5 out of 5 eggsSolid Dive

Pros: This Dive is solid as a rock. You can not bet the 5 year Manufacturer Warranty. I have mine on 24x7x365 with no down time. but even more the 128MB Cache this is top of the Line.

Cons: So I have order 100 of these drives over the last 2 years, and found a new drive fail rate of 4% with in the first 3 months.( Don't Return it to Newegg use the Manufacturer Warranty From Seagate. They can overnight the Drives. Just be Nice and let them know it is time sensitive) Then the fail rate drop to next 0% after that. I can't ask for anything better.

Other Thoughts: SAS is not SATA this is just like WIFI is not Ethernet.
Just because they do the same thing dose not mean they are the same!

How Can you Tell what you need SAS or SATA?
in SATA Drive you will see a clear air Gap in the pin bar.
in SAS drive looks like a sata but there is NO air GAP in the pin bar. So that is one solid Pin bar.
There are some other ways to tell but this way is the most straight forward.

6Gb/s SAS is O, So nice in the RAID.

5 out of 5 eggsEnterprise Drive

Pros: This is an enterprise drive intended for servers and workstations. Sustained R/W of 175mbs. 5 year warranty!

Cons: Uninformed people... Really, people rating this drive bad because they are confused about what SAS is. User error has nothing to do with how well this drive preforms. They even make a SATA version!

Other Thoughts: Some people shouldn't be fiddling with their computers.

1 out of 5 eggsWhat SAS Means, versus SATA

Pros: SAS Interface

Cons: Not SATA Interface

Other Thoughts: You cannot connect an SAS drive to a SATA drive bay or connector. There is a plastic key that prevents you connecting one to the other. So, in spite of the fact that NewEgg insists on listing this ST2000NM0023 as SATA 6Gbps, it is not and you will need to chat into newegg support to get an RMA and return it.

I gave the LISTING the one-star. The drive itself will be great for whoever can use it.

5 out of 5 eggsThese are SAS

Pros: not tested yet

Cons: not tested yet

Other Thoughts: The drives have just arrived, so not yet tested. Despite the product description saying SATA, these are SAS drives. The Seagate part number is also for SAS. New Egg also sells the SATA version for a slightly lower price.

I will update my review after testing
