  1. Seagate Announces 14TB Helium HDD

    14TB and Helium. Sounds good, but all the other important specs are missing. Also missing on the pictured label - they should be in the blank space below the barcode. RPM? Cache? Sustained sequential transfer speed? Platter count? PMR/SMR/host-managed SMR? MTBF?
  2. 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.
  3. 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.
  4. The world goes hungry, but at least we have bigger cards?
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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?
  11. I doubt you'll get that kind of answer from seagate_surfer - I believe he/she is a Seagate employee handling social media.
  12. 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.
  13. 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.
  14. 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.
  15. 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.
