  1. Today Mushkin announced their latest SandForce SF-2281-powered SSD called the Chronos and Chronos Deluxe. Aimed at both the enthusiast and value-oriented enthusiast markets, Mushkin differentiates each model with the type of NAND flash included. The higher performance Chronos Deluxe model will use faster synchronous NAND, while the budget-friendly Chronos will use asynchronous NAND. At its peak, the Chronos Deluxe boasts speeds upwards of 560MB/s read and 530MB/s write. Read Full Article
  2. I have to admit that a little over a year ago, the only redundancy I have with important family files was by folders copied and pasted to different drives in the same system, and the yearly "merging" of my digital camera folder with my parents. Basically if one drive took a turn for the worse, something else would be there but maybe not up-to-date. About a year ago I turned back to using a server, had RAID1 over two volumes (1TB and 2TB) and had some parity in my home, but didnt really work on the family setup. Well that is until about a month ago. After getting very intimate with the Synology NAS units, convincing my father to get one, and having one at home and work, I have setup a near disaster-proof backup/mirroring plan. Right now this is the setup we are rolling with, with some *secure* backups coming in place shortly. My Home NAS > 4 x 2TB RAID5 Parents NAS > 2 x 2TB RAID1 Work NAS > 4 x 1TB RAID5 Each of these units are accessible through the net using DynDNS, all are kept updated so software is matched across each model. Each NAS has one volume, with different stuff in various folders. Main ones are listed below: Digital Camera Pictures (obvious) ~120GB Work Stuff (StorageReview pre/post-review images, draft documents, test data, everything vitally important) ~10GB Home Stuff ( Firefox backups, tax documents, backup of licenses, etc) - 2GB Family Stuff (Budgets, father's work stuff, Outlook backups, misc crap) - 1GB Right now we have scheduled backups of each of the folders except my home stuff for now. Using incremental block-level backups, since a lot of the data stays the same each time, just with changes or additions. Backups are set weekly on some stuff, with large items set monthly or manual. Plan going forward will be a bi-yearly copy of all those folders to a notebook drive that will get placed in a safety deposit box. While not tape backups, I think we are doing pretty good. Data is mirrored across multiple states, four different locations, nothing in flood zones, and all NASes are on battery backups. Now media is mirrored between systems and servers locally, but not across multiple servers. It just falls into the category of not being worth it considering its size, ease of reacquiring, and multiple forms of local backups (the ipod counts!). So what are you guys doing?
  3. Figured I would make a sticky about this, since we have had a number of drives in-house that were exhibiting excessive head parking. This includes the 750GB Scorpio Blue (head parked every 4 seconds), Caviar Green 2TB (8 sec), and the Caviar Green 3TB (8 sec). On each of these drives support pages, Western Digital makes no mention of a utility that can correct this. Thankfully though, they do make one, and its compatible. I just spent the last 15 minutes going through about 6 drives and disabling the IDLE3 timer completely. In a NAS we are testing, the Caviar Green 2TB models were racking up 500-1000 load cycles a day. First Step http://support.wdc.com/product/download.asp?groupid=609&sid=113 Download WDIDLE3 It didn't mention the drives I was working on being compatible, but it was. Second Step Make a bootable USB Key. The guide that was super simple for me to follow was here: http://www.bay-wolf.com/usbmemstick.htm Third Step Now to actually use the program, follow the instructions on making the bootable drive, and once it is done you should have a fairly large partition to copy files onto. Grab the WDIDLE3.exe and copy it on over. Final Step Now for simplicity, I liked connecting only one drive at a time to my computer. The system should boot directly into the DOS prompt from that key you just made. Type "WDIDLE.exe /R" This will give you a readout of the drive model and serial number, as well as the current timer if the drive is supported. You can adjust the idle time, but if you are googling around enough to find this post, chances are you want nothing of it. Type "WDIDLE.exe /D" This will completely disable the timer. Verify the timer is disabled by typing "WDIDLE.exe /R", and if it still lists disabled, power off the system, or if you have other drives, disconnect the current drive and plug in another. Hope this helps you guys out. Also WD also offers a utility to adjust the spinup time on supported drives. It is linked below and follows the same steps: http://support.wdc.com/product/download.asp?groupid=609&sid=114&lang=en
  4. This past spring Seagate started shipping the 3TB Barracuda XT (review) which was a pretty solid offering. Seagate quickly followed up that release with an announcement that a new 3TB Barracuda XT would feature three 1TB platters instead of the five 600GB platters seen in the first version. Seagate's about a quarter late in delivering the new 1TB platter technology, but sometimes new technology is better late than never...especially when top line sequential read and write speeds top 190 MB/s, an improvement thanks to the new platters of 30%. Seagate Barracuda XT 3TB Review (1TB Platters - ST3000DM001)
  5. Seagate has announced their second generation solid state hybrid drive (SSHD), the Momentus XT 750GB with FAST Factor. The new Momentus XT adds 250GB of total capacity over the first-generation XT as well as double the cache NAND, going from 4GB to 8GB of SLC NAND. Seagate is perhaps most enthusiastic though about what they're calling FAST Factor technology; a series of on-board software enhancements that give the new Momentus XT an extra performance kick. These new SSHDs boast fast speeds in single drive configuration, which gets really interesting when you pair two in RAID0 as we'll show in this review. Read Full Review

    Yet another "first time RAID questions" post

    For #1, generally RAID controllers will detect SMART errors and report back. If its a bad enough error it might drop it out of the RAID or at least give you some warning. I'll cross check that though to make sure. Writing caching can never hurt, unless you have a power failure and you dont have a BBU or a UPS. Its acting as additional cache in front of the drive, so even a RAID0 of one drive would benefit. We haven't seen that topic come up yet, and there are many enterprise projects using consumer-class SSDs in RAID that work fine. Which SSDs were you planning on using? That RAID card is probably your best bet... dead reliable and able to perform at levels higher than you'd probably want to throw SSDs at.
  7. Today OCZ announced the new VeloDrive PCI-Express SSD, powered by four SandForce SF-1565 processors. The VeloDrive is aimed at enterprise users who demand very fast speeds and scalability, which this product delivers on in all counts. The VeloDrive supports both hardware and software RAID modes and can be deployed in most servers with its low-profile design. It also has minimal system resource hit and a very small DRAM footprint.

  8. Addonics Technologies has introduced its HPM-XU hardware port multiplier which can connect up to five SATA devices including hard drives to eSATA or USB 3.0. The device features hardware RAID support including RAID 5. The RAID configuration can be set using dip switches or the included software utility. Read Full Article
  9. 4TB hard drives are the next step up from the 3TB top capacity that the market has been used to for the last year or so. The problem is, 4TB drives haven't quite officially hit the market yet and there's the hard drive shortage problem, so the timing of 4TB drives coming to market is a bit uncertain to say the least. Seagate generally releases hard drive capacity bumps in their branded products first, before releasing the bare drive. That's the process they went through when the 3TB Barracuda XT came to market and that's the same thing they're doing with the 4TB Barracuda XT. We recently reviewed the 4TB Go Flex Desk and couldn't resist cracking the case open to get access to the 4TB Barracuda XT hard drive inside. Read Full Review
  10. Fusion-io has built an entire brand around speed - their ioDrive PCIe SSDs have long been touted as some of the fasted storage devices on the market. If your enterprise needs even more performance in a single PCIe slot, then there's the Fusion-io ioDrive Duo, which basically doubles down on performance. We put a 640GB Duo to work to see if lives up to the promises of speed, speed and more speed. Read Full Review
  11. Seagate's Constellation enterprise hard drives come in 6Gbps SAS and SATA interfaces; we pit them against one another using the second-gen Constellation.2 2.5" drive and fifth-gen Constellation ES.2 3.5" drive. The following models are participating in this review: Read Full Review

    OCZ Everest 2 Performance Preview Discussion

    Not necessarily, if you look at the Octane the performance kind of hit its top end early on but it stayed flat throughout the higher queues. If the Everest 2 is able to push higher speeds right off the line it would be way more beneficial to end users who would feel more impact from that versus guys who might load the drive down in a heavy multithreaded environment. That and from what we have seen so far the Everest 2 is well above the Sandforce controllers in both read and write speed as is with incompressible data. Scaling well or not at higher queues it is still pushing higher speeds.
  13. Back in July we reviewed the 120GB Force Series GT and now we finally get our hands on the larger 240GB model. With the 240GB SSD market getting extra attention these days, we put it to the test, stacking it up against other 240GB models, as well as its smaller 120GB brother. Read Full Review
  14. Looking to give away some hard drives, and this time I will add some options into the mix. Looking for a low-power 2TB drive? Maybe a high-performance 3.5" drive? Or how about you need something for a notebook? Well you are in luck! Right now I have a mix of drives that I can give away to help clear up some space in the lab. 2TB 3-platter (new version) Western Digital Caviar Green or 2TB Seagate Barracuda LP/Green 1TB Western Digital RE3 500GB Hitachi 7K500 750GB Western Digital Scorpio Blue Depending on the number of replies I get, I will be flexible on the first cut-off date. After that we will continue until the original list is gone. As times goes on I will update this thread with additional drives we can clean out of the lab.
  15. Plextor announced a new line of solid state drives, the M3S. The M3S weighs in at 2.5” with a bracket to adapt to 3.5”, comes with a 5 year warranty, and comes in a variety of capacities: 128GB, 256GB, and 512GB. The new line also boasts sequential read/write speeds of up to 525MB/s read and 445MB/s write, and random read/write speeds of up to 70,000/65,000 IOPS. Read Full Article
  16. Almost a year ago we reviewed the first hybrid SSD/HDD (well, first in a long time); the Seagate Momentus XT. Since that time it has remained the one and only drive in the hybrid drive category and gained a ton of popularity in the enthusiast market. While offering a very good mixture of performance and capacity, which can be crucial in single drive notebook configurations, there were limitations like fast spin-down times and the small cache size that many hoped would be fixed or improved. Today we look at the latest firmware patch, dubbed SD24 for the Momentus XT, which helps fixes this drive's most complained about flaw; lag associated with spinning down too quickly at idle.

    Gheto DFT?

    Outside of using something like spinrite on the drive to force hundreds of attempts, each drive uses their own unique way of handling bad sectors. Heck I still have some in the pending category on this 3TB HD that has been sitting in my NAS with over 5000 hours on it without any luck.
  18. I'll try to reclone the OS back tomorrow and get the PCMark7 stats using the mSATA alone. And yea benchmarking caching solutions does present an interesting problem since you are effectively benchmarking "hot data"... the more you run the test the more the data gets burned in. In the real world each user's experience will vary depending on use and applications.
  19. One suggestion might be watching the performance monitor while the benchmark is running. If the application is using all the bandwidth then great, but if another thing comes up and takes over for a bit that is your culprit.
  20. The easiest and safest way would be using a tool such as this: http://eshop.macsale...ology/TOOLIPOD/ That will let you slide around the perimeter, popping all of the plastic clips without marring the glossy black surface. Step one is popping off the serial number sticker, step two is sliding in one of those tools to the case half edge and sliding it all around carefully.
  21. HighPoint Technologies has announced the availability of its new RocketRAID 2720SGL, which it claims is the lowest-priced SAS 6Gb/s HBA available today. Priced at $137, it has 8 ports and a PCI-e 2.0 interface. It supports many storage configurations including RAID 0, 1, 5, 10, and 50. The ports are fully compatible with the latest 3TB hard disks.

    BSOD - Is it my SSD?

    Acronis works wonders for us.

    BSOD - Is it my SSD?

    If you clone to a hard drive, everything should carry over fine. All of those SSD related changes would be automatically adjusted for. Have you updated the firmware on this particular drive yet?

    OCZ Synapse Cache SSD Review Discussion

    It is probably a limitation set by this packaged solution. In the environments this products would go you would be looking at two drives total (SSD + HDD)
