Western Digital unveil the Thunderbolt-powered My Book VelociRaptor Duo

Western Digital are ready to shake up the external storage industry with their latest Thunderbolt-powered storage product, the My Book VelociRaptor Duo. The My Book VelociRaptor Duo comes with two 1TB 10,000RPM drives in RAID.

This means that the VelociRaptor Duo is capable of an astounding 760MB/sec write and 800MB/sec read. One of the better features that the new My Book VelociRaptor Duo sports is that it's user-serviceable. If you want to replace a drive, simply open the case, pull the existing drive out, and replace it with a new one.

 

The VelociRaptor Duo is also capable of daisy chaining with Thunderbolt, as the Thunderbolt technology has much more room to move within its architecture. USB 3.0 limits at around 350MB/sec of real-world performance, but Thunderbolt scales right up to 1GB/sec, meaning that you'd need to have some seriously fast internal storage to get close to that 1GB/sec mark.

 

MSRP on the 2TB WD My Book VelociRaptor Duo is $899.

FMS 2012 - LSI and SandForce featured everywhere, a summary

Flash Memory Summit 2012 - It really didn't matter where you were standing at Flash Memory Summit, within ten feet was a product with either LSI or LSI SandForce silicon.

 

For years, LSI has played a significant role in several markets, video processing, encoding and so forth, but their largest presence has been enterprise storage. SandForce, before joining LSI was known for their consumer SF-1200 and SF-2200 controllers, but these products were created from their enterprise counterparts, SF-1500 and SF-2500. The enterprise SandForce parts were successful on their own, but by adding three letters to the SandForce name, LSI SandForce flash processor units are now displacing the competition from the enterprise sector.

These are not DDR3 DIMMs, they are Viking SATADIMMs using LSI SandForce SF-2500 Series FPUs. These products draw power from the DRAM bus, but are enterprise SSDs in an innovative form factor that allows for unprecedented scalability...

FMS 2012 - Biwin Preparing Multi-Drive SF-2281 RAID on PCIe

Flash Memory Summit 2012 - At Computex, Biwin distinguished themselves from the herd by showing the first Novachip Bugatti controlled SSD, NuvoDrive NX. We spent a few days with the upcoming NuvoDrive NX but that is old news now because Biwin just displayed an even more exciting product at Flash Memory Summit 2012.

 

TweakTown image news/2/5/25486_01_fms_2012_biwin_preparing_multi_drive_sf_2281_raid_on_pcie.jpg

 

We didn't get a chance to ask Biwin about the new drive but you know we are on top of it this morning. Under the heatsink is an undisclosed RAID controller, most likely either LSI or Marvell. Four mSATA SSDs using LSI SandForce FPUs are on each side for a total of eight.

 

TweakTown image news/2/5/25486_02_fms_2012_biwin_preparing_multi_drive_sf_2281_raid_on_pcie.jpg

 

On the connector side we found an 8x PCIe 2.0 connector, the industry standard at this time but PCIe 3.0 is just around the corner so this product may be shadowed by the start of 2013. Still, we'll take 8x LSI SandForce 2281 performance with PCIe 2.0 as a starting point.

 

We're excited about this one for sure!

Kingston First to Release TRIM Fixing FW for LSI SandForce Based SSDs

American Airlines Flight 1318 - High in the skies, somewhere between Dallas and Indianapolis we would like to interrupt your morning with this special announcement.

 

Just moments ago we received confirmation that Kingston has released firmware version 5.0.3, AKA The TRIM FIXING FIRMWARE, for the HyperX and HyperX 3K!!!!!!!!!

 

TweakTown image news/2/5/25483_001_kingston_first_to_release_trim_fixing_fw_for_lsi_sandforce_based_ssds.png

 

Using Kingston's Toolbox, a free SSD utility located on the Kingston's support website, HyperX and HyperX 3K owners will be the first to gain access to the new firmware that fixes TRIM in Windows.

 

Obviously since we are in the air we have yet to update our sample HyperX 3K but we have installed the FW in beta form. This is a non-destructive update but I would suggest treating this update as destructive.

Flash Memory Summit 2012: OCZ shows off a SSD that uses DRAM as the memory

OCZ's AEON Series drive is probably one of the coolest things I saw at Flash Memory Summit 2012. This drive ditches the typical NAND memory in favor of using DRAM chips which have no durability issues. These chips are clocked at around 40MHz as opposed to a typical DDR3 stick which could be clocked as high as 800MHz.

 

TweakTown image news/2/5/25447_4_flash_memory_summit_2012_ocz_shows_off_a_ssd_that_uses_dram_as_the_memory.jpg

 

Essentially this drive is like your DDR RAM in your PC. It's faster than a typical SSD due to the use of volatile memory, however, if the power goes out, the data is lost. It's almost like a RAM disk, though the bandwidth is limited by the interface. In the event of a power loss, the data is flushed to typical NAND memory.

 

The drive's capacity is up to 64GB as of right now, and has super low latency (20 microseconds or less) and typically is about 1 microsecond. The chip is built to be used in servers and features a 6GB/s SAS connection. Note that these are preliminary specifications which are subject to change. Even still, this is a sweet drive!

Flash Memory Summit 2012: Toshiba demos new HybridDrive, races it against an SSD

I've never really been a believer in hybrid hard drives as they've never been competitive to SSDs when it comes to speed. Today at the Flash Memory Summit 2012, Toshiba had a demo showing just how wrong I could be. They had three identical laptops set up, one with a 19nm NAND SSD, one with a 5,400RPM drive, and one with an undisclosed hybrid drive.

The demo was booting from a completely powered down state into Windows and then starting a movie playing. Some of the results were shocking, to say the least. The traditional 5,400 RPM hard disk of course came in last as you would expect. However, the hybrid drive and the SSD were locked in a dead heat to the finish.

 

While the SSD finished before the hybrid drive, it couldn't have taken the hybrid drive more than 2 seconds longer. This result is quite a bit different from what I have seen in the past with regards to hybrid drives. When pressed, Toshiba wouldn't say when we would see this hybrid drive on the market or really give us any info. The best I could get from them is that it is a demo showing what is possible. All of a sudden hybrid drives are looking a whole lot more attractive.

Toshiba increases enterprise SSD offerings with three new lines

Here's a mouthful for a business name: The Storage Products Business Unit of Toshiba America Electronic Components, Inc. Anyway, these folks have announced an expansion to their enterprise SSD offerings in the form of three new lines of varying capacity and specifications. They bill the three lines as "High Performance," "Value," and "Read-Intensive/Boot Server."

 

TweakTown image news/2/5/25407_1_toshiba_increases_enterprise_ssd_offerings_with_three_new_lines.png

 

  • High-Performance: Targeted at applications requiring the highest levels of eSSD performance, the PX02SM series is Toshiba's first eSSD to utilize 24nm eMLC (enterprise multi-level cell) NAND technology, with capacities of 200/400/800GB1 and 1.6TB2, and is Toshiba's first offering with a dual-port 12Gb/sec SAS interface with a form-factor equivalent to industry-standard 2.5inch HDDs.
  • Value Line: Optimized for entry-to-mid-level server and storage applications requiring balance, reliability, capacity and endurance, the PX02AM series also features 24nm eMLC NAND flash in capacities of 100, 200 and 400GB, all with a 6Gb/s SATA (Serial ATA) interface. Featuring a slim 7mm 2.5inch industry-standard form-factor, all capacities offer power-loss protection.

Marvell unveil Flash-based innovations at Flash Memory Summit

Marvell have unveiled some things over at the Flash Memory Summit (where some of our guys are schmoozing with the crowd), with the first of these being the general availability of their PCIe-based DragonFly platform. If you haven't heard of DragonFly, it's a platform that combines Marvell's SoC technology with newly-designed circuit boards, and uses PCIe as its connectivity.

 

TweakTown image news/2/5/25404_07_marvell_unveil_flash_based_innovations_at_flash_memory_summit.jpg

 

The results of this are storage solutions that can provide 10-100x lower latency and improved server I/O performance, all while using less power, space and storage capital costs in a datacenter. Marvell's DragonFly platform will be commercially available from September 15, 2012. Marvell's specs on DragonFly are pretty insane, as they've shown:

 

DragonFly is sold as a PCIe Gen2 x8 adapter with up to 8GB SODIMM ECC DRAM and up to 1.5 TB of external SSD storage; read, write-back and write-thru caching; synchronous low-latency peer-to-peer write-back mirroring; 3.2GB/s of throughput; less than 22us latency; 220K IOPS read; 220K IOPS write; integrated ultracapacitors to protect data in the event of power loss; and a wide variety of host operating system support, including RHEL, KVM, Xen, VMWare and Windows.

DNA-based storage contains 700TB into 1 gram of DNA, could we soon see DNAS' on the market?

I hope you enjoyed the pun in the title, but seriously, I want a DNAS as soon as possible. Grab your lab coat, because we're about to do a quick science post. Harvard geneticist and bioengineers George Church and Sriram Kosuri with the help of John Hopkins Yuan Gao have stored 5.5 petabits (700TB) of data into one gram of DNA.

 

TweakTown image news/2/5/25398_07_dna_based_storage_contains_700tb_into_1_gram_of_dna_could_we_soon_see_dnas_on_the_market.jpg

 

The accomplishment of these scientists, is grand, as it beats the previous DNA data storage record by more than 1000 times. DNA-based storage is attractive to scientists, as DNA itself is quite dense, requires absolutely no moving parts when stored, and is durable. Usually data is stored on magnetic media, versus DNA strands storing 96 bits, with each of the base pairs representing a binary number.

 

In this case, Adenosine and Thymine represent zero, and the Guanine and Cytosine represent one. Each strand of DNA is encoded with a 19-bit address block allowing vast quantities of DNA to be stored volumetrically to be decoded and sorted so that usable data can be extracted, 96 bits at a time. In comparison, the original human genome project, with 3 billion base pairs, took 13 years to complete (from 1990 to 2003).

OWC unveils SSD upgrade for Retina MacBook Pro

OWC have just announced the first SSD upgrade for the Retina-powered Apple MacBook Pro, with the new drive available on a single 480GB capacity. The upgraders who purchase before September 30 will receive OWC's Envoy Pro USB 3.0 bus-powered portable enclosure that will house the removed SSD, and use it as an external drive at no extra cost.

 

TweakTown image news/2/5/25303_06_owc_unveils_ssd_upgrade_for_retina_macbook_pro.jpg

 

OWC's drive is dubbed the Mercury Aura drive, and is user-installable. The Mercury Aura drive is capable of 500MB/sec, compared to the stock Apple drive of 461MB/sec. The Mercury-branded SSD is also capable of block management and wear leveling technologies, which limits the reduction in speed common in SSD drives over long-term use.

 

The Mercury Aura 480GB sell for $580 and is available right now.
