  1. 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.

    Seagate Achieves 16TB HAMR HDD

    What platter count are they using? If they're doing 16TB with 8-9 platters, then HAMR is not improving density much. If they're doing 16TB with 5 platters, that would be very good.

    Toshiba L200

    Running good so far. During the drive swap, I discovered my notebook can apparently take a 12.5mm drive. But as all 3TB+ notebook drives are 15mm, this still does not make an upgrade possible. I thought someone had a 3TB out in 12.5mm, but apparently I misremembered. So back to the waiting game. Will SSD prices drop, or will someone intro a 3TB or 4TB drive first?

    Toshiba L200

    Defragging worked fine on the other partitions too. I defragged a partition on the old WD drive for comparison. The Toshiba was about 50% faster, which agrees with their sequential speeds. However, when the defrag finished up, it rebuilt/compacted the Catalog file, Attributes file, etc. On those files, it ran dramatically slower on the Toshiba L200. The disk activity graph showed a sawtooth pattern which might be typical of an SMR drive. I've avoided SMR, so I don't have a known one for comparison. First boot test: no abnormal delays. Quieter than the old drive.

    Toshiba L200

    Cloning completed. Speeds ran up to 140 MB/s, usually less as it was mostly copying from an older drive. Toshiba HDWL120 (revision JT000A) I've just defragged a bootable partition. Write speed was 10-30 MB/s most of the time, with occasional brief spikes. Both below and above that range. This is the speeds I expect when defragging a 2.5" PMR drive. Proceeding with defragging other partitions. Edit: it was a defrag+optimize. All files on the volume get moved, often twice.

    Toshiba L200

    I'm in the process of cloning partitions from my old drive to the new L200. I'll watch for SMR clues, but this may take awhile. The old drive was indeed failing. Disk Utility still thinks the SMART status is ok, but I'm getting I/O errors during cloning.

    Toshiba L200

    My 2TB L200 has not yet arrived, so I haven't been able to comment. It will be installed in my Macbook Pro, so I'll watch for your thermal pauses. The notebook already has a 2TB Samsung M9T (replacing the optical drive) for the last few years. I have not observed any pauses there, or any other odd behavior. It's a 3-platter, and I think I benched it once at around 62 MB/s sustained write. So about half the speed of an L200.
  9. I've never dismissed it, that may be the problem. I suggest a more minimal edit: could you set it to appear only when the cursor leaves the page? So it does not appear when mousing around story links, and getting familiar with SR's content.

    Any word of new 2.5 drives above 2 TB?

    Unfortunately they outwaited me. The drive I wanted to upgrade has been showing increasing hesitations. I ordered a Toshiba 2TB, as nothing better was available. 3TB should be out now, with 4TB on the horizon.

    (in reply about a deleted spam post) He's a spammer. Don't worry about what he says, and keep a tight grip on your wallet.
  12. OK, not an ad. Upon closer look, it's an email newsletter signup. Which pops up whenever your cursor leaves the page, or moves a significant amount on it. Like towards another tab, or towards a story link on the page itself. Once it pops up, it dims the rest of the page, and covers it. Clicking on links does not work until/unless you dismiss the popup. I captured the form submission code for reference: form action="//mc.us10.list-manage.com/subscribe/form-post?u=047b32e7f58e3630278c76a7f&id=9faf3094f5&popup=true" accept-charset="UTF-8" method="post" enctype="multipart/form-data" data-dojo-attach-point="formNode" novalidate="" Firefox 52.9.0 ESR / macOS 10.14.0 (also tested in Safari, Chrome, Opera with same result) Edit: it appears on the SR story page too. At least the page can be scrolled under it, and read around the banner. Personally, I try not to click on popups, because it can lead to unexpected results.
  13. Something wrong with the story link. I'm trying to access the story from here, because the pop-up thing on the front page happens before I can click on a story link there. I know ad rates are terrible today. But that front-page popup is majorly annoying.

    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.

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