- December 6, 2007 - According to IDC worldwide "external"
disk storage systems factory revenues in the 3rd quarter of 2007 grew 5.1%
from a year ago to $4.4 billion, down slightly from the 3 previous quarters.
Total disk storage systems capacity shipped grew 49%. The top 5 suppliers in
Q307 were:- IBM,
Hitachi. Dell had the
highest revenue growth (17.9%).
The iSCSI SAN market posted 44% revenue growth year over year, reaching $207 million in the 3rd quarter. Network Appliance continues to lead this market with 20.5% market share.
"Although the mid- and high-end pricebands performed well, the majority of networked storage growth (10% growth year on year) was driven by the low-end price bands (upto $15K)," said IDC analyst Liz Conner. ...IDC profile, Market research

Editor:- December 6, 2007 - STORAGEsearch.com today revealed that the Product Category of the Year in 2007 - ranked according to reader pageviews for the 2nd year in a row was Disk to Disk Backup. Let's be frank. Nobody likes doing backup. The time, money and resources consumed by backup are considerable. It's only the fear of what can happen when disaster strikes and the consequential cost of losing critical information - that keeps the industry going.
Of all the backup media available - (hard disk, tape and optical) D2d which many vendors genteelly refer to (by the less-aggressive sounding but equally lethal-to-tape moniker) as "VTL" has evolved during the past decade from a niche activity into the most popular way of routinely replicating critical data and applications. With the current mess of hyped incompatible technologies being offered by the optical industry - the position of hard disk based backup as a convenient, economic method of corporate backup is likely to remain safe for at least the next 5 years till 2012.
After that? - the reliability and speed of hard disk backup compared to solid state alternatives may start to be questioned in the same way as the early tape versus disk debates back in 2001. But I don't expect to see widespread adoption of solid state backup to start before around 2014.

SANTA ANA, Calif - December 4, 2007 - STEC, Inc. today announced it is sampling its MACH8-MLC PATA / SATA flash SSD optimized for the notebook and portable media player markets. The new models offer high capacity - upto 128GB for 1.8" (7mm high), and upto 512GB fpr 2.5" (15mm high). Sustained sequential throughput is 90MB/s (reads) and 60MB/s (writes). Pricing has historically precluded SSDs from wide adoption in notebooks. STEC says its new MLC based implementation contributes to competitive pricing and offers this SSD family at $5/GB today, declining to less than $2/GB within 2 years. ...STEC profile, 2.5" Solid State Disks
Editor's comments:- MLC (multi level cell) flash memory stores 2 (or more) bits of data in a single cell. Intrinsically it has a higher error rate than SLC (single level cell). Because of its low cost it has traditionally been used in applications such as MP3 players or phones - where dropping the odd bit is not noticeable. However when used with stronger error detection and correction logic - and bigger data blocks - there is no reason why overall data error rates can't equal that of traditional SLC SSDs.
The historic concerns about error rates have (until now) been a factor in MLC flash not being deployed in SSDs for computer applications. However, if you look at the internal technology in a hard disk drive - media error rates are much more flaky than in flash memory. It's only the magic of the controller technology that makes hard disks useable. For the same reason it's likely that MLC SSDs will start to creep into consumer products.
A more serious concern is that MLC flash has typically 10x worse endurance than SLC. But using bigger capacity SSDs mitigates the problem. Typically a 320GB MLC SSD will have the same operating life (limited by wear-out) as a 32GB SLC SSD.
In the long term I expect the MLC vs SLC debate will resolve itself - but for now it's an issue for integrators designing high reliability servers. I remember similar past controversies when oems said that 8" hard drives were more reliable than 5.25" drives, and when new SATA hard drives were said to be less reliable than traditional parallel SCSI drives. Whoever uses a technology in a new way always takes some flak. But the rewards may be worth it.

Wallingford PA - December 2, 2007 - EasyCo LLC (a North American distributor for Mtron Flash SSDs) has just completed detailed performance testing on Mtron drives, both as single drives and in RAID-5 arrays. These tests provide concrete performance numbers for using Mtron drive in performance critical applications such as database and transaction servers, as well as in more widely used products such as laptops.
Of special interest will be confirmation that Flash SSDs operate differently in RAID-5 arrays. Hard drives running RAID-5 normally perform significantly slower than those configured RAID-10. With Flash, RAID-5 and RAID-10 perform virtually identically.
At large block sizes, the Mtron drive is 10-40% faster than a 15K RPM hard drive, mostly depending on what part of the HDD you are accessing. When coupled with the MFT management layer, the Mtron drives are basically 50x faster than a 15K HDD regardless of the read/write mix. ...read the article (pdf), ...EasyCo profile, ...Mtron profile
