Soo 480-512GB drives....need advice

as long as you enable ACHI before install you are good i think...i seem to be good now on install 3.2.....alienwares are absolutely retarded with install process. I have owned 4 laptops and 6 desktops and never had this problem with BIOS or drivers. Also your damn resource disk doesn't come with everything -_- Next time i am just paying dell to install because this was ridiculous on all the crap that wasn't on disk and the disk is garbage and some you have to use disk because they are not online. The drivers and support page has only a fraction of the files you need so i had to google some, use the disk, and dells site. epic fail dell -_- Even ASUS has a fast install process. Every driver is on disk and auto isntalls and online it has everything...sigh

Also anyone know why i only have 16GB instead of 22GB of ram?

Also i am trying to figure out why i don't have sleep. powercfg -a says it is a VGA driver thing but i installed everything in the right order and used dell's drivers. Is it because i am in iGPU right now?

EDIT: note i appear to be good and do not have to reinstall a 4th time. I guess i was on iGPU and when i installed drivers AMD didn't take. I just redid AMD drivers after nearly 200% reinstalled and i appear to be good *phef*

 

Just wondering if your issues with 840pro were only with one laptop or did you raided them on desktops also? im very interested as im planning on rebuilding my desktop for Haswell, kinda was hopping to at least raid 0 2x 840pro (maybe 4), but your comments got me worried.

 

Dude just wait for the m500 you'll get q faster drive and more.space for less, especially if you waiting for haswell than it'll already be out by then. I just couldn't wait for an unknown date but I am content.

 

Which OS?

Windows 7 Home Premium only supports up to 16GB.

 

ah yea thanks for replying. I did some googling and noticed home premium only supports 16GB...so dumb

 

Just got the Samsung 840 set up in the Silverstone Raven RVS02 USB3 enclosure (apparently the only 2.5inch enclosure that supports SATA III). Weird thing is though Intel RST reports SATAII active. Speed is about 365mb/s Read and 345mb/s Write in CDM which tells me its probably bottlenecked SATA III performance instead of saturated SATA II. This is unusual but expected (Read should be 560mb/s). I would like to see a UASP enabled enclosure with SATA III which might enable 560mb/s read speeds .
I realized that TRIM is not supported over USB3.0 so I'm curious as to how good the GC is on the 840 drives. I'm filling it up now and will delete the contents to see, will report back...

My laptop has SATA III but I don't think thats relevant since the 840 500gb drive is in a USB enclosure. Its just I think the USB3.0 interface is bottlenecking the SSD because I haven't encountered any SSD that provides these speeds with SATA II which is what Intel RST is reporting. Even at 96% Full it reports 360mb/s Read and 339mb/s Write

 

read should be 480-500MBps. i should have a screen shot of mine posted. Also did you get the 500GB or 250? speed is different on them. But for SATAII that is really fast. You should at best get 300MBps but 365MBps is really good for that ^^ Are you sure your laptop supports SATA3?

Can't tell by sig which you have it in

 

I just installed a 500 GB Samsung 840 into my MacBook Pro using an OWC Data Doubler. Putting a SATA 3 SSD into the optical drive of an MBP is generally considered a no-no, particularly on 2011 models. Many times doing this results in erratic system behavior at best and an outright refusal to work at worst. So far, so good. OS X reports the Samsung running at 6 Gb/s. On the Windows side, CrystalDiskMark confirms this, with read and write scores of well above 450 and 350 MB/s, respectively. Thanks to some tips from the OCZ forum, both SSDs are running in AHCI mode in Windows as the default install by OS X Boot Camp is IDE/legacy. While hacking the master boot record isn't without some compromise (sleep no longer functions, and Apple's Boot Camp Control Panel becomes inaccessible), the extra performance and enabling of TRIM more than makes up for it. Can't complain about the price either - $280 from Amazon.

 

My laptop has SATA III, my Samsung 840pro is getting 540mb/s Read and 500 mb/s write but I don't think thats relevant since the 840 500gb drive is in a USB enclosure. Its just I think the USB3.0 interface is bottlenecking the SSD because I haven't encountered any SSD that provides these speeds with SATA II which is what Intel RST is reporting. Even at 96% Full it reports 360mb/s Read and 339mb/s Write

 

ah you didn't specify you were using USB 3.0...I thought you said eSATA. It is definately USB 3.0 bottleneck

 

OK just tested it on my laptop
Overall results:
Desktop ASUS P8Z68 Windows 7 with ASUS turbo USB3.0
340mb/s Read 335mb/s write

Laptop W110er Windows 8 with native UASP USB3.0
400mb/s Read, 340mb/s write

On my desktop, for the life of me I can't get UASP working even though my enclosure supports it , oh well.

 

how does laptop not show up 450-500MBps? Also what is uasp?

 

UASP is the transfer protocol which is faster than the normal USB3.0 implementation. I was surprised the laptop was able to transfer 400mb/s over USB 3.0 to the 840 which is pretty much the limit of USB3.0. Windows 8 has UASP drivers standard whereas Windows 7 needs it to be provided by the motherboard vendor. Some guys on the Macbook Pro forums reckon it is possible to push 500mb/s if the UASP becomes more refined. I'm getting really curious now what kind of transfer speed is possible over Thrunderbolt.

 

interesting that is news to me. Thanks!

 

alright maybe someone can help me here. My SSD has appeared to be slowing down....a lot. If i haven't opened word or eexcel for awhile it takes like 5 seconds to open but after i open it once it opens quickly....it never did that before. Is my SSD going in a sleep mode or something? this 5s to wake up and work is annoying. I will click on the icon and nothing happens for several seconds...on a disk drive it'll open he program instantly but takes several seconds to load....never seen a delay though.

 

I'm assuming this is the only drive? There are no weird intel RST cache msata drives on the mmachine?
Let's go through the obvious issues first
Have you checked the alignment? Windows 7 sometimes gets it wrong can try hgst alignment tool.
Is your bios set to ahci?

From experience, ssd tend to slowddown with use though it is usually the write speeds. What you are telling me could be the ssd might be sleeping as per power plan. Or it could be caching your word doc in to its dram buffer. Or your DIpM/HIPM settings are too aggressive

 

I'll double check power settings when I get out of bed but hard drive sleep should be off. Achi or whatever is on....found out the hard way and had to spend another day reinstalling everything. There is a sata harddrive in there but it is just data....as far as I know.

Never heard of this alignment thing so can u explain that please.

 

Theres a really good guide here:
How to: Properly re-align your SSD/HDD partitions

In a nutshell, alignment is simply how well your logical partition blocks are "lined" up with the physical blocks. A misalignment causes a logical block to occupy two physical blocks thus greatly reducing performance and amplifying SSD problems.

Theoretically, TLC NAND should have longer access times than MLC NAND but not enough to cause a 5 second delay.

 

this thing is supposed to be even faster than the m4 and 830. I am going to check sleep now and check that thread out this weekend. I have never heard of this alignment thing so it will be interesting to read. I did another Crystal disk mark and i have lost 10-20% performance but i think that is expected with 50% filled or so......forgot what i was going to say :/

 

Also check that TRIM is working with TrimCHECK

You can also try Samsung Magician and use the Optimize performance feature that forces GC to work.

The 840 has really sluggish garbage collection to preserve the life of the TLC cells.

 

so is there anything new coming out in SSDs in the future? what are some of the best budget/band for your buck SSDs in the 500GB range now? Is it still the m500 and 840?

Is there going to be any changes in the near future that really affect the 4k reads/writes?

also where do i get samsung magician? did it comes with the SSD? if so i'll have to dig it out.

 

See:
Support - Solid State Drives MZ-7PC064D | Samsung Memory & Storage

 

tiller do you think there is a notice able difference between an 840 500GB vs an m500 480GB? I know the 840 can actually be a lot faster but i have a lot of stalls. We have concluded that is garbage collection right? What are your thoughts again between an 840, m500, and a 840 pro (or equivalent?) I am pondering about buying another SSD off Rakuten depending the price due to the 30% rakuten point sale going on if you spend 500-800 bucks. I need to buy lens for my D5200 and i know i have extra room in the 800 dollar max plus my $400 total rakuten points saved after this order.

 

Why don't you try updating the firmware and see if the stalls are gone. I hope you have backed up your data. There are some tweaks in the firmware to enable higher stability of the drive during operation. I am running a Samsung 840 too. I don't see any of these issues in my drive. I have about 30% of my drive empty but no drastic slowdowns you have seen. Try updating through the Magician software.

 

i am still doing that too. I was figuring i might buy a second SSD on rakuten while i got a chance and put the 840 on my netbook or use both in my R4. I just haven't had a chance. I am sure that'll fix most of my issues. I am quite pleased even with the few hiccups...i knew that getting into it ^^ But thanks for the reminder. I'll probably do that after my classes are over for the summer. Also having a second drive that i could clone it to would be really nice.

http://forum.notebookreview.com/off-topic/726052-need-help-coming-up-buy-list-rakuten.html

this is the thread of things i need help buying. I was looking to maybe buy a USB 3.0/eSATA dual dock that also does cloning. I have seen them on newegg for like 60 bucks but i never know what would be a good one. they have tons of brands and i am hoping someone has experience with them.

 

Odds are for M500.

FWIW I don't think you're stupid, but are you a numnut or what?

 

Debatable ^^ but aren't we all at times ^^ I also come across far more stupid on the forums because i suck at trying to put my thoughts into writing.

Looks like the m500 960GB drive is back in stock.....hummm should i migrate to the m500 960GB at main hardrive or use it as storage/games? I could just fix my 840 and use it as main but i am unsure if having larger main would be better or having larger storage/game drive. Right now games are on my main.

 

So I'm in a similar situation, looking to add an SSD to my new Lenovo W530 laptop and looking in the 500gb range. The prices are really making this difficult so I have a two drive's I'm considering, but wanted to hear what other's think about them.

$285 OCZ Agility 3 480GB ( Amazon.com: OCZ Technology 480GB Agility 3 Series SATA 6Gb/s 2.5-Inch Midrange Performance Solid State Drive (SSD) with Max 525MB/s Read and  Max 30K IOPS- AGT3-25SAT3-480G: Electronics)
$324 Samsung 840 500GB ( SAMSUNG 840 Series MZ-7TD500BW 2.5" 500GB SATA III Internal Solid State Drive (SSD) - Newegg.com)

So out of these two, would it be worth it to pay roughly $39 more for the Samsung, or is the OCZ a worthy contender even though it seems to be an older model? Considering the Samsung is already more than I want to spend, are there any other drives in this price range I should consider? I'd like to keep roughly 500GB, but am consider stepping down to a 256GB.

 

do a camelcamelcamel.com price watch on the 840. They go as low as 280-300 so just wait for the price is right

Samsung Electronics Samsung 840 Series Solid State Drive (SSD) 500 GB SATAIII 2.5-Inch MZ-7TD500BW | Amazon price tracker / tracking, Amazon price history charts, Amazon price watches, Amazon price drop alerts | camelcamelcamel.com

put a price watch at 300 and wait for it to drop. You cna add a price watch on newegg.com too.

Also i would rather get the samsung to be honest. I thought the OCZ were flaky for the 3rd gen ones. I could be mistaken. Also read reviews on tweaktown. They have really indepth reviews

 

Agility 3 asynchronous NAND run away... fast. Old review but you'll get the point on the first page.
AnandTech | OCZ Agility 3 (240GB) Review

 

interesting. I went with reading a hard forum review on it...had better explanations....very interesting. I never knew about that. I only looked into the market at the 830/840 m5/m500 time and avoided sandforce or whatever

 

so how many writes can an 840 500GB ssd make? I thought even todays low nm TLC was good with like a 1000 writes still....but i was looking and from what i though i read on anandtech that it was 100 writes before the SSD is dead....


i am chilling at about 5TB written so far in the last <8 months. From what i read on anandtech i have cleared through 10% of the SSDs life....is it really that low of life? I thought it was higher from what we were discussing earlier.

 

It should be guaranteed for 1000 though extensive testing by HWingnut (hes currently hammering away at a couple of 120gb models) is looking like they're over engineered for about 1500-2000 cycles, and hard failures haven't even shown yet. He did find that read speeds start to tank out at about 1200 cycles.
Bear in mind too that the larger 500gb drives have more space for wear leveling so you are less likely to use up P/E cycles for each I/O operation.

 

Kara was telling me in the anandtech review of the m500 that the 72TB is per nand cell aka per 128GiB cell if that is so than the 960GB drive is good for ~648TB of writting. The 1500-2000 cycles HT is talking about is probably the extra flash they put on it. Kara was telling me that the m500 960GB probably has 9 128GiB cells


Does that seem right?

Though according to anandtech review the 840 standard one has only about 50TB of write for the 500GB one, which is super low in my eyes. They were assuming write amplification of 10 for their estimate.
