  1. Why would the 4, 6, and 8TB be done via dual drives today? Single-drive solutions would be quieter, cooler, and far cheaper for those sizes.
  2. From retail drive pictures, the WD Gold appear to be rebranded HGST He drives.
  3. HGST does have a 12TB enterprise drive out, currently running $630 on ebay. I've yet to see it in the regular channels. Look for HGST He12 If you are looking for large economical storage, drives in the 6-8 TB range are approaching half the price-per-TB of that He12. A RAID array in a NAS would get you more storage, and probably at a lower price. Admittedly with more noise.
  4. You posted your thread in the right place.
  5. I find myself in agreement.
  6. 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?
  7. It's been 15 months now, still no sign of a 3 TB drive in 9.5mm. Unless I want to drop $1500 on a 4TB SSD. I didn't think it would take this long for an upgrade to appear. Larger drives used to appear like clockwork.
  8. 16 levels of analog voltage per cell. It better have amazing error check and correction. I won't be the first one to try this. Side note, between higher bits-per-cell and 3D layouts, the bits-per-chip has gone up dramatically. I was expecting SSD prices to decline dramatically as density goes up. But they've stayed about the same (or even increased slightly) over the past year. What gives? The manufacturers can't all be in a conspiracy to prop up prices, can they?
  9. Any special reason why you're commenting on a 3-year-old article? You do realize some of these models most likely aren't made any more? SSDs are evolving quickly - models rarely stay on the market for years. Also, prices have come down. Who is going to consider a 200 GB drive for 870 EU when you can buy a (slower SATA-III) 2 TB SSD for $550 today?
  10. BackBlaze makes their raw data file available for download. You should be able to extract that data with a bit of scripting.
  11. According to the specs sheet downloadable from here, the IronWolf NAS 10TB is 7200 RPM. 4TB and smaller are 5900 RPM. Performance plateaus at 210 MB/s sustained for 7-10TB. It could be a limitation of the controller. I'd still be interested in a direct measurement. If the RPM were 5900 after all ... now there would be a story. Of course, SR might have trouble getting Seagate samples for awhile if you happened to break such a hypothetical story ...
  12. Interesting comparison. Toshiba 8TB, 7200 RPM WD Red 10TB, 5400 RPM Seagate IW 10TB, 7200 RPM I can see why the Toshiba would generally outperform the WD - higher RPM is overcoming the size difference. The more puzzling aspect is why the Toshiba edged out the IronWolf. Seagate's drive is the same RPM as well as larger. At least according to the specs. Did you run an acoustic check on the Seagate for primary frequency, or do a rotational latency check, to measure the actual RPM? If the Seagate were at 5900 RPM, the results would make a lot more sense. btw - this story gives the WD Red as 7200 RPM. But the actual Red review gives it as 5400.
  13. The HGST 12TB drives have appeared on eBay. US seller. Going around $700 each.
  14. There are only 4 brands making 3.5" drives today, so "top 3" is probably not useful. Here they are, more-or-less in order of reliability based on recent BackBlaze stats. HGST (owned by WD, consistently highest reliability) Toshiba (small BackBlaze pool, so stats show higher variability) Seagate (2nd largest, seems to have upped their quality the last couple years) Western Digital (largest one, seems to have become less attentive to quality lately)
  15. I read daily. Mostly reply on HD news, which isn't as frequent as we'd like. Bring on HAMR.
  16. The 03 or 04 part is the series number, it gives an indication of density and possibly power efficiency. Toshiba's 05 series has just hit the markets, with 04 still going strong. 03 is an older design today. I don't know what the G or D stands for.
  17. If it's software RAID, you're all good. The hardware will see the drives as individuals. I've seen Raptors used in softraid before. Assuming it isn't software RAID, what controller are you using?
  18. OK, found a Toshiba 8TB for sale. Actual picture, and the listing claims 7 already sold. http://www.ebay.com/itm/371841480025 However, it's an MG05ACA800E enterprise drive. I don't recall anyone announcing this drive. The 8TB MN announced in this story is the MN05ACA800. Did Toshiba ship the MG 8TB without an announcement?
  19. It's about time. They were stuck at 6TB while everyone else has 10 and HGST has announced (but not shipped) 12TB. The specs and other materials do not identify the platter counts. Bottom screw locations imply the 6 and 8 use at least six platters each. Any word on availability?
  20. I detect a lawsuit happening. WD's SanDisk Skyhawk sounds a lot like Seagate's SkyHawk Surveillance drives. Which hit the market a good while earlier. Edit: I see that great minds think alike.
  21. For a 500 GB drive I would not bother. Even in 2.5", sizes top out at 5 TB and SSDs are slowly exterminating the 500 size.
  22. Apple waits until they're 7 years old - product support laws in California. You're supported until early 2018. Even then, later OSes won't deliberately break. Apple just won't test them on your machine before release.
  23. I've developed the impression all inexpensive Seagate 8TB drives are SMR. They're cagey about it - I pulled the data sheet on the 8TB Backup Plus above. It didn't give away if it was SMR or PMR.
  24. Article typo: Spindle Speed (RPM): 200
