slower in a computer? That's interesting.

P.S. This SSD had the firmware updated.
