  1. I think they'd like me to buy their "Game Drive for PlayStation 2 TB" product with an additional 30-50 % cost added for what might be a slightly modified firmware. Looks like in few years from now I might just end up with a 2+ TB SSD for that use case.
  2. I tried upgrading a PS4 with that Seagate 2TB SMR drive and it didn't work reliably. Locked up and corrupted data multiple times, Console couldn't boot anymore and had to be restored from backup. Everything returned to normal once it got reverted to the 1TB factory HDD (made by HGST). Outside this application the drive still seems to work (albeit very slow), but it shows that SMR outside of special applications isn't really ready for prime time, despite Seagate trying the hardest selling to consumers. Without even specifying on the drive what you get - I just ordered a 2.5in 2 TB drive and didn't even know what the issue was, until I found out it was SMR. Interestingly there is now no <=9.5mm PMR drive above 1 TB in production anymore.
  3. WDC Red Pro 8TB Too Quiet

    I just got hands on my first He drive by buying a WD My Book 8TB (WD80EZZX). It's surprisingly light for its huge capacity and it's the most silent 3.5" drive I ever had.
  4. WD Blue SSHD 4TB Review

    The 8 GB NAND cache is still too small to really help games. The newer games which profit from SSDs due to asset streaming are so large (up to 50 GB), that this small cache doesn't help them. Older games which fit into the cache OTOH don't really need this. These are usually designed with very slow optical disc operation in mind and a conventional hard drive is more than fast enough for them. Is still view SSHDs as benchmark tuning device.
  5. SECURE ERASE is a standard ATA command, which any utility can send to the SSD/HDD, provided that the SSD/HDD was not set to SECURITY FREEZE before. Usually the motherboard firmware or maybe Windows 8 and above does that to prevent malware from permanently locking your SSD/HDD. I usually use Linux to secure erase disk drives, because the Linux kernel can be configured to filter out the SECURITY FREEZE command, when you hot-plug a SSD/HDD. Otherwise you can't use SECURITY commands. There is a good reason why those SECURITY commands are specially protected: These command allow to permanently lock (aka brick) a SSD/HDD drive by setting a password. In fact the SECURITY ERASE process consists of locking the drive with a password and then unlock it again by securely erasing it with that password. If the process gets interrupted in the middle by a power failure, the drive is still locked. So doing this sort of stuff is something I only recommend for experts.
  6. Interesting innovation, but I would be more interested in having drive-less bus-powered enclosures to put my own 3.5in hard drives in. I'm not really fond of having to buy a unnecessary Seagate HDD with it. For me the power supply thing is mostly a non-issue, because I use bare desktop drives inside USB/eSATA docking stations and tray-less mobile racks. Docking stations stay on the desk and are powered on their own while mobile racks are simply powered by the PC PSU. Of course, doing that one has to be cautious because of ESD (sadly SeaShield is long gone), but that is not much different from handling bare optical discs, were you carefully have to avoid touching or scratching them, too. OTOH USB enclosures don't solve the most immediate danger while handling 3.5in HDDs: mechanical damage. The latter is the best reason to avoid them and buy robust 2.5in hard drives instead. Also those are bus-powered for a decade already.
  7. Best cloud backup hard drive?

    Of course not. Unlike building and selling a hard drive providing online server storage causes running costs. Just see it as marketing move by Microsoft to promote their OneDrive. Some day they will try to monetize it. To back up this drive, just get another one or two.
  8. I have been burned by the 840 Basic featuring TLC, also showing me, that Samsung's warranty promises are worthless. Pricing in Europe is unconvincing, compared to competitors products, they are all cheaper, even some of the MLC models. This series is best to avoid I think.
  9. Samsung 2TB SSD: when?

    My prediction was this would happen before 2020. Since this year I can order a 2 TB 2.5" 7mm flash drive for below 650 €. That's impressive (price-wise) and already on par with HDDs space-wise (the now available 4TB 2.5" HDDs are 15mm thick)
  10. My Samsung 840 (TLC flash) now has 4 (four) TBW after roughly 3 years and starts showing read speed degradation. Down from 530 to about 160 MB/s for older files (stored about a year ago). This lemon was the most expensive SSD i bought in 2013, two cheap and slow (IOPS) SanDisk G25s I bought along with it are still doing fine in linear throughput.
  11. For USB storage it means the device supports 16 byte commands (so these can be used instead of 10 byte commands, which are limited to 2 TB). Of course, you also need an OS which supports 16 byte commands itself, but it doesn't have to be a 64 bit OS. Something like Windows 7 x86 supports >2TB disks just fine. BTW: You can check for support even without having a drive >2TB available by simply checking if the 16 byte commands are implemented. The reason why you see those "tested capacities" in advertisements, because those resellers don't really have a clue what they sell. They order a container full of some USB gadgets from a Chinese OEM and then "test" what works with it. Fun fact: eSATA never had any capacity limits. I have still have old USB 2.0 docking stations, which work fine with 4 and 6 TB drives using the eSATA ports.
  12. These are as loud as you can expect it from 7200 rpm drives with 4 or 5 platters, but not louder than that nor exceptionally noisy. They are no super-silent drives either. The MD drives do a good job on fast seek times and that is something you can hear, too. I'm fine with that, YMMV. (Back in the old days, before the advent of patent trolls, we had AAM available to adjust that, but this is a thing of the past now.)
  13. Intenso is just reselling Toshiba MD drives in volume (or whatever cheapest drive they get their hands on). A price drop after listing a new model is nothing unusual. The first listings are usually a MSRP which will then be adjusted to a real price, once the distributor delivers actual drives. This is just a sign of a functioning market. For me it looks like the the two vendor oligopoly settled on rather high rates, while Toshiba with a low market share seems to do aggressive pricing for 3.5in drives. This is a good thing from a customer's perspective.
  14. Aren't SMR models sold as external drives already? Or does the Seagate STDT8000200 contain a different hard drive?
  15. It should be noted, that Samsung's warranty ist totally worthless.
  16. RRAM is also solid state memory. So there will be Solid State Drives (SSDs) with RRAM, if that stuff ever gets market-ready and proven in practice. Until then flash will have a nice time for at least a decade.
  17. Seagate ST3000DM001 - HD self test fails

    A failed self test is the definition of a dead drive, which needs to be replaced and repaired. Somewhere you have to draw the line. If a drive destroys data (as CHKDSK tells) it's defective.
  18. For what do you need APM support in a desktop drive? For linear transfers the WD40EZRX is on par with the MD04ACA400, proving that the WD drive has an higher areal density than the Toshiba. And while being quiet and slow on non-queued random seeks, it's performing well on queued accesses, depending on which benchmark you ask, even better than the Toshiba. Although, having it in an USB enclosure doesn't give you any benefits from command queuing, so for external use the MD would be the better choice.
  19. I recommend to buy a similar model from each vendor. Then test them yourself, put the winner into use and use the others for backup.
  20. Seagate ST3000DM001 - HD self test fails

    The drive is dead, back up your data and do a full erase with SeaTools as long as it's still detected. Then stop using it and sell it to people looking for a replacement PCB.
  21. It's a quite fast 7200 rpm drive, which delivers 120 IOPS for non-queued 512 byte accesses over the entire sector range, beating my 1 TB WD Blue drive. You can hear that actuator working, it has no acoustic management. If you are aiming for a silent drive, you could go with WD Green WD40EZRX, it's a 5400 rpm drive and it's seeking quietly. Of course, it does it's head-parking clicks, doesn't have APM support and has a built-in minimum limit for the spindown (standby) timer. Nor does anyone review recent optical drives. Smartphones and tablets seem to be more interesting for the tech review crowd.
  22. Does the drive support TRIM for throwing away data?
  23. 4K random accesses are quite costly on a floppy drive, because 4 KiB is almost half a track on a 1440 KiB floppy.
  24. Every so often I hear people say, that you must align partitions on SSDs, just as on advanced format hard drives, because "AS SSD" told them so. And people who heard that tell other people the story and so on. And we have created an urban legend. But is that really the case? All my SSDs (Samsung, SanDisk) tell me, that they use physical sector size of 512 bytes. They have a valid configuration word 106 (bit 14 is set) which bit 13 set to zero (1 = Device has multiple logical sectors per physical sector). So it's unlike the early WD AF models, which just had no valid word 106. The sector layout is completely abstracted from the underlying flash anyway, regardless of page size and erase block size, so there should be no read-modify-write cycles like on AF HDDs. SSD vendors don't tell people anything about alignment. So is that really an issue? Or just hearsay? We also have SSDs with controllers compressing data, so there can't be a real 4K-sector flash-page relation anyway. (Of course, you can align partitions preemptive "just to be safe", but that was not the question, I want factual data and clear examples of modern SSDs, which require alignment).
  25. In Europe the WD Black² is now at about €200, while the Crucial M500 240GB SSD is on sale for €90 and the HGST Travelstar 5K1000 1TB is now sold at €50 (everything incl. taxes). The M500 480GB at €180 is already slightly cheaper and the 960GB sold at €370 is almost at WD's original MSRP of €330 for the Black². As predicted the product got obsolete within less a year and may never return its development cost.
