| 57 of 58 people found the following review helpful  And, there was much happiness..., By Amazon Verified Purchase(What's this?) This review is from: WD RE4 2 TB Enterprise Hard Drive: 3.5 Inch, 7200 RPM, SATA II, 64 MB Cache - WD2003FYYS (Personal Computers) I'm not normally a fan of SATA drives, I've worked extensively with SAS/SCSI drives for servers/etc for the last 20 years and only used ATA/SATA when required.Still, I've had some projects come up recently where the only option was SATA and high capacity was required. After some bad experiences with the WDC Cavier Black 2TB, I gave the RE4 a try. It's been great. I've now had 5 of them running for the last six months and the SMART monitoring reports still show the drives as in almost new condition...no errors, no need for sector changes, no unusual increases of load cycle counts, etc. Performance has also been very good....surprisingly good for a mere 7200rpm device. Not to mention, the drives seem to work nicely in both software and hardware raid. I'll probably end up buying another 5 of them soon. I'll be very happy if I can keep the failure rate to under 4%/yr....this historically is a good rate for SATA/ATA. I'm not sure what to think about WDC.....I generally prefer seagate, but the RE4 drives certainly seems to be able to back up its claim as an enterprise SATA drive. 56 of 61 people found the following review helpful Big Daddy with huge cache, By Amazon Verified Purchase(What's this?) I was skeptical at first.But I bought two, and put in a RAID1 mirror config, in a 8-drive raid box with 2 x multilane infiniband interfaces and a RocketRaid card. The 64MB cache is noticeable, totally. It is not hype. On average, I get 100MB/sec copying across a gigabit network in the LAN from one machine to this RAID volume. In a similar test (using the same source machine, to a volume of 750GB AAKS', I get ~82MB/sec across the wire. Again, the cache is noticeable in my tests. I am amazed at the quality of this drive. I recommend these drives to anyone who needs to use a RAID config, and needs capacity, and reliability. I only use WD, period. I currently own 46 hard drives, all WD. The only WD hard drive I ever had fail, was a green 750GB one. The older AAKS series was phenomenal, and these are the new ones to get! (I have had drives fail a great deal using other manufactur ers) appdevman 21 of 21 people found the following review helpful Solid Performer at a Fair Price, By Amazon Verified Purchase(What's this?) This review is from: WD RE4 500 GB Enterprise Hard Drive: 3.5 Inch, 7200 RPM, SATA II, 64 MB Cache - WD5003ABYX (Personal Computers) I bought this to replace a Seagate backup drive that lacked enough room for drive images. The WD5003 is quiet and speedy and comes with a 5-year Enterprise warranty. No problems with it at all.Buyers have been complaining about Amazon's poor bare-drive packaging in many of the reviews I've read. However, this drive was packaged properly in a box of its own made by WD, with plastic end caps suspending the drive over the bottom of the box. This package was put in another box with the rest of the items I ordered and a couple of air pillows. Perhaps Amazon has listened to the well-founded complaints and revised their bare-drive shipping accordingly. Then again, it might only apply to this particular hard drive. |

| 191 of 196 people found the following review helpful Fast, efficient, quality product..., Amazon Verified Purchase(What's this?) This review is from: Fujitsu ScanSnap S1500 Deluxe Bundle Sheet-Fed Scanner (Office Product) I have scanned about 8000 sheets so far. I have found these settings helpful with rack2filer:1. Auto color detection, Duplex, Best image quality (300dpi Color/Grey 600dpi BW), Options [Only Blank page removal checked (no auto rotation - slows down page viewing)], Continuous scanning. 2. Same as above except change color mode to gray. And in general I have found: The multifeed detector works great and has detected many double feeds. It handles old thin thermal fax paper without double feeds - pretty amazing, because I would think that if anything would jam or double feed it would be that. The prompt shows the image of the detected multifeed and gives you the option of keeping it or discarding it - this has been helpful when it detects sticky notes on scanned paper that are supposed to be there. It has handled many old papers - barely legible and has done an adequate job picking up light print. Very light or old papers with light print or pencil hand writing are better handled by forcing the color detection to grey. Otherwise Auto everything works well. Blank page detection - does not work with the other side of lined loose leaf paper or graph paper that has nothing written on it. That is to be expected - but a possible design improvement idea for this product. And to get around this, I have set the scanning side to single-sided. Otherwise blank page detection worked well. Scans looked exactly like the originals and in rack2 filer the binders read and looked as well as the paper binders. When it does jam (which was rarely the scanners fault and mostly from staples, taped paper or over loading), the prompt shows the last few pages scanned which makes it easy to recover. Fanning and creating a step-like pattern of your paper stack before loading the paper makes a big difference in preventing paper jams. Some of the advanta ges: I can take many binders worth on information with me on my notebook without dragging the heavy paper binders in my bag - or one of those wheeled bags that my colleagues use. There is the security of now being able to have multiple copies of my binders in physically different locations [desktop, notebook, and off site backups] all without using a copy machine. I need less space for file cabinets [files], bookshelves [binders], and thus less office space. Everything is now in one place. My office is too small to have all my binders and files together, but now they all fit in one folder on my hard drive. Although I will still use paper to write on, I don't foresee a reason to ever need to bind or file papers anymore. Just take notes, scan, and recycle. The actual images for Rack2Filer and CardMinder are in PDF files so if anything happens with Rack2filer - you can always access the data via windows explore r and acrobat. I have used NeatWorks for my accounting (receipts), documents, and business cards for about a year now. The mobile scanner scans at 3 ppm black and white and 2ppm color - single sided only. So for duplex color ScanSnap is (20ppm x 2)/2ppm = 20x faster - a huge improvement. The NeatWorks software is also heavy and slow compared to Rack2filer and CardMinder. However, NeatWorks is better than ScanSnap organizer or Rack2filer for receipts. And it can import the PDF scans from the S1500. So, I recommend using NeatWorks software (not the NeatWorks/Desk scanner) for receipts, Rack2Filer for documents and CardMinder for Business cards. 623 of 654 people found the following review helpful  Good hardware but no twain driver is a significant limitation, By Amazon Verified Purchase(What's this?) This review is from: Fujitsu ScanSnap S1500 Deluxe Bundle Sheet-Fed Scanner (Office Product) I purchased this scanner as a first step in creating an electronic filing system for a home office. As I accumulated 20 filing cabinet drawers of paper documents going paperless seemed to be an answer.Purchase of the Fujitsu S1500 was based on the numerous 5 star reviews. I am reasonably tech literate and have used the scanner for about 2 weeks. Here are my initial impressions: Pros - 1. Speed: This scanner seems blazingly fast. Not a resource hog. Will scan duplex 20-25ppm at default settings on Win2K/1.8mhz/1gb platform. 2. Scan quality very good at all settings. 3. Size and looks: Small desk footprint. Looks great open or closed. 4. Excellent paper feeding as long as documents are same size and 20# or greater paper weight. Cons - 1. NO TWAIN DRIVER. I knew this going in but did not appreciate how much this would cripple the device in day to day use. Let me explain. I had envisioned cre ating a virtual file cabinet in my computer using Windows Directory/Folder/File system then scanning my paper documents into this system as pdf files. The problem is that the native Fujitsu software does not let you append an existing pdf file!!! As an example take a file for utility bills. D:/Home Expenses/Utilities/Gas_Electric.pdf. You can easily scan in all prior bills(limited by 50 sheet ADF)and a pdf with one page for each bill will be created. But if you had more than 50 prior bills or when next months bill comes then the next scan you perform to include these new documents will create a new pdf and does not allow the option of appending this more recent scan to the existing pdf. As you can see one could easily end up with 1000s of individual pdf documents in your filing system. The work around is to launch Adobe Acrobat (not reader) and use it to open the old composite pdf and use Acrobat to append the newly created pdf to the prior file. This work around takes longer than scanning in a 30 page document. Twain based scanners easily work with existing windows file structure and allow you to append an existing pdf without invoking Acrobat. 2. Paper catch tray very fragile and ADF paper support does not stay up (also reported by other reviewers). 3. Double feed sensor: stops scan and reports. This is good. However you cannot retrieve the double fed sheet and place it back in proper order because the next sheet is already in the scanner and cannot be backed out. You have to either cancel the scan and start over or put the unread sheet back in out of order and then use Acrobat to rearrange the pages in the resultant pdf document. If you choose to cancel the scan the document that is halfway into the scanner will not be ejected and you need to perform an new scan to retrieve that sheet. 4. A scanning run will only handle one size document at a time. In my experience if you have a mix of paper sizes you will need to do a scanning run for each paper size. Each run will generate a separate pdf file with you will then need to deal with. 5. I paid extra for the scanner bundle with Rack2File software thinking it would help me create the filing system I envisioned. After loading and spending several hours with this software I don't understand how it works or what it is supposed to do. I consider the extra dollars I spent for the "bundled" scanner money poorly spent. 6. Other minor annoyances are: While the scanner and snapscan software will run on older platforms the bundled software Rack2file and Acrobat require XPpro SP3 or newer. This is not clear from specs. ADF will hold 40-50 sheets but output tray will start to jam after 20-25 sheets. Documents printed on less than 20# paper and with printing on both sides the back side printing will show up on the front side scan. Many commercial invoices are printed both sides o n thin paper. Cannot set several default scanning profiles. You need to reset the scanner parameters each time you want a different profile. Bottom line: This would be a 5 star low end document scanner if it only offered a twain driver. As it is I can recommend it only to prospective buyers who understand the full implications of this limitation. I thought of returning this scanner and getting one of the twain based models like the Epson GT S50 but at this point I have learned enough of Acrobat to quickly append my pdfs retrospectively. I strongly recommend avoiding the "bundled" product since I don't see what added value the Rack2File software brings. I considered giving the scanner a one star review just to get people's attention but the hardware is so good 3 stars seems about right. 146 of 153 people found the following review helpful This little scanner is awesome!, This review is from: Fujitsu ScanSnap S1500 Deluxe Bundle Sheet-Fed Scanner (Office Product) My old HP scanner (actually, it wasn't that old) died a few months ago and it was time for me to get a new one. I accidently came across the predecessor to the ScanScap S1500 (the S510) last week while I was having my taxes done and was amazed at the speed and compactness of it. My tax person also gave it glowing reviews. As I wasn't aware that Fujitsu manufactured scanners, I thought I'd do a little research which led me to reviews of the S510 here on Amazon. Rather amazingly, I was very surprised to find that the S510 had so many extraordinarily high reviews (something that I don't believe I come across too often, especially with items such as scanners). One of those reviews mentioned that a new model (this one - the S1500) had just been released by Fujitsu. After some more research (it wasn't yet listed on Amazon), I found that this scanner was available and that it had many new features. As it turns out, I was the "first kid on my block" to acquire one and I'm glad I did! This machine is incredible!The speed is absolutely blinding - an incredible 20 pages per minute but, because it scans both sides of a page at the same time, double sided documents scan at 40 PAGES PER MINUTE! Wow! As with previous models, this scanner is very small and appears to be well built: it's quite heavy for its small size and fits very nicely on my small computer desk. The scanning quality is equally spectacular - it scans up to 600 dpi in color, grayscale, and black and white and mine came with a good assortment of software (Adobe Acrobat 9, Rack2-Filer, and ABBYY FineReader). It scans documents beautifully! While I've been too busy scanning the billions of pieces of paper that have cluttered my life for years (this scanner will actually do that quickly and efficiently - something I've always just dreamed would be possible), I haven't yet tried to scan photos; I suspect that this scanner will do a good job but that another type of scanner would probably do better for archival purposes). The only problems I've had were with Acrobat (I already have Acrobat 9 Pro on my computer) - I found that importing previously scanned documents into Rack2-filer were always listed in reverse order (ugh!) and Fujitsu tech support replicated the problem. They suggested, however, that I completely uninstall (not just repair) Acrobat and reinstall it. That did the job. BTW, I received great tech support from Fujitsu. One interesting thing is that this scanner does not come with TWAIN drivers. Because of this, it is not possible to use it to the same extent as other scanners. Just the same, my reason for getting this scanner was to create .pdf files and this scanner does it like no other. Overall, I'm thrilled with the Fujitsu S1500 - there is no question that it is the best one I've had (and I've had many) and is well worth the money (the S1500 is also the most expensive scanner I've ever purchased). I would re commend this to anyone who needs to scan documents. |
