I wouldn't touch the pro unless money simply wasn't a consideration at all. If budget is not a consideration, you might as well have the fastest, but if money is a factor at all then basically any modern SSD from a good manufacturer is so fast you'll never tell any difference between any of them - the standard 840 is really quick, and much better value.

Thanks for the info. Im definitely looking at a 250gb this week. Im stuck on a 250gb 5400rpm drive since i first got my machine 5 years ago.

Well theres cheap and then theres the reliability factor. which is more what im after. I know RMAs exist but id rather have as little trouble as possible.. as i suppose everyone would.
Like i said, out of what you listed. Cheapest... Also look at the recommended drives list here for more: http://www.overclock.net/t/1179518/seans-ssd-buyers-guide-information-thread

Well there's absolutely (and I do mean absolutely) no substitute for a proper backup strategy. I lost data once many years ago - that will never happen again. Any drive can fail, and house can flood etc. Never rely on a drive to keep data you can't afford to lose.

Assuming you have that sorted, then of course you don't want your current drives to let you down, or at least you want to minimise the chance of that happening - I've had a bunch of OCZ vertex and RMAd a lot of them before I eventually outed them all and switched to 830s about 8 months ago and I haven't had a single failure yet, but I only have 3 of them.

Other drives, I can't speak from personal experience, but I know the Intels are widely regarded as very reliable but are very expensive, Plextor are also apparently very reliable. Personally I would buy nothing other than Samsung at the moment because I think they are competitive on price and seem to have excellent reliability.

Thanks for filling in your specs, it makes helping you so much easier.

Your speeds are pretty good. Here are my scores:


These drives aren't the fastest but I doubt you really notice the difference, what does make a difference is the size of the drive. While I'm very happy with mine I intend to upgrade in time to come as 120GB just isn't enough for the VM's and games I'd like to run off thise SSD.

I am very inexperienced, but I am pleased with my 3 month old 840 Pro. I have the 512GB version to go with my 1TB HDD. Maybe I should of gotten the 256GB model instead, but I like mine really well. It should last me quite a while. Its benchmarks are good too. They are posted a few pages back. So, my suggestion is to try one of these. Samsung seems to have fixed the early complaints. There is a new firmware available. Its Magician software has been updated plus Samsung has some Migration software. They have done a lot in the past 3 months to make the whole package very good.

I just bought a 256GB 840 Pro from amazon, It arrived today and I connected it to my 2 week old M5A97 EVO R2.0 however AS SSD bench reports 430MB/write and 3MB/s read - HD Tune Pro reports that I am getting <2MB read speeds and also reports warning in the health status to say the UDMA CRC errors reporting numbers of 7000+

Is this a faulty drive? I think it must be as I have tried in different motherboard ports, tried different cables etc.

My old Intel SSDSA2M080G2GC works fine and gets approx 200MB/s without a problem.

If anyone can suggest anything before I RMA the drive and go and buy an OCZ vector tomorrow I would be grateful.

Thanks,

Anyone using the 840 Pro with an LSI MegaRAID controller? I'm thinking of buying four of these drives for my LSI MegaRAID 9271-8i controller, and want to make sure there's no compatibility problems. Thanks.

If anyone can make any sense out of this I'd be very happy.







This is my intel on AS SSD



Intel Anvil (AMD drivers)



Intel Anvil (Windows drivers - storageahci)



This is a spare drive - on the same cables on the same board.

Sorry here are specs:

Name AMD FX-8350
Codename Vishera
Specification AMD FX(tm)-8350 Eight-Core Processor
Package Socket AM3+ (942)

model M5A97 EVO R2.0
Northbridge AMD RD9x0 rev. 02
Southbridge AMD SB910/950 rev. 40
vendor American Megatrends Inc.
version 1503

More info
I bit the bullet because I was going to RMA my drive and went and bought another 840 Pro from a local retailer.

This performed great I was getting approx 500Mb/s read/write out of the box.

Thinking that it was just a bad first drive it prompted me to get a a firmware upgrade, after the reboot I was back to slow speeds again. So I decided to try Linux.

I ran Ubuntu 12.10 off the CD and ran speed tests - both the drives are fine running at 560MB read and about 530MB write. I have even put them into raid and Ubuntu reports 1.1GB/s read speed and around 1GB/s write.

The raid set-up doesn't seem to like windows 8 even though I have loaded the driver from a CD at install.

I have secure wiped and set-up AHCI mode again as (separate drives) and I have just tried with Windows 7, same issue with slow speeds even with the chipset drivers from ASUS website. It seems like anything Windows on my motherboard on this firmware doesn't work but Linux is fine....

Any ideas?

Sequential don't make the slightest difference, only 4K. You are worrying too much and Linux is generally speaking faster than Windows, it's been known for a long time that SSD's bench higher but you won't notice the difference anyway.

Looking at your scores I'd say it's not abnormal for the MSAHCI driver to get higher numbers than the AMD one but I found that Windows simply didn't respond as well while running the MSAHCI one. It took noticeably longer for programs and Windows to boot than with the AMD one so raw numbers don't mean much.
