4 out of 5 eggsFast, tough drive.

Pros: Okay this is a VERY fast drive. As others have said, you do NOT use this for storage. You use it as a system boot drive, or in cases where disk performance MATTERS.
My current Cheetahs were originally a server boot array. However, now that the machine it's in rocks an SSD they have been relegated to drives for my SQL Server implementation (one drive for the data file, another for the log file).
Having used high speed SCSI drives for years, I was pleasantly surprised at how quiet and cool these things run. I have mine in an un-soundproofed case not 3 feet from my head and I can't even hear it.

Cons: Wish I could get 15K in multi-TB sizes. But oh well.
SSDs have wholly surpassed these drives in terms of performance, SOMEWHAT diminishing their value.

Other Thoughts: As others have noted. If you're looking for bulk storage drives, you don't want these. Look elsewhere.

If you're in a write-heavy environment (where you can burn out an SSD), consider these drives (and their 600GB cousins) as an alternative.

5 out of 5 eggsExcellent Performance

Pros: This is a high performance, server-grade mechanism that combines a reasonable price with capacity, speed and reliability. We installed this drive into a server running SUSE Linux and noted better than average throughput in a mix of small file reads and the large reads that occur when a program is loaded and executed. The large cache helps to decrease frequent medium accesses, which improves throughput to a considerable extent.

During server builds we performance a detail surface analysis on all new drives and examine both the factory and grown defect tables. This mechanism had a low incidence of factory defects and following a hard format, no grown defects.

Cons: No defects or other issues were noted with this product.

Other Thoughts: We have been using Seagate SCSI drives in our servers (and a few high end workstations) since the latter 1980s and have had exactly two premature failures (one an infant mortality) out of several thousand drives shipped. These are trustworthy products that will easily exceed Seagate's advertised service life rating if correctly installed.

Note that all SAS drives are intended for server duty and do not incorporate design features intended to mitigate noise. Also, these drives must be forced-air cooled if rated life is to be achieved. Shock-mounting is recommended. As these drives have write caches, it is essential that the server be powered from a UPS and have monitoring software loaded and running to cause an orderly shutdown if power fails. If power to the drive is removed before the write cache is flushed data will be lost. Therefore, an orderly shutdown is essential.

5 out of 5 eggsSAS Drives

Pros: Unkike EJ on page one of the reviews you dont use these drives for STORAGE they are Windows or OS drives. that is why you buy a 3 TB for under $200.00 or a 4 TB for under $300.00.....

I have a 15.7k 300 GB Windows and the 3930k CPU Clocked to 4.8 Ghz, 64 GB Memory and the nVidia GeForce 680 GTX and Windows performance index although I dont think much of it reports a 7.9 all the way down. and 99% of the bottlenecks occur at either memory, CPU Cache or Drive Read / Write for the OS.

Cons: Expensive but worth it

Other Thoughts: you will find me in the OC and ROG forums as well

5 out of 5 eggsCheetah Performance

Pros: I have owned many of these Serial Attached SCSI (SAS) Drives. They are the only Manufacture that makes it tight and right with the highest of quality and performance, I am running this drive on an LSi 9207 4e / 4i Host Controller, using this drive for my Windows 7 Professional 64 Bit system drive. My average boot time after the LSi Controller and Drive loads is 8 Seconds sometimes shorter rarely longer. I have it mounted in its own 3 drive Bay as a single drive mounted in the center bay at the rear of the case. This is to maximize cooling space around the drive, the Drive cage also provides a mount for a 3 inch Fan, I chose the 12v 4000 RPM Fan to extract the air out of the case, by the way is a Lian-Li 343B Cube where the main board mounts in the center of the case with all of the storage racks are on the Right Side and all of the electronics are on the left side which separates the heat and is much more efficient in heat evacuation. My Storage drives are all Seagate constellation 7200 RPM Drives & Support the 6.0 Gps SATA specification w/ a 64 MB Buffer These drives are mounted in a Hot Swap Cage and occupy 3 5.25 external Drive Bays also with a 90mm High volume mid speed fan. The LSi Controller supports one male cable end which handles the power and data through one 4 leg cable w/ 4 one piece connectors that I can add 3 more drives, which I would never do a/o who needs that kind of performance for Storage drives. The Controller setup is fairly easy if you are experienced in the old school 'Small Computer System Interface" architecture otherwise know as "SCSI" it operates in exactly the same way. You must load the driver using the F6 option during the Windows 7 install which is now the "Load Driver" option and will support Thumb Drives as well as Optical Drives. Once that is done you will see your drive appear in the "Installable Drives Box" I do recommend disconnecting all other storage drives you have connected this is for 2 reasons.
1. You wont run the risk of installing the Operating System on the
Wrong Drive
2. It will Align your drive letters in the proper order ie:
C:\ Windows System
D:\ Optical drive
Then after the install when you plug in your storage drive(s) they will appear as E:\ and up.

Cons: Ya gotta bust out your wallet for this type of configuration but very worth it if your building a high end system I gaurantee you wil not be bottle necking in the drive department.

My performance rating is a straight 7.9 all the way down

Other Thoughts: If you want a top of the line system buy this hardware

4 out of 5 eggs

Pros: Good, dependable drive. We use these in all of our our clients servers (300 and 600 gig models) and they all perform well. You pay more as server quality parts are pricey, but you get what you pay for and you need to pay for some reliability.

Cons: No real CONS to speak of.

Other Thoughts: The drives will wear out and fail, it's a given if left in use for long enough, nature of the beast, be prepared to update/upgrade your gear along the way. We try to replace them by the 5 year mark, but have many in service past that age, only one I can think of has failed earlier than 3 years, but that's out of well over 100 that we have used in our builds.

5 out of 5 eggsI have this in my worksatation at work

Pros: The drive is very robust, I read and write about 100 GB of data per day. Very good speeds, it has SSD like performance for small files and speeds of 160 GB/s for large transfers. Good price to GB ratio when compared to SSD drives.

About 20 people were I work have this HHD in their computer and I have not heard on any failures.

Cons: Too small for my work load. I can only have 1 to 2 projects on my workstation at a time. If I had a say in my own workstation I would do raid 5 with 2TB drives which would give me better performance and a lot more room.

Power usage: 8.75 (idle) to 12.92 Watts (average operating)

Other Thoughts: Some Benchmark info from my drive:
4KB Random Read: 34,747 IOPS
4KB Random Write: 33896 IOPS
Max Read: 163 MB/s
Max Write: 166 MB/s

5 out of 5 eggsExtremely Reliable Enterprise Server Disk

Pros: Bulletproof reliability, fastest line of non-SSD disks on the planet.

Cons: Higher cost per GB than SATA, but you get what you pay for.

Other Thoughts: My dayjob is server admin at the datacenter level. All of our rackmount servers run 4 Seagate Cheetah 15k rpm SAS disks per machine, and the failure rate is near zero even on servers where disk I/O is very heavy all day long. Our experience is you will retire the server due to obsolescence before these disks fail.

1 out of 5 eggsNewegg playing foul game

Pros: Unable to determine because hard drive was shipped defective. This review is actually for newegg customer service.

Cons: newegg customer service is a big cons. If newegg send you a bad product and you ask for an rma and then tells you when you sent the product back for rma that they don't sold that particular product, then who's fault is it????? How would you feel if you just spend $300 for a brick hard drive!!!!!!!!!!!!!!

Other Thoughts: newegg shipped this drive to me defective. asked for rma, sent drive back, just to learn that they will not replace the drive because they didn't sold the drive. If that is the case where do I stand right now? They sold me a brick and I am on my own! Way to treat your customer newegg who happens to spend a lot of money buying parts from you. Obviously somebody may have switched that drive in your end, because this is the first time I am building a SAS system.
