    What to do with 8 new FC Drives

    Yes, eBay. Don't try for a swap, you'll wait too long for someone with the right combination. Sell them, buy what you need.

    What to do with 8 new FC Drives

    Can you return the drives? Especially for an exchange if the store also sells SAS?

    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?
  4. It's been a couple years since we reached 2TB in the 2.5"/9.5mm form factor. I know there's a Toshiba 3TB, and a Seagate SMR 4TB, both in 15mm. Both have been out for over a year. I take my video library with me on vacations, so capacity is more important than speed. Any rumors of 9.5mm drives coming that are bigger than 2 TB?

    Toshiba L200

    Just visited Newegg for something else. Random observation: When the 2TB Toshiba L200 first hit at $90, M9T prices on Newegg were $156-200. Today, about a month later. The L200 is still at $90. All the other 2TB drives (7-9.5mm, including the M9T) have dropped to $90 or below. The benefits of competition.

    Samsung 860DCT SSD Review Discussion

    I brought this up here a short time ago. SR needs to link these graphs to an explanation page, or people are going to keep asking. They're testing loads at successive % of capacity (0% - 120%) for each drive on a third axis (not shown). Then measuring both X and Y values. At any given test point, there is only one measurement. For each drive, the graph gets weird when they hit 100% of their capacity. Flatter, more-natural curves are typical of higher-performance drives.
  7. Thanks, that makes sense. As opposed to people not noticing a glitch for 8 months. I couldn't picture how you'd get such graphs by setting either axis, then measuring the other. You're actually setting values on a 3rd axis (% of capacity) then measuring both X and Y.
  8. It's not just this review. I started checking older reviews in Firefox, Safari, Chrome, and Opera. It's the graphs, not the browsers. Here's a typical one: My personal favorite, resembling kindergarten scribbles: Am I the only person who noticed the corruption? Checking reviews, it began happening around January 2018. Dec 22, 2017. Crucial MX500 1TB review. Graph is clean. Jan 10, 2018. Crucial MX500 500GB review. Corruption present. It appears the graph data avoids an elliptical region in the upper right corner. But the ellipse size and proportions vary by graph.
  9. How did you get the impossible graphs? Graphs #2, 4, 5, 6, 7 require multiple measured values for some levels of IOPs or throughput. Assuming you threw IOPs at it, and measured the latency. There's some minor glitching in the comparison drives too. But the 660p is the main culprit, with squiggly plots.
  10. It looks like we'll be getting some long-term reliability stats on Toshiba 14TBs as well. BackBlaze is buying 1,200 for deployment. From their Q2 2018 stats: StorageReview does different tests, so we're going to have a broad data set on the 9-platter design. I'm looking forward to the SR review. If the drives are good enough, they may force Seagate to start shipping HAMR models.

    Toshiba L200

    The key concern is SSD price. If SSD prices crashed, I'd completely lose interest in HDDs. But SSDs remained stubbornly high for several years, then resumed a slow downward creep. Since SSDs don't drop despite repeated process improvements and new factories opening, the only near-term hope is larger HDDs. At least those have to be competitively priced to sell vs SSDs. So upgrade choices are: (A) no upgrade, keep waiting. (B) 4TB SSD for $1000+. (C) potential 3TB HDD in the $120--140 range. I've been stuck at (A) for around 4 years now, because I'm not willing to be ripped off with (B). In my experience, most people do not like to be ripped off. That leaves denser HDDs as the only realistic hope.

    Toshiba L200

    The sizes offered imply it's a 2-platter drive. Which would be inline with current platter densities. If it is PMR, it would be a solid improvement over the M9T (3 platters). Since Toshiba offers that (3.5") 14TB PMR drive with a crazy 9 platters, it opens the door to a 3-platter 3TB in the near future. Maybe we'll finally get some upgrade options before SSDs take over the space.

    Any word of new 2.5 drives above 2 TB?

    The annual tradition resumes. I'm approaching a vacation, and looking to upgrade my laptop. Newegg lists: 2TB HDDs (reported to be SMR): $80-94 2TB M9T (PMR): $157-200 (now 4+ years since introduction) 2TB SSD: $314 4TB SSD: $1,100 With SSD prices falling and the M9T going up, they could pass each other in a year. If they do before <= 9.5mm 3/4TB HDDs are introduced, then SSDs will exterminate all laptop HDDs. Permanent loss of a market. External 2.5s will last a bit longer. I hope the HDD makers are pleased. I'm certainly not.
  14. The V300 comes in 1-3 TB @5940 RPM. Is this a 2.5" drive? If so, what thickness, especially on the 3TB? We're long overdue for a 3TB in 7-9.5mm form factor. I tried the Toshiba link for more info, but it goes to their memory section. Flash products, and no hard drives.

    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?
  16. 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.
  18. The world goes hungry, but at least we have bigger cards?
  19. 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.
  22. 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.
  24. 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?
  25. I doubt you'll get that kind of answer from seagate_surfer - I believe he/she is a Seagate employee handling social media.
