  1. I see there have been no forum comment threads for news posts since Nov 19. When I followed a comment link, it took me to reddit. Which I've never signed up with. Is SR discontinuing the forum here? I notice a lot of spam lately, even after I reported one. Spam still up days later. I actually wanted to comment on the Seagate dual-actuator story. They talk about HAMR, release it to trusted partners for testing ... and we hear nothing more. No public release. They talk about dual-actuator, now released to trusted partners for testing ... and no word on public availability. The future seems to be putting up a fight about becoming the present. Are the HAMR drives experiencing issues in testing? That would explain why they haven't shipped yet.
  2. linuxbuild, you do realize this thread is from 2014? It's doubtful any drive mentioned above is still manufactured today. Your link post in the other (current) thread suffices.

    Hard drive errors, time to get a new one?

    You can use WikiPedia's key to SMART values. 1) Read Error Rate = vendor specific value. Desired to be "low", but that's all we know. Interpreting it would vary by manufacturer. 7) Seek Error Rate = another vendor specific value. We don't even know if high or low values are desired. 184) End-to-End error = desired to be low. This attribute may predict drive failure. The last one is the only one I'd worry about. On top of that, you're getting recurring disk errors. I'd replace the drive. You're backed up, right? In case the drive fails unexpectedly?

    New BackBlaze Stats

    For anyone interested, BackBlaze has posted new HD stats. Their HD Summary for 2018. Highlights: • They've deployed 1,205 Toshiba 14TB drives. Annualized failure rate projected at 3%, normal for initial burn-in. They've been in service one quarter, with actual failure rate of 0.75% so far. Annual figure expected to decline going forward. Depending on how good a price they got per drive, they may have paid over $500K for the set. • They've deployed a heck of a lot of Seagate 12TB drives. 31,146 with annual failure rate projected at 1.39%. Once again, they've been in service less than a year on average. So this is probably mostly burn-in losses. Probably spent at least $10M buying them all. • No mention of the new Toshiba 16TB drives. Which I have not seen for sale anywhere. • HGST has the best reliability again by small margins. Seagate's figures continue to improve with later models. WD is dropping off the chart as older models are retired - BB is not adding any new WDs.
  5. The only diff between generic- and Mac-friendly drives is how they're preformatted. Mac drives come formatted HFS+ (Mac OS Extended - Journaled). PC drives come formatted NTFS or ExFAT. Just reformat as needed - it's the same drive either way. Why do you need data recovery of your backup drive? Unless your main drive(s) have failed, your backup is just a backup. Swap the drive with WD, plug the new drive in, reformat as needed, and let Time Machine start over. ps - you contacted Apple Support. You didn't contact MAC - no such party.
  6. As you're only using 250 - yes, you can use a 480-512 GB SSD. If your data is growing slowly, then a ~500 will hold you until SSD prices are better.
  7. Did you open it up, to look over the real drive inside? Either WD has begun making 2.5" 5TB drives ... or they swallowed their pride and bought drives from Seagate. Finding a Seagate drive inside a WD external - now that would be a front-page story.
  8. As 16TB drives already require 9 platters, a conventional 18 needs 12.5% higher overall density. Or about 6% linear density increase AND 6% tracks increase. Are these the first MAMR drives? We keep getting promised HAMR and MAMR drives any time, and that further increases are not possible without. Only to keep getting conventional size increases. This isn't exactly a complaint, but they should keep their stories straight.

    Toshiba L200

    I do not recall this being announced. Newegg shows stock available today. Toshiba has a new 2.5" / 7-9.5 mm lineup out, in 2 TB / 1 TB / 500 GB. Apparently all 5400 RPM. L200 in 2TB (9.5mm) for $95 My question is if it's PMR. Toshiba's product page has no detailed specs. (click on the L200 pic in the banner). Their support section lists the drive, but basically has no documents. Obviously I'd like to see a notebook drive bigger than 2TB. But even at 2TB, it would be nice to have a current PMR available. The M9T is running $156-200 on Newegg (about half of a basic 2TB SSD), and I'm not certain it's still being made. Any chance Storage Review could use their spies to determine if it's PMR?
  10. All the comparison drives were other Seagates, in 14 or 16 TB. Perhaps some HGST, WD, and Toshiba 14s for comparison? Any update on the Toshiba 16 TB? It was announced months sooner, but I've yet to see it anywhere.

    HDD and slow sectors

    No reallocated sectors. Very low start counts and run time. Low max temp. I'd chalk it up to driver or firmware hiccup every 28 GB or so. If your backup data is critical, change drives. Otherwise, I'd pay attention to it in the future, for any misbehavior.

    HDD and slow sectors

    Can you dump and post the SMART data for your drive? If it really is reallocated sectors, that would be parameter 05. Seems the most likely, but it could also be a few other things. Like a poor cable, or internal problems. If it's your only backup, and the data is critical, I'd be concerned. But I'd like to see the SMART data rather than guesswork based on a performance benchmark.

    HDD and slow sectors

    That curve looks normal to me.
  14. Are these the first HAMR drives? Also, is it really the first shipping 16TB drive? Toshiba announced a 16TB conventional (non-HAMR) months ago, without a shipping date.

    2,5" 2TB HDD

    That's not quite accurate. HGST did not sell their entire 3.5" business to Toshiba. Only enough to allow Toshiba to immediately enter the consumer market as a real competitor. HGST retained plenty of 3.5" assets, and continued to sell them. With newer models introduced for years.

    2,5" 2TB HDD

    This one is a 3.5" drive.

    2,5" 2TB HDD

    I have both the Samsung M9T and Toshiba L200 2TB drives installed. The L200 is a good bit faster in my benchmarking. Never been certain if it is SMR. M9T has been in service for 3+ years. L200 for about 6 months. No issues with either.

    Micron 1300 SSD Announced

    No prices available, not even MSRPs? Do they give availability, so we can check when it hits newegg, etc? Flash is way overdue for a price war in my opinion. Be nice if someone finally kicks it off.
  19. I updated my pw, so the thieves cannot log in and reduce the average quality of my postings. Those viagra posts would really cut into my rep. However, I had to change my pw over HTTP. SR has an HTTPS cert, but it's only valid for the news side. And using it with a forum address loads the news side anyway. Perhaps the SR cert(s) could be updated, so the forums will load securely?
  20. It's been a week. Does it look like we're out of the woods?
  21. I did not get this email, or any other from SR in the last 48 hours. Checked my trash & spam folders to be sure. My email addy with the board is valid. Perhaps SR interrupted outgoing mails before it got to mine. Advice from an admin on an unrelated board: they want to download the user table. Preferably via SQL access, makes it easier and faster. They want the hashed passwords, salts, and email addresses. Over time they can crack the hashes, making the dump much more valuable than emails alone. They may also be interested in the private message table, in case any users exchanged email addresses. Hope everyone uses unique random passes on every site. That's the way to go. Once SR is sure they're clean, I'll update mine.
  22. Thinking about this, it puts pressure on Seagate to intro HAMR at 20TB. That, or release 16TB HAMR below Toshiba's price. Toshiba not only scooped Seagate on size, they got to market faster. Seagate will have to give consumers a reason to switch.
  23. I did not expect this. Figured 16TB would require HAMR or MAMR. With it still at 9 platters, I wonder how they squeezed in the extra density. Without going to the dark side (SMR).
  24. I like that Toshiba (and HGST) routinely make 7200 RPM drives. While WD and Seagate push out 5400/5900 - then try to conceal it by withholding the RPM spec. I've had to adopt the rule that if it doesn't say "7200" on the drive (or box), it's a slower drive. Marketing shouldn't be in charge of printed specifications.

    Seagate Achieves 16TB HAMR HDD

    Using the chart from the roadmap and their achieved "2 Tbpsi areal density" suggests the 16TB is using 8 platters. They're probably aiming for 20TB using 8 platters also. 9-platter drives must be packed solid inside, so using 8 makes more sense. Leaves space for the extra laser components of each head. Corollary: the flagship drive size will probably use 8 platters for the foreseeable future. As this will push mid-sized drives (currently 8-10 TB) back down to 3-4 platters, it will lead to lower prices for mid-sized drives. So we can finally return to annual drops in price-per-gig. Not as good as I'd hoped for on density increases yet, but most definitely good news.
