Hitachi GST Ultrastar 15K300 HUS153030VLS300 (0B22132) 300GB 15000 RPM 16MB Cache Serial Attached SCSI (SAS) 3.5″ Hard Drive Bare Drive

Pros: Running 10 of these in a raid 5 setup with a Adaptec 5805 in a Virtual production, currently hosting 4 MSSQL databases and I must say havent run into a issue yet

Cons: None,

Overall Review: excellent, could come down in price a bit, but Oh well

Pros: Cheap 15k drive.

Cons: I have standard 68 pin SCSI Seagate Cheetah 15ks on another workstation and they are great. They are crazy expensive however. Thought I had found a steal with these drives and the onboard SAS controller of the P6T6 however, the controller won’t recognize the drives. Sent them back for a pair of Velocirptors.

Overall Review: They might be great – thus the not giving them a 1 egg rating….but they sure don’t work with Asus P6T6 WS…or at least mine. One other thing – I’d plan on cooling these…got hotter than he||…much hotter than my Seagates.

Pros: Inexpensive for a 15k drive
Reliable, especially for a 15k drive

Cons: The overall small capacity of the drive, while not in itself an issue given the price, means that you will fill up a RAID controller fairly quickly.

Overall Review: We purchased 4 of these for use in our production server. I set them up in RAID 10 over RAID 5 and we’ve been getting amazing throughput. Relative to the two 750GB 7200 RPM drives that were in RAID 1, there’s no comparison.

15k drives can be a bit temperamental to any loose screws in the mounting – make sure to tighten down all your components so that you avoid vibration as much as you can.

Pros: Hitachi drives are the best on the market in SATA and SAS and SCSI, especially the enterprise models, but I have never had a consumer Hitachi fail either, and I have had hundreds of Seagates fail, and to a lesser amound, WD’s.

Cons: none, don’t own it yet, but all my failure are now Seagate and lower end WD.

Overall Review: this was prompted by daveinca giving a low rating b/c his controller would not see the drive, pretty dumb dave. Try another controller b4 commenting next time. Hitachi’s are the best drives made. IBM drives for years were from Hitachi. The only one I had fail in 15 years was an older 4.5 gig SCSI which I dropped on asphalt, spilled coke on,and my puppy chewed on it in the mud..and it still ran for a year after that, tested it to see after failing to another drive for backup.
