If your machine is an older computer with an IDE or parallel
ATA drive interface, the speed benefit you'd realize from investing in an SSD isn't big enough to justify the expense.
ATA drive products lagged for several years since such calculations were not necessary designed for the desktop market.
An
ATA drive's internal data transfer speed tops out at about 60MB/s--the maximum rate that the data head can sustain reads or writes to the disk media.
"You just need to power on additional nodes, and you get additional performance and capacity automatically."<p>Each node has 12TB of capacity and is made up of a 2U (3.5-in) x86 server with 12 Serial
ATA drives.<p>DX Object Storage has the capability of being configured as write-once, read many (WORM) storage for regulatory compliance purposes.
Serial
ATA drives come close to Fibre Channel speeds with a much lower price point, making SAS ideal for high-end applications with large capacity needs.
"This option was designed to help ease the transition from IDE to Serial
ATA drives," continued Mr.
They are designed to support up to 1.6 TB of storage capacity using high-speed serial
ATA drives and Intel's latest 3.2 MHz P4 processor with built-in 800 MHz front side bus and 1 MB cache, and fast 1 GB DDR SDRAM memory.
A combination of Fibre Channel and
ATA drives can be used in the same system for high-capacity, low-performance requirements.
The most important of these are iSCSI/IP SANs and serial
ATA drives.
Pogo Linux chose Serial
ATA drives because the emerging technology is more reliable than ATA and offers improvements in performance growth for the future.
The E400 also uses SCSI disk drives, but the larger EchoView variants will use
ATA drives, StorageTek said.
FastTrak SX4000 supports RAID 0, 1, 0+1, 5 and JBOD using up to four standard Ultra
ATA drives. The onboard Promise BIOS offers 48-bit Large LBA support to automatically recognize and optimize the performance of larger Ultra
ATA drives while supporting individual drive sizes exceeding 137GB for maximum capacity arrays.
