Western Digital Blue WD3200AAKS 320GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5' Internal Hard Drive Bare Drive Ships from United States. Most customers receive within 9-18 days.
3 00MB PER SECOND Serial ATA transfer rates are all the rage these days. Cutting-edge core logic like Intel's ICH7 south bridge chips and NVIDIA's nForce4 family support the faster I/O interface, and hard drives are beginning to follow suitnot that a faster interface is really needed.

Even 15K-RPM SCSI drives struggle to sustain transfer rates that would saturate a 150MB/s Serial ATA pipe. Western Digital's Caviar SE16 is the latest hard drive to jump on the 300MB/s bandwagon, and fortunately, this Caviar is sporting more than just support for a faster Serial ATA interface. The drive also features a beefy 16MB cache and a stealthy all-black aesthetic that's unlike any other hard drive on the market.
Curiously, though, Western Digital has elected not to support Native Command Queuing (NCQ) on its latest high-performance desktop drive. Will that decision hurt the new Caviar's chances against the latest NCQ-equipped Serial ATA drives from Hitachi, Maxtor, and Seagate? Let's find out. Caviar SE16 Caviar SE Maximum external transfer rate 300MB/s Internal transfer rate 93.5MB/s Average read seek time 8.9ms Average rotational latency 4.20ms Spindle speed 7,200RPM Cache size 16 MB 8MB Platter size 83GB Available capacities 250GB 80, 120, 160, 250GB Idle acoustics 28dBA 26dBA Seek acoustics 33dBA 31dBA Idle power consumption 8.75 W Seek power consumption 9.5 W Native Command Queuing? No Warranty length One year (Retail) Three years (OEM) Most notably, the Caviar SE16 has 16MB of on-board cache, double that of the rest of the Caviar SE line. The SE16 is also only available in 250GB capacities, which saves cheapskates like me from choosing a drive capacity based on the most favorable cost/gigabyte ratio.
Apart from cache size and capacity, the Caviar SE16's vitals are virtually identical to those of Western Digital's 300MB/s Caviar SEs. Make sure you get the right drive, though, as the model numbers can be confusing. The Caviar SE16's model number is the WD2500KS, while the Caviar SE is tagged as the WD2500JS. What a difference a letter makes. It's really no surprise that the Caviar SE and SE16 share similar model numbers considering the fact that they both spin 80GB platters at 7,200RPM. The relatively low-density platters are a bit of a surprise, especially considering that Western Digital's competitors have pushed areal densities up to 133GB per platter.
Higher areal densities can translate to faster performance by allowing drive heads to access a greater amount of data over shorter physical distances. According to Western Digital, the SE16 is simply an 80GB platter drive with a new logic board. In addition to snubbing higher density platters, the Caviar SE16 also lacks support for Native Command Queuing (NCQ). Command queuing can improve drive efficiency and potentially performance by intelligently reordering I/O requests to reduce rotational latency, but Western Digital claims that adding NCQ to the SE16 would hurt sequential read and write performance. The fact that Intel's vanilla ICH7 south bridge doesn't support NCQ is also cited as a justification for the SE16's lack of command queuing support, although it's odd that Western Digital would use a mainstream south bridge spec to determine features for its 'highest performance' desktop drive.

Moving to warranties, the Caviar SE16 is covered by a three-year pact, but only when bought as a bare drive. Retail drive kits, which are usually more expensive, are inexplicably only covered by a one-year warranty.
Normally, I'd preface our snapshots of the Caviar SE16 with a snooty comment about how it looks like every other hard drive, but surprisingly, it doesn't. The Caviar SE16's look isn't wildly different, but a little goes a long way in a sea of look-alike hard drives.

WD Community Sorry, but our agent didn't know that this policy was just changed. Current WDIDLE3 works with the RE and GP drives listed below. RE Drives - WD1000FYPS-01ZKB0, WD7500AYPS-01ZKB0, WD7501AYPS-01ZKB0. Hi, DLG should also be compatible with the wd red.
Managed to get a reply from Support. It appears that there were several batches of drives that were sold that had firmware improperly configured. This firmware problem seems to be very specific to.
