November 10, 201510 yr I just posted this deal to slickdeals.net, and wanted to share it here as well. Crazy cheap price for this drive. Comes out to around $22.17 per TB. It also comes with a 3 year warranty, which is cool. http://slickdeals.net/f/8232764-seagate-archive-8-tb-internal-hard-drive-177-35-shipped-jet-com-new-customers?p=79342642#post79342642
November 10, 201510 yr What kind of effects can we expect because this is an archive drive vs a regular one?
November 10, 201510 yr Author What kind of effects can we expect because this is an archive drive vs a regular one? Check out this post: https://lime-technology.com/forum/index.php?topic=39526.0 TLDR: It seems to be on-par with a WD Red.
November 10, 201510 yr Thanks for that! I assumed someone did a write up. Thanks for posting it for me! Maybe I'll get one?? hmm....
November 11, 201510 yr Jet is terrible if you ever need warranty service since Jet basically takes your money and then has your item drop shipped form another retailer. Too bad amazon didn't match this price, I'd love to remove a 1.5TB drive and move my current 6TB drive into the array. What are the temps like on these drives compared to WD Reds?
November 13, 201510 yr I just got my first drive today.. Starting the pre-clear now.. I don't want to think about how long it's going to take to pre-clear this sucker! My second one is supposed to come on Monday. Hopefully the pre-clear will be done by then! Now I'm going to have to drudge through this forum to remember the best way to upgrade a parity disk!
November 13, 201510 yr When you have found how to upgrade the parity drive please post some links as I have to do the same. Sitting on parity plus eight 2TB drives wanting to upgrade them I have to do the same and one reason I have yet to upgrade the drives.

Sitting on parity plus eight 2TB drives wanting to upgrade them I have to do the same and one reason I have yet to upgrade the drives. 1 - Shutdown server and replace parity disk 2 - Start server, assign new parity and start array to begin parity sync Recommend not writing to the array until parity sync is complete, if anything goes wrong you can use old parity to do a new config. edited to better detail step 2
November 13, 201510 yr has anyone used this as a parity drive? i thought it was called 'archive' because its good for writing to, however rewriting is super slow. not sure if this correct... would love to hear about performance from anyone using it as parity
November 13, 201510 yr This pre-clear is going to take a while.. 137MB/s, 132MB/s, and 125MB/s for the 25% 50% and 75% points of the pre-read. It seems like it's going to be like 16-18 hours just for the pre-read! I am going to use this archive drive as a parity drive justified by the link in the post above. Jim

Jim My 6TB Seagates take forever too. They're big drives There's a faster pre-clear script floating around here that increases the post-read speed, but I haven't used it yet.

November 13, 201510 yr https://lime-technology.com/forum/index.php?topic=39526.msg368991#msg368991 cool thanks. this will be my next drive!
November 13, 201510 yr Author It works well! Would you mind linking to that script? My drives arrive today, so I'll start my preclear tonight. Edit: Nevermind, found it. http://lime-technology.com/forum/index.php?topic=32564.0
November 16, 201510 yr Ok.. Pre-clear took 60 hours! ouch! The parity synch seems to be taking longer too. Maybe once this is done, I'll resynch my old parity drive for a time comparison. It's almost at the 4T mark and it's about 14 hours into it.. I swore my old numbers were about 12 hours.. hmmm.... Jim

Jim I doubt that the 8TB Seagate is slower than the old 4TB disk, they are some of the fastest disks I used for parity check/sync, what’s probably limiting your speed are the older disks or a controller bottleneck, this was my parity sync, and this server still has one 3TB WD green Toshiba 7200rpm, with all 8TB Seagates it would be slightly faster. Subject: Notice [TOWER7] - Parity sync: finished (0 errors) Description: Duration: 15 hours, 47 minutes, 30 seconds. Average speed: 140.7 MB/sec

I wish I had those speeds! lol I'm really tempted to go back to the 4T parity drive just to see how long that would take.. then it would be an apples to apples comparison. But I don't know that I want to put that extra stress on my system and have my array be unavailable for another day! But I am dying to know! I don't know what to do! *pout* I do have some older 2T and 3T disks in my system and I only have the older saslp controller (3Gb/s only I believe or was it 1.5Gb/s)
November 16, 201510 yr It takes longer to do a parity check because before it was only checking up to 4TB, and now it's checking up to 8TB. Even if you have no >4TB array drives it will still take longer. I have a 6TB parity and my largest array drive is 4TB and it still checks those extra 2TB on the parity drive and takes forever.

I'm aware of that.. but I'm comparing to when it gets to the 4T point where my old parity sync would have finished.
