Pros: I just can't say enough good about these drives. I really, really like them. The four I purchased back in 2011 are still going strong. I thought I was having problems with one of them and purchased another to replace it, but it turned out the problem was on the controller side and so all five drives are in great shape. I tested the drive in question extensively and could not break it. They run cool, perform fast and are very dependable. I am extremely happy with them ...
Cons: Certainly none in my case. Cons for some users might be that they don't fit in a notebook or other mobile type device that use notebook drives. Additionally, they cost more than the usual notebook or desktop drives. But they deliver.
Summary: Honestly this isnt a con... its just an issue because Newegg has had these things listed in the wrong filter for so long... They have been in here since the original Constellation drives were made available on Newegg.
Pros: These drives are NOT laptop hard drives... despite them being filtered into that category by Newegg. They are desktop/ enterprise class hard drives specifically made in the 2.5" form factor.
Cons: This, as well as all the constellation drives will not fit into your laptop, so please bear that in mind before purchasing them. They are much taller than a standard 2.5" drive. 15mm is the listed maximum height of all the constellation drives according to Seagate. That also means that some of the hot-swap solutions out there wont accept them. 0.591"/ 15.00mm is much larger than the standard 9.2mm so you can see the issue.
Pros: I liked these drives so much, I bought two more. They seem to run very cool and performance continues to dazzle.
Cons: The issue with occasional initialization failures continues. It is due to the old 3ware controllers not being able to reliably step the speed down from SATA3 to SATA1 level. It is not any fault on the part of the drives themselves or the controller, for that matter. 3ware specifically does NOT support their use with older controllers designed before all the SATA specs were completely sorted out, so I am on my own. They might have the same problem with other older cont...
Pros: These are sweet drives. I bought two from Newegg and installed them on an old 3ware 8006-2lp SATA1 RAID controller. I was a little concerned that the old controller would not be able to handle these SATA3 drives, but partitioning, formating, OS installation (linux) and several days use have not seemed to break anything. They are fast even on a SATA1 controller, I can't imagine what they would do on a SATA3 controller.
Cons: I am having the same irritating problem with these drives on the 3ware controller that I have had with other newer drives. Apparently these drives can attempt to do some brief housekeeping on initial access and the 3ware controller then fails on a drive not ready issue and goes into degraded mode which requires a resync if you don't catch it and abort the boot. I am wondering if their is some firmware option on the drive that will disable this feature on the drive.
