MDD enterprise hard drives integrate the latest technology in support of a scalable, secure, and reliable cloud data centre. Specifically designed to work in highly scalable environments requiring low power consumption and weight, the MDD hard drives perform consistently while scaling to meet the stringent TCO requirements of most cloud-based data centres.

I have never been willing to buy a refurbished drive. They are mechanical devices which wear out. However, having bought a refurbished server that requires four drives to set up a decent raid, it suddenly began to make sense. The drives cost $30 piece. If one fails I'll buy another one for $30. And being that they are SAS datacenter drives, they are made to have a longer life than consumer SATA drives. So far these drives have all performed trouble free.

Once more received the items correctly, needed a few more so I ordered some in good confidence. No transport damages, are recognized correctly and working as hoped and expected. My NAS is now a trustworthy machine once more.

One word of caution which has nothing to do with this device, but with NEW SATA and SAS devices in general. If you have an older power supply which supplied voltage to pin 3 of the SATA/SAS power connector, NEW devices will NOT power up and you'll think HDD or the interface is faulty. Can be easily fixed with an adapter such as Cable Matters 3-Pack 4 Pin Molex to Dual SATA Power Y-Cable Adapter- 6 Inches which fixed the problem for me.I gave it 5 stars but one of the devices could not be formatted and the device itself was listed as read only. Sent it back and the replacement arrived in about 10 days and is working fine.

I took a gamble with these since they are refurbs of an unknown-brand from an unknown refubisher with not reviews, but the listed specs and price were just too tempting. Since these are supposedly enterprise-grade, are SAS, are backed by Amazon's renewed program, and will be part of a RAID array with ample additional backups anyway I bit the bullet and purchased two. So far they are exceeding expectation except for a couple annoyances.1. Unpackaging. First annoyance, the sticker says they are 6GB/s SAS, but the listing was for 12GB/s SAS. A message to the seller confirms they should be 12GB/s. I can't confirm until I upgrade my controller, but really that's minor considering these are spinners anyway not SSD, and the price is amazing even if 6GB/s.2. SMART: Out the gate, I examined with smartctl -a and found my only gripe. These report as new drives, low runtime, and have the original manufacturer and model replaced by the refurbisher's info, which can't be real. Refurbished or not, do not tamper with SMART data! Not great, and could be used to hide something bad, so this made me want to do a lot more testing. "smartctl -t long" passed no errors at least.3. f3probe: Usually f3 is used for finding fake capacity flash drives, but it works for HDDs too. No issues there. I didn't use f3write/f3read but may on another drive. Will update if so.4. Full write/read tests, 2 methods: Since I bought two I used two methods for this.First drive, I used the standard badblocks command. No issues and took a few hours.badblocks -b 4096 -c 65536 -t random -wsv /dev/sdbSecond drive, I used the supposidly faster and more reliable "luks + shred + cmp". First, luks encrypt the drive, then write all zeros with shred, then compare this to /dev/zero with cmp. No issues here either, it just took 3x as long as badblocks.cryptsetup open /dev/drivetest name --type plain --cipher aes-xts-plain64shred -v -n 0 -z /dev/mapper/drivetestpv /dev/mapper/drivetest | cmp -b /dev/zeroI am now in the process of replacing older drives in my BTRFS RAID array with these. So far with all of the reading and writing the SMART errors have not shot up. Looking good so far. Read-write performance is great and outperforms my other drives. I'll update again in a few weeks if they survive (or not). A rebalance and scrub are still in order after the replace process completes. If they survive a few weeks I'll rebalance the RAID level from 1C3 to 10/4 to get a little more usable space.Other thoughts: I may test one with Spinrite level 4 later just to see if it finds anything unusual.Only reason I'm giving the 4 stars for now instead of 5 is the SMART and label issues. If they survive several weeks this will be reconsidered.
