Samsung or OCZ?

Hello im configuring a notebook and i happen to come across multiple choices for SSD and i cant decide really.
i did some research, still cant decide on what to do so here i am..

These are the Only choices ( with price in brackets )

64GB ADATA SP900 SATA-III 6.0Gb/s - 550 MB/s Read & 505 MB/s Write [+78]

64GB SanDisk SATA III 6.0Gb/s SSD - 490 MB/s Read & 240 MB/s Write [+67]
128GB SanDisk SATA III 6.0Gb/s SSD - 490 MB/s Read & 350 MB/s Write (Single Drive) [+103]

128GB OCZ Octane SATA-III 6.0Gb/s SSD - 470MB/s Read & 210Mb/s Write [+67]

120 GB SAMSUNG 840 Series SATA-III 6.0Gb/s SSD - 530MB/s Read & 130MB/s Write [+106]


i heard samsung 840 series is the best out of these ( its not samsung 840 pro )
but considering its $40 expensive then OCZ im getting inclined toward OCZ. i also heard samsung has twice the iOPS.

Do you really think theres a huge difference? i want to go with OCZ Octane, is it a good SSD?

 

We hear and receive more issues arising with the OCZ drives and the SanDisk drives than anything else. The Samsung 840 is good, though the 830 is a better performer and the 840 Pro better than both.

You can check out benchmark comparisons here. As far as reliability/dependability goes, Intel, Samsung, and Crucial are the top three. We very rarely get any cases with the Intel drives.

I've no personal experience with the ADATA drives though.

 

Unfortunately, some of the drives you mentioned are also extremely untested. If you are going for Sandisk, try to get their Sandisk Extreme, at least that drive is fairly well proven provided you can deal with the issues of Sandforce. I am confident the Sandisk drives mentioned at the Sandisk Extreme Plus drives, the controller is Micron I think but I don't have any experience with this model.
I would never choose the Samsung 840 120gb when the 830 can be had for the same price. TLC is still too untested at the moment, I'm actually watching my 840 500gb drive like a hawk for any issues. You should check out this page Components returns rates (7) (page 7: SSDs) - BeHardware

I know it was the SATAII Octanes that had issues (I had 3 consecutive DOA drives until I went and got my money back) but I am extremely wary of the SATAIII versions as they use the same controller with probably the only difference being NAND quality and interface.

I think your best bet is to decline the HDD upgrade (or get an el cheapo 500gb HDD) and do the SSD upgrade yourself. I would avoid older OCZ drives (hey, they got their reputation from somewhere right?)
In the budget space, the last gen flagship drives are actually the best, try to find the following:

Samsung 830: best all round drive, nuff said

Crucial m4: brute reliability, all the issues have pretty much been ironed out, comparatively slow these days

Plextor M5S: same controller and NAND as the m4 (therefore probably similar reliability), Firmware is tweaked for Faster Random Read (i.e. snappier windows) but slower Random Writes (worse for database apps), also much more aggressive garbage collection. Firmware update process is pretty bad though (you gotta make a Linux bootable USB flash drive)

Sandisk Extreme: fast, efficient and cost effective Sandforce implementation, I think they finally fixed the TRIM issue it had at launch. Sandisk are a little slow with firmware updates though.

Intel 330: extremely reliable Sandforce implementation coupled with quality NAND, rather expensive and slow for its price though.

 

...................

 

I partially agree with Marksman30k. Sanddisk Extreme as the name indicates is extremely good atleast for me. I am loving this & as Marksman says TRIM has been well patched and the build quality is quite professional. SF based SSDs are scaling up their new highs again, i believe

 

Sandisk products have been a massive failure lately, had 2 memory cards fail (32gb class 10 the so called "sandisk extreme") if this one goes I'm getting a refund which seems quite likely at this point. Definitely wouldn't put any coin on a Sandisk SSD unless you plan to back it up every day.

OCZ seems to suffer from same reliability issues with SSDs, got a reputation for stopping. Haven't tried any, but had enough people complain about them not to buy one.

Would go with Samsung from the list, for the sole reason of OCZ and Sandisk reputation and the fact that i haven't heard anything at all about A-Data, plus having 120gb SSD myself, it is tight on space as is, couldn't imagine anything done on it with only 64gb

 

i wonder why is samsung 830 better then 840 series, but i guess writing wont be a major thing for me since it will be just for OS and programs only, Data drive will be 750gb 7200rpm,
thats why i wont be tight on space, only purpose is to have faster OS and working with programs, and for gaming it will be HDD, i dont mind bit longer loading times in games.

As far as the stats show ADATA is faster then all of the ones, having more iOPs and also highest read/write speed. but im not sure about reliability so that is why i am here. i cant decide between the ADATA and Samsung 840 atm.
about Sandisk and OCZ i heard there are alot of issues specially with OCZ.

 

830 is better than 840, but not better than the 840 pro because the 830 and 840 ( pro) use Samsung MCX controller, with NAND 27nm Toggle-Mode 1.1 MLC. The 840 (non pro) uses MDX controller, with NAND 21nm Toggle-Mode 2.0 TLC.

Here's a breakdown of SLC, MLC, and TLC if you're interested: Chiptype - Centon Electronics, Inc.

 

OP: Pay $30 more and get the Samsung 840 Pro 128GB
Why?
Big difference and you buy a well known brand which have awesome quality on their products. You`re welcome


Samsung 840 120GB


Samsung 840 Pro 128GB

 

I haven't purchased A-DATA's SSDs, but have had success with their other flash memory products - memory card and thumb drives. They're usually a good value.

I'll second the Samsung recommendations. Samsung produces flash memory in its own (extremely advanced) fabrication facilities. Samsung is the gold standard for flash memory quality.

 

Samsung! I have had really bad experiences with OCZ, but none with Samsung 830 series.

 

If reliability is your primary goal (which should be on everyone's mind), then any of the Samsung SSDs (470, 830, 840/pro) will give you that. I speak from personal experience (not the 840 series though) and its been a good run for me. Firmware updates, when needed, are easy and the performance is good when the SSD is properly maintained. I recommend using at least the recommended "overprovisioned" aka spare area that Samsung recommends for consistent performance because if you fill up the drive write performance suffers.

 

Buy 840 pro

 

Pretty much agree here: Samsung will be your most reliable choice out of what OP listed. All of Samsung's stuff is built in-house, and customer support is pretty good. OCZ, while I hear that their drives have somewhat gone up in quality, is still a company I'd avoid simply because of the way they've treated their SSD customers not so long ago. That and they're still not as reliable as Samsung/Plextor/Crucial/Intel (the brands I'd usually recommend). Don't know a lot about ADAA or SanDisk's SSD products to judge them (though I've had great customer support experiences with SanDisk with their flashdrives and mp3 players, so maybe they'd make a good second choice to Samsung).

 

HARDOCP - Introduction - Samsung 840 120GB SSD Review

Looking at this review do you think 840 Samsung is really worth it, specifically the 120gb one, it has some severe latency problems, have a look at that review please then comment.

 

I've had 10+ OCZ drives and never had a problem with them except the original Core drive, which stuttered badly, but that was when SSDs were new.
