  1. As if the Sata-3 market not was saturated enough. M.2 and NVMe is what most potential buyers looks at. Maybe a mSata ssd with included 2.5" adapeter could have made more sense. I already settled with Samsung PM830 128 and 256gb. Superb MLC SSDs which I prefer over the newer 850 Evo mSata.
  2. I'm debating which one I should go for of these three. The reason I need to go with mSata is that I'll use one or two with mSata to IDE adapter in laptops with that old interface. I'm aware of that the TLC based 840/850 Evo may lose data if they stay powerless for too long which may cause problem. How serious is that issue? The laptops will probably not be used a whole lot. Is the MLC based 830 mSata also affected by this problem ? I would guess not but asking as I'm not quite sure. Having had a look at what these drives go for on Ebay I see that the small price difference is nothing to care about. I had a look at the 850 Evo msata review and see that it seems to use same Nand as 840 Evo msata and that there is not is a whole lot of difference in performance. I've noticed that 120gb is the smallest size for 840/850 Evo msata, while 128 gb for 830 msata is the next largest (the smallest is 32gb) in that series. Am I right or wrong if I speculate that the 830 msata 128gb might be on par or even ahead of the 840/850 Evo 120gb in R/W when connected to a Sata III controller? - since Samsung seems to have had "problem" with the two smallest drives out of four different sizes in the same series in the past. I've vague memories that the 830 2.5" 128gb not got very good verdicts for performance as it was the next smallest drive, while the 256gb was better. Unlike 830m sata series, the 2.5" went up to 512gb. http://samsung.com/us/business/oem-solutions/pdfs/PM830_DCE_Product%20Overview.pdf I don't know however this size/performance problem remained or not for Samsung with newer series like 840 and 850 Pro. I'm thinking of potentially use these drives in a some newer rig later on as well so that's why I thought about performance differences. With that said I'm still not very tempted use RAPID which 840/850 Evo offer but I'll be ok with the "real deal"
  3. Now that Samsung still are struggling to get it right with their TLC Nand I think I better stay clear of the 840 Evo, 850 Evo mSata as well as they both uses same Nand unlike 850 Evo 2.5". I knew about the problem with TLC drives losing data after some months, though not how many months which it takes. About 4 months according to the link. Good to see that the 830 mSata 128gb which uses MLC not is too far behind the 840/850 Evo in performance. Approximately what I believed as the 840/850 is the smallest drives in their series unlike the 830 128gb mSata which is available in 32, 64, 128 and 256gb. So I think I better go for the 830 mSata 128 or 256gb then. Not quite the fastest option but as that doesn't matter for most of the time as it is going to be used with Pata-interface and it should be far less troublesome as it is a proven good product. Samsung needs to get it right with their next firmware before I can consider any of their TLC drives.
  4. Luckily Samsung finally released a firmware in november last year for the 840 Evo mSata as well, as previously the 2.5" Evo. As I assume that's the long-term performance issue you thought about? Surely the 830 is the oldest of these three but as i said, the 830 128gb mSata is the next biggest in the 830 mSata line. Meanwhile the 120gb 840/850 Evo mSata is the smallest in the 840 Evo mSata series and Samsung seems to have had less good performance with the two smallest sizes in a each series for some time. Shouldn't that mean that the 830 Evo mSata 128gb should be perform well compared to the 840/850 120 mSata ? After all the Samsung 830 series was top-notch when new and the predecessor to 840 Pro while the EVOs are real consumer drives, using TLC Nand. MLC for 830.
  5. Seems to me like it is TLC-nand 850 Evo instead of MLC 850 pro http://samsung.com/global/business/semiconductor/minisite/SSD/global/html/portablessdt3/specifications.html At least that's what the sizes of 250 and 500gb suggests as 850 Pro not is available in these sizes but 256 and 512gb. Would have been harder to tell had these T3 drives only been able in 1 and 2tb, considering that Samsung not mention in the specs if it is TLC or MLC. Weird that the warranty is only three years compared to 5 years for 850 Evo and 10 years for 850 Pro. And I don't think it could be the 840 Evo or Pro because these ssds was not available in 2tb. Somewhat weird that it is only 3 years warranty for this Portable ssd considering that 850 evo have 5 years warranty and 10 years for 850 pro.
  6. To try and make a long story short. After having tried to find a suitable old quality ssd for my motherboard which only have sata 2 controllers, I finally settled with a 850 Pro 256gb anyway. It seems to me that my motherboard only have Pci Express version 1.1 which have no better than 250 Mb/s which is no better than the built-in Intel sata 2 controller, even with a sata 3.0 adapter card connected if I've got this right. There is two Pci-e slots in my Ga-Ep-35-ds3p motherboard which makes it possible to use two ATI Gpus in Crossfire. According to the bios boot options the board supports boot from Add In Cards. Not sure if that's only Pci express but also the faster pci-e slots. The official specifiacions for my motherboard http://gigabyte.us/products/product-page.aspx?pid=2742&dl=1#sp Either way I've way if there is some low cost card for Pci-e to Sata 3.0, 3.1 or 3.2 I would probably be prepared test if it works to boot from.
  7. Samsung 850 EVO SSD 2TB Review

    But isn't those reliability problems related only to the 840 Evo-range and 840 Basic ? 850 Evo uses newer Nand which not have this problem as far as I know. Still bad support/business tho by Samsung not releasing firmware update to the 840 Evo mSata and 840 Basic. And it seems to me like they'r getting away with it reasonably well unlike IBM with their "Deathstar" series of HDDs. Samsung should take better responsibility really. I don't know if anyone ever tried to file a Class-action Lawsuit against Samsung for this mess for the SSDs not receiving firmware updates. That's what some guy did against IBM so that they had react. https://en.wikipedia.org/wiki/HGST_Deskstar#Lawsuit
  8. I'm looking for a used 2.5" or mSata Samsung 830 or 840 Pro. 256 or 512gb of these. May consider a 850 Pro if the price is right. I'm not interested in the "usual" 840 or 840 Evo due to the problems which those have. Other quality ssd units which are equal to 830 or 840 Pro in terms of reliability and performance might be of interest as well. Only MLC and SLC are of interest.
  9. Ok. So with what I got to know by Brian in Pm after his reply this thread means that I'm still looking for alternatives. So if anyone else have some ssd which they want sell so let me know. Either in this thread or Pm.
  10. I'm still looking for one of the mentioned ssd drivers or some other good MLC or SLC ssd. The reason for the fallout regarding the PM830 seems to be the 256 bit encryption and that the U.S have some export ban for such drives which not includes Sweden as I've bought an enterprise in Sweden which have 256 bit AES hardware encryption. I've told Brian that in Pm, but still after about 2-3 days have got no reply at all. At least one might expect an answer. So I'm still looking for other options unless I can have the PM830 or buy some other Samsung ssd which have been used for testing or been in use. As it is an old computer with only Sata 2 I don't need or want the newest and plan to use the computer for 1-2 years to come. So buying a brand new which would be a little slow for a new computer now would be a waste. Because obviously M.2 interface is the way to go with new computers. Something which my old Intel 775 motherboard not supports.
  11. Too bad that Samsung sold their Hdd division. They may have been able to get it right with a decent SSD chip and at least a reliable hdd.
  12. This SSD/HDD should have been named WD Blue2, not Black2 considering what drive it in fact in based on and the filthy SSD unit. Wasn't hard at all to guess that the SSD performance not would be very good considering that most 128mb SSDs usually performs less well compared to their 250 or 256mb "relatives" from same manufacturer. As said by jtsn, this SSD/HDD is a joke, a very filthy such. May I ask if it is known what manufacturer is behind these two 64gb SSD chips?
  13. I had a look at the better 2TB drivers not very long ago. http://hardforum.com/showthread.php?t=1773467 I was looking for a fast and reliable drive to use for the OS et. In the end I went for the ST2000NM0053 which is an enterprise drive with 3 platter and 5 year warranty. Not quite as fast as the 2TB Barracuda but not too far behind either and the reliability should be better. This ST2000NM0053 is maybe not the best option if you want a quiet drive. It is in fact slightly more loud than my old Velociraptor WD3000GLFS which I now use to backup important files. One downside with the Seagate drives as far as I know is that it is not possible change AAM/APM. Silent pc review forum could be a good place to have a look at if you want a quiet drive. But these are usually not fast. http://silentpcreview.com/forums/viewforum.php?f=7
  14. 2.5" vs 3.5" reliability

    2.5" should be more reliable as these are designed to be used in laptops. Problem with heat is also less of a problem even with my former Hitachi Travelstar 7k100 IDE, which as the model name tell is a 7200 rpm drive. Had that drive mounted in a slimmed noname magnesium or aluminium cabinet for quite some time before I let it replace an other drive in an older laptop. Even modern 2.5" 7200 rpm drives however like the 1tb Travelstar 7k1000 seems to lag behind the better 3.5" 2tb drives which I've had a look at not long ago. http://storagereview.com/hgst_travelstar_7k1000_review If you are interested in 3.5" then there is at least two writeup which might be of interest. 2TB http://reybasti.hubpages.com/hub/Top-5-Best-2TB-Hard-Drive-For-2013 Worth to mention which he not did is that the 2TB Barracuda only have one year warranty. And the 3TB http://reybasti.hubpages.com/hub/Best-3TB-Hard-Drive-for-2013
  15. If the Hitachi Travelstar drives still hold up as well as these did some years ago than that could be one way to go. I've some experience with these drives and have not found much to complain about. My first was a 40gb 4200rpm with 2mb buffer (forgotten the model number). A good and reliable drive despite a lot of use in at least 6 days in every week. I finally upgraded because I needed more storage but also because I wanted a faster drive. I went for the Travelstar 7k100 with Ide interface, which my laptop had. I also had a look at Seagate, I think it was, and their equivalent 2.5" Momentus 100gb, 7200rpm with 8mb cache but the Hitachi had better read/write performance according to tests if my memory serves me correct, so I went for the Hitachi. My Hitachi 7k100 is still doing a good job after having seen daily use in first an other laptop which I used every day. It is now sitting in an old laptop which run a gameBot 24/7 and the drive never seems to spin down as it makes a slight ticking noise sometimes. Still working well. I've another Hitachi 7k100 though with Sata interface in an other Core 2 Duo based laptop. Probably the stock drive I would assume as I'm the second owner of that laptop. I'm not using that laptop much but it works whenever I want to use it. My experience with these older Hitachis is that the general performance was good for the time being and reliability as well. Edit: Oops. I now see that you are looking for a 3.5" drive. I was thinking about 2.5" as you mentioned the Macbook.
  16. Since like the middle of 2012 I was thinking about finally replace my Velociraptor WD3000GLFS (The original Velociraptor) with a SSD and very likely the the samsung 830 250gb which had good performance and decent reliability. But as I knew that there was only a minor couple of months until the announcement of the replacement, the Samsung 840 and 840 Pro, I decided to wait to at least see what it was like in comparison to the older 830. I was rather disappointed with the small increase in performance. 250gb 830 vs 840 Pro and despite some other small though probably good improvements the 840 and 840 Pro looks like nothing more than just a small step between the 830 and some real upgrade in performance. The price of the 840 Pro 250gb has come down here in Sweden, almost to the same lowest price, which the 830 250gb has been available to for like the last 8 months according to price-comparing sites like Pricerunner etc. Now when Samsung acquired Nvelo (link)which is a caching maker for SSD units. Is it as I believe, that there is a bigger, more significant step up in performance to expect from the successor of the sooner or later upcoming replacement of the 840 Pro 250 and 500gb rather than the imo disappointingly small improvement btw 830 and 840 Pro 250gb?
  17. Not more than one year or possibly one and half year as longest I would assume? It seems obvious enough to me that Samsung are about to use the Nvelo development and their caching technology to increase the write and read-performance flow in their SSDs. Maybe some other things as well which I not know about as I've not read a whole lot about Nvelo just yet. Feels like a damn waste buying a 840 Pro now, knowing that the replacement almost certainly is about to be the real upgrade from a Samsung 830 250 gb that the 840 pro should have been. Well. I'll think about what to do even though I've not dismissed the 840 Pro entirely just yet. But certainly I would prefer to buy the real upgrade.
  18. You say no 6gb/sec interface. I assume that what you have is Sata II then, correct? Sata II itself should not be a lot of a bottleneck I think. Might have been far worse if it was the first gen Sata I. At least that's what several owners of Lenovo laptops go to experience when Lenovo deliberately cut the fully Sata II controller down to Sata I standards because them had some old obscure Docking-station which them wanted to be fully compatible at every bloody cost - Eventually it cost them some reputation among the owners of Thinkpads Anyway. One guy whose username is Middleton in another forum modified the bios for what I think was all of the affected Thinkpads to enable Sata II again among some other things. At least one other guy which had the actual docking station used it to copy files between the hdd in it and the laptop, with the modified bios, and he reported that it worked well.

  19. 2X3TB Red vs 4TB Black

    In terms of performance two Red 3tb in Raid should likely give you faster transfer speeds than one Black 4tb.Though it is hard to know for sure until tested/experienced how well the two drives will get on together. But it would likely consume more power as well even though one Black 4tb should consume slightly more power than only one Red 3tb. 3 year warranty for WD Red 3tb and 5 year for Black 4tb. However the length of 5 year warranty makes sense or not depends on for how long you are expecting to hang on to the drive. I'm almost on my fourth and half a year of a 5 year warranty with my original Velociraptor WD3000GLFS bought during the summer in 2008 at the time when I built a completely new rig after having been sitting with a Pentium 3 1.13GHz laptop and a slower tower for too long That drive is still going strong although it is up and running for 24/7 with some very rare exceptions. 34567 hours and counting, for my Velociraptor. In terms of noise I don't know for sure even if it might be realistic to expect the two Red 3tb to cause more noise together than a single Black 4tb. I've not heard any of them running but would be surprised if any of them makes more noise than my Velociraptor which is not very loud. At least the spin noise of 7200 rpm compared to 10k rpm for the Velociraptor should be more quiet unless WD have been screwing around badly. Edit: An other user on this board have his report of Seek noise with WD Red 1tb. Though I dunno however it is the norm or just for his drive. Edit again, His drive was Red 1tb, not 3tb. Somehow I first got that wrong! So, If I've got this right, the 1tb should be from a previous, older generation of WD Red drives than the 3tb. Just like my old Velociraptor not is from the same generation as the newer 600gb or more recent 1tb Velociraptor. And thus the the post about noise for the by the WD Red 1TB is likely not representative for the WD Red 3tb.
  20. I don't know for sure about their 3.5" drives. But at least Toshiba made their own 2.5" drives for a couple of years ago and these almost always trailed behind the Hitachi Travelstar 2.5" drives in terms of performance so these was probably not the same.
  21. SCSI HDDs

    Not very well with the bad SATA support in with that old Linux kernel. I don't know any SSD which connects through IDE interface. But some users of old Amiga computers uses either Sd or CF cards and a CF/SD to Ide adapter as SSD for their Amigas. I don't know how reliable these cards are compared to SSDs though.
  22. SCSI HDDs

    Then according to his first post, a SATA drive with SATA to IDE adapter would still remain as a good option according to a short line in his first post which I highlighted in the quote below. I don't know how much of a bottleneck using a Velociraptor or any other high performance SATA drive in actual Ide-mode might be other than the lower bandwidth which Ide has. On the other hand the Velociraptor should have better performance overall than a SCSI 15 rpm with at least one possibly exception. The seektimes which I think should be shorter for a SCSI 15k rpm drive. The SCSI might have some other advantage also which I not know about as I not have the same plenty amount of knowledge about harddrives unlike many other forummembers here. Also unless the sellers on Ebay or craiglist of used SCSI drives might be able to tell for how long time or many hours the drive has been in use, that would remain unknown for how many more years of service the drive should be capable of. I've not looked or studied the specifications of SCSI drives very narrow any time. But I would assume that the standard warranty should be at least 5 year or more, which then would equal the 5 year warranty which seems to be standard for the Velociraptors according to information on the upper half about warranties on following site. A used SCSI should be more inexpensive than a VR though you'll have to find a controller-card for it unless there is an integrated such on the motherboard which is going to be used. http://support.wdc.com/warranty/policy.asp?fid=wdsfVelociRaptor
  23. SCSI HDDs

    Also the Western Digital Velociraptors can be considered as a good alternative to Scsi 15k rpm. The Velociraptors are 10k rpm, good reliability from my own experience, decent performance to be harddrive and probably more silent than a Scsi 15k rpm drive. with that said I don't know how loudly more modern 15k rpm Scsi are but at least early such was infamous for the sound level. Can probably use a Sata to Ide converter if that works.
  24. SSD Giveaway Thread!

    I'm in for a SSD. May need one as a complement to my aging Velociraptor WD3000GLFS which is the only drive in the rig.
  25. The Hard Drive Giveaway Thread!

    I would like some drive, 500Gb or larger as a complement to my Velociraptor WD300GLFS which is the only hdd in my rig. I've begun to run out of space recently and need to add another one sooner or later.
