Im looking for storage options. Need 90Tb usable (approx 100Tb RAW) storage, prefer SAS and 10K RPM.
Need to sustain 200-500 MByte/sec throughput, 24/7 for 2-3 months.
Short term project.

I haven't used them but this company says they rent various IT equipment including disk arrays from Dell:

I know they've been around quite a long time because I've gotten emails from them for years and even spoke to them once.

You'd want to pay attention to the connection required (e.g. fibre, iSCSI, or even proprietary adapter like the Dell MD1220 requires) and make sure you have that (or get it as part of the deal) and an available slot in your server if a new adapter is required.

10 K SAS aint going to resolve you 500 MB/s no matter what brand you put in there.
SSD drive will do but without TRIM which I do not recommend , the speed will slow down shortly
What i do recommend is RAID 10 4x1TB samsung F3 spinpoint not anymore available which will generate just about 2 TB of usable drive space, 2 stripe matrices by mirroring one each other.You could use 4 x WD 1 TB blue edition without compromises too !
the average speed would be just about 200 - 250 Mbyte/s ( (200-250) * 8 Mbit/s)


For 90 TB space i just wish you luck in da future , hope your wallet can cope with it

I found a vendor called Backblaze which looks like it might work.
As for the speed, I need 500MB/s accross the 100Tb, not per device, so striping Raid5 7+1 disk groups might work ok.

A 24-drive RAID 60 with 6 TB drives would hit your size and speed requirements with plenty of redundancy.

I have three systems like this that I built/maintain. They use standard consumer grade drives (4 TB = 80 TB array) and Adaptec controllers. They can sustain 1 GB/s and have been running for 2-3 years 24/7 without any issues so far on any of them.

$1.5k for the chassis/PS, $500 for the mobo, $1.2k for the RAID card (72405) and BBU, a few hundred for a boot drive (or pair in a mirror), and about $300 per drive (consumer grade) or $500 per drive (enterprise) brings the total to $11-16k out the door.

Buy a few extra drives and keep them handy for hot-swapping failures and you should be set, at least against any normal drive failures. You could even use 22 drives for the array (108 TB) and the last two for hot-spares. A full system failure (eg: blown power supply that wipes out the rest of the system) will still knock it out like with any other though.
