  1. 1) An adapter cannot increase the bay height in your notebook. Drives up to 9.5mm only. Plenty of people are waiting for 3TB in 9.5mm, but they're not in a hurry to release one. 2) Not that I'm aware of. SATA is a standard, it should just work. 3) There are no 7200 RPM notebook drives above 1TB. 3a) You didn't list the three drives. 3b) The Samsung M9T - that warning is one person's experience with it. I've had that exact drive in my MacBookPro for 3+ years without a single issue.

    Any word of new 2.5 drives above 2 TB?

    We're badly overdue. If memory serves, the top 2.5" used to be around 50% the capacity of the top 3.5". That's before 3.5s went to high platter counts. Still, 3TB should be out. The only good news I've seen is in SSDs. After a 3-year stall, there's finally some price movement. Baby steps though, nothing dramatic yet. 2TB and 4TB have dipped below their 2015 prices, everything smaller is still above 2015.
  3. The world goes hungry, but at least we have bigger cards?
  4. Steined may mean extended use of a drive while it's 95% full or higher. For a boot drive, I want to stay below 80% full. Going higher will cause severe file (and free space) fragmentation, and force a workout upon the heads to read/write files. This might shorten the life of the drive. It will certainly slow things down. For a drive in storage (file archiving for example) it doesn't matter how full it is. Go up to 99% if you like. For a media drive (mostly read from, few writes), I'm OK with 90% full. For a regular working drive, I use the same 80% rule as for a boot drive. Go above 80%, clear it down or buy a bigger drive.

    14TB performance reviews

    If I've read correctly, there are three 14TB drives. But I don't think any are shipping. Maybe sampling to OEM partners, but ebay and the usual stores have zip. HGST: 14TB SMR drive - Hs14. Toshiba: 14TB conventional drive - MG07ACA series. Seagate: plans to introduce a 14TB SMR drive, but hasn't announced it yet? I could swear this got mentioned somewhere, but can't find a link.

    SSD Currently unreadable (pending) sectors

    Does CentOS 7.4 support the TRIM command? I couldn't find that data on Wikipedia - the TRIM page doesn't mention CentOS among the supporting OSes, and the CentOS page doesn't mention TRIM. If it were running without TRIM, the SSD would be preserving lots of deleted files. And you'd presently see delays while it preps pending sectors for writing. Which would go away once the SSD's housecleaning caught up. If this were the case, you could briefly run each SSD on a system supporting TRIM and your filesystem, to clear all the free blocks. Or change out your SSDs for larger ones, with far more free blocks to buffer you against the problem. Or of course, bug the CentOS devs to add TRIM support.
  7. I wish you were. I'm so tired of waiting for the price drop curve to reassert, which will unlock size increases. And HDDs could use the renewed price competition. An actual 500 TB SSD would cost $100K to $150K today. Kudos if you really scored one for testing. And feel free to send it my way afterwards for, er, extended use testing.

    Samsung HDD fails at 2 hours use

    I hope you have a backup. If you don't, buy an external HD IMMEDIATELY, and back up. If need be, copy for an hour at a time, then shut down for an hour. Repeat as needed until all your data is backed up. Get a new drive. Install OS as needed, copy all of your data onto it. Restore from your backup, or from the old drive an hour at a time. Everything copied across, as well as backed up on the external? Good. Disconnect the suspect drive and run from the new drive for awhile. If the symptoms all go away, you'll know the old drive was at fault. Dispose of it in a humane fashion. Or violence can be therapeutic ... If the symptoms do not go away, there's something else wrong with your computer. That is a separate diagnostic, but at least your data is safe.
  9. The HDD makers do aggressive patent licensing with each other. I think HGST came up with the first reliable helium seal design, and WD is selling some rebadged HGST models. About the article, could you change "disk" to "platter"? "Disk" usually refers to the whole device - I've never before heard platters referred to as disks. So they're up to the MG07 series, and leaped ahead to 14 TB in a performance drive. It sounds great, but I have yet to see the MG06 series (up to 10 TB) for sale anywhere. Even when I search by model number, all I find is the news announcements. Has anyone seen one in the wild?
  10. I doubt you'll get that kind of answer from seagate_surfer - I believe he/she is a Seagate employee handling social media.
  11. There have been plenty of SSD announcements. Few draw comments. What would really draw excitement is price drops. If storage began dropping in price again, then bigger models would become economic to announce as well. As it is, I've found new model announcements a yawn. They're marginally better than existing models, at the same prices. No motivation to upgrade. Any word on the global flash shortage? Any sign of imminent easing, and a resumption of the price-drop curve? They must have been building new factories for the past couple years, and those must come online eventually.

    Affordable 10TB drives availability?

    B&H recently had an HGST 10TB on sale for $299, but it's back to $319. It's not your imagination, HDD prices have been stuck for a couple years now. Hanging a little above $30 per TB - more for premium models. Larger drives have been introduced, but unlike in the past, they aren't a better deal. They just cost more. And existing sizes don't drop in price. I've been holding off upgrading myself for two years now, waiting for a correction. There are technical reasons why bigger drives are harder to do today. But that doesn't explain why existing sizes fail to drop. I believe it has more to do with reduced competition. There are only 3 real competitors today (WD, Seagate, Toshiba) as HGST is wholly owned by WD. SSDs were putting pressure on the smaller HDDs, but flash demand went through the roof, and SSD prices stopped declining ... 2 years ago. They've even climbed by about a third since - we're in a global flash memory shortage. So nearly all the competitive pressure vanished, and HDD value stopped improving. Draw your own conclusions. As to deals, the 8TBs are showing signs of improvement. Limiting things to 7200 RPM drives, you can get 8TBs on ebay for as low as $200 ($25 per TB). You can improve things a little further if you buy 5400/5900 RPM or an SMR drive. These drives may not have a manufacturer warranty though, as they may be grey market (imported from Europe/Asia) or shucked from externals. I won't touch SMR myself, you can't use it in RAID. Or swap it in as a system drive. It's limited to whatever you bought it for, and cannot be retasked during a later upgrade. So it becomes a disposable purchase. The 5400/5900 drives are better, they can be RAIDed to stretch their lives if HDD prices remain high. But they still tie your hands somewhat, by being poor system drive choices. My advice. Hold off as long as you can, buy as little as you can, until prices correct. I'm hoping for movement this Black Friday. If not, the SSD market will slowly correct as more capacity comes online. And Toshiba (newest guy on the block) is slowly gaining market share. Eventually they'll all have to stop taking profits and compete.

    SonicWall NSA 2650 Review Discussion

    The 2nd and 3rd links require registration. Real name, email, company. The 2nd one additionally wants phone number and postal code. I'll give those a pass. Based on the 1st infographic, they're installing a custom SSL/TLS certificate on the end-user's computer, then performing a man-in-the-middle attack. When the user opens an https connection, they're only opening one to the firewall router. The router opens the real https connection to the server. Decodes all the traffic both ways, checks for malware (and anything else the sysadmin dislikes) then re-encrypts remaining content and sends it along. There's no mention of banking, government, or other classes of sites being off-limits to the attack. Based on the infographic, ALL secure connections are intercepted for filtering and analysis. I can see this for a business serving employees. I'd consider it dubious for home use serving family members. And totally unacceptable for use by a library, hotel, or restaurant. Or most especially, by an ISP. It makes a mockery of the padlock icon, which is supposed to mean you have a private connection to a server. With only the sender and recipient privy to the contents.

    SonicWall NSA 2650 Review Discussion

    How is it doing Deep Packet Inspection of SSL connections? Is it using a zero-day to decrypt the packets? Or is it impersonating the websites connected to using cloned security certs? Unless I'm missing something, the article describes a successful Man-in-the-Middle attack, breaking current internet security, as though it were a routine feature.

    12TB performance reviews?

    Would you accept a 12TB BarraCuda Pro review? They don't claim it to be an enterprise-class, but it's expensive enough to qualify. $500+ on newegg.
  16. It can't be impossible - Seagate plans to ship HAMR samples to their customers (I think this means OEM partners) this year, with product hitting the general market in 2018 or 2019.
  17. HAMR and MAMR can't come fast enough. I'm not impressed with SMR, and both these techniques eliminate SMR. It doesn't matter if the magnetic field spreads out, since it only flips bits where the laser or microwave beams fall. However, WD's projection of only 40TB by 2025 isn't very impressive. 8 years to triple capacity?

    Largest 2.5" 12.5mm PMR drive?

    The M9T is 9.5mm, which shouldn't be a problem. I've had one in my laptop for a couple years now. It's been trouble-free. note: the M9T has also been sold under the Seagate label, though the model number usually still has "M9T" somewhere in the text. Might give you more options to find better prices.

    Largest 2.5" 12.5mm PMR drive?

    Everything 2+TB is in the 15mm size. I'm waiting for 2+ in the 9.5mm size, so far no dice. It's like they're waiting for SSD prices to fall enough. Then concede the 2.5" market.
  20. Beware that it's SMR, even though they're calling it an enterprise HDD. Hs14, not He14.
  21. What kind of drive is it? SATA drives can't do a real low-level reformat the way SCSI can. But they can report error codes via SMART.
  22. It's good to see Toshiba join the 10TB club. As WDs helium drives appear to be rebranded HGSTs, there were only two competitors before. Now if only Toshiba can get the drives out soonish. Their 8TBs took a couple months to reach the public. I'm due for a backup array upgrade, so hopefully the 10s can reach market by Black Friday.

    New datagrave needed

    I've run five Toshiba MD04ACA500's for a couple years now (5TB) without a single failure. They weren't even bought bare, I harvested them from external enclosures.
  24. I assume the proliferation of higher bay counts (and growing popularity of RAID solutions) is caused by hard drive sizes not growing fast enough. Over the last decade, storage has hit several stalls. But data needs have continued to grow, especially with higher video resolutions. The consolidation of HDD manufacturers down to 3 didn't help. The need for 2-stage positioning motors for higher track counts. Took 2 years to solve, though the introduction of PMR halfway through reduced the pain. The 7200.11 fiasco. Afterwards everyone went super-cautious on new model introductions. Because they didn't want to make the same mistake. This also caused the proliferation of 5400/5900 RPM drives, when they had been going extinct in the 3.5" size. The Malaysian floods. Plus the jacked prices after the floods, which the manufacturers liked so much, they foot-dragged on restoring production volume. Result: instead of taking their predicted 6-months to return to normal, it took 2 years before prices returned to pre-flood levels. Their financials showed excellent results over this period. The current state, where they introduce bigger drives again. Without cutting the prices on existing sizes. So you can buy bigger or existing sizes, but your price-per-TB hardly budges. Competition from SSDs would help. But they've been in their own stall for almost two years now. Bigger sizes are introduced, but demand has grown rapidly. You'd think new flash factories would come online fast enough to relieve the pressure. I've been waiting two years to upgrade, but the price stalls on HDDs and SSDs have caused me to hold off. I'm still waiting for a correction to hit.
  25. BackBlaze has posted their Q2 2017 Hard Drive Reliability stats. 83,151 drives this time. Not a lot of surprises. HGST still comes out on top, while Seagate has some problems with their 4TB models. The 8TB models look good regardless of manufacturer. Biggest surprise for me: BackBlaze has begun deployment of 12TB drives, and in decent quantity too. They don't say what model(s). HGST and Seagate both have 12TB drives shipping, so either is a safe bet. To my knowledge WD hasn't announced anything past 10TB, while Toshiba has just gotten their 8TB models shipping in quantity.
