Seagate Constellation ES 1 TB 7200 RPM SAS 2.0 6 GB/s 16 MB Cache 3.5-Inch Hard Drive

I put 8 of these in my Enhance Box RAID enclosure using an ATTO R680 controller. I have the RAID control do a Media Scan with Verify every night. So far, 338 scans with no errors. I can't think of a downside. I bought these for video editing, so I do a lot of reads and writes. I bought an additional drive as a spare, and it looks like that was unnecessary. Priced right. Quality product.

Product came in very fast, installed in server. Power light came on and it spun up but had a flashing yellow light indicating an error and you can hear a slight clicking sound.

The media could not be loaded. I found out one of the drive on my Dell R720 RAID become Red over the weekend, and quickly order two of SAS Drive to replace it, the item arrived this morning, and put it to the caddy, plug-in, start to re-sync RAIDs with out even shut up the system. Works flawlessly.Item was packed with care, ship via Fedex,This drive costs hundreds of dollar years ago, now, it is a great value, I even jokes with my associates, the caddy that holding it, the price may soon surpass the drive.An Reliable drive to use on Servers, I have many of this drive on server, never give me any trouble for years.The Technology changes, but it still serves its purpose well. Great Buy!!

works good... but very likely used drives as it was dated 2011 as production date... and there were some faint scratches
