More valuable, however, is the fact that the review offers a detailed comparison of 17 different Serial ATA drives from Hitachi, Maxtor, Samsung, Seagate, and Western Digital. Performance is compared across a wide range of typical desktop, multitasking, and multi-user loads, and noise levels and power consumption tests also provide interesting results. Definitely worth a look for anyone in the market for a new hard drive."

Re:Loud noises! (Score:5, Interesting)
The measurements were made one inch away from the drives, so you could expect the levels to be pretty high. Unfortunately, their measurement methodology also means that the noise levels are useless for anything but comparison purposes.
It would be nice to know whether the levels were A-weighted or linear. Also, with the meter they were using, differences of less than 2 dB aren't meaningful.

The SATA standard is entirely suitable for enterprise use and has a growing collection of enterprise class drives.
Reliability is a "big issue" for almost everyone. Reliability is more important than raw performance for most of the desktop market, indeed most of the hard drive market. If SATA drives were inherently unreliable, they would be unsuitable for any market.
The only reason reliability isn't the main benchmark for a drive is that it's so hard to measure or predict. If measuring reliability were as easy as measuring noise levels, it would be the most important buying criteria bar none. Particularly since other measurable criteria do not vary all that much between modern drives at a given price point and capacity level.

Is SCSI RAID faster than SATA RAID ? (Score:3, Interesting)
My Hypotheses is simple:
1. What really matters for a RAID implementation is Reliability, Size, cost and Speed. In that order.
2. SATA drives come close to SCSI drives in individual performance. Greater data densities help and lower spin

I suppose that depends on how often your "important data" gets written. I can think of lots of applications where flash degradation shouldn't be a problem. (And yes, I can think of lots where it sure would be.) I wouldn't put /var on a flash, but maybe /usr or root. Actually, I would love to have a small flash drive to boot from, so I could completely devote my disks to LVM.

SMART support? Pretty please? (Score:4, Interesting)
The Tech Report has an in-depth look at Maxtor's DiamondMax 11 hard drive that provides some interesting insight on how Seagate's recent acquisition can improve deficiencies in its own drives.
Like better SMART support on Seagate's side? I was stunned at how much more SMART capabilities Maxtor drives have compared to Seagates and others. It should almost be a crime to produce a drive that doesn't have a SMART compatible error log (which Maxtors have- you can query it and see when+what the last errors were, for starters.)
I've also been stunned at how BAD modern drives are; a client lost FOUR maxtor drives out of a 12 drive array in the space of 2-3 months, and we literally couldn't replace them fast enough (also, the idiots that he bought the system from TURNED OFF autoverify on the 3ware controller, didn't install the linux drivers, didn't bother updating the card's firmware, etc. That'd be PCs4everyone in Boston, FYI.) I had a Seagate PATA drive with barely a dozen hours on it that started clonking like crazy if you wrote data at high speed to it for too long (no, this was not the 7200.8, which had similar issues, relating to a motor driver circuit overheating. This was a 7200.9!) Seriously- the drive would completely stop writing data if you wrote to it continuously for about 40-50GB. The only thing that let me successfully complete the imaging was a borrowed fan directly cooling the drive.
I'm not too optimistic that Maxtor and Seagate will benefit each other in terms of technology the end user will care about; what is more likely is that Seagate will go enterprise, and Maxtor will go consumer, since that is what each brand is best known for.

I had a similar situation but I really think it was because the drives were not rated to operate in an oven - which is what a badly designed case with 16 drives ended up as. That said it appears I've lost two Seagate SATA drives from a newer machine in the last two days, both halves of a mirror. I'm happy I fed it a new drive yesterday or I'd be looking at a long restore

Mechanically speaking, the SATA connector doesn't seem particularly robust. I've had problems at work with one system in which the drive would occasionally disconnect and reconnect.

I believe this has to do with the much weightier (relative to single-purpose devices) laser head arrangement that has the different types of lasers for each standard.
It also has to do with what you use the drive for. Eg: a drive that only ever reads or writes whole discs will last a lot longer than one constantly being used for random accesses.
