    WD Caviar Black 2TB Review

    Thanks for the review, and the revitalized SR site! Given that you have the WD RE4 2TB enterprise drive in the comparison, I assume we'll be seeing its own review article shortly? I'm leaning towards getting the RE4 2TB drives for a new QNAP or Synology RAID NAS, considering the RE4's TLER, higher MTBF, shock/vibration sensors, etc. It's surprising to see the WD drives surpassing Seagate in most of the benchmarks. I seem to recall years ago that the WD drives at the time had excelled in desktop usage, but were bested by Seagate in multi-user server scenarios... But it's also interesting that your real-world HTPC test found the Seagate Constellation ES 2TB much closer to parity with the WD RE4 (and beating the WD Caviar Black). I wonder if your other Storagemark 2010 real-world tests will also find that the Seagate performs better than synthetic benchmarks would suggest? Anyways, can you clarify whether the WD Caviar Black 2TB supports NCQ (just like the WD RE4 and Seagate drives)? WD's Sep 2009 press release mentions that the RE4 2TB supports NCQ whereas the Caviar Black 2TB does not (see the section titled "Additional Features for WD RE4 2 TB Enterprise Hard Drives"). But another site seems to think that NCQ is supported (and really, at this point in time I would've expected all new hard drives to have it).

    Rumored WDC 20k RPM HDD

    I don't remember where, but I recently read an interview with some WD product manager, who commented on this rumor. He basically said there's no possible way WD or anyone else can produce a 20,000 RPM drive in the feasible future, as the obstacles just can't be surmounted...
  3. That's a good idea... MaximumPC's benchmarks of the Caviar Black are not promising at all (generally slower than SpinPoint F1) http://www.maximumpc.com/article/western_d...al_caviar_black

    6*SDHC SDD

    Who knows maybe there are SDHC/microSDHC cards with sustained speed higher than 6MB/sec. I've seen 300x (UDMA) Compact Flash cards with minimum sustained speed of 45MB/sec...

    6*SDHC SDD

    Interesting solution for a 2.5" SATA HDD formfactor. I wonder how much this PhotoFast adapter will cost in the US? I can buy 16GB SDHC Class 6 cards for just over 50 bucks each, yielding 16GB x 6 = 96GB. SanDisk's new 32GB SDHC Class 4 card currently costs $130 (not sure about Panasonic's 32GB Class 6 and Toshiba's 32GB cards), but should come down over time, yielding 32GB x 6 - 192GB. In contrast, there are already 500GB 2.5" HDDs, and Toshiba will release a 160GB 1.8" HDD... Unfortunately the PhotoFast specs are displayed as a Flash image so Google Translate doesn't work. But I see snippets such as: - RAID 0 - 130MB/sec - 130MB ... 85MB - MLC ... SDHC ... 60MB - SDHC(4GB-32GB) - SATA1.5/3Gbps - 5V/150mA I have two concerns with using this as a SATA boot drive. First, I'm not sure how reliable this 6-card RAID 0 solution will be as a primary drive. Not withstanding the reliability of the controller/adapter itself (?), I'm not sure that SD cards are tuned the way SSD drives are (regarding wear leveling, for example). So striping 6 of these cards together could be risky? Second, SDHC speed ratings only go to Class 6 (meaning a minimum sustained speed of 6MB/sec). Cards often advertise a higher (maximum) speed such as 20MB/sec, but I would like to find an SDHC card with a guaranteed sustained speed higher than Class 6. Heck I don't understand why flash cards even have different minimum/maximum speeds, since they don't have a moving platter to contend with different inner/outer track speeds. I mean, that's why flash storage has negligible access latency in the first place (don't need to seek on a moving platter), right? Then again, I suppose RAID 0 could substantially increase the (sequential) sustained read/write above that of a single SDHC card? Anyways, I would prefer to use something like this as an external drive. I know I can insert this PhotoFast SATA product inside a 2.5" USB drive casing, but that seems unnecessarily convoluted... I'd like a small (around 1.8" formfactor size) USB (or USB/eSATA combo) enclosure that also takes 4 to 6 SDHC or microSDHC cards concatenated in some way. That's because I do appreciate the flash benefits: low power (single USB port sufficient), vibration/shock proof, silent, negligible access latency, etc. For microSDHC, I can buy 8GB Class 4 cards for 40-50 bucks. SanDisk's new 8GB Class 6 card started out at $100 but is now already down to $60-70. SanDisk's 16GB Class 4 card was supposed to be out by June, but it'll probably cost a lot.
  6. StorageReview post The Caviar Black does sound interesting though, can't wait for the review and actual street prices. As posted elsewhere:
  7. It's not just the 15mm enterprise height of the VelociRaptor that prevents normal usage in a laptop or USB enclosure. It's also the power requirement, as the SR and TR reviews mention. So even if I find a 2.5" HDD USB enclosure that fits the VelociRaptor, it would have to use its own 5V/12V AC adapter instead of being (dual) USB bus-powered?

    USB flash drive recommendation

    I'm looking to buy large capacity USB flash drives that are more affordable (a few hundred dollars max) than putting an SSD in a USB enclosure. Blistering speed as well as a dual-mode USB/eSATA interface would be nice but are not mandatory. A solution using standard SD or microSD cards would be great though, which I could re-use in digital cameras, phones, etc. I also want something as small as possible physically. Long ago I carried a 1.8" Travelstar 60GB IDE HDD in a thin and small aluminum enclosure (which never needed more than a single USB port for power). I'm now looking for an even smaller package that has a larger capacity and uses more rugged flash media. I've been looking for: - 64GB (or larger) USB flash drives - 32GB Class 6 SDHC cards - 16GB Class 6 microSDHC cards Actually I'd really like a USB enclosure that takes multiple SD or microSD cards at once (and preferrably able to span/JBOD them into one logical volume). Like those pocket USB SD/microSD readers but with multiple card slots. Can anyone help? Alternatively, I could wait for a 64GB iPod Touch if they ever make one
