Noticeable Difference Between Samsung 840 Pro 512gb and 840 500gb? - Page 3

post #21 of 39
Thread Starter 
That Plextor M5 Pro 512 turned out to be a piece of junk. About a month of use and it has completely failed. First time that I got bad advice on here, but I guess it happens. Also, Plextor's customer support, warranty and Technical support phone numbers (both the 800 and area code numbers) have been taken out of service as of yesterday. I haven't had time to check today, but they were no longer valid as of yestersay. I would advise anyone to stay away from Plextor. Luckily, Newegg is making an exception and allowing me to RMA the drive through them, even though it's been longer than 30 days. I didn't even ask them for an RMA, as I just called Newegg to see if they had a valid phone number for Plextor and they immediately said that they will RMA it. My guess is that they have had to RMA many Plextor drives and so have many refurbished ones in stock to send back. That definitely can't be a good sign.

What really sucks is that I was in the middle of the online portion of one of my timed final exams when it failed. I had to rush to school to see if I could get online before the time was up and I wasn't able to (my laptop doesn't have the required software). So this failed hard-drive caused me to get an F on my final exam. So much for Plextor! Again, I would stay away from Plextor SSDs and go with a more reliable company like Samsung.

Looks like you would've been better served by 2x Samsung 840 500GB RAID-1. tongue.gif In any case, now might be a good time to RAID-1 your SanDisk Extreme 120GB (put on Intel SATA2 ports) and run the OS and critical programs from there.

The drive failure could've happened to any brand. Just sucks that it had to happen while you were taking your exam.

How did it fail, what happened exactly? How did you diagnose the failure resulting from the SSD and not something else?

It wasn't bad advise, you just never stated you needed 2 for RAID 1. tongue.gif

I called earlier today and they were fine. Are you sure you dialed the correct #?

They do that sometimes, I've had that for a failed WD drive.

You can easily talk with a dean and retake it. I've had the same thing happen to me before. My laptop died during a math final and I got a F. I spoke with the head of the math department and explained what had happened and I was able to retake it.

Good luck. Failures happen with every company, there is no way 100% of a companies products will be perfect. smile.gif

Love my plextors. As good as they get as far as I am concerned.

I have to comment on this. The 840 non-pro is not "do-do"...the only thing it's noticably bad at than other modern drives is sequential write, which you shouldn't be doing on an SSD anyways...you should probably have a 1TB HDD to be storing .ISO's and HD movies etc. The only thing I do that requires sequential write, (and I'm a pretty typical user) would be game installations which takes less than 2min on any SSD...The 840 is actually faster in some every day tasks than the Pro, like dealing with small files. 

 

It's actually the 840 Pro that is not worth a 40% price increase. The 840 is a fantastic drive for the price for savvy consumers.

While I agree with you that there is not a thing wrong with the non pro version why do you think you should not do sequential writes on an ssd ? It is not like you are going to wear it out.

I have seen no indication from anywhere really that the non pro out performs the pro, but funnier things have happened for sure. wink.gif

I'm not saying you should not do it, I'm just saying if you're going to be writing large sequential files, it makes more sense to be storing those on an HDD anyway because that's just logical. You want the SSD for operating system, game, and application usage. Most people wouldn't be paying $500 for a purely storage SSD when you can use a $67 1TB HDD.

 

The only time most typical users needs sequential read and write is with large .ISO's or installing games, or something like that, so, basing an SSD's performance on it's sequentials alone is an amateur assessment. It really comes down to the controller's properties, which is why the Crucial M4 Marvell was a much better buy than most of the Sandforce SF2281 drives for a long time; It was like $210 when the Vertex 3 was $290 and their performance was identical except for sequentials, which the Vertex wins at.

How? HDDs are normally ~100MB/s read/write. My SSD is 500MB/s read and 300MB/s write.

Explain to me how it is more logical to write large files to a slower HDD over a faster SSD? That is like saying it is better to drag race with a stock honda civic instead of a dragster.

All of the sudden, after only a minute or two into my test, I got a BSoD. Then, when I tried to reboot it would not reboot into Windows. After unplugging it from the SATA port and re plugging it back in, I could see it in the UEFI but it wouldn't boot Windows. I wound up putting in the OCZ Agility 3 120 and installing Windows. The SATA port works just fine because the Agility 3 is using the same SATA port. Oddly enough though, I can plug the Plextor into a spare SATA port and actually get access to the files. Thank god! I'm assuming that something went wrong with the master boot record, is that right?

I believe that the person who recommended the Plextor, did so on reliability. I have 4 other SSDs from three other companies and haven't had a problem yet, until the Plextor. What initially sold me on the Plextor, was the supposed reliability. From what I understand, Plextor charges a premium for that supposed reliability, therefore there shouldn't be any problems. I do realize that every company can't be perfect, but when reliability is touted as the main marketing pitch and a premium is charged for it, then I personally don't think that there should be any excuses. That's my opinion anyway.

I have since gotten through, but for at least 1-1/2 days, all of their lines were busy. They told me that there phone system was down. I guess I just had a failure at the wrong time. smile.gif

I vaguely remember getting something at the beginning of the semester that briefed us on the extra-tight rules regarding the exam. Oh well. The good news is that I scored 30% before the crash, so it's not like I'm working with a zero. My professor also said that while his hands are tied on the exam, he will drop my lowest test grade (other than this exam) and use my highest grade twice. That replaces an 81% with a 100%. When added to the 30% I got on the final exam, it equals 49%. So, while a 49% sucks and will definitely affect my overall grade, it's not like I'm having to work with a zero. I believe that my over all grade equivalent for the course will be an 85 B, when it should have been an A, so while it sucks, it isn't the end of the world. Still, I'm mad at Plextor for touting enterprise-grade reliability, charging me a premium for that reliability, and then shipping me a low-quality drive -especially when the low quality SSDs that I do own have not failed on me yet. Oh well, we live and learn... smile.gif

That sounds like windows crashing and corrupting, not a drive failure. Many things could have caused that. If you have the BSOD memory dump someone can check it out and help pinpoint the reason for the crash.

Well, based on what I read the drive may have not been the culprit of the crash and the SSD has not failed. However, we won't know unless the crash dump can be analyzed. Also, it could have been corruption from a system overclock or system update or driver crash.

frown.gif that sucks, well at least you still get a fairly good grade. Better luck next semester! biggrin.gif

Also, failure's happen to all companies, the drive is not low quality, and again, seems to me as if it did not fail. tongue.gif
