Compared to its larger sibling, the 1.5TB WD drive's transfer rate decays much less at the end and access times are lower. It looks to be short stroked, but not at quite the same density as the 2TB model. What gives?
Have you ever not received the foam packaging with 5 drives? I am thinking about buying the 1.5TB (WD15EADS) drives. They seem to be the best choice for massive backups at the moment.
It is practically hopeless today. :( This is the first day I've had functioning internet for a while, yet it has been lousy for a few weeks. I think Doug is working on another IP.
David just wants to do things the "new" way, never mind IQ loss from sensor blooming, registration degradation, etc. :) In the old days we had concepts like metering for the subject and the zone system.
Just get one X25-E on a SATA 2 or SAS 64-bit PCI-X controller. I would not spend too much on one, given the obsolescence of your system. SATA 1 is noticeably slower, but faster than your old SCSI drives of course.
Realistically a transfer rate of about 270 MB/sec. can be achieved per drive from buffer to host. SATA 3.0 will be about double that. SATA RAID is limited by the processor and PCIe implementation which is usually 8x for the second slot. Some boards may have more lanes. How much do you want...
Copy speed slows down with small files, but that happens with all drives. It is about half full and the speed is still very good, similar to the Seagate. I'm sure that perfomance will suffer when the drive is more full and when fragmentation sets in. I always use 32K clusters. The drive sure...
The drive is fine. Transfer rates are good, starting at 101MB/sec. and decaying to about 50 (average is about 80 MB/sec.). That is more than my old Hitachi 1TB drives. Of course access time is high, typical for the 5400 RPM drive that it must be. It is fast enough for large data files and...
You ordered it already? We should not be surprised.;) I will wait for a while.
I can't do much with computers until my injuries have healed to a reasonable degree. :(
That is interesting, yet nothing is near the X25-E in writes. I wonder if some of the reason for good performance is that it is a 32GB drive with extra, hidden space rather than 40GB (half of the MLC X25-M)?
So where is the 64GB X25-E? I want one now. 32GB is really not enough.
I understand that the various features would be useful in some huge forums. Yet the settings and pull-down menus are all so confusing to the likes of me. ;)
I check SF every chance I get, and post too often. :) I don't miss too many threads unless on travel.
I guess everyone has different priorities. I'd rather spend money on a lens, RAID card, or something else of tangible value. Of course I never had any interest in that sort of thing.
I don't have the 24", but I know a few users that I trust on that one. I'm not sure how important the gamut is to you. One of the overpriced 30" displays I bought had an insanely large gamut, but did not map all that well to printed output.
I don't care so much about color accuracy. However, local brightness uniformity, viewing angle effects, grayscale gradation, and contrast at reasonable brightness levels (120 not a crazy 400-500) are problematic.
In the 24" size, the NEC LCD2490WUXi or displays with the same panel are probably the best for 2D. It has better angular uniformity than the larger displays.
It sucks now. :( I have not been able to find anything I like better than a nearly 4-year old display that is starting to die. $3000 and nearly another $5000 and then rejected. I gave up for a while.
So the write speed for an average (1GB) file would be equal to the PCIe slot speed, not the SATA interface speed? Of course writes would slow down eventually and reads would be no better than usual.
Do they support hot swap (power on/off) for individual drives? I would not be using arrays.
Is there any reason not to buy one other than obsolescence of SATA 2.0?
I almost ordered the 1.5TB WD drive from the rotten egg. Fortunately, I waited and now see that they are up to the old trick of misrepresenting an OEM product as a retail one.
It is probably best to wait a few months and see what develops in large HD land.
